Pharmacokinetic and toxicological in silco profiling of pluchine from the medicinal plant – Pluchea lanceolata

Abstract

Background: Pluchea lanceolata belongs to the genus Pluchea (family: Asteraceae). The medicinal herb has been used for various ailments to prevent joint swelling in arthritic disorders, rheumatism, and other neurological-inflammatory disorders. Pluchine, which in our review was found to be a compound from P. Lanceolata, is explored for possible pharmacokinetic and toxicological properties by in silico computational predictive tools. Aims and Objectives: The aim of the study is to profile the pharmacokinetic, toxicological, and drug likeness scores of pluchine’s active principle using computational analysis and prediction tools. Materials and Methods: The authenticated and validated chemical structure of pluchine with its chemical formula will be extracted from standard web-based tools PubChem and ChemSpider. The two-dimensional to three-dimensional (3D) structure conversion will be processed with ChemSketchonline software; the 3D structure output will be processed further to be screened for molecular and pharmacokinetic properties for absorption, distribution, metabolism, and elimination, followed by toxicity profiling through AdmetSAR software. Results: Pluchine active principle from P. lanceolata had a predictive pharmacokinetic profile of human intestinal absorption of <30%, Human skin permeability coefficients (log k p) of pluchine were −6.75 cm/s, and the blood–brain barrier were predicted to be positive with a probability score of 0.65. Drug likeness lipinskiscore is positive with -0- violations. Acute oral toxicity testing for pluchine predicts it to be placed in category III with LD50 values >500 mg/kg but <5000 mg/kg. Conclusion: The pluchineactive principle from P. lanceolata is predicted to have a favorable pharmacokinetic and drug-like property profile for lead compound development.
