Combinatorial Chemistry & High Throughput Screening - Volume 20, Issue 1, 2017

Aim and Objective: Actinomycetes produce structurally unique secondary metabolites with pharmaceutically essential bioactivities. Salinispora, an obligate marine actinomycete, produces structurally varied and unique secondary metabolites. There is plenty of scope for development of drugs from the novel compounds isolated from Salinispora. Anticancer, antibacterial and anti-protozoa activities have been shown for Salinosp Read More

Background: Current drugs available for the treatment of Chagas disease are fraught with several challenges including severe toxicity and limited efficacy. These factors coupled with the absence of effective drugs for treating the chronic stage of the disease have rendered the development of new drugs against Chagas disease a priority. Objective: This study screened several imidazole-based compounds for anti-Trypanosoma p Read More

Aim and Objective: This study investigates molecular structural requirements that are responsible for the antioxidant activity in phenolic compounds. Method: Antioxidant activity of compounds was determined with a 2,2-diphenyl-1-picrylhydrazyl (DPPH) free radical assay. Principal component analysis (PCA) was used to classify phenolic antioxidants according to the key molecular features that contribute to their anti Read More

Aim and Objective: Thiazol-2-imine derivatives are interested for their pharmaceutical and biologic activities. A literature survey reveals that there have been no any reports on the synthesis of thiazol-2-imine derivatives without substituents in position C-4 and C-5 via one-pot reaction. Herein we report an efficient one-pot route for synthesis of these compounds in good to high yields. Materials and Method: To a stirred mixture of a Read More

Objective: Support Vector Regression (SVR) has become increasingly popular in cheminformatics modeling. As a result, SVR-based machine learning algorithms, including Fuzzy-SVR and Least Square-SVR (LS-SVR) have been developed and applied in various research areas. However, at present, few downloadable packages or public-domain software are available for these algorithms. To address this need, we developed t Read More

Aim and Objective: Surface Plasmon Resonance (SPR) based biosensor system was developed for the detection of Delta F508 (ΔF508del) Cystic Fibrosis (CF) mutation in both synthetic and real samples. Material and Method: In order to provide an effective hybridization between probe and the Polymerase Chain Reaction (PCR) amplicons (target), streptavidin was bound to the surface and biotin-tag probe was sent to the stre Read More

Aim and Objective: This study introduces a green and effective approach for the preparation of biologically-active heterocyclic compounds including 2-amino-5,10-dihydro-5,10-dioxo-4Hbenzo[ g]chromenes and tetrahydrobenzo[g]quinoline-5,10-diones using one-pot multi-component reactions in the presence of Fe3O4@SiO2-NH2 nanocomposite. The preparation and use of aminofunctionalized Fe3O4@SiO2 as a powerful and reu Read More

Objective: A simple and efficient procedure is achieved for the synthesis of indole-2-one derivatives via three-component reaction of N-alkylisatin, activated acetylenic compounds and alkyl bromide in the presence of triphenylphosphine in water under two conditions; room temperature and microwave irradiation. Materials and Methods: All chemicals used in this work were prepared from Fluka (Buchs, Switzerland) and were Read More

Background: Hormone based birth control often causes various side effects. A recent study revealed that temporary infertility without changing hormone levels can be attained by inhibiting Katanin p60 ATPase-containing subunit A-like 1 protein (KATNAL1) which is critical for sperm maturation in the testes. Objective: This study aimed at attaining the most energetically stable three dimensional (3D) structure of KATN Read More
