The ginkgolides represent a challenge for the organic chemist owing to their unique cage structure and their high potential biological activity. They were found to be potential PAF antagonists. The results of studies carried out in our laboratory are discussed, leading to conclusions on ginkgolides quantitative structure±activity relationship by using CoMFA and the probable pharmacophore and th...

The aim of this study is to enhance the predictivity power of CoMFA and CoMSIA models by means of different variable selection algorithms. The genetic algorithm (GA), successive projection algorithm (SPA), stepwise multiple linear regression (SW-MLR), and the enhanced replacement method (ERM) were used and tested as variable selection algorithms. Then, the selected variables were used to genera...

Three-dimensional quantitative structure activity relationship (3D QSAR) analysis was carried out on a et of 56 N,N'-diarylsquaramides, N,N'-diarylureas and diaminocyclobutenediones in order to understand their antagonistic activities against CXCR2. The studies included comparative molecular field analysis (CoMFA) and comparative molecular similarity indices analysis (CoMSIA). Models with good ...

Dihydrofolate reductase is known for important role in cancer and microbial diseases and hence is considered as validated target for aforementioned diseases. Three dimensional quantitative structure activity relationship studies (3D-QSAR) involving comparative molecular field analysis (CoMFA) and comparative similarity indices analysis (CoMSIA) were performed using twenty two Pneumocystis carin...
