An enzyme responsible for the ketone-reduction of 4-benzoylpyridine (4BP) was purified 350-fold to homogeneity from the cytosolic fraction of rabbit heart. The purified enzyme exhibited a molecular mass of 110 kDa on gel filtration, and 27 kDa on SDS-PAGE, indicating

4-Acetylpyridine, earlier reported by us to be an anticonvulsant, offers long-lasting protection after a single administration against hypothermic restraint stress-induced gastric ulceration in mice. Electroshock convulsions, marginally but not significantly protective against such ulcers themselves, when coupled with 4-acetylpyridine administration

Measurements of striatal choline acetyltransferase (ChAT) and glutamic acid decarboxylase (GAD) activities indicated that systemic administration of 4-8 mg/kg of MK-801 to rats completely blocked neuronal damage due to intrastriatal injections of 75-150 nmol of quinolinic acid. Similar experiments with

Carbonyl reductase from rabbit kidney was rapidly inactivated by diethylpyrocarbonate (DEPC). A similar inactivation was observed in photooxidation of the enzyme by methylene blue. The inactivation by DEPC was time- and concentration-dependent and followed pseudo-first-order kinetics. The results obtained from
