Unexpected Binding Mode of a Cyclic Sulfamide HIV-1 Protease Inhibitor

Unexpected Binding Mode of a Cyclic Sulfamide HIV-1 Protease Inhibitor. Baeckbro, Kristina; Loewgren, Seved; Oesterlund, Katrin; Atepo, Johnson; Unge, Torsten; Hulten, Johan; Bonham, Nicholas M.; Schaal, Wesley; Karlen, Anders; Hallberg, Anders (Department of Molecular Biology Biomedical Centre, Uppsala University, Uppsala SE-751 24, Swed.). Journal of Medicinal Chemistry, 40(6), 898-902 (English) 1997 American Chemical Society. CODEN: JMCMAR. ISSN: 0022-2623. DOCUMENT TYPE: Journal CA Section: 1 (Pharmacology) Section cross-reference(s): 75 Two cyclic, C2-sym. HIV-1 protease inhibitors, one sulfamide and one urea deriv., both comprising Ph ether groups in the P1/P1' positions, were cocrystd. with HIV-1 protease, and the crystal structures were detd. to 2.0 ? resoln. The structure of the urea showed a conformation similar to that reported for a related urea by Lam et al., while the sulfamide adopted an unanticipated conformation in which the P1' and P2' side chains were transposed. 185449-94-9 and 185449-98-3 are just another two chemicals used in this study. .
