摘要:

采用高压均质技术制备了载有二氨基嘧啶氧化物(Kopexil)和吡咯烷基二氨基嘧啶氧化物(Kopyrrol)这两种防脱生发活性物的共输送纳米脂质体(Kopexil/Kopyrrol-LPs),其平均粒径为(81.2±1.3) nm,多分散系数PDI为0.104±0.006,Zeta电位为(-15.6±0.6) mV。纳米脂质体中Kopexil的载药量和包封率分别为22.1%和93.8%,Kopyrrol的载药量和包封率分别为11.0%和94.6%。采用Franz扩散池法研究Kopexil/Kopyrrol-LPs的体外释放和透皮特性,结果表明,纳米脂质体中Kopexil和Kopyrrol呈明显的缓释行为,其Kopexil的皮肤累积渗透量和滞留量分别为95.66和7.23 μg/cm 2,Kopyrrol的皮肤累积渗透量和滞留量分别为40.48和6.07 μg/cm 2。Kopexil/Kopyrrol-LPs中Kopexil和Kopyrrol的24 h皮肤滞留量分别较游离活性物提升约1.8和2.2倍。比较连续给药21天后雄激素脱发模型小鼠背部毛发生长情况以及皮肤组织切片,结果显示Kopexil/Kopyrrol-LPs组小鼠生发速度以及毛囊数量均显著高于游离活性物组。

Abstract:

The co-delivery nanoliposomes (Kopexil/Kopyrrol-LPs) containing two kinds of anti-alopecia agents (Kopexil and Kopyrrol) were prepared by high pressure homogenization technology. The mean particle size of the Kopexil/Kopyrrol-LPs was (81.2±1.3) nm, the PDI was 0.104±0.006, and the Zeta potential was (-15.6±0.6) mV. The drug loading efficiency and encapsulation efficiency of Kopexil in the nanoliposomes were 22.1% and 93.8%, respectively, and those of Kopyrrol were 11.0% and 94.6%, respectively. The in vitro release profiles and transdermal efficiency of the two agents in the Kopexil/Kopyrrol-LPs were studied by Franz diffusion cell method. Sustained release of the two agents from the Kopexil/Kopyrrol-LPs were demonstrated. The cumulative skin penetration and retention of Kopexil were 95.66 and 7.23 μg/cm 2, respectively, and those of Kopyrrol were 40.48 and 6.07 μg/cm 2, respectively. The 24 h skin retentions of Kopexil and Kopyrrol in Kopexil/Kopyrrol-LPs were approximately 1.8 and 2.2 times higher than that of free active agents, respectively. After 21 days of continuous administration of the Kopexil/Kopyrrol-LPs in the back skin of androgenetic alopecia murine models, the speed of hair growth and the number of hair follicles in the Kopexil/Kopyrrol-LPs group were significantly higher than those in the free active agents group, based on the hair growth and tissue section of the treated skin.
