Our previous studies led to discovery of a very potent benzylindoldiketo acid (CHI-1043) acting as HIV-1 integrase 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 (12) was able to strongly inhibit HIV-1 probably by biotransformation into CHI-1043.

Abstract
Our previous studies led to discovery of a very potent benzylindoldiketo acid (CHI-1043) acting as HIV-1 integrase 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 (12) was able to strongly inhibit HIV-1 probably by biotransformation into CHI-1043.File in questo prodotto:
