The pharmacokinetics, metabolism, and excretion of a new antipsychotic drug, ziprasidone, were studied in four normal male volunteers after oral administration of a single 20 mg dose of a mixture of 14C- and 3H-labeled ziprasidone. Blood, urine, and feces were collected at various intervals for determination of total radioactivity and metabolic profiles. Eleven days after the dose, 20.3 +/- 1% ...

(4-Phenoxyphenylsulfonyl)methylthiirane (SB-3CT) is the selective inhibitor of matrix metalloproteinase 2 (MMP2). The inhibition mechanism of MMP2 by SB-3CT involves C-H deprotonation with concomitant opening of the three-membered heterocycle. In this study, the energetics of the deprotonation-induced ring-opening of (4-phenoxyphenylsulfinyl)methylthiirane, the sulfoxide analogue of SB-3CT, are...
