Terapi fotodinamik (Photodynamic Therapy/PDT) merupakan metode alternatif pengobatan kanker yang selektif. Terapi ini memerlukan fotosensitizer yang diberi penyinaran dalam lingkungan oksigen sehingga dihasilkan oksigen singlet yang mampu menghancurkan sel kanker dan merusak jaringan. Meso-tetraphenylchlorin (MTPP) dan meso-tetraphenylporphyrin (MTPC) adalah fotosensitizer yang memiliki struktur molekul yang mirip, hanya berbeda kejenuhan pada satu cincin pirolnya. MTPP adalah tetrapirol makrosiklik dengan cincin pirol tidak tereduksi sedangkan struktur MTPC tereduksi pada salah satu cincin pirolnya. Penelitian ini bertujuan untuk memprediksi hubungan antara struktur tetrapirol makrosiklik terhadap aktivitasnya secara in silico. Analisis hubungan kuantitatif-struktur aktifitas (HKSA) menggunakan serangkaian senyawa turunan porfirin dilakukan untuk memperoleh persamaan yang secara statistik memiliki kemampuan korelatif dan prediktif. Perangkat lunak Molecular Operating Environment (MOE) digunakan untuk melakukan analisis HKSA. Doking molekul dilakukan terhadap human serum albumine (HSA) danÂ peripheral benzodiazepine receptor (PBR) untuk memperoleh energi doking yang berhubungan dengan energi afinitas antara ligan dan reseptor. Simulasi doking dilakukan dengan menggunakan perangkat lunak AutoDock. Hasil menunjukkan bahwa MTPC memiliki energi doking terhadap HSA dan PBR yang paling baik. Analisis HKSA yang diperolehÂ menunjukkan bahwa MTPC lebih potensial sebagai fotosensitizer yang ditunjukkan dengan nilai IC50 yang lebih kecil.Â Kata kunci: doking molekular, fotosensitizer, HKSA, MTPC, MTPP, PDT

PDT requires a sensitizing agents and light energy, which, in the presence of oxygen, leads to the generation of singlet molecular oxygen in cell. Singlet oxygen molecules are able to kill or inhibit growth of cancer cells. Meso-tetraphenylchlorin (MTPC), a photosensitizer, is similar to meso-tetraphenylporphyrin (MTPP) but the structure has one reduced pyrrole ring. The present study aimed to develop an in silico prediction model that considers PDT activity. The Quantitative-Structure Activity Relationship (QSAR) analysis using a series of porphyrin derivatives was carried out to build a statistically significant model possessing a good correlative and predictive capability for photosensitizer in PDT. Molecular Operating Environment (MOE) software was used to performed the QSAR analysis. Docking molecule of MTPP and MTPC on human serum albumine (HSA) and peripheral benzodiazepine receptor (PBR) had been done to test the docking energy associated with binding affinity between ligand and receptor. Docking simulation was performed by AutoDock software. The results showed that MTPC had the best docking energy to HSA and PBR. Furthermore, the QSAR analysis showed that MTPC had lower IC50 value compare with MTPP. Based on QSAR and molecular docking analysis, MTPC exhibit better photosensitizer as compare with MTPP.Keywords: molecular docking, photosensitizers, QSAR, MTPC, MTPP, PDT.

Mesua ferrea L. (Ceylon ironwood, Calophyllaceae) is a popular medicinal plant with a long history in South and Southeast Asia folk medicines. In this study, we report the phytochemical analysis, FTIR fingerprint, as well as antimicrobial and antioxidant activities of the crude extract of leaves of M. ferrea and its fractions. The dried leaves of M. ferrea were extracted with ethanol by the re-maceration method. The crude extract was further partitioned in ethanol-water and ethyl acetate to obtain ethanol and ethyl acetate fractions, respectively. The identification of compounds in the extract and fractions was conducted according to the standard phytochemical screening method. Fourier-transform infrared spectroscopy (FTIR) was utilized to record their metabolites fingerprint. The antimicrobial activity was evaluated with the disk diffusion method against Escherichia coli, Bacillus subtilis, Candida albicans, and Saccharomyces cerevisiae. The antioxidant activity assay was conducted with 2,2-diphenyl-1-picrylhydrazyl (DPPH) free radical scavenging method. The crude extract of M. ferrea leaves and it fractions contained saponins, phenolic compounds, flavonoids, and terpenoids. The FTIR data supported the presence of terpenoids and glycosides in those samples as well. The extract and fractions demonstrated considerable antimicrobial activity against all tested bacteria and fungi, with MIC values ranged 3.9-31.3 μg/ml. The ethyl acetate fraction of M. ferrea leaves showed a moderate antioxidant activity with an IC50 value of 49.19 μg/ml.

The Janus tyrosine kinases (JAKs) have shown great promise as therapeutic protein targets in the treatment of cancer and inflammation diseases. This study used pharmacophore modeling to identify potential inhibitors of Janus kinase 3 (JAK3). A pharmacophore model was developed based on a known JAK3 inhibitor (1NX) and was employed to search for potential JAK3 inhibitors against Indonesian herbal compounds. Among 28 hit molecules that were identified and subjected to a molecular docking protocol against JAK3, the three compounds that had the highest affinities toward JAK3 were camelliaside B, 3-O-galloylepicatechin-(4beta-6)-epicatechin-3-O-gallate, and mesuaferrone B. These were then each subjected to a 50-ns molecular dynamics (MD) simulation. Analysis of RMSD and RMSF values indicated that the three compounds reached stability during the MD simulation. Interestingly, all three compounds had lower binding energies than 1NX against JAK3, as predicted by the MM-PBSA binding energy calculation.

In this study, we analyzed the constituents of infusion of S. polyanthum leaves and evaluated its potency as the preservative of fresh chicken meats. The infusions were prepared with the method described in Indonesian Pharmacopeia. Phytochemical content of infusion of S. polyanthum leaves was analyzed by qualitative phytochemical screening using colorimetric methods. Its application for preservative of fresh chicken meat was evaluated based on its activity in inhibiting the growth of bacteria on the meats as well as the physical observation of the preserved meats. The infusion of S. polyanthum leaves contained flavonoids, tannins, and saponins. The infusion at the optimum concentration of 10% was capable of inhibiting bacterial growth on chicken meats and extending their shelf life up to 3 days in temperature of 3-7ºC.
