ABSTRAK
Kanker paru-paru merupakan salah satu jenis kanker yang paling banyak diderita, terutama di negara dengan jumlah perokok dan tingkat polusi yang tinggi seperti Indonesia. Dalam beberapa tahun belakangan, perkembangan obat kanker paru jenis karsinoma bukan sel kecil diarahkan pada pengobatan multitarget karena pada pengobatan target tunggal sering kali proliferasi sel tumor dapat diaktifkan kembali melalui jalur yang lain seperti angiogenesis. Eksplorasi senyawa bioaktif dari bahan laut, termasuk fungi laut, telah mendapat perhatian khusus akhir-akhir ini sebagai pengobatan antikanker. Pada penelitian ini dilakukan pembuatan pangkalan data dan penapisan secara in silico untuk memperoleh senyawa aktif fungi laut yang berpotensi sebagai inhibitor EGFR-TK dan VEGFR2 kinase, yang masing-masing berperan sebagai agen antiproliferatif dan antiangiogenesis, menggunakan AutoDock dan Vina. Berdasarkan hasil penapisan, didapatkan tiga senyawa aktif sebagai inhibitor EGFR-TK (FU0015, FU0051, dan FU0202), satu senyawa aktif sebagai inhibitor VEGFR-2 kinase (FU0033), serta 17 senyawa potensi inhibitor multitarget (FU0018, FU0019, FU0028, FU0034, FU0037, FU0038, FU0029, FU0043, FU0079, FU0105, FU0127, FU0155, FU0156, FU0158, FU0248, FU0254, FU0261). Seluruh senyawa aktif tersebut berasal dari filum Ascomycota sehingga diharapkan dapat dilakukan eksplorasi lebih lanjut fungi laut dari filum Ascomycota.
ABSTRACT
Lung cancer is one of the most common type of cancer, especially in countries with high numbers of smokers and high levels of pollution such as Indonesia. In the past few years, drug development of non-small cell lung cancer has been directed to a multitarget treatment as oftentimes on a single-targeted treatment proliferation of tumor cells can be reactivated via other pathways such as angiogenesis. Exploration of bioactive compounds from marine materials, including marine fungi, for anticancer treatment has become a major concern lately. In this research, database was created and in silico screening was conducted to obtain potential marine fungi active compounds as EGFR-TK and VEGFR2 kinase inhibitor, for each act as antiproliferative and antiangiogenesis agents, by using AutoDock and Vina. Based on these screening results have been identified three active compounds as the inhibitor of EGFR-TK (FU0015, FU0051, and FU0202), one active compound as the inhibitor of VEGFR-2 kinase (FU0033), and 17 compounds that potentially become a multitarget inhibitor (FU0018, FU0019, FU0028, FU0034, FU0037, FU0038, FU0029, FU0043, FU0079, FU0105, FU0127, FU0155, FU0156, FU0158, FU0248, FU0254, FU0261). All of these active compounds are from Ascomycota phylum so that further marine fungi exploration can be conducted from Ascomycota phylum.

Marine-derived fungi have proven to be a rich source of cytotoxic compounds for the development of new anti cancer drugs. The aims of this research were to: 1) screen cytotoxic activity of marine fungi from Indonesian waters, 2) indentify marine fungus that produced that produced the most active cytotoxic compound and 3) investigate inhibition concentration 50 (IC50) value of cytotoxic compound. The fungi were isolated from marine organism collected from Wakatobi Marine National Park-South East Sulawesi, Binuangeun Beach-Banten, Manado watersNorth Sulawesi and Kepulauan Seribu Marine National Park-Jakarta. Liquid cultures of the fungi were carried out in Malt Extract Broth and Soluble Starch Soytone medium for 4 weeks at 27?28oC without shaking. Molecular identification of fungus was conducted through PCR amplificatin using primers of ITS1 and ITS4 primer. Cytotoxic activity of the extract was tested by using MTT (3-(4.4-dimethylthiazol-2-yl)-2.5-diphenyl-tetrazolium bromide) method. The MTT test showed that MFW39 strain exhibited the strongest cytotoxic activity. Molecular identification revealed that MFW39 marine fungus was similar to Emericella nidulans with precent identity of 99%. Mycelium and broth extract of MFW39 fungus inhibited the growth of T47D cell with IC 50 values of 21.9 and 169.3 µg/mL, respectively. Further research will be focus on to the strain of MFW39 marine fungi.

ABSTRAK
Menurut International Agency for Research on Cancer IARC, penderita kanker paru telah mencapai 1,8 juta jiwa dan 85 berkontribusi pada kanker paru jenis karsinoma bukan sel kecil. Dalam beberapa tahun belakangan, penelitian terhadap terapi tertarget sedang dikembangkan karena terbukti memiliki hasil terapi yang lebih efektif dan kemungkinan efek samping yang lebih sedikit. Perkembangan penelitian terhadap biota fungi laut belum banyak dieksplorasi dalam pengobatan kanker paru bukan sel kecil. Pada penelitian ini dilakukan simulasi dinamika molekuler pada senyawa biota fungi laut hasil penapisan virtual terhadap makromolekul EGFR FU0015, FU0051, dan FU0202 dan VEGFR-2 FU0033 untuk melihat aktivitas inhibisi sebagai agen antiproliferatif dan antiangiogenesis menggunakan AutoDock dan AMBER dalam suhu 300K dan 310K yang dibandingkan dengan kontrol positif EGFR Gefitinib, Erlotinib, and Imatinib dan VEGFR-2 Nikotinamid dan Vatalanib. Hasil simulasi dinamika molekuler terhadap inhibitor EGFR pada suhu 310K menunjukkan energi bebas MMGBSA dan okupansi ikatan hidrogen tertinggi dimiliki oleh FU0051 -43,72 kkal/mol; 98,80 diikuti oleh FU0202 -31.64 kkal/mol; 49,35, dan FU0015 -15,55 kkal/mol; 3,35. Fungi FU0033 sebagai bahan uji inhibitor VEGFR-2 pada suhu 310K memiliki nilai energi bebas MMGBSA yang lebih besar dibandingkan kontrol positifnya dan okupansi ikatan hidrogen yang rendah 0,15. Data penelitian menunjukkan senyawa FU0051 dan FU0202 memiliki potensi untuk menjadi calon agen antiproliferasi sehingga layak diuji in vitro.
ABSTRACT
According to International Agency for Research on Cancer IARC, the number of lung cancer patients has reached 1,8 million lives and 85 of the number contribute to non small cell lung cancer. In the past years, research on targeted therapy has been developed due to its efficacy and a small number of side effects. Research on marine fungi compounds has not been explored to non small cell lung cancer therapy. This research uses molecular dynamic simulation method to marine fungi compounds that have been docked to EGFR FU0015, FU0051, FU0202 and VEGFR 2 FU0033 as antiproliferative and antiangiogenetic agent by inhibition activity using AutoDock and AMBER at 300K and 310K temperature using EGFR Gefitinib, Erlotinib, and Imatinib and VEGFR 2 Nicotinamide and Vatalanib as reference standards. Molecular dynamics results for EGFR inhibitors at 310K shows the best MMGBSA free energy and hydrogen occupancy in FU0051 43,72 kcal mol 98,80 followed by FU0202 31.64 kcal mol 49,35 , and FU0015 15,55 kcal mol 3,35. FU0033 fungi as a material for VEGFR 2 inhibitor shows higher MMGBSA free energy in compare to its reference standards and low hydrogen occupancy 0,15 at 310K. This research shows that FU0051 and FU0202 have potential to be an antiproliferative agent candidate, hence in vitro test should be obtained.
