描述 | Rilpivirine is a diarylpyrimidine derivative that functions as a non-nucleoside reverse transcriptase inhibitor (NNRTI) for the treatment of HIV-1 infection. It demonstrated more pronounced activity against wild-type HIV-1 (EC50 = 0.4 nM) and all single and double mutants as compared to other NNRTIs, such as nevirapine, efavirenz, TMC120, and TMC125. Rilpivirine at 1 μM showed no sign of virus breakthrough for wild-type HIV-1 within 30 days. Compared to the E-isomer of rilpivirine, the Z-isomer exhibited relatively high potency against wild-type HIV-1 with an EC50 value of 0.6 nM, but showed five times less activity against single and double mutants. Rilpivirine inhibited 81% of the 1200 recombinant clinical isolates collected from HIV-infected patients with an EC50 value less than 1 nM. The IC50 values of rilpivirine for the inhibition of CYP450 isoforms 3A4, 2C9, and 2D6 were 4.6, 5.0, and >10 μM, respectively. The pharmacokinetic studies after the i.v. administration of rilpivirine showed that the elimination half-life was 4.4 h in rat and 31h in dog. The exposure (AUCinf) were 3.1 μg h/mL (i.v. dose of 4 mg/kg) in rat, 8.7 μg h/mL (i.v. dose of 1.25 mg/kg) in dog, 1.4 μg h/mL (i.v. dose of 1.25 mg/kg) in monkey, and 44 μg h/mL (i.v. dose of 1.25 mg/kg) in rabbit. |
作用机制 | Rilpivirine is a NNRTI that shows potent activity against wild-type and mutant HIV-1 strains. The improved activity in comparison to other NNRTIs may involve a specific interaction of the cyano group in wing I with the indole ring of Trp229. |
