RESUMO

A series of highly potent, structurally novel, non-nucleoside RT inhibitors has been described. Low nanomolar concentrations of 5-chloro-3-(phenylsulfonyl)-indole-2-carboxamide (1) inhibit the HIV-1 RT enzyme in vitro and HTLVIIIb viral spread in MT-4 human T-lymphoid cells. Good oral bioavailability was observed in rhesus monkeys upon oral dosing of 1 as a suspension in methocel. When compared to other non-nucleoside inhibitors (e.g. 15-18), 1 possesses improved inhibitory potency with respect to the wild-type RT, as well as the K103N and Y181C mutant enzymes. Additional studies within this class of inhibitors are in progress.

RESUMO

In an ongoing effort to develop novel nonnucleoside, specific human immunodeficiency virus type 1 (HIV-1) reverse transcriptase (RT) inhibitors, a series of 3-[(pyridylmethyl)amino]- and 3-[(phenylmethyl)amino]-2-pyridinone derivatives was synthesized and tested for HIV-1 RT inhibitory activity. The more potent compounds have a 2'-methoxy group and 4'- and/or 5'-aliphatic substituents on the pyridyl and phenyl rings. Several of the more potent compounds were also evaluated for antiviral activity in MT-4 cell culture. From this series of compounds, 3-[N-[(5-ethyl-2-methoxy-6-methyl-3-pyridyl)methyl]amino]-5-ethyl-6- methylpyridin-2(1H)-one (6) was selected for clinical evaluation.

RESUMO

Imidazolemethyl diaryl ethers are potent inhibitors of farnesyl-protein transferase. The SNAr displacement reaction used to prepare these diaryl ethers was amenable to rapid parallel synthesis of FPTase inhibitors. The use of a broad range of commercially available phenols quickly identified compounds which proved active in cells.
