This research was performed to analyze the antinociceptive task of methanolic extract of Ipomoea
marginata in addition to in silico evaluation of the antinociceptive task of the separated constituents from
Ipomoea marginata versus cyclooxygenase-2 enzyme together with absorption, distribution, metabolism,
excretion/toxicity analysis of separated substances. In vivo antinociceptive task of methanolic extract of
Ipomoea marginata was examined by acetic acid-induced agonizing, tail immersion and the hot plate on
rodents. In silico activity of the isolated substances, absorption, distribution, metabolism, excretion/toxicity
assessment was carried out by Autodock 4.0 and data warrior software applications. The results revealed
that methanolic extract of Ipomoea marginata has the greatest possible dose-dependent antinociceptive
task at all doses. Amongst the substances, ipalbidine showed the very best docking score of -8.26, which
was virtually better than standard diclofenac, i.e., -7.03, guaranteeing good binding compatibility among
the ligand and the receptor than the standard and absorption, distribution, metabolism, excretion/toxicity
evaluation using data warrior assures the compound has not breached Lipinski's guideline of five suggesting
its safety consumption. To conclude, Ipomoea marginata can be a potent resource of antinociceptive activity
and also additional simulation studies are needed to develop the performance of ipalbidine.
