Dibenz[b,f][1,4]oxazepin-11(10H)-ones (III), pyrido[2,3-b][1,4]benzoxazepin-6(5H)-ones (IV), and pyrido[2,3-b]- [1,5]benzoxazepin-5(6H)-ones (V) were found to inhibit human immunodeficiency virus type 1 reverse transcriptase with IC50 values as low as 19 nM. A-ring substitution has a profound effect on activity, with appropriate substituents at the positions ortho and para to the lactam nitrogen providing
Dibenz [b,f] [1,4] oxazepin-11(10H)-ones(III),吡啶基[2,3-b] [1,4] benzoxazepin-6(5H)-ones(IV)和pyrido发现[2,3-b]-[1,5]苯并x庚因-5(6H)-ones(V)抑制人免疫缺陷病毒1型逆转录酶,IC50值低至19 nM。A-环取代对活性具有深远的影响,内酰胺氮邻位和对位的适当取代基可显着增强效能。C形环的替代通常对活性是中性的或有害的。尽管通常在内酰胺羰基间位的C-环氨基取代基对活性是有益的,但是当A-环被最佳取代时,它基本上没有作用。像双吡啶二氮杂酮尼维拉平一样,化合物III-V对HIV-1 RT具有特异性,
