Abstract
1. A metabolite of D-serine-cyclosporine A has been isolated from phenobarbital induced rabbit liver microsomes using hplc. 2. This metabolite was identified by FAB, electrospray mass spectrometry as well as nmr spectroscopy and is the result of metabolism of the vinylic methyl group of the 9-carbon amino acid unique to the cyclosporins, the first amino acid of this cyclic undecapeptide. This metabolite exhibits a significantly lower immunosuppressive activity than IMM-125 and CsA.
