1 Pseudocholinesterase and two human liver carboxylesterases [human liver carboxylesterase form 1 (hCE-1) and human liver carboxylesterase form 2 (hCE-2)] catalyze the rapid hydrolysis of ester linkages in cocaine. Cocaine carboxylesterase 2 Homo sapiens
2 Cocaine competitively inhibited hCE-1-, hCE-2- and pseudocholinesterase-catalyzed hydrolysis of heroin to 6-monoacetylmorphine (Ki = 530, 460 and 130 microM, respectively) and 6-monoacetylmorphine hydrolysis to morphine (Ki = 710, 220 and 830 microM, respectively).
