irreversibly binding to the enzyme. Several 6-(alkylamino)uracils were weak inhibitors of DNA polymerases III; the optimum alkyl groups for enzyme binding were n-pentyl and n-hexyl, which apparently can occupy the planar enzyme binding site. The varied activities of 6-anilinouracils on a mutant DNA polymerase, resistant to 6-(phenylhydrazino)- and 6-(benzylamino)uracils bearing a p-OH or NH2 group, have altered
发现取代的6-茴香胺嘧啶是来自枯草芽孢杆菌的复制特异性酶DNA聚合酶III的有效抑制剂。通过在苯环的间位和对位包含小烷基或卤素,可以最大程度地发挥抑制作用。极性取代基大大降低了活性。定性结构-活性关系表明,该元位置可以耐受较大的基团,这表明该位置可能适合引入能够不可逆地结合酶的基团。几种6-(烷基氨基)尿嘧啶是DNA聚合酶III的弱抑制剂。用于酶结合的最佳烷基是正戊基和正己基,它们显然可以占据平面酶结合位点。6-苯胺嘧啶对突变型DNA聚合酶的各种活性,
