In silico investigation of mitragynine and 7-hydroxymitragynine metabolism

Geometric and energetic data from ab initio calculations of haloethene, haloimine, halomethylenephosphine, haloiminophosphine, halodiazene, halodiphosphene and halocyclopropane

This article presents theoretical data on geometric and energetic features of halogenated compounds of ethene (C Created by potrace 1.16, written by Peter Selinger 2001-2019 ]]>C), imine (CN), methylenephosphine (CP), iminophosphine (NP), diazene (NN), diphosphene (PP) and cyclopropane (Δ). The data were obtained from ab initio geometric optimization and frequency calculations at HF, B3LYP, MP2 and CCSD levels of theory on 6–311++G(d,p) basis set. Input structures were generated by shell scripts and run by Q-Chem quantum chemical package. The output files were processed to extract geometric and energetic information by Wolfram Mathematica.

An in silico investigation of menthol metabolism

Prevalence of mentholated products for consumption has brought great importance to studies on menthol’s metabolic pathways to ensure safety, design more potent derivatives, and identify therapeutic benefits. Proposed pathways of (-)-menthol metabolism based on metabolites found experimentally in previous works by Yamaguchi, Caldwell & Farmer, Madyastha & Srivatsan and Hiki et al. were not in agreement. This in silico approach is based on the three in vivo studies and aims to resolve the discrepancies. Reactions in the pathways are conjugation with glucuronic acid/sulfate, oxidation to alcohol, aldehyde & carboxylic acid, and formation of a four-membered/five-membered ring. Gas-phase structures, standard Gibbs energies and SMD solvation energies at B3LYP/6-311++G(d,p) level were obtained for 102 compounds in the pathways. This study provides a more complete picture of menthol metabolism by combining information from three experimental studies and filling missing links in previously published pathways.
