Diabetic wounds remain a major medical challenge with often disappointing outcomes despite the best available care. An impaired response to tissue hypoxia and insufficient angiogenesis are major factors responsible for poor healing in diabetic wounds. Here we show that the antimycotic drug ciclopirox olamine (CPX) can induce therapeutic angiogenesis in diabetic wounds. Treatment with CPX in vitro led to upregulation of multiple angiogenic genes and increased availability of HIF-1α. Using an excisional wound splinting model in diabetic mice, we showed that serial topical treatment with CPX enhanced wound healing compared to vehicle control treatment, with significantly accelerated wound closure, increased angiogenesis, and increased dermal cellularity. These findings offer a promising new topical pharmacologic therapy for the treatment of diabetic wounds.
糖尿病性伤口仍然是一个主要的医学挑战,尽管提供了最好的治疗,但往往结果令人失望。组织缺氧反应受损和血管生成不足是导致糖尿病性伤口愈合不良的主要因素。在这里,我们表明抗真菌药物环吡酮胺(CPX)可诱导糖尿病性伤口的治疗性血管生成。体外 CPX 治疗导致多种血管生成基因的上调和 HIF-1α 的可用性增加。在糖尿病小鼠的切除性伤口夹板模型中,我们表明与载体对照治疗相比,连续局部 CPX 治疗可增强伤口愈合,显著加速伤口闭合、增加血管生成和增加真皮细胞密度。这些发现为治疗糖尿病性伤口提供了一种有前途的新的局部药物治疗方法。
