Compound having the NO production inhibitory action, process for the preparation of compounds having anti-allergic agents and NO production inhibitory action

摘要

PROBLEM TO BE SOLVED: To provide a new material having an NO-production-inhibiting activity, obtained from a natural product, and exhibiting antiallergic activities based on the NO-production-inhibiting activity; to provide a safe and high-performance antiallergic agent using the material having the NO-production-inhibiting activity as a base; and to provide a method for producing the material having the NO-production-inhibiting activity.;SOLUTION: The compound having the NO-production-inhibiting activity is represented by structural formula (1) or a similar structural formula. The antiallergic agent contains the material having the NO-production-inhibiting activity. The method for producing the material having the NO-production-inhibiting activity from the natural product is also provided.;COPYRIGHT: (C)2007,JPO&INPIT
