HeE1-2Tyr 是一种 pyridobenzothiazole，是一种黄病毒 RNA 依赖性 RNA 聚合酶 (RdRp) 抑制剂。HeE1-2Tyr 在体外显着抑制西尼罗河、登革热和 SARS-CoV-2 RdRps (IC₅₀ 为 27.6 µM) 的活性。

HeE1-2Tyr, a pyridobenzothiazole compound, is a flavivirus RNA dependent RNA polymerases (RdRp) inhibitor. HeE1-2Tyr significantly inhibits West Nile, Dengue and SARS-CoV-2 RdRps (IC 50 of 27.6 μM) activity in vitro.

HeE1-2Tyr shows antiviral activity, it is able to inhibit an Ugandan strain of West Nile virus with an IC50 of 2.1 μM, as well as all the four Dengue virus (DENV) serotypes, with IC50 ranging from 6.8 to 15 μM. The cytotoxicity of HeE1-2Tyr versus Vero E6 cells is ~115 μM.
Additionally, upon infection of human HEK 293 cells (CC50 of 50 μM), HeE1-2Tyr inhibits clinical strains of yellow fever virus with IC50 values ranging from 3.9 to 12 μM.
HeE1-2Tyr completely inhibits the replication of both SARS-CoV-2 and Feline coronavirus (FIPV). has not independently confirmed the accuracy of these methods. They are for reference only.
