ABSTRACT
Wound healing involves several cellular and molecular pathways. Tridax procumbens activates genetic pathways with antibacterial, antioxidant, anticancer, and anti-inflammatory properties, aiding wound healing. This study purified Procumbenase, a serine protease from T. procumbens extract, using gel filtration (Sephadex G-75) and ion exchange (CM-Sephadex C-50) chromatography. Characterization involved analyses of protease activity, RP-HPLC, SDS-PAGE, gelatin zymogram, PAS staining, mass spectrometry, and circular dichroism. Optimal pH and temperature were determined. Protease type was identified using inhibitors. Wound-healing potential was evaluated through tensile strength, wound models, hydroxyproline estimation, and NIH 3T3 cell scratch analysis. In incision wound rat models, Procumbenase increased tensile strength on day 14 more than saline and Povidoneiodine. It increased wound contraction by 89 % after 10 days in excision wound models, attaining full contraction by day 15 and closure by day 21. Scarless wound healing was enhanced by 18 days of epithelialization against 22 and 21 days for saline and povidoneiodine. Procumbenase increased hydroxyproline concentration 2.53-fold (59.93 ± 2.89 mg/g) compared to saline (23.67 ± 1.86 mg/g). In NIH 3 T3 cell scratch assay, Procumbenase increased migration by 60.93 % (50 µg) and 60.57 % (150 µg) after 48 h. Thus, Procumbenase is the primary bioactive molecule in T. procumbens, demonstrates scar-free wound healing properties.
