The major route of metabolism of the bis(heteroaryl)piperazine (BHAP) class of reverse transcriptase inhibitors (RTIs), atevirdine and delavirdine, is via oxidative N-dealkylation of the 3-ethyl- or 3-isopropylamino substituent on the pyridine ring. This metabolic pathway is also the predominant mode of metabolism of (alkylamino)piperidine BHAP analogs (AAP-BHAPs), compounds wherein a 4-(alkylamino)piperidine
双(杂芳基)哌嗪(BHAP)类逆转录酶抑制剂(RTIs)阿替夫定和地拉夫定的主要代谢途径是通过吡啶环上的3-乙基或3-异丙基氨基取代基的氧化N-脱烷基作用。该代谢途径也是(烷基氨基)哌啶BHAP类似物(AAP-BHAP),其中4-(烷基氨基)哌啶取代BHAP的哌嗪环的化合物的主要代谢方式。新型AAP-BHAP具有抑制非核苷逆转录酶抑制剂(NNRTI)抗性的重组HIV-1 RT和抗HIV-1 NNRTI抗性变体的能力。该报告描述了防止这种降解的方法,该方法包括用3-叔丁基氨基取代基或3-烷氧基取代基取代3-乙基-或3-异丙基氨基取代基。描述了这些类似物的合成,生物活性和代谢稳定性。大多数类似物在酶和细胞培养测定中保留抑制活性。通常,如在化合物10、20或21中,在吡啶环上的3-乙氧基或3-异丙氧基取代基导致增强的稳定性。3-叔丁基氨基取代基在AAP-BHAP系列类似物中有些益处,但在BHAP
