Abstract

A method for treating, resisting and alleviating endometriosis-associated pain, relating to the field of biological medicine, comprising administering, to an individual in need thereof, a therapeutically effective amount of a diaminopyrimidine compound of formula (I) or a pharmaceutically acceptable salt, an ester, a stereoisomer, a polymorph, a solvate, an N-oxide, an isotopically labeled compound, a metabolite or a prodrug thereof.

Claims (22)

1 .
