title: Use of structure-activity relationships to estimate antiallergic activity of 4-hydroxy 3-nitro coumarins.
abstract: The antiallergic activity of a series of 4-hydroxy 3-nitro coumarins was studied using Hansch equations and CNDO/2 calculations. Following these calculations a new compound was synthetised which presents an interesting activity.
