RLF-100(aviptadil)可快速抑制新型冠状病毒的复制!

2020-08-03 Allan MedSci原创

独立研究人员报告说,RLF-100(aviptadil)可阻断新型冠状病毒在人肺细胞和单核细胞中的复制。

RLF-100(aviptadil)是一种合成的人类血管活性肠多肽(VIP),已获得FDA快速通道指定。制药公司NeuroRx和Relief今日宣布,RLF-100(aviptadil)能够显著降低危重COVID-19患者因呼吸衰竭造成的死亡率。同时,独立研究人员报告说,RLF-100(aviptadil)可阻断新型冠状病毒在人肺细胞和单核细胞中的复制。

血管活性肠多肽(VIP)由Sami Said博士于1970年首次发现。尽管最早在肠道中被发现,但现在已知VIP会在整个人体中产生,并且主要集中在肺部。超过100个同行评审的研究显示,VIP在呼吸窘迫、急性肺损伤和炎症的动物模型中具有有效的抗炎/抗细胞因子活性。最重要的是,体内70%的VIP结合到肺泡II型细胞中,而肺泡II型细胞中对于氧气向人体的传播至关重要。

与COVID-19相关的死亡主要由呼吸衰竭引起。已知肺泡II型细胞具有高水平的血管紧张素转换酶2(ACE2)受体,ACE2可作为SARS-CoV-2进入细胞的途径。这些II型肺泡细胞在其细胞表面也具有高浓度的VIP受体,因此VIP预计能够特异性地保护这些细胞免受病毒侵袭。
