calcium antagonists analogous to fostedil, a series of 2-aryl- and 2-arylvinyl-substituted 1,3-henzothiazoles and 1,3-benzoxazoles bearing a phosphonate group on the phenyl ring has been synthesized by cyclization, bromination, and subsequent Michaelis-Arbuzow reaction. Pharmacological investigations on isolated organs from guinea pigs revealed both negative inotropic effects and a relaxing action on
在研究类似于ostestil的钙拮抗剂的结构-活性关系的过程中,一系列在苯环上带有膦酸酯基的2-芳基-和2-芳基乙烯基取代的1,3-苯并噻唑和1,3-苯并恶唑具有通过环化,溴化和随后的Michaelis-Arbuzow反应合成了SnO。对豚鼠离体器官的药理研究显示负性肌力作用和对平滑肌组织的松弛作用。这些活性在1,3-苯并噻唑化合物组中尤为明显。
