clearly seen to correlate with the inhibitory activity observed. The chemical syntheses of the new 3-phenyl- and 3-substituted phenylpyrazolo[1,5-a]pyrimidines with various substituents are reported. The syntheses of various 8-phenyl-2-substituted pyrazolo-[1,5-a]-s-triazines, certain s-triazolo[1,5-a]-s-triazines and s-triazolo[1,5-a]pyrimidine derivatives prepared in connection with the present study are
已经制备了许多新的次黄嘌呤类似物作为黄嘌呤氧化酶的底物抑制剂。最值得一提的抑制新次黄嘌呤类似物是3-(米间-甲苯基)吡唑并[1,5-一个]嘧啶-7-酮(47),ID 50 0.06μ中号和3-苯基吡唑并[1,5-一个]嘧啶-7- -酮(46),ID 50 0.40μ M. 5-(p -氯苯基)吡唑并[1,5-一个]嘧啶-7-酮(63)和相应的5-硝基苯基衍生物64表现出ID 50的0.21及0.23μ中号, 分别。7-苯基吡并[1,5一] -小号-三嗪-4-酮(40)被示出为表现出ID 50 0.047μ M.这些新的苯基取代的次黄嘌呤类似物的结构-活性关系进行了讨论,并与比较黄嘌呤类似物3-米甲苯基-和3-苯基-7-羟基[1,5-一个]嘧啶-5-酮(90)和(91),预先从我们的实验室报道具有ID 50 0.025 0.038和μ中号, 分别。苯基和取代的苯基的存在直接有助于这些有效抑制
