General description
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。
Application
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
Biochem/physiol Actions
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。

Two methoxyl poly(ethylene glycol)-poly(L-histidine)-poly(L-lactide) (mPEG-PH-PLLA) triblock copolymers with different poly(L-histidine) chain lengths were synthesized. The morphology and biocompatibility of these self-assembled nanoparticles was investigated. Doxorubicin, an antitumor drug, was trapped in the nanoparticles to explore their drug-release behavior. The drug-loaded

Förster resonance energy transfer (FRET) from luminescent terbium complexes (LTC) as donors to semiconductor quantum dots (QDs) as acceptors allows extraordinary large FRET efficiencies due to the long Förster distances afforded. Moreover, time-gated detection permits an efficient suppression of autofluorescent

Semiconductor quantum dots (QDs) demonstrate select optical properties that make them of particular use in biological imaging and biosensing. Controlled attachment of biomolecules such as proteins to the QD surface is thus critically necessary for development of these functional nanobiomaterials.

For long-term, sustained protein delivery, a new, star-shaped block copolymer composed of methoxy poly(ethylene glycol) (mPEG), branched oligoethylenimine (bOEI), and poly(l-histidine) (pHis) was synthesized via the multi-initiation and ring-opening polymerization (ROP) of His N-carboxy anhydride (NCA) on bOEI with a
