A series of 10 novel analogues of fluphenazine (FPh) were synthesized. Influence of the synthesized analogues of FPh on frequency of apoptosis and necrosis in cultures of human lymphocytes genotoxically damaged in vitro with benzo[a]pyrene (B[a]P; 7,5 microM, 48 h) was compared with the effect of FPh. Activity of the tested compounds was expressed by ED50 (pro-apoptotic activity) and TD50 (pro-...

Over the last 20 years, extensive QSAR studies establish an attractive approach to the elucidation of the modern drug chemistry. In the recent years, constant increase in the performance of hardware and software transformed quantitative structure activity relationship (QSAR) and quantitative structure property relationship (QSPR) into powerful and widely used model for the prediction of many bi...

A compound 2-(anilino)-1-(4-phenylphenyl)ethanone was synthesized by reaction between biphenyl acid chloride and aniline. The synthesized compound was screened for analgesic activity. The selection of the compound was on the basis of QSAR study performed on the biphenyl analogs having anti-inflammatory activity. 2D QSAR study using topological descriptors revealed the important features require...

Glycogen synthase kinase-3 beta (GSK-3β) is implicated in abnormal hyperphosphorylation of the tau protein and its inhibitors may be a promising therapeutic approach for treating Alzheimer’s disease. Here, series C-glycosylfavone derivatives as GSK-3β was selected to perform two-dimensional quantitative structure activity relationship (2D-QSAR) method docking analysis. The 2D-QSAR model generat...

Rho Kinase (ROCKII) has been recently implicated in several cardiovascular diseases prompting several attempts to discover and optimize new ROCKII inhibitors. Towards this end we explored the pharmacophoric space of 138 ROCKII inhibitors to identify high quality pharmacophores. The pharmacophoric models were subsequently allowed to compete within quantitative structure-activity relationship (QS...

A number of binary QSAR models have been developed using methods of artificial neural networks, k-nearest neighbors, linear discriminative analysis, and multiple linear regression and have been compared for their ability to recognize five types of chemical compounds that include conventional drugs, inactive druglikes, antimicrobial substituents, and bacterial and human metabolites. Thus, 20 bin...

The use of quantitative structure–activity relationships, since its advent, has becomeincreasingly helpful in understanding many aspects of biochemical interactions in drug research.This approach was utilized to explain the relationship of structure with biological activity ofantibacterial. For the development of new fungicides against, the quantitative structural–activityrelationship (QSAR) an...

Cyclophilin D (CypD) is a peptidyl prolyl isomerase F that resides in the mitochondrial matrix and associates with the inner mitochondrial membrane during the mitochondrial membrane permeability transition. CypD plays a central role in opening the mitochondrial membrane permeability transition pore (mPTP) leading to cell death and has been linked to Alzheimer's disease (AD). Because CypD intera...
