1 Relationship between covalent binding to microsomal protein and the destruction of adrenal cytochrome P-450 by spironolactone. Spironolactone cytochrome P450 3A14 Cavia porcellus
2 Studies were done to evaluate the relationship between the destruction of cytochrome P-450 and the covalent binding to microsomal protein by SL and by 7 alpha-thiospironolactone (7 alpha-thio-SL), an obligatory intermediate in the activation pathway. alpha-thiospironolactone cytochrome P450 3A14 Cavia porcellus
3 However, all of the data are consistent with the hypothesis that 7 alpha-thio-SL is a suicide inhibitor of adrenal cytochrome P-450 and that covalent binding to protein is involved in the degradation of cytochrome P-450. 7 alpha-thiospironolactone cytochrome P450 3A14 Cavia porcellus
