Crystal Structures of HIV-1 Reverse Transcriptase with Etravirine (TMC125) and Rilpivirine (TMC278): Implications for Drug Design

[摘要]：Diarylpyrimidine (DAPY) non-nucleoside reverse transcriptase inhibitors (NNRTIs) have inherent flexibility, helping to maintain activity against a wide range of resistance mutations. Crystal structures were determined with wild-type and K 103N HIV-1 reverse transcriptase with etravirine (TMC125) and rilpivirine (TMC278). These structures reveal a similar binding mode for TMC125 and TMC278, whether bound to wild-type or K103N RT. Comparison to previously published structures reveals differences in binding modes for TM C125 and differences in protein conformation for TMC278.
