produce antiprotozoal activity without significant toxic effects on mammalian hosts prompted syntheses of 1-substituted hypoxanthines bearing functionalized side chains whose groupings might interact with appropriate groupings of HGPRT to form covalent bonds or strong hydrophobic bonds. 3-(Fluorosulfonyl)benzoyl, 4-(fluorosulfonyl)benzoyl, 4-chlorobenzoyl, and bromacetyl derivatives of two parent amines
有证据表明,体内有效抑制次黄嘌呤-鸟嘌呤磷酸核糖基转移酶(HGPRT,EC 2.4.2.8)应产生抗原生动物活性,而对哺乳动物宿主无明显毒性作用,提示合成带有功能侧链的1-取代的次黄嘌呤,其侧基可能与适当的亚基相互作用。 HGPRT形成共价键或强疏水键。为了评估在这种联系。这些化合物均不能延长感染伯氏疟原虫的小鼠的寿命,也不能显示出H.Ep.-2细胞对HGPRT有明显的体外抑制作用,
