Abstract
Background: An elucidation study was carried out to evaluate 19 different methylthiomorpholine, methylmorpholine and piperidine compounds as possible inhibitors of the Angiotensin Converter Enzyme (ACE) using as a positive blank: Captopril, drug used as an antihypertensive agent and known for its biological effect over ACE. Also, the interaction using Hippuryl-histidyl-leucine (HHL) as an artificial substrate was simulated.
Methods: The study was made using the Molecular Operating Environment (MOE), SYBYL and Gaussian software.
Results: All the molecular recognition process was performed under the conditions reported for such interaction, in order to emulate the experimental parameters as close as is possible to a real system.
Conclusion: After the calculations the best candidates for the ACE inhibition were determined.
Keywords: Antihypertensive, angiotensin converting enzyme, inhibition, molecular modeling, molecular recognition, hybrid QM/MM.
