Abstract

The development of new preparations for managing skin lesions is a task requiring a complex research approach. Thus, one promising direction consists in the creation of new bases for wound-healing drugs for external application. Chemical compounds that can be used as such bases include polymeric hydrogels, representing spatially cross-linked macromolecules that swell in a solvent. This property provides an opportunity to load hydrogels with drugs of both synthetic and herbal origin. A search for a gel-forming polymer acting not only as a drug carrier, but also as a healing agent presents a relevant research task. In a previous work, the authors obtained polyhexamethylene guanidine hydrochloride hydrogels by crosslinking terminal amino groups with formaldehyde. The conducted studies of the wound-healing capacity of the obtained hydrogels and compositions on their basis confirmed their comparability with such widely-used agents, as levomecol, bepanthene, etc. In addition, the obtained compositions were found to exhibit their own activity. Therefore, hydrogels based on polyhexamethylene guanidine hydrochloride can be used as a promising platform for drug design. In this work, the destruction products released during hydrolysis of the hydrogel under study were investigated. IR and UV spectroscopy methods were applied to evaluate the concentration of hydrogel destruction products over time. A mechanism of hydrogel destruction yielding the initial polyhexamethylene guanidine hydrochloride and formaldehyde in a gem-diol form is proposed.
聚六亚甲基胍盐酸盐的水解研究
开发用于管理皮肤病变的新制剂是一项需要复杂研究方法的任务。因此,一个有希望的方向是创造外用伤口愈合药物的新基础。可以用作这种碱基的化合物包括聚合水凝胶,它代表在溶剂中膨胀的空间交联大分子。这一特性提供了将合成药物和草药药物装入水凝胶的机会。寻找一种既可作为药物载体又可作为愈合剂的凝胶形成聚合物是一项相关的研究任务。在以前的工作中,作者通过末端氨基与甲醛交联得到了聚六亚甲基胍盐酸盐水凝胶。在此基础上对所获得的水凝胶及其组合物的伤口愈合能力进行了研究,证实了其与左旋美康、倍苯等广泛使用的药物的可比性。此外,所获得的组合物显示出自己的活性。因此,以聚己亚甲基胍盐酸盐为基础的水凝胶可以作为一个很有前途的药物设计平台。研究了所研究的水凝胶在水解过程中所释放的破坏产物。采用红外和紫外光谱法对水凝胶破坏产物浓度随时间的变化进行了评价。提出了一种水凝胶破坏的机制,产生初始的聚六亚甲基胍盐酸盐和甲醛的宝石二醇形式。
