Integrase is one of three enzymes expressed by HIV and represents a validated target for therapy. A previous study of the diketoacid-based chemotype suggested that there are two aryl-binding domains on integrase. In this study, modifications to the indole-based diketoacid chemotype are explored. It is demonstrated that the indole group can be replaced with(More)
Integrase is one of three enzymes expressed by HIV and represents a validated target for therapy. This study reports on the discovery of a new triketoacid-based chemotype that selectively inhibits the strand transfer reaction of HIV-integrase. SAR studies showed that the template binds to integrase in a manner similar to the diketoacid-based inhibitors.(More)
Two analogues 2, 3 of (S)-alpha-methyl-3-carboxylphenylalanine 1 were synthesized to test their activity for metabotropic glutamate receptors (mGluRs). Both compounds 2 and 3 were inactive as antagonist for mGluRs, but 2 showed weak agonistic activity for GluR6 in contrast to that reported by Kemp and co-workers.
A series of new taxoids modified at the C-3', C-3'N, C-10, C-2 and C-7 positions has been designed, synthesized and evaluated for their potency to induce NO and TNF production by peritoneal murine macrophages (Mphi) from LPS-responsive C3H/HeN and LPS-hyporesponsive C3H/HeJ strains and human blood cells, and for their ability to inhibit the growth of(More)
