Abstract
1. Inhibition of the conjugation of morphine and glucuronic acid, of phenol and sulfuric acid, and of p-aminobenzoic acid and glycine, and of urea synthesis by methyl-bis-(beta-chloroethyl)-amine HCl (MBA) is described.
2. Variations of the sensitivities of these reactions to the same concentration of MBA were found.
3. None of the compounds tested increased the amount of morphine conjugated, nor did any with the exception of protein overcome the MBA inhibition. Protein in the reaction mixture offered partial protection.
4. MBA inhibits the conjugation of morphine in concentrations which have little effect on respiration.
