Description: R-82913, also known as 9-Cmbib; NSC 637653, 9-Cl-Tibo, is a RNA-directed DNA polymerase inhibitor potentially for the treatment of HIV infection. R 82913 reduce 5-HT2 receptor-mediated DOI-head-shakes in mice. R82913 inhibited the replication of thirteen different strains of HIV-1 in CEM cells with a median IC50 of 0.15 microM. R82913 was 20-fold more potent than AZT-TP in the inhibition of HIV-1 reverse transcriptase in an assay. R82913 has no effect on the replication of HIV-2 in CEM cells and does not inhibit the reverse transcriptase from this virus.
