Abstract

Background: Using computational tools in drug discovery advanced the research in identifying new drug candidates for the benefit of the pharmaceutical industry and assessing the safety and pharmacokinetic profiles of phytochemicals. Understanding the inflammatory mechanism is not possible, but inflammatory signal transduction by cytokines can be mitigated by using the flavonoid class of drugs like flavonols. Methodology: A molecular docking study of flavonol compounds with proteins linked with inflammation was carried out using the AutodockVina program. SwissADME and pkCSM modules were used to assess the pharmacokinetic features of plant products. Compared to commercially available NSAIDs, flavonols had more excellent molecular docking scores. Results: Calculation of ADME features of flavonols with no carcinogenicity and low oral acute toxicity level. Compared to anti-inflammatory medicines, the Rutin docking score against COX-I (-8.7 kcal/mol) and the Galangin docking score against COX-II enzymes (-9.4 kcal/mol) had higher values. Discussion: Molecular docking studies exhibited the highest docking score for COX-I is Rutin -8.7 Kcal/mol and hydrogen bond with THR-89, PRO-84, LS-468, GLY-471, PHE-470. The highest docking for COX-II is Galangin -9.4 Kcal/mol and hydrogen bonding with VAL-349 and TYR-385. ADME/T studies were performed for all the flavonols. Rutin has the highest violations in drug-likeliness studies.  Conclusion: Flavonols may be more effective anti-inflammatory medicines than commercial medications. By modifying the pharmacokinetic features of plant products through diverse formulation strategies, we can get these phytochemicals to their target sites with fewer adverse effects.

Abstract

Background: Computational tools are advancing in the drug discovery process to assess the safety profiles of new compounds with reduced investment. Herbal remedies exhibit a diverse range of active compounds that can alleviate various disease conditions with fewer side effects. Method: This study investigates the molecular docking of phytochemicals from Matricaria Chamomilla against inflammation-induced skin disorders, such as psoriasis. Using AutoDock Vina and MGL Tools, key compounds were evaluated for binding affinity with target proteins. ADMET analysis, as assessed by pkCSM and SWISSADME, to predict the Lipinski’s Rule of Five. Redocking was implemented to confirm the binding affinity of the docked position. Results: This molecular docking of phenolic compounds and flavonoids, including quercetin, apigenin, rutin, luteolin, and various glycosylated derivatives—from Matricaria Chamomilla against cellular proteins implicated in psoriasis (PDE-4, p38MAPK, IL-23, BTK, JAK-3, TNF-α, IL-17A, and IL-6). Using Autodock Vina and MGL Tools, rutin and quercetin demonstrated favourable binding affinities. At the same time, luteolin-7-glycoside exhibited the highest docking scores (e.g., -10.8 kcal/mol for PDE-4, -9.7 kcal/mol for JAK-3, and -9.1 kcal/mol for TNF-α) compared to the standard. Results highlight the potential of chamomile phytochemicals as safe, orally effective agents for managing inflammatory skin conditions. Redocking confirms the RMSD values are within the limits of < 2 A0. Conclusion: The data suggest that chamomile flavonoids could be safe and beneficial for treating inflammatory diseases and psoriasis. Although enzymatic and cell-based assays, along with further preclinical evaluations, are essential for advancing research in disease modification, formulation strategies play a role in improving drug characteristics
