The structure-inhibitory activity relationships were studied in analogous alkaloids from Picrasma quassioides and Ailanthus altissima, and their derivatives. Altogether, 53β-carboline, 18 canthinone and 7 dimeric alkaloids were tested for cyclic adenosine monophosphate (cAMP) phosphodiesterase inhibition. Major alkaloids (10, 63 and 74) among the three groups of congeners in Picrasma quassioides and Ailanthus altissima showed the most potent inhibitory activity, equal to or greater than that of papaverine used as a reference.
在来自苦木和桐树的类似生物碱及其衍生物中研究了结构-抑制活性关系。共测试了53种β-卡宾、18种卡非酮和7种二聚生物碱对环腺苷单磷酸(cAMP)磷酸二酯酶的抑制作用。在苦木和桐树的三组同源物中,主要生物碱(10、63和74)显示出最强的抑制活性,其活性等于或大于用作对照的罂粟碱。
