Studies demonstrated that cocaine-induced immunosuppression is mediated by metabolites of cocaine. Although SKF 525-A inhibited cocaine N-demethylation in liver S9 fractions isolated from female B6C3F1 mice, our study showed that pretreatment of mice

1. During hepatic microsomal oxidative metabolism, N-substituted amphetamines form complexes with cytochrome P-450 which absorb maximally at 455 nm.2. The formation of these metabolite-cytochrome P-450 complexes is inhibited by hexobarbital and SKF 5

1. The metabolism of papaverine was studied in vitro using the 9000 g fraction of rat liver. Apparent Km and Vmax values were 1.6 X 10-5 M and 34 nmol/g/min. Three monodemethylated metabolites were found by t.l.c. 2. Pre-treatment of rats with phenob

SKF 525-A induces several subpopulations of cytochrome P-450 which differ in their chromatographic properties and in their abilities to sequester themselves as metabolic-intermediate complexes. The two major subpopulations induced by SKF 525-A have b

1. 1. The reciprocal velocity plots of partially purified UDPglucuronosyltransferase of rat liver microsomes were concave suggesting negative co-operativity. The degree of curvature was not, however, as sharp as with plots obtained from native micros

Chlorpromazine (CPZ) and SKF 525-A above 0.01 mM inhibit the incorporation of alanine into protein in cultures of a clonal strain of rat hepatoma cells. Fifty per cent inhibition was noted for both drugs at approximately 0.07 mM, and at CPZ 0.15 mM 9
