Relative binding affinity of the tethers bound to the targeting group for human androgen receptor were measured using a (3) H-Mibolerone competition assay and varied from 18% of nilutamide binding for the butynediol-based linear region to less than 1% for one of the piperazine derivatives.

Among them, 4-[4-cyano-(3-trifluoromethyl) phenyl]-N-(4-fluorophenyl) piperazine-1-carbo xamide (22; YM-92088) exhibited a potent AR antagonistic activity with an IC (50) value of 0.47 microM in the reporter assay, which is more potent than bicalutamide (4) which has an IC (50) value of 0.89 microM.
