Antagonists of slow-reacting substance of anaphylaxis. 1. Pyrido[2,1-b]quinazolinecarboxylic acid derivatives
摘要:
Members of a series of basic amide and ester derivatives of 2-substituted pyrido[2,1-b]quinazoline-8-carboxylic acids were prepared and evaluated for their ability to prevent slow-reacting substance of anaphylaxis (SRS-A) induced contractions of guinea pig ilea. The results indicate that the presence of a branched-chain alkyl group in the 2-position and a sterically demanding substituted aminoethyl carboxylate or carboxamide in the 8-position give optimal in vitro activity. The phenylpiperazine 25 was further found to block SRS-A-related symptomatology after intravenous administration in two animal models.
