The Wound Healing Potential of 2,3 Dimethylquinoxaline Hydrogel in Rat Excisional Wound Model

Background: 2,3-dimethylquinoxaline (DMQ) is a naturally occurring compound with documented antifungal activity. It showed also good in vitro physicochemical and pharmacokinetic characteristics.

Methods: The wound healing activity of 1% DMQ hydrogel in healthy adult male Wister rats were evaluated using the excision wound model. On day 7, the mean percentage closure of the wound area was determined. The animals were sacrificed on day 7 and skin was isolated for histology research and assessment of some inflammatory & oxidative markers, hydroxyproline and tissue growth factor.

Results and Discussion: Almost complete wound healing was observed after treatment with DMQ 1 % Jell for 7 days. The histological study confirmed marked attenuation of wound-induced histological changes. There was a marked reduction in TNF-α, IL-6 IL-β1 and NF-κB. levels. These data suggest the potential anti-inflammatory effect of DMQ.

Conclusion: DMQ has potential skin wound healing ability likely due to its anti-inflammatory mechanism. Further study is needed to confirm these preliminary findings and explore the molecular mechanism
