3-Nitro- and 3-cyanopyrocatechols bearing electron-withdrawing substituents at C(5) have been found to inhibit the enzyme catechol-O-methyltransferase. Structure-activity studies are discussed on the basis of the pharmocological data of 50 compounds (cf, Chapt. 4, Tables 1–7). Some 3-nitro-5-aroylpyrocatechols (Type A2, Table 1) fulfil the requirements for a clinical candidate, being orally active
已发现在C(5)处带有吸电子取代基的3-硝基和3-氰基邻苯二酚可抑制邻苯二酚-O-甲基转移酶。根据50种化合物的药理学数据讨论了结构活性研究(参见,第4章,表1-7)。一些3-硝基-5-芳酰基邻苯二酚(A 2型,表1)满足临床候选人的要求,具有口服活性,特异性,可逆性和相对短时作用。所涉及的化学工作是由描述示例性合成的选择,处理化合物来说明图9,11,14,18,22,24,25,35,41,和42 (CHAPT 5,方案1-10) 。
