CHIKV Inhibitor

CHIKV nsP2 protease-IN-1(compound J13) is an oral active non-structural protein 2 protease inhibitor with the EC₅₀ of 0.39 μM aganist of CHIKV S27. CHIKV nsP2 protease-IN-1 can be used for study of Chikungunya virus.

CHVB-066 is an alphavirus non-structural protein nsP1 inhibitor that exhibits varying degrees of inhibitory activity against nsP1 of CHIKV and VEEV. CHVB-066 inhibits MTase and GTase activities and disrupts the capping process of viral RNA, including inhibiting CHIKV replication, reducing progeny viruses, and preventing cytopathic effects. It shows varying degrees of inhibitory activity against nsP1 of CHIKV and VEEV but lacks anti-SFV replication activity, displays cross-resistance with MADTP series compounds, and requires nsP2/nsP3 mutations to develop complete drug resistance. This inhibitor with varying inhibitory activity against nsP1 of CHIKV and VEEV can be widely applied to relevant studies on chikungunya virus infection and chikungunya fever.

Amustaline (S-303) is a compound used for inactivating pathogens in blood components and belongs to the category of nucleic acid-targeted chemical decontaminants. Amustaline has the ability to inactivate viruses and is effective against mosquito-borne viruses such as Chikungunya virus (CHIKV), Dengue virus (DENV), and Zika virus (ZIKV). When combined with glutathione (Glutathione, GSH), which acts as a neutralizer to counteract adverse reactions, Amustaline ensures the stability of red blood cell membranes. Amustaline is mainly used for inactivating pathogens in red blood cell concentrates (RBCC) to reduce the risk of transfusion-transmitted infections (TTI).
