Human plasma protein binding (PPB) is an important pharmacokinetic property in drug design. Hologram quantitative structure-activity relationships (HQSAR) were conducted on a series of structurally diverse molecules with known PPB. The best statistical model (q = 0.72, r = 0.91) was used to predict the PPB of 62 test set compounds, and the predicted values were in good agreement with the experi...

A series of novel N'-((5-nitrofuran-2-yl/4-nitrophenyl) methylene) substituted hydrazides (3a-3i & 4a-4i) was synthesized, and tested for in vitro antimycobacterial activity, and their quantitative structure activity relationship (QSAR) of hydrazide derivatives is reported here. The results of anti-mycobacterial activity study indicated that the presence of halogen substitution at benzohydrazid...

SUMMAARY. Diuretics are an attractive class of drugs for the treatment of various disorders and in combination with some cardiovascular drugs. In the present work, 2D and 3D quantitative structure-activity relationship studies have been conducted on a series of diuretics. Significant correlation coefficients (r2 = 0.81 and q2 = 0.65, r2 = 0.91 and q2 = 0.85) were obtained, indicating potential ...

Caspase-3 inhibitory activities of some 1, 2-benzisothiazol-3-one derivatives were modeled by quantitative structure-activity relationship (QSAR) using stepwise-multiple linear regression (SW-MLR) method. The built model was robust and predictive with correlation coefficient (R(2)) of 0.91 and 0.59 for training and test groups, respectively. The quality of the model was evaluated by leave-one o...

Assessment and assurance of conformity with regulation documents assumes significant cost in modern economies. Demonstration of compliance with security standards involves providing evidence that the standards’ security criteria are met in full substantiating appropriate decision. Nevertheless despite its importance such type of activity haven't been addressed adequately by the available soluti...

An intriguing question in 3D-QSAR lies on which conformation(s) to use when generating molecular descriptors (MD) for correlation with bioactivity values. This is not a simple task because the bioactive conformation in molecule data sets is usually unknown and, therefore, optimized structures in a receptor-free environment are often used to generate the MD´s. In this case, a wrong conformationa...
