摘要: Cardiovascular drugs such as lovastatin, simvastatin, amlodipine besylate, nifedipine, and hydralazine hydrochloride inhibit,cholesterol esterase (CEase) in vitro. In the present paper, an attempt was made to determine kinetically the reaction mechanism for CEase inhibition by these drugs. The inhibition constant, K-i, for the mixed-type inhibition of CEase by these drugs in the presence of triton-X-100 or taurochloate were measured. Moreover, the pK(i) values were correlated with the molecular weights of these drugs. In conclusion, the fact that these drugs lower cholesterol levels in the plasma low-density lipoprotein may be partially due to the CEase inhibition by these drugs.
