EIDD-2749 4'-FlU; 4'-Fluorouridine

产品介绍 EIDD-2749 (4'-Fluorouridine) 是一种口服有效的 RdRp 抑制剂。EIDD-2749 能有效抑制 RSVSARS-CoV-2 的复制。EIDD-2749 还表现出抗 HCV 和淋巴细胞性脉络丛脑膜炎病毒 (LCMV) 的活性。EIDD-2749 是一种很有潜力的 COVID-19 口服研究候选剂,也适用于其他 RNA 病毒的研究。
生物活性

EIDD-2749 (4'-Fluorouridine) is an orally active RdRp inhibitor. EIDD-2749 effectively blocks the replication of RSV and SARS-CoV-2. EIDD-2749 also exhibits activity against HCV and lymphocytic choriomeningitis virus (LCMV). EIDD-2749 is a promising oral therapeutic candidate for COVID-19 and is also suitable for research on other RNA viruses.

体外研究

EIDD-2749 induces a delayed stalling of phosphodiester bond formation by RSV and SARS-CoV-2 RdRP.
EIDD-2749 is rapidly anabolizes, metabolically stable, and potently antiviral in disease-relevant well-differentiated HAE cultures.
EIDD-2749 shows a ≥17-fold increase in anti-RSV potency relative to that on HEp-2 cells; however, the low cytotoxicity levels remains unchanged (CC50 169 mM), resulting in a high SI (SI = EC50/CC50) of ≥1877.
EIDD-2749 inhibits SARS-CoV-2 with an EC50 value of 0.2-0.6 M.
EIDD-2749 has an EC50 of 1.86 μM in theVero E6 cell line, cytotoxicity with a CC50 of 380 μM, and stability in human plasma.
