纤维素苯碳酸酯是合成多种可溶性和功能性纤维素氨基甲酸酯的良好平台。在本研究中,讨论了氨基末端基团,即ω -氨基乙基纤维素-和ω -氨基乙基-对氨基苯基纤维素-氨基甲酸酯的合成。产物具有良好的水溶性,其结构可以通过核磁共振谱清晰地描述。氨基甲酸纤维素在体外表现出杀菌和杀真菌的活性。氨基乙基氨基甲酸酯对白色念珠菌和金黄色葡萄球菌具有较强的抑制活性(ic50分别为0.02 mg mL - 1和0.05 mg mL - 1)。对氨基苄胺(ABA)作为取代基可以提高其抗菌活性和细胞毒性。混合氨基甲酸酯纤维素具有较高的生物相容性(lc50为3.18 mg mL−1),在棉花和聚乙烯表面形成膜,具有较强的抗虫活性。aureusandKlebsiella肺炎。
Cellulose phenyl carbonates are an excellent platform to synthesize a broad variety of soluble and functional cellulose carbamates. In this study, the synthesis of cellulose carbamates with terminal amino groups, namely ω‐aminoethylcellulose‐ and ω‐aminoethyl‐p‐aminobenzyl‐cellulose carbamate, is discussed. The products are well soluble and their structures can be clearly described by NMR spectroscopy. The cellulose carbamates exhibit a bactericide and fungicide activity in vitro. The ω‐aminoethylcellulose carbamate possesses a strong activity againstCandida albicansandStaphylococcus aureus(IC50of 0.02 mg mL−1and 0.05 mg mL−1). The antimicrobial activity and cytotoxicity can be improved byp‐amino‐benzylamine (ABA) as an additional substituent. The mixed cellulose carbamate exhibits a high biocompatibility (LC50of 3.18 mg mL−1) and forms films on cotton and PES, which exhibit a strong activity againstS. aureusandKlebsiella pneumoniae.
