Kanker serviks merupakan jenis kanker yang paling banyak dialami oleh wanita di Indonesia. Gangguan pada proses apoptosis merupakan tahapan yang penting dalam perkembangan tumor dan menyebabkan sel tumor lebih resisten terhadap terapi sitotoksik konvensional. Protein antiapoptosis Bcl-2 merupakan protein yang berperan penting dalam proses apoptosis yang bisa dijadikan molekul target obat antikanker. Asam galat merupakan senyawa penuntun yang telah terbukti secara in vitro memiliki aktivitas sebagai anti kanker. Penelitian ini bertujuan untuk mendesain, mensintesis dan menguji aktivitas sitotoksik turunan asam galat terhadap sel HeLa. Desain turunan asam galat dilakukan dengan metode structure based drug design untuk mendapatkan senyawa turunan yang menghambat protein anti apoptosis Bcl-2 dengan lebih baik. Lima senyawa turunan asam galat yang memberikan nilai ΔG terkecil dipilih untuk disintesis. Tiga senyawa turunan asam galat disintesis dengan reaksi kondensai dengan alkil halida, sedangkan dua turunan yang lain disintesis dengan reaksi esterifikasi menggunakan katalis DIC dan DMAP. Senyawa hasil sintesis diidentifikasi dengan menggunakan spektrofotometer FT-IR, Spektrometer massa, 1H-NMR dan 13C-NMR. Senyawa hasil sintesis dilakukan uji sitotoksisitas dengan metode MTT. Hasil pengujian sitotoksisitas menunjukkan bahwa tiga turunan ester asam galat memiliki aktivitas penghambatan yang lebih besar pada sel HeLa dibandingkan dengan asam galat dengan IC50 berkisar antara 30,20-34,43 μM. ......

Surgical site infections are the second most frequent nosocomial infection after catheter infection. They are associated with increase morbidity and mortality, iength of stay in hospital and cost of care. Antibiotic prophylaxis use is addressed to reduce incidence of surgical site infection. The aim of this research was to find out the pattern of antibiotic prophylaxis use; incidence of surgical site infection; association between antibiotic prophylaxis use and incidence of surgical site infection; and other factors that influence the incidence of surgical site infection. This research was carried out in Dr. Cipto Mangunkusumo Hospital Jakarta and it was a retrospective study with cross-sectional design. A total of 220 samples had been taken proportional randomly according to the type of surgery division from 1,841 medical records in 2005. The result showed that the most antibiotic prophylaxis frequently used was cephalosporin (first and third generation). followed by phosphomycin and metronidazole. Most of the patients were given antibiotic prophylaxis in inappropriate time and the duration of use was more than one day. This study found that the incidence of surgical site infection was 8.6% with the highest percentage occurred at orthopedic surgery (23.3%). Statistically, there was no relationship of class. Timing and duration of antibiotic prophylaxis use with incidence of surgical site infection. Adherence of antibiotic prophylaxis use to hospital guideline was not influenced the incidence of surgical site infection. Multivariate analysis with logistic regression analysis showed that the incidence of surgical site infection were influenced by the type of surgery (OR=2.6) and the use of antibiotics during hospitalization prior to surgery (OR=3.2). The conclusion of this research were the incidence of surgical site infection relatively high and class. timing, duration and adherence to hospital guideline of antibiotic prophylaxis use did not influence it. The wound contaminated and the use antibiotics during hospitalization prior to surgery were risk factors for surgical site infection. It was recommended that the hospital management revise the currently used surgical antibiotic prophylaxis guideline which is no longer relevant to the current situation.

Abstrak :
Penelitian ini melakukan optimasi metode analisis penetapan kadar sisplatin secara kromatografi cair kinerja tinggi melalui derivatisasi menggunakan pereaksi dietilditiokarbamat untuk meningkatkan selektivitas dan sensitifitasnya terhadap detektor Uv-Vis, karena senyawa sisplatin tidak mempunyai gugus kromofor yang dapat terdeteksi oleh detektor ultraviolet. Menentukan kadar ondansetron hidroklorida dalam sampel dicobakan mengoptimasi penggunaan kolom fase terbalik C18 yang belum umum untuk penetapan kadar ondansetron. Sisplatin mempunyai efek samping emetogenik kuat yang dapat di hambat oleh ondansetron melalui inhibitor reseptor 5-HT3 yang sangat efektif untuk pencegahan mual dan muntah selama kemoterapi sisplatin yang diberikan secara terpisah melalui intravena. Pemberian antiemetik bersamaan dengan kemoterapi dalam satu rute pemberian diharapkan lebih efektif dan efisien untuk penanganan kemoterapi kanker. Pemberian dalam satu rute secara bersamaan harus dilakukan evaluasi stabilitas kimia campuran sisplatin dan ondansetron hidroklorida dalam satu larutan infus NaCl 0,9 % selama 24 jam kemoterapi kanker. Sisplatin dianalisis menggunakan kromatografi cair kinerja tinggi melalui derivatisasi dengan pereaksi natrium dietilditiokarbamat 10% dalam NaOH 0,2N. Derivat sisplatin-dietilditiokarbamat dielusi menggunakan fase gerak asetonitrilair (70:30 %v/v) dengan kecepatan alir 0,8 ml/menit pada kolom Knauer® C18-RP (250 x 4,6 mm, 5µm). Ondansetron hidroklorida dianalisis dan dipisahkan menggunakan kolom Sunfire Waters® C18-RP (25 cm x 4,6 mm, 5 µm) dengan fase gerak KH2PO4 50 mM (pH 7) dan asetonitril (75:25 %v/v) dengan kecepatan alir 2 ml/menit dan dideteksi pada panjang gelombang 249 nm. Stabilitas kimia kedua obat selama 24 jam dievaluasi dengan membuat campuran larutan injeksi sisplatin 92,42 ppm dan ondansetron HCl 59,15 ppm dalam larutan infus NaCl 0,9 % yang disimpan pada suhu 27°C dibawah cahaya ruangan normal.

Abstrak :
Pendahuluan –Diabetes Mellitus tipe 2 (DMT2) merupakan sindrom inflamasi progresif dengan peningkatan risiko komplikasi kardiovaskular berupa Atherosclerotic Cardiovascular Disease (ASCVD). Proses thromboinflamasi pada DMT2 ASCVD dikaitkan dengan perubahan pada jumlah serta fungsi leukosit dan trombosit. Rasio leukosit (Neutrophil-Lymphocyte Ratio, Monocyte-Lymphocyte Ratio, Platelet-Lymphocyte Ratio) serta penanda biologis dari netrofil (Peptydil Arginine Deiminase-4), monosit/makrofag (Interleukin-6), dan trombosit (Platelet Glycoprotein 1b-α) dikenali sebagai penanda biologis yang dapat memprediksi perubahan plak stabil dan tidak stabil pada pasien DMT2 ASCVD. Studi ini dilakukan untuk menganalisis hubungan antara klasifikasi pasien DMT2 2 risiko sangat tinggi (Very High Risk / VHR) dan risiko tinggi (High Risk / HR) dan pada pasien DMT2 dengan Acute Coronary Syndrome (ACS) terhadap parameter inflamasi NLR, MLR, PLR, GPIbα, PAD4, dan IL-6. Metodologi – 75 pasien DMT2 ACSVD yang menjalani pengobatan di rawat jalan dan unit gawat darurat Rumah Sakit Pusat Jantung dan Pembuluh Darah Harapan Kita dilibatkan dalam studi ini. Pasien dikategorikan sebagai DMT2 risiko tinggi, DMT2 risiko sangat tinggi, dan DMT2 ACS. Parameter metabolisme dan inflamasi diukur dan dianalisis pada ketiga kelompok DMT2 ASCVD tersebut. Hasil dan Diskusi – Nilai parameter metabolisme kolesterol total dan Low Density Lipoprotein (LDL) serta parameter inflamasi NLR, MLR, PLR, dan IL-6 ditemukan lebih tinggi dan signifikan pada kelompok DMT2 ACS. Nilai Gp1bα ektodomain (Glikokalisin) ditemukan lebih tinggi pada kelompok DMT2 risiko tinggi dan DMT2 risiko sangat tinggi menggambarkan hubungan Gp1bα dan ADAM17 yang terkait dengan keseimbangan pembentukan dan pembersihan trombosit. Nilai PAD4 yang lebih tinggi pada kelompok DMT2 risiko tinggi dan DMT2 risiko sangat tinggi menggambarkan proses perbaikan jaringan dan induksi polarisasi makrofag menjadi fenotip antiinflamasi yang berperan terhadap perbaikan fungsi kardiovaskular. Penelitian ini menunjukkan bahwa nilai NLR dan kolesterol total yang tinggi serta nilai PAD4 yang rendah merupakan prediktor terjadinya keadaan ACS (plak tidak stabil) pada pasien DMT2 ASCVD. ......Introduction – Diabetes Mellitus type 2 (T2DM) is a progressive inflammatory syndrome with an increased risk of cardiovascular complications in the form of Atherosclerotic Cardiovascular Disease (ASCVD). The thromboinflammatory process in T2DM ASCVD is associated with changes in the number and function of leukocytes and platelets. The leukocyte ratio (Neutrophil-Lymphocyte Ratio, Monocyte-Lymphocyte Ratio, Platelet-Lymphocyte Ratio) as well as biological markers of neutrophils (Peptydyl Arginine Deiminase-4), monocytes/macrophages (Interleukin-6), and platelets (Platelet Glycoprotein 1b-α) are recognized as a biological marker that can predict stable and unstable plaque changes in T2DM with ASCVD. This study was conducted to analyze the relationship between the classification of T2DM patients with very high risk (VHR), high risk (HR), and early onset ACS on the inflammatory parameters NLR, MLR, PLR, GPIbα, PAD4, and IL-6. Methodology – This study included 75 ACSVD T2DM patients being treated at Harapan Kita Heart and Blood Vessel Center Hospital's outpatien and emergency unit. Patients were classified as having high risk T2DM, extremely high risk T2DM, or ACS T2DM. In the three T2DM ASCVD groups, metabolic and inflammatory parameters were evaluated and studied. Results and Discussion – The metabolic indices total cholesterol and Low Density Lipoprotein (LDL), as well as the inflammatory markers NLR, MLR, PLR, and IL-6, were shown to be greater and significant in the T2DM ACS group. Gp1b ectodomain (Glycocalysin) values were found to be greater in the high risk T2DM and very high risk T2DM groups, demonstrating the relationship between Gp1b and ADAM17, which is associated to platelet production and clearance balance. Higher PAD4 values in the high risk T2DM and very high risk T2DM groups represent tissue repair and the activation of macrophage polarization into an anti-inflammatory phenotype, which contributes to improved cardiovascular function. According to this study, high NLR and total cholesterol levels, as well as low PAD4 levels, are predictors of ACS (unstable plaque) in ASCVD T2DM patients.

Rubus fraxinifolius dan R. rosifolius merupakan tanaman Rubus yang dapat ditemukan di daerah pegunungan Indonesia. Kedua tanaman memiliki morfologi buah yang mirip yaitu berbentuk berry merah dan edible, serta mengandung senyawa golongan triterpenoid, polifenol dan flavonoid.  Beberapa spesies Rubus dilaporkan memiliki aktivitas sebagai antiaging yaitu antielastase, antioksidan, dan antitirosinase. Penelitian ini bertujuan untuk menelaah aktivitas antiaging secara in vitro pada ekstrak dan isolat dari tanaman R. fraxinifolius dan R. rosifolius. Batang, buah, dan daun kedua tanaman diekstraksi menggunakan alat Soxhlet serta dilakukan skrining aktivitas anti elastase dan antioksidan.  Selanjutnya terhadap ekstrak terpilih dilakukan pemisahan, fraksinasi dan isolasi senyawa. Isolat yang didapat diidentifikasi menggunakan spektrometri FTIR, 1H-NMR, 13C-NMR, DEPT, HSQC, HMQC, HMBC, dan LC-MS, serta diuji aktivitas antielastase, antitirosinase dan sitotoksisitas pada sel fibroblast secara in vitro. Hasil ekstraksi bertingkat menunjukkan bahwa ekstrak metanol daun R. fraxinifolius memiliki aktivitas antielastase dan antioksidan tertinggi dengan masing-masing IC50 57,45 dan 4,33 µg/ml. Terhadap fraksi metanol daun R. fraxinifolius (DFM) dilakukan pemisahan menggunakan kromatografi cair vakum dan diperoleh 11 fraksi. Uji antielastase fraksi menunjukkan fraksi paling aktif adalah DFM8. Selanjutnya dilakukan isolasi lebih lanjut terhadap DFM8 dan diperoleh 3 isolat. Hasil elusidasi struktur menunjukkan bahwa ketiga isolat merupakan suatu triterpen pentasiklik tipe ursan. Hasil telaah data pengujian DEPT, HMQC, HSQC, HMBC serta IR dan MS disimpulkan senyawa DFM 8a adalah asam 2,3-glikol, 19α-hidroksi-12-ursen-23,28-dioat (C32H48O7, BM 544); DFM8b asam 2,3-propanandiol, 19α-hidroksi-12-ursen-28-oat (C33H52O5, BM 528,38); dan DFM8c asam 2,3-glikol-19α-hidroksi-23,24-nor-12-ursen-28-oat (C30H46O5, BM 486,33). Ketiga senyawa hasil isolasi ini merupakan senyawa baru dan belum pernah ditemukan sebelumnya. Uji aktivitas antielastase senyawa DFM8a, DFM8b, dan DFM8c memiliki IC50 berturut-turut adalah 122,199; 98,22; dan 54,33 µg/ml, serta antitirosinase dengan IC50 207,8; 221,5; dan 335,9 µg/ml. Uji toksisitas menunjukkan bahwa ekstrak DFM, fraksi DFM8, dan isolat DFM8b tidak toksik terhadap sel fibroblas NIH/3T3.


Rubus fraxinifolius and R. rosifolius are Rubus genus, which can be found in the mountain of Indonesia. Both plants have similar fruit morphology: red and edible berries and contain triterpenoid, polyphenols, and flavonoids. Some species of Rubus are reported to have antiaging activity, antielastase, antioxidant, and antityrosinase. This study aims to examine the in vitro antiaging activity of extracts and isolated compounds from R. fraxinifolius and R. rosifolius. The stems, fruits, and leaves of both plants were extracted and screened for antielastase and antioxidant activity. Furthermore, the selected extracts were separated, fractionated, and isolated to yield isolates. The obtained isolates were identified using FTIR spectrometry, 1H-NMR, 13C-NMR, DEPT, HSQC, HMQC, HMBC, and LC-MS, and also were tested for antielastase, antityrosinase, and cytotoxicity activities in fibroblast cells. The continuous extraction results showed that the methanol extract of R. fraxinifolius leaves had the highest antielastase and antioxidant activity with IC50 57.45 ppm and 4.33 ppm, respectively. The methanol fraction of R. fraxinifolius (DFM) leaves were separated using vacuum liquid chromatography and obtained 11 fractions. The antielastase assay of fractions gave the most active fraction was DFM8. Then, further isolation of DFM8 was carried out, and three isolates were obtained. The structural elucidation showed that the three isolates were ursane-type of pentacyclic triterpenes. The results of DEPT, HMQC, HSQC, HMBC, IR and MS spectrometry test concluded that the compound DFM 8a was 2,3-glycol, 19α-hydroxy-12-ursen-23,28-dioic acid (C32H48O7, MW 544); DFM8b 2,3-propanandiol, 19α-hydroxy-12-ursen-28-oic acid (C33H52O5, MW 528.38); and DFM8c 2,3-glycol-19α-hydroxy-23,24-nor-urs-12-en-28-oic acid (C30H46O5, MW 486.33). All isolated compounds are new compounds and have never been found before. The IC50 of antielastase activity of DFM8a, DFM8b, and DFM8c were 122.199; 98.22; and 54.33 ppm, respectively, and the IC50 of antityrosinase activity were 207.8; 221.5; and 335.9 ppm, respectively. Toxicity tests showed that the DFM extract, the DFM8 fraction, and the DFM8b were not toxic to NIH/3T3 fibroblast cells.

Abstrak :
Peningkatan kebutuhan akan kosmetik saat ini berdampak terhadap meningkatnya tuntutan ketersediaan bahan baku kosmetik. Tanaman Soka Jawa (Ixora javanica) merupakan salah satu tanaman yang telah diteliti baik kandungan senyawa dan aktivitasnya, terutama bagian bunganya dan dapat digunakan sebagai kandidat bahan baku alami sediaan kosmetik. Disertasi ini bertujuan mengembangkan metode ekstraksi yang ramah lingkungan terhadap bunga Soka Jawa dalam rangka memperoleh sediaan kosmetik skin-lightening dan antioksidan yang berkualitas, aman dan efektif. Metode ekstraksi yang dikembangkan menerapkan prinsip green extraction menggunakan Deep Eutectic Solvent (DES) sebagai alternatif pelarut dan metode Ultrasound-assisted Extraction (UAE). Penelitian disertasi ini dilakukan secara eksperimental yang secara garis besar terbagi menjadi empat tahap penelitian yaitu tahapan skrining DES, optimalisasi kondisi ekstraksi, formulasi dan selanjutnya tahap evaluasi sediaan. Pada tahapan skrining DES, kombinasi kolin klorida dan propilen glikol (perbandingan molar 1:1) memberikan hasil perolehan senyawa serta aktivitas yang relatif paling tinggi dibanding pelarut yang lain sehingga dipilih untuk pelarut pengekstraksi bunga Soka Jawa. Hasil optimalisasi dengan bantuan statistik Response surface methodology (RSM) menunjukkan bahwa waktu ekstraksi 40 menit, penambahan air 25%, dan solid-to-liquid ratio 1:27 g/mL merupakan kondisi optimal untuk ekstraksi bunga Soka Jawa menggunakan DES terpilih dengan metode UAE. Ekstraksi pada kondisi optimal tersebut juga terbukti lebih efisien dibandingkan dengan pelarut etanol. Ekstrak DES bunga Soka Jawa yang diperoleh langsung diformulasi menjadi sediaan krim tanpa melalui proses pemekatan ekstrak. Hasil evaluasi terhadap sediaan krim menunjukkan bahwa sediaan krim yang diperoleh memenuhi spesifikasi sediaan dan terbukti stabil secara fisik, kimia, dan mikrobiologi. Berdasarkan hasil penelitian secara menyeluruh, dapat disimpulkan bahwa penelitian disertasi ini tidak hanya berhasil mengembangkan green extraction untuk ekstraksi bunga Soka Jawa namun juga memperoleh suatu ekstrak DES bunga Soka Jawa yang optimal sebagai bahan utama sediaan krim skin-lightening dan antioksidan yang berkualitas serta efektif dan aman secara in silico. ......The increasing demand for cosmetics has resulted in increasing of the need for cosmetic raw materials. Soka Jawa (Ixora javanica) is one of the plants that has been studied for its phytochemical and bioactivity, especially its flower and can be used as a candidate for natural raw materials for cosmetic preparations. The aim of this study is to develop an environmentally friendly extraction method for Soka Jawa flower in order to obtain quality, safe and effective skin-lightening and antioxidant cosmetic preparations. The developed extraction method applied the green extraction principle of using Deep Eutectic Solvent (DES) as an alternative solvent and Ultrasound-assisted Extraction (UAE) method. The main stages of this experimental study were DES screening, extraction methods optimization, cream preparation and its evaluation. The combination of choline chloride and propylene glycol (molar ratio of 1:1) showed the highest compound yield and activity compared to other solvents, therefore it was chosen as extraction solvent for Ixora flowers. The extraction method optimization using the Response Surface Method (RSM) showed that the extraction time of 40 minutes, the addition of 25% water, and a solid-to-liquid ratio of 1:27 g/mL were the optimal conditions for the extraction of Soka Jawa flowers using selected DES with the UAE method. The extract obtained under optimum extraction conditions showed higher extraction yields and activity than ethanolic extract which was used for comparison. The Ixora flower extract obtained was directly formulated into a cream preparation without going through the extract evaporation. The results of the evaluation of all parameters showed that the cream met the specifications and also proved to be physically, chemically, and microbiologically stable. In brief, it can be concluded that this study is not only succeeded in developing a green extraction method for Ixora flowers but also obtained an optimal DES extract of Ixora flowers as the main raw material for high quality skin-lightening and antioxidants cream preparations, and also predicted safe and effective in silico.
