摘要 设计并合成了一个香豆素及其补骨脂素类似物EMAC10157a-bdg和EMAC10160a-bdg的小型文库,以研究结构修饰对其抑制能力和对碳酸酐酶同工型 I、II、IX 和 XII 的选择性分布的影响。没有一种新化合物表现出对 hCA I 和 II 同工酶的活性。相反,香豆素和补骨脂素衍生物在低微摩尔或纳摩尔浓度范围内对肿瘤相关异构体 IX 和 XII 具有活性。这些数据进一步证实了我们之前对类似衍生物的发现,证实香豆素和补骨脂素都是设计同工酶选择性 hCA 抑制剂的有趣支架。

Compounds of the Formula I: ##STR1## and pharmaceutically acceptable salts thereof are leukotriene antagonists. These compounds inhibit SRS-A and leukotriene synthesis and are antagonists of SRS-A and are thus useful in the treatment of asthma, allergic disorders, inflammation, skin diseases and certain cardiovascular disorders.

Compounds of the formula I:
and their pharmaceutically acceptable salts are leukotriene antagonists. These compounds inhibit SRS-A and leukotriene synthesis and are antagonists of SRS-A and are thus useful in the treatment of asthma, allergic disorders, inflammation, skin diseases and certain cardiovascular disorders. For this purpose they are made into pharmaceutical composition.
In the formula, and B are hydrogen or certain rings, X is O, S, SO, or SO2; Y is H, OH, =0, or OR2; n is 0,1 or 2;a,b and c are 0 to 5; R' is one of CH2OH, CHO, tetrazolyl, CN, certain phenolic heterocycles, certain esterfied carboxyls, hydroxymethyl ketone, and certain substituted carbamoyl and sul- fonylamino groups: and R2 and R' are H oralkyl orform a ring.
