Novel antiasthmatic agents with dual activities of thromboxane A2 synthetase inhibition and bronchodilation. III. 4-[2-(5-ethyl-2-thienyl)]-2'-[2-(1-imidazolyl)ethyl]-1(2H)- phthalazinones.
Synthesis and pharmacological evaluation of novel 4-[2-(5-ethyl-2-thienyl)]-2-[2-(1-imidazolyl)ethyl]-1(2H)-phthalazinone s are described. The phenyl moiety of the phthalazinone skeleton was found to play an important role in both thromboxane A2 synthetase-inhibitory and bronchodilatory activities.
