 Abstrak

Sitronelol dan geraniol dilaporkan mempunyai aktivitas antibakteri,antiinflamasi dan sitotoksik terhadap beberapa sel kanker. Hasil uji sitotoksiksitronelol dan geraniol terhadap sel kanker murine leukimia P388 menunjukkanbahwa, sitronelol dan geraniol mempunyai aktivitas sitotoksik terhadap sel kankertersebut. Untuk meningkatkan aktivitas sitotoksik, kedua senyawa tersebut dirancangmenjadi sejumlah senyawa ester dan diskrining virtual terhadap reseptor proteinproviral insertion site in Moloney murine leukemia virus-1 Pim1 kinase denganperangkat lunak Molegro Virtual Docker MVD . Hasil skrining virtual menunjukkanbahwa senyawa ester hasil rancangan mempunyai potensi sebagai antikanker dandisintesis 8 senyawa ester terpilih yaitu sitronelil kaproat, geranil kaproat, sitronelilisobutirat, geranil isobutirat, sitronelil 2,2-dimetil butirat, geranil 2,2-dimetil butirat,sitronelil kaprilat dan geranil kaprilat. Senyawa ester hasil sintesis dianalisis awalmenggunakan KLT, dimurnikan menggunakan kolom kromatografi, dielusidasistrukturnya menggunakan FTIR dan NMR serta dianalisis spektro massanyamenggunakan GCMS. Analisis toksisitas senyawa ester hasil sintesis dengan metodeBSLT menunjukkan bahwa, ester sitronelol dan geraniol hasil sintesis toksik terhadaplarva udang Artemia salina dengan nilai LC50 1,21-1,96 ?g/mL, sehingga berpotensisebagai senyawa antikanker. Hasil uji aktivitas sitotoksik terhadap sel murineleukimia P388 secara in vitro dengan metode MTT menunjukkan bahwa, estersitronelol dan geraniol hasil sintesis sitotoksik terhadap P388 dengan nilai IC50 10,63-37,69 ?g/mL. Aktivitas sitotoksik ester sitronelil kaproat yang disintesis dari asamkaproat minyak inti sawit sekitar 4 kali lebih kuat daripada sitronelol. Senyawa yangaktivitas sitotoksiknya lebih tinggi daripada senyawa induk, selanjutnya diujisitotoksik terhadap sel kanker payudara MCF7 dengan metode alamar blue. Hasil ujisitotoksik ini menunjukkan bahwa senyawa ester sitronelil isobutirat, sitronelil 2,2-dimetil butirat, geranil isobutirat dan geranil 2,2-dimetil butirat sitotoksik terhadapMCF7 dengan nilai IC50 1,32-4,83 ?g/mL.

Citronellol and geraniol have been reported as an antibacterial, anti inflammatory andcytotoxic against some cancer cells. The cytotoxic test result both of citronellol andgeraniol against murine leukemia P388 cancer cells showed that citronellol andgeraniol have cytotoxic activity against the cancer cells. To enhance the cytotoxicactivity both of the compounds, the compounds were designed into a number of estercompounds and virtual screened against the target receptor of proviral insertion sitein Moloney murine leukemia virus 1 Pim1 kinase using Molegro Virtual Docker MVD software. The virtual screening result showed that citronellol and geraniolesters have potential as anticancer and 8 ester compounds selected that are citronellylcaproate, geranyl caproate, citronellyl isobutyrate, geranyl isobutyrate, citronellyl2,2 dimethyl butyrate, geranyl 2,2 dimethyl butyrate, citronellyl caprylate and geranilcaprylate further synthesized. The synthesized ester compounds were preliminaryanalyzed by TLC, purified by column chromatography, elucidated the molecularstructure using FTIR and NMR and analyzed the mass spectra using GCMS. Toxicityanalysis of ester compounds by BSLT method showed that, citronellol and geraniolesters toxic against Artemia salina Leach shrimp larvae with LC50 values of 1.21 1.96mg mL, thereby potentially as anticancer compound. The result of in vitro cytotoxicactivity of esters against murine leukemia P388 cancer cells by MTT method showedthat, citronellol and geraniol esters cytotoxic against P388 cancer cells with IC50values of 10.63 37.69 g mL. The cytotoxic activity of citronellyl caproate thatsynthesized from caproic acid of palm kernel oil was about 4 more active thancitronellol. Ester compounds that have higher cytotoxic activity than startingcompound, then were tested for cytotoxic activity against breast MCF7 cancer cellsby alamar blue method, The result showed that citronellyl isobutyrate, citronellyl 2,2 dimethyl butyrate, geranyl isobutyrate and geranyl 2,2 dimethyl butyrate activeagainst MCF7 cancer cells with IC50 values of 1.32 4.83 g mL.
