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

Silver nanoparticles were successfully synthesized with chitosan hydrolysate as stabilizing agent at room temperature. Silver nitrate, glucose and sodium hydroxide were used as silver precursor, reducing agent and accelerator respectively. Chitosan hydrolysate was produced by enzymatic process with papain enzyme. Molecular weight of chitosan hydrolysate determined by viscosimetry methode based on Mark-Howink equation. The effect of molecular weight of chitosan hydrolysate as stabilizing agent and AgNO3 concentration toward surface plasmon resonance (SPR) of silver nanoparticle was investigated. It is also reported the antibacterial activity of silver-chitosan nanocomposites against Staphylococcus aureus and Escherichia coli. The products of silver nanoparticles were characterized by UV-Vis spectroscopy and transmission electron microscopy (TEM). The result showed that the formation of silver nanoparticles was shown by the appearance of surface plasmon resonance (SPR) at 403–421nm from the corresponding UV-Vis spectra. The molecular weight of chitosan hydrolysate affects the absorbance intensity and the wavelength of SPR. Silver nanoparticles were spherical in shape as identified by TEM images with size in range of 4–26nm. The silver nanoparticles have showed high antibacterial activity against Escherichia coli and Staphylococcus aureus.Key word: green synthesis, silver nanoparticles, chitosan hydrolysate, stabilizing agent, antibacterial activity

The object of the present study was to develop a simple, precise simultaneous HPLC method for estimation of Tamsulosin (TAM) and Finasteride (FIN) in bulk and pharmaceutical dosage form. The method involves the use of easily available inexpensive laboratory solvents. The separation was achieved on spherisorb C-18 column with isocratic flow detected at 210nm. The mobile phase consisted of methanol: 0.03mM phosphate buffer pH 3.5 (70:30v/v) with flow rate of 1.0mL/min. A linear response was observed over concentration range of 4-40μg/mL for tamsulosin and 10-80μg/mL for finasteride. Limit of detection and limit of quantitation for tamsulosin were 1.13μg/mL and 3.43μg/mL, and for finasteride were 1.37μg/mL and 4.21μg/mL, respectively. The recovery of tamsulosin and finasteride was found to be in the range of 98.80-100.24% and 99.33-100.33%,respectively. The low %RSD value indicated a good precision and stability of the analytical method. The analysis concluded that the method was selective for simultaneous estimation of tamsulosin and finasteride can be potentially used for the estimation of these drugs in combined dosage form.Key words: HPLC, tamsulosin, finasteride, validation, pharmaceutical dosage form

Non steroidal Anti- inflammatory drugs have their origin as the derivatives of plants, which were observed to have their therapeutic effects in different disease states. They have the advantage of local action without developing central adverse effects and cognitive impairments. Side effects have been well described, although partly neglected. Topical delivery of NSAID has its therapeutic applications in management of pain and inflammation in Rheumatoid arthritis patients. Rheumatoid arthritis is a chronic systemic inflammatory disorder that may affect many tissues and organs but principally attacks the synovial joints. It can be disabling and painful condition, which can lead to substantial loss of functioning and mobility if not adequately treated. The aim of the present investigation was to compare the Ketoprofen cream with Diclofenac and Piroxicam cream in a group of volunteers suffered from Rheumatoid arthritis and to compare the efficacy of these creams in reduction of inflammation. This single blind comparative study was done to determine the efficacy, tolerability and acceptability of topical application of Ketoprofen cream (1%w/w) vs diclofenac cream (1%w/w) and piroxicam cream (0.5%w/w) in Rheumatoid arthritis patients. In this study, one hundred and twenty five volunteers suffering with acute Rheumatoid arthritis and age group between 40-70 years were analyzed for assessing the intensity of pain and anti-inflammatory effects of these three creams. The study revealed that Ketoprofen cream provides a good level of pain relief removes swelling and tenderness and improves the functional impairment, without the systemic adverse events associated with oral NSAIDs.Key Words: Cream, Diclofenac, Ketoprofen, Piroxicam, Rheumatoid arthritis

Porphyrin derivatives are potential compounds for diagnostic agent and photosensitizer in photodynamic therapy. However, they have a weakness in molar absorptivity, especially in visible region of Q band which used to excite them. Due to incapabilities of porphyrin, other tetrapyrole derivatives, such as chlorophyllin can be alternative for a lead compound of photosensitizer. In the present research, two chlorin derivatives were isolated from commercial chlorophyllin product. Their photophysical and physicochemical properties, i.e. molar absorptivity, quantum yield of fluorescence and quantum yield of singlet oxygen were determined. Chlorophyllin carboxylic acid form, Cu(II)-chlorin e4 and Cu(II)-chlorin e6,were successfully isolated with recovery of 11.33% and 16.46%, respectively. The absorption spectrum of Cu(II)-chlorin e4 showed an intense Soret band at 406 nm and two weaker Q bands at 628nm, 658nm. Fluorescence efficiency was 0.09 while efficiency for singlet oxygen at pH 6.3 and 7.4 were 0.0052±0.0017 and 0.0066±0.0012. Cu(II)-chlorin e6 displayed soret band at 407nm and Q bands at 627nm, 663nm. Singlet oxygen at pH 6.3 was 0.0029±0.0007, while at pH 7.4 was 0.0034±0.0001. However, Cu(II)-chlorin e6 did not show fluorescence.Key words: Chlorophyllin, Cu(II)-chlorin e4, Cu(II)-chlorin e6, singlet oxygen fluorescence

Cytochrome P450 2A6 (CYP2A6) is the principal enzyme involved in the metabolic activation of tobacco-specific nitrosamines to their ultimate carcinogenic forms and metabolism of nicotine. The present study was developed to investigate the genetic polymorphism of CYP2A6 in Javanese Indonesian subjects carrying the CYP2A6*1 allele and the CYP2A6*4. The whole gene deletion of CYP2A6 (CYP2A6*4) may inhibit smokers from giving up smoking, but appears to function as a protective factor against to some cancer. However, the investigation of these allele, a major functional polymorphisms common in Asian populations, have not been reported among Javanese Indonesian population. A single polymerase chain reaction-restriction fragment length polymorphism was used to resolve the genotypes into CYP2A6*1 (wild type) and CYP2A6*4 (CYP2A6del). The sample studied consisted of 100 healthy subject that consist of 50 non smokers and 50 smoker from Javanese Indonesian population. The allele frequencies of *1 (wild type) and *4, were 47.5 and 52.5%, respectively. When the two allel were considered simultaneously, among the non-smokers, 45% were genotyped for CYP2A6*1/*4 and 5% were genotyped for CYP2A6*4/*4; on the other hand all of the smoker were genotyped for CYP2A6*1/*4 and there was no homozygote of wild type. Based on the data collected, it could be concluded that the polymorphism of CYP2A6 were detected in among Javanese population sample study and the allele frequencies of CYP2A6*4 were high.Key word: Polymorphism, CYP2A6*1, CYP2A6*4, Javanese Indonesian
