between d4T monophosphate and the known NNRTI MKC-442, which were linked through a labile p-hydroxybenzoyl protection group in the N-3 position of MKC-442. Double-prodrugs 2 and 3 were conjugates between d4T monophosphate and the new NNRTIs 15 and 19 linked through a stable phenolic linker that was a part of the N-1 substituents of the NNRTIs. The double-prodrugs 1, 2, and 3 all had good activities against
本文报道了基于已知的混合SATE(S-酰基-2-硫代乙基)前药方法的新型双重前药对HIV的合成和抗病毒活性。核苷逆转录酶抑制剂(NRTI)d4T的单磷酸酯被一个SATE基团和一个芳香基团掩盖,通过该基团连接了一个非核苷逆转录酶抑制剂(NNRTI)。双前药1是d4T单磷酸酯与已知的NNRTI MKC-442的混合物,后者通过MKC-442的N-3位上不稳定的对羟基苯甲酰基保护基连接。双前药2和3是d4T单磷酸酯与新的NNRTI 15和19之间的结合物,新NNRTI 15和19通过稳定的酚类连接基连接,该连接基是NNRTIs N-1取代基的一部分。双前药1、2和3对野生型HIV-1,Y181C突变体均具有良好的活性,
