Abstract
Gastric and duodenal ulcers are increasingly becoming global health burdens. The side effects of conventional treatments such as non-steroid anti-inflammatory drugs (NSAIDs), proton pump inhibitors (PPIs), antibiotics, and cytoprotective agents have necessitated the search for new medications. Plants are a rich source of active metabolites and herbal medicines have been used in the treatment of ulcers and cancers. In this study, we used in silico methods like molecular docking and MM-GBSA calculations to evaluate the effects of some anti-ulcer and anti-inflammatory phytochemicals on some key enzymes, cyclooxygenase (COX), and lipoxygenase (LOX), which are implicated in the protection and destruction of the gastric mucosa. The phytochemicals were retrieved from the literature and docked toward the binding sites of the three enzymes (COX-1, COX-2, and 5-LOX). Five compounds, rhamnetin, kaempferol, rutin, rosmarinic acid, and chlorogenic acid were observed to putatively bind to cyclooxygenase 2 (COX-2) and 5-lipoxygenase (5-LOX) but not to cyclooxygenase 1 (COX-1). The interaction mechanisms between these phytochemicals and the target proteins are discussed. The compounds' drug metabolism, pharmacokinetics, and toxicity have been evaluated to assess their suitability as potential next-generation anti-ulcer and anti-inflammatory drugs.
