NSC-323241	Flavivirus	Infection
NSC-323241 is a potent STT3A-mediated mega protein complex assembly inhibitor. NSC-323241 disrupts he endoplasmic reticulum (ER) mega complex nucleated by STT3A during dengue virus (DENV) and Zika virus (ZIKV) infection. NSC-323241 targets the binding of STT3A subcomplex with viral nonstructural proteins (e.g., NS2B, NS3) and host translocon proteins, disrupting the formation of viral replication microenvironment. NSC-323241 is promising for research of flavivirus infection, such as dengue fever and Zika virus .

HY-P10668

Ac-EVKKQR-pNA	Dengue Virus Flavivirus	Infection
Ac-EVKKQR-pNA is a competitive chromogenic para-nitroanilide substrate corresponding to the P6-P1 segment amino-terminal to the *NS2B-NS3* cleavage site but with a more reactive, hydrolytically cleavable, para-nitroanilide at the P1’ position. Ac-EVKKQR-pNA is promising for research of dengue 2 virus and flavivirus virus infection .

HY-181991

IRBM-Z-2	Virus Protease Flavivirus	Infection
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 .

HY-156052

CN-716 dihydrochloride	Flavivirus Dengue Virus Virus Protease	Infection
CN-716 dihydrochloride is a reversible covalent flavivirus *NS2B·NS3* protease inhibitor with antiviral activity. CN-716 dihydrochloride effectively inhibits the replication of dengue virus (DENV2), West Nile virus (WNV) and Zika virus (ZIKV). The IC₅₀ values of CN-716 dihydrochloride against the proteases of the above three viruses are 0.066 μM, 0.11 μM and 0.25 μM, respectively, while the K_i values against the same proteases are 0.051 μM, 0.082 μM and 0.04 μM, respectively. CN-716 dihydrochloride can be used to study the infection mechanisms of dengue fever, West Nile fever and Zika virus infection .

Bz-Nle-Lys-Arg-Arg-AMC	Peptides	Others
Bz-Nle-Lys-Arg-Arg-AMC can be used for protease activity assay. In 0.1mL Tris-HCl buffer (50 mM, pH 7.8), Bz-Nle-Lys-Arg-Arg-AMC was hydrolyzed, and the release rate of AMC was observed .

HY-P10668

Ac-EVKKQR-pNA	Dengue Virus Flavivirus	Infection
Ac-EVKKQR-pNA is a competitive chromogenic para-nitroanilide substrate corresponding to the P6-P1 segment amino-terminal to the *NS2B-NS3* cleavage site but with a more reactive, hydrolytically cleavable, para-nitroanilide at the P1’ position. Ac-EVKKQR-pNA is promising for research of dengue 2 virus and flavivirus virus infection .

Western blot analysis of extracts from THP-1(lane 2(20μg), Jurkat (lane 3(20μg) and NIH3T3(lane 4(20μg) using FOXO1A (HY-P80132) Rabbit mAb. Proteins were transferred to a PVDF membrane and blocked with 5% non-fat milk in TBST for 2 hour at room temperature. The primary antibody (1/1000) and Loading control antibody (Beta Actin, HY-P80438, 1/10000) was used in 5% non-fat milk in TBST at 4°C overnight. Goat Anti-Mouse/Rabbit IgG-HRP Secondary Antibody (1/10000) was used for 1 hour at room temperature.
