Various embodiments described herein are directed to compounds of formula (I), (II), (III) or (IV) for use as potent inhibitors of HIV integrase and for treatment of patients afflicted with AIDS. A major challenge of human immunodeficiency virus (HIV) chemotherapy continues to be the inevitable selection of resistance by the virus towards known drug regimens. Treating resistant HIV strains calls for novel antivirals with unique structural cores. Some embodiments are directed to compounds featuring a 3-hydroxypyrimidine-2,4-dione-5-carboxamide core that consistently confers low nanomolar potencies against HIV-1 in cell culture. Biochemical testing and molecular modeling results corroborate an antiviral mechanism of action of inhibiting integrase strand transfer (INST). Preliminary testing against raltegravir-resistant HIVs showed marginal cross resistance, suggesting that the chemotypes of the various embodiments described herein could fit an inhibitory profile of second generation INSTIs.
本文描述的各种实施例涉及公式(I)、(II)、(III)或(IV)的化合物,用作HIV整合酶的有效
抑制剂,并用于治疗患有艾滋病的患者。人类免疫缺陷病毒(HIV)化疗的一个主要挑战仍然是病毒对已知药物方案的抗药性的不可避免选择。治疗耐药HIV毒株需要具有独特结构核心的新型抗病毒药物。一些实施例涉及具有3-
羟基嘧啶-2,4-二酮-5-羧酰胺核心的化合物,在
细胞培养中始终表现出对HIV-1的低纳摩尔潜力。生化测试和分子建模结果证实了一种抗病毒作用机制,即抑制整合酶链转移(INST)。对抗拉替尼耐药HIV的初步测试显示了边缘性交叉耐药性,表明本文描述的各种实施例的化合物类型可能符合第二代INSTI的抑制特性。
