一般描述

聚-L-组氨酸是一种两性化合物。结构中的咪唑环可进行质子化−去质子化反应。

应用

聚L-组氨酸已用于:
  • 作为聚阳离子分散多壁碳纳米管(MWCNT)
  • 作为多离子化合物研究其破坏细胞外包膜病毒膜的能力
  • 通过在细胞水平上和在体内的抗朊毒体(prion)分析,进行其抗朊毒体活性筛选

生化/生理作用

聚L-组氨酸(Phis)共聚物具有生物相容性、pH响应性和较低的毒性。它具有逃逸内溶酶体的功能。聚L组氨酸与聚乙二醇−聚(d,l-丙交酯) (PEG-PLA)的共聚物可有效递送阿霉素。pH敏感性聚l-组氨酸共聚物胶束可在酸性微环境中递送抗癌药物。

Poly(L-histidine) (PLH) with dimethylimidazole groups has been synthesized as a pH-sensitive polypeptide to control the stability of its small interfering RNA (siRNA) polyion complexes for RNA interference (RNAi). The resulting methylated PLH (PLH-Me) was water-soluble despite deprotonation of the imidazole

Many laboratories use recombinant UDP-glucuronosyltransferases (UGTs), expressed in baculovirus-infected insect cells, for drug glucuronidation studies. We have infected Sf9 insect cells with increasing amounts of recombinant baculovirus, encoding either UGT1A9 or UGT2B7, and measured both glucuronidation activity and immunodetectable UGT
