-C
4
alkyl;
or when the gem R
1
is —OR
3
, that R
2
may also be —C(═O)OH or a pharmaceutically acceptable ester thereof;
R
3
is independently H, or a pharmaceutically acceptable ester thereof;
R
4
is independently H or a pharmaceutically acceptable amide thereof;
R
5
and R6 are H or an amine prodrug moiety
n is 1, 2 or 3;
and pharmaceutically acceptable salts thereof;
have utility in the treatment or prophylaxis of HIV, especially reverse transcriptase mutants which allow an obligate chain terminating nucleoside- or nucleotide phosphate to be excised from the nascent DNA strand by ATP- or pyrophosphate-mediated excision.
化合物的公式为I,其中:
R1独立地为H、—OR3、—NHR4;C1-C4烷基;或当n为2时,相邻的R1共同定义一个烯烃键;
R2为H;或当gem R1为C1-C4烷基时,R2也可以是C1-C4烷基;或当gem R1为—OR3时,R2也可以是—C(═O)OH或其药学上可接受的酯;
R3独立地为H或其药学上可接受的酯;
R4独立地为H或其药学上可接受的酰胺;
R5和R6为H或一种胺前药物基团;
n为1、2或3;
以及其药学上可接受的盐;
在治疗或预防HIV方面有用,特别是逆转录酶突变体,其允许ATP或焦磷酸介导的切除将一个必需的链终止核苷酸或核苷酸磷酸从新生DNA链中切除。
