Abstract

A series of 2‐(1‐methyl‐3‐n‐propylpyrazol‐5‐yl)‐chromones with interesting Phosphodiesterase IV inhibitition activities were synthesized. Different derivatives of the titled compounds like aminopyrimidine, thiopyrimidine, pyrazolyl were synthesized and their Phosphodiesterase IV inhibitition activities were checked.
