ABSTRACT
(
S
)-9-[3-Hydroxy-2-(phosphonomethoxy)propyl]adenine [(
S
)-HPMPA], is an effective broad-spectrum antiviral against many DNA viruses but has been reported to be inactive against human immunodeficiency virus (HIV). We synthesized several alkoxyalkyl esters of (
S
)-HPMPA and now report that hexadecyloxypropyl-(
S
)-HPMPA [HDP-(
S
)-HPMPA] and octadecyloxyethyl-(
S
)-HPMPA [ODE-(
S
)-HPMPA]had 50% effective concentrations of 0.4 to 7.0 nanomolar and were nearly fully active against HIV variants having reverse transcriptase mutations M184V and K103N and against a zidovudine-resistant variant with mutations D67N, K70R, T215Y, and K219Q. Resistance to HDP-(
S
)-HPMPA and ODE-(
S
)-HPMPA was noted for a mutant with mutation K65R. HDP-(
S
)-HPMPA is also active against herpes simplex virus type 1, human cytomegalovirus, hepatitis B virus, adenoviruses, and orthopoxviruses and is worthy of further evaluation as a possibly therapy for HIV infection.
摘要
(
S
)-9-[3-羟基-2-(磷酰甲氧基)丙基]腺嘌呤[(
S
)-HPMPA]是一种对多种 DNA 病毒有效的广谱抗病毒药物,但据报道对人类免疫缺陷病毒(HIV)无效。我们合成了几种(S)-HPMPA 的烷氧基烷基酯。
S

S
)-HPMPA[HDP-(
S
)-HPMPA]和十八烷氧基乙基-(
S
)-HPMPA[ODE-(
S
)-HPMPA]的50%有效浓度为0.4至7.0纳摩尔,对具有逆转录酶突变M184V和K103N的HIV变体以及具有突变D67N、K70R、T215Y和K219Q的齐多夫定耐药变体几乎完全有效。对 HDP-(

S
)-HPMPA的耐药性。HDP-(
S
)-HPMPA对 1 型单纯疱疹病毒、人类巨细胞病毒、乙型肝炎病毒、腺病毒和正疱疹病毒也有活性,值得作为一种可能的艾滋病病毒感染疗法进行进一步评估。
