EndonucleaseIV 是一种 DNA 修复酶,属于脱嘌呤/脱嘧啶 (AP) 核酸内切酶。它具有针对 AP 位点的核酸内切酶活性,并具有 3' 磷酸二酯酶活性,能够去除 DNA 3' 端的各种连接阻断损伤。此外,EndonucleaseIV 对氧化性 DNA 损伤也有核酸内切酶活性,并具有 3' 至 5' 外切酶活性。
Cap-dependent endonuclease-IN-26, a potent inhibitor of cap-dependent endonuclease (CEN) with an IC50 of 286 nM, exhibits significant antiviral activity against a broad spectrum of influenza A and B strains [1].
pUL89 Endonuclease-IN-2 (Compound 15k) is a highly effective inhibitor of the pUL89 endonuclease of human cytomegalovirus (HCMV). With an IC50 of 3.0 μM, it exhibits potent antiviral activities [1].
