This invention provides that Ropinirole (4-[2-(Dipropylamino)ethyl]-1,3-dihydro-2H-indol-2-one) possess potent urease inhibitory potential (in vitro) with 97.3% inhibition and IC50=11.7+0.46 μM, when compared to the standard inhibitors i.e. acetohydroxamic acid (IC50=41.5+1.50 μM), and thiourea (IC50=21.0+0.50 μM).
