生物活性

IRBM-Z-2 is a non-competitive, orally active Zika virus (ZIKV) NS2B-NS3 protease inhibitor, with IC50 values of 0.04 μM and 3.1 μM against the wild-type and I156T mutant strains, respectively. IRBM-Z-2 exhibits broad-spectrum anti-flavivirus potential, with IC50 values of 2.1 μM and 0.09 μM against the NS2B-NS3 proteases of dengue virus 2 (DENV2) and West Nile virus (WNV), respectively. IRBM-Z-1 inhibits ZIKV replication and alleviates virus-induced cytopathic effects. IRBM-Z-1 can be used in studies related to ZIKV infection[1].

体外研究
(In Vitro)

IRBM-Z-2 在生化实验中可抑制 DENV2 NS2B-NS3T156I 突变体蛋白酶的活性,其 IC50 为 0.4 μM,与野生型蛋白酶相比显示出更强的效力[1]
IRBM-Z-2 (72 h) 可强效抑制 Vero 细胞中野生型寨卡病毒 (ZIKV) 复制子的复制,其 EC50 为 0.03 μM,在浓度高达 32 μM 时未检测到细胞毒性[1]
IRBM-Z-2 (72 h) 可抑制 Vero 细胞中 ZIKV I156T 突变体复制子的复制,其 EC50 为 0.79 μM,在浓度高达 32 μM 时未检测到细胞毒性,相较于野生型复制子显示出效力降低的特征[1]
IRBM-Z-2 (72 h) 可抑制 Vero 细胞中 WNV 复制子的复制,其 EC50 为 0.31 μM,在浓度高达 32 μM 时未检测到细胞毒性[1]
IRBM-Z-2 (6 天) 可强效抑制 ZIKV PRVABC59 毒株在 BHK-21 细胞中诱导的致细胞病变效应 (CPE),其 EC50 为 0.016 μM,且在浓度高达 37.9 μM 时未检测到细胞毒性[1]
IRBM-Z-2 (48 h) 可在 HuH-7 细胞中抑制 ZIKV Padova 株和 H/PF/2013 株,表观 IC50 值为 6 至 20 nM,在测试浓度下未检测到细胞毒性[1]
IRBM-Z-2 (6 天) 可抑制西尼罗河病毒 Kern 515 株在 Vero76 细胞中诱导的致细胞病变效应 (CPE),其 EC50 为 1.0 μM,在浓度高达 50 μM 时未检测到细胞毒性[1]

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
