In SilicoInvestigations on Curcuminoids fromCurcuma longaas Positive Regulators of Wnt/β-catenin Signaling Pathway in Wound Healing

Curcuma longa (Turmeric) is a traditionally used herb in wound healing. The efficacy of fresh Turmeric paste to heal wound has already been investigated in multiple ethnobotanical studies. Wnt/β-catenin signaling pathway plays a significant role in wound healing and injury repair processes which has been evident in different in vitro studies. This study aims to analyze the potentiality of Curcuminoids (Curcumin I, Curcumin II and Curcumin III) from Curcuma longa to bind and enhance the activity of two intracellular signaling proteins-Casein Kinase-1 (CK1) and Glycogen Synthase Kinase-3β (GSK3B) involved in Wnt/β-catenin signaling pathway. Present study is largely based on computer-based molecular docking program which mimics the in vivo condition and works on specific algorithm to interpret the binding affinity and poses of a ligand molecule to a receptor. Curcumin I showed better affinity of binding with CK1 (−10.31 Kcal/mol binding energy) and Curcumin II showed better binding affinity (−7.55 Kcal/mol binding energy) for GSK3B. Subsequently, Drug likeness property, ADME/Toxicity profile, Pharmacological activity and Site of metabolism of the Curcuminoids were also analyzed. All of the ligand molecules showed quite similar pharmacological properties.
