Adrenergic Beta-2 Receptor (ADRB2) is a member of G-protein coupled receptors family, which has served as targets for more than 30% of top-selling drugs in the market. Recently, an enhanced dataset of ligands and decoys for ADRB2 has publicly available. However, the original retrospective structure-based virtual screening campaign accompanying the dataset showed relatively poor quality with enrichment factor of true positives at 1% false positives (EF1%)value of 3.9. In this article, the construction and retrospective validation of a structure-based virtual screening protocol by employing PLANTS1.2 as the molecular docking software and PyPLIF as an alternative post docking scoring functions are presented. The results show that the developed protocols have better quality compared the original structure-based virtual screening with EF1% values of 24.24 and 8.22 by using ChemPLP from PLANTS1.2 and by using Tc-PLIF from PyPLIF, respectively. Further investigation by performing systematic filtering resulted in the identification of D113, S203, and N293 as molecular determinants in ADRB2-ligand binding.Key words: Structure-based virtual screening, molecular docking, adrenergic beta-2 receptor, protein-ligand interaction fingerprinting, molecular determinants

Publisher : Faculty of Pharmacy Universitas Gadjah Mada, Yogyakarta, Skip Utara, 55281, Indonesia

Dead time that defined as a retention time of unretained substance in the chromatographic coloumn, is needed to determine all retention parameters in coloumn chromatography such as corrected retention time, relative retention time and Kovats Retention Indices.This research reported a comparison between the iteration and linearization of corrected retention times of homologous series such as n-alkane, akylrylketone, alkylbenzene and 2-alkanone. Furthermore the iteration method provides better dead-time values and smaller standard deviations than the linearization method. Moreover, the dead-time calculation obtained according to homologous series is not depending on solvent composition for various homologous series.The n-alkane homologous series show better indication accuracy of fit (S/N) in comparison with other homologous series, thereafter 2-alkanone exhibit the second best adjustment.Keywords: Dead-time evaluation, homologous series, methanol/water solvent, RP-HPLC.

Viteosin-A, a tracheospasmolytic compound, was successfully isolated from n-hexane extract of the leaves of Vitex trifolia L. With the concentration of 0.05 and 0.15 mg/ml viteosin-A inhibited a guinea pig tracheal contraction due to histamine (10-7 â€“ 10-3 M) in vitro by 27.1 and 47.9 %, respectively. Confirmation of C-5 and C-6 configuration is necessary to determine the active reaction site of viteosin-A and its receptor for future development. This research was focused on a molecular modeling of viteosin-A using computational method with HyperChem Pro 4.0 for Windows as software. Based on spectroscopic data and molecular modeling, viteosin-A has S configuration at C-5 and C-6, and therefore was confirmed as (5S,10S)-6S-acetoxy-8R-methyl-9ï¡-hidroxy-labda-13Z-en-16,15-olide.Keywords: viteosin-A, molecular modeling

In order to generate potent C-9154 antibiotic derivatives, it has been conducted the synthesis and antibacterial activity evaluation of p-anisyl ethyl fumarate and ethyl N-phenyl fumaramate. These target molecules were chosen as the former would be a para-methoxy substituted C-9154 derivative, whereas the latter would be an example of unsubstituted C-9154 derivative bearing an amido-ester fumaric side chain.p-Anisyl ethyl fumarate was synthesized from p-anisaldehyde by reduction with NaBH4, condensation of p-anisyl alcohol with maleic anhydride, and esterification of the resulting p-anisyl maleic acid with ethanol in the presence of benzenesulfonic acid as the catalyst. These reactions gave satisfactorily yields (55-81 %) in all steps involved. In the case of ethyl Nphenyl fumaramate, this molecule was synthesized in 84 % yield through condensation of aniline with maleic anhydride, followed by esterification with ethanol in the presence of concentrated sulfuric acid.The antibacterial activity test showed that the minimum inhibition concentration (MIC) of p-anisyl ethyl fumarate and ethyl N-phenyl fumaramate towards Staphyllococcus aureus were 15 and 25 Î¼g/mL. Interestingly, the MIC values of these two compounds towards Eschericia coliwere also 15 and 25 Î¼g/mL respectively. Thus, the data showed that the two C-9154 derivatives obtained are sufficiently potent and possess antibacterial activities which are comparable to the antibacterial activity of C-9154 itself towards Staphyllococcus aureus (12.5 â€“ 37.5 Î¼g/mL) and Eschericia coli (25 â€“ 50 Î¼g/mL).Key words: synthesis, antibacterial activity, fumarate and fumaramate.

Breast cancer is the most common cancer occurring in women after cervix cancer in Indonesia. Tumor metastasis is the major cause of mortality in breast cancer. For a tumor cell to metastasize effectively, it must induce angiogenesis. 17 β-estradiol has been shown to stimulate the proliferation and angiogenesis of breast cancer cells which express estrogen receptor (ER), T47D (human breast cancer cell line). In the present study Pentagamavunon-1 or PGV-1 [2,5-bis-(4’-hydroxy-3’,5’-dimethylbenzylidene)-cyclopentanone], an analogue of curcumin [1,7-bis-(4’-hydroxy-3’-methoxyphenyl)-1,6-heptadiena-3,5-dion], were tested on their cytotoxicity and suppression effect on angiogenic factors (i.e. VEGF and COX-2) on the breast cancer cell lines (T47D) induced by 17 β-estradiol 10-8 M. The results showed that PGV-1 performed cytotoxicity effect againts T47D cells with IC50 values 3,16 μM. This was more potent than curcumin (IC50 = 19,05 μM). PGV-1 5 μM and curcumin 20 μM decrease VEGF and COX-2 expression. These results suggest both compounds possessed antiangio-genic potensial.Key words : PGV-1, curcumin, 17 β-estradiol, angiogenesis
