benzylindoldiketo acid (CHI-1043) acting as HIV-1integrase strand transfer inhibitor. We herein report the synthesis of new structurally different compounds in which the 1,3-diketo acid moiety has been substituted with other functionalities. The synthesized derivatives were evaluated for their activity on the IN enzyme and in MT-4 cells but only 4-[l-(4-fluorobenzyl)-4-methoxy-1H-indol-3-yl)-3-hydroxyfuran-2(5H)-one
We report herein the development of a new three-dimensional pharmacophore model for HIV-1 integrase inhibitors which led to the discovery of some 4-[1-(4-fluorobenzyl)-1H-indol-3-yl]-2-hydroxy-4-oxobut-2-enoic acids that are able to specifically inhibit the strand transfer step of integration at nanomolar concentration. The synthesis of the new designed molecules is also described. (c) 2008 Elsevier Ltd. All rights reserved.
