Nitric oxide-releasing polymer incorporated ointment for cutaneous wound healing

초록

This work demonstrates the development of nitric oxide-releasing ointment and its potential on efficient wound healing. Nitric oxide-releasing polymer was successfully synthesized, which is composed of biocompatible Pluronic F127, branched polyethylenimine and 1-substituted diazen-1-ium-1,2-diolates. The synthesized nitric oxide-releasing polymer was incorporated into the PEG-based ointment which not only facilitated nitric oxide release in a slow manner, but also served as a moisturizer to enhance the wound healing. As compared to control groups, the nitric oxide-releasing ointment showed the accelerated wound closure with enhanced re-epithelialization, collagen deposition, and blood vessel formation in vivo. Therefore, this nitric oxide-based ointment presents the promising potential for the efficient strategy to heal the cutaneous wound. (C) 2015 Elsevier B.V. All rights reserved.
