    两亲性磺化聚碳酸酯可在几秒钟内灭活 SARS-CoV-2
    摘要:
    自 2019 年爆发以来,严重急性呼吸综合征冠状病毒 2 (SARS-CoV-2) 引起的全球大流行已导致全球超过 6.61 亿人感染,超过 660 万人死亡。迫切需要安全有效的抗病毒解决方案,特别是那些具有快速灭活动力学的物质,有助于防止病毒传播。在这项研究中,我们报告了两亲性磺化聚碳酸酯的设计和合成,并研究了聚碳酸酯组合物对其抗病毒活性的影响。具有亲水性阴离子磺酸盐 (∼30%) 和疏水性n的最佳平衡的聚碳酸酯-丁基 (~70%) 悬垂基团可在几秒钟内灭活溶液中的各种类型的冠状病毒,包括 huCoV-OC43、祖先野生型 SARS-CoV-2 和 delta 变体,同时对哺乳动物细胞表现出低细胞毒性(即, Vero E6) 处于杀病毒浓度。这种两亲性磺化聚碳酸酯可能是一种很有前途的灭活病毒的解决方案,可用作预防病毒感染的喷雾剂。

  • Controlled synthesis of sulfonated block copolymers having thermoresponsive property by RAFT polymerization of vinyl sulfonate esters
    作者:Hideharu Mori、Yosuke Saito、Eri Takahashi、Kazuhiro Nakabayashi、Atsuhiko Onuma、Makoto Morishima
    DOI:10.1016/j.polymer.2012.06.043
    日期:2012.8
    Four vinyl sulfonate ester derivatives, methyl ethenesulfonate (MES), ethyl ethenesulfonate (EES), 2,2,2-trifluoroethyl ethenesulfonate (TFES), and 2,2,2-trichloroethyl ethenesulfonate (TCLES), which are protected forms of vinyl sulfonic acids, were polymerized by reversible addition-fragmentation chain transfer (RAFT) polymerization. Polymers having relatively narrow molecular weight distributions and pre-determined molecular weights were obtained by the polymerization of all monomers using a suitable xanthate-type chain transfer agent (CTA). The RAFT polymerizations of EES and TCLES were found to proceed in controlled fashions under suitable conditions, as confirmed by the formation of narrow polydispersity products, molecular weights controlled by the monomer/chain transfer agent ratio, and linear increases in molecular weight with conversion. Deprotection of the ethyl group of poly(EES) by LiBr in refluxing 2-butanone proceeded smoothly to give water-soluble poly(lithium vinyl sulfonate). Poly(potassium vinyl sulfonate) was also obtained by the deprotection of poly(TCLES) using potassium tert-butoxide. The syntheses of thermoresponsive block copolymers involving poly(lithium vinyl sulfonate) segments were conducted by RAFT polymerization of N-isopropylacrylamide using poly(EES) macro-CTA, followed by deprotection. The thermally-induced phase separation behavior and assembled structures of the block copolymers were also studied in aqueous solution. (C) 2012 Elsevier Ltd. All rights reserved.
