    • Nucleotide-competing reverse transcriptase inhibitors (NcRTI) bind to the active site of HIV reverse transcriptase (RT) in competition with the next incoming nucleotide. To further investigate the impact of RT inhibitor resistance mutations on the activity of NcRTIs, the susceptibility of > 6000 recent clinical isolates for a prototype compound, NcRTI-1, was determined. Over 80% of the profiled clinical isolates remained susceptible for NcRTI-1 (FC 1700 of these viruses showed that the combination of active site mutations M184V + Y115F correlated most with resistance to NcRTI-1 (FC = 75). Analysis also indicated that the K65R mutation is associated with hypersusceptibility to NcRTI-1 and that it reverses the reduced susceptibility caused by 20 M184V. These findings were confirmed in SDM strains. This reciprocity between the K65R and M184V mutation is unparalleled among RT inhibitors. When replicating wild-type HIV-1 in the presence of NcRTI-1, M184V + Y115F were selected. In the presence of both NcRTI-1 and tenofovir, NcRTI-1 prevents the selection of K65R.
    • 核苷酸竞争性逆转录酶抑制剂(NcRTI)与HIV逆转录酶(RT)的活性位点结合,与下一个进入的核苷酸竞争。 为了进一步研究RT抑制剂抗性突变对NcRTIs活性的影响,确定了原始化合物NcRTI-1的> 6000个近临床分离株的敏感性。 超过80%的异型临床分离物对NcRTI-1仍然敏感(FC <4)。 NcRTI-1和目前使用的RT抑制剂之间没有观察到交叉电阻,除了3TC / FTC的有限交叉电阻外。 对这些病毒> 1700的基因型的分析显示,活性位点突变M184V + Y115F的组合与NcRTI-1的抗性最相关(FC = 75)。 分析也表明,K65R突变与NcRTI-1的过度敏感性相关,并且反转了由20 M184V引起的降低的易感性。 这些发现在SDM菌株中得到证实。 K65R和M184V突变之间的这种互惠性在RT抑制剂中是无与伦比的。 在NcRTI-1存在下复制野生型HIV-1时,选择M184V + Y115F。 在NcRTI-1和替诺福韦两者的存在下,NcRTI-1阻止了K65R的选择。
