Prediction of the binding strength of untested ligands is a central issue in structure-based drug design. In order to rapidly screen large compound databases, simple scoring schemes are often used in target-based virtual screening. The resulting scores often correlate poorly with biological affinities. More rigorous scoring methods, such as MM-PB/SA,(More)
Integrase (IN), an essential enzyme for HIV-1 replication, has been targeted in antiretroviral drug therapy. The emergence of HIV-1 variants clinically resistant to antiretroviral agents has lead to the development of alternative IN inhibitors. In the present work, binding modes of a high potent IN inhibitor, M522 and M532, within the catalytic binding site(More)
The title mol-ecule, C(28)H(20)O(8)S(2), has a T-shaped conformation. The central 9,10-anthraquinone moiety is bow-shaped with the two outer aromatic rings being inclined to one another by 13.99 (11)°. The benzenesulfonate rings are inclined to one another by 47.35 (12)°, and by 34.51 (11) and 17.88 (11)° to the bridging aromatic ring of the(More)
Based on the belief that structural optimization methods, producing structures more closely to the experimental ones, should give better, i.e. more relevant, steric fields and hence more predictive CoMFA models, comparative molecular field analyses of artemisinin derivatives were performed based on semiempirical AM1 and HF/3-21G optimized geometries.
