title: Stereoselectivity of binding of alpha-(N-benzylamino)benzylphosphonic acids to prostatic acid phosphatase.
abstract: The inhibition effects of enantiomerically pure alpha-(N-benzylamino)benzylphosphonic acids and their derivatives on human prostatic acid phosphatase have been investigated. As expected, (R)-alpha-(N-benzylamino)benzylphosphonic acid demonstrated higher affinity for the enzyme than (S)-enantiomer. At the same time, (1R,2S)-phenyl[(1-phenylethyl)amino]methylphosphonic acid was found to be a significantly weaker inhibitor than its (1S,2R)-analogue. The enantioselectivity has been explained using a molecular modeling approach by computational docking of inhibitors into active center of prostatic acid phosphatase.
