The present research evaluates the wound healing capacity of dehydroabietylamine, a diterpenoid isolated from methanolic leaves extract of Carthamus tinctorius L. (Asteraceae). The wound healing activity was screened by excision, incision, and dead space wound models on albino rats and for the angiogenic property using chick chorioallantoic membrane (CAM) assay. Significant increase in wound contraction rate, skin breaking strength, granuloma strength, and dry granuloma weights was observed as compared to control. The pro-healing action may be due to increasing in collagen deposition as well better alignment and maturation. In CAM assay, the dehydroabietylamine showed increased angiogenic zone formation in the developing embryos compared to normal embryos and evidenced pro-angiogenic activity of the active constituent. Further, in silico comparative docking of dehydroabietylamine, standard drug nitrofurazone and positive control CHIR_98014 to ATP-binding active pocket of glycogen synthase kinase3-b (GSK3-b) protein that consisted of Tyr216 as a catalytic residue, with residues Asn64, Gly65, Ser66, Phe67, Gly68, Val70, Lys85, Leu132, Val135, Asp181, Lys183, Gln185, Asn186, and Asp200 in the active pocket docked with dehydroabietylamine at the torsional degree of freedom 0.5 U with Lamarckian genetic algorithm showed the inhibition constant of 315.6 9 10-9. But the inhibition constant of nitrofurazone and CHIR_98014 was 34.76 9 10-6 and 4.64 9 10-6 respectively. Docking of dehydroabietylamine to GSK3-b protein involved in Wnt signaling pathway supported the research on wound healing property. The above said studies explore the role of dehydroabietylamine in wound healing activity.
