Anti-virulence factor-IN-3

Anti-virulence factor-IN-3 (Compound 21) is a covalent β-aminosulfinyl type anthrax edema factor (EF) inhibitor, with a K_i value of 0.44 μM. Anti-virulence factor-IN-3 generates an active ethylene sulfinyl intermediate, which forms an irreversible covalent bond with the Lys residue at the active center of EF, permanently inhibiting the adenylate cyclase activity of EF. Anti-virulence factor-IN-3 effectively inhibits the cAMP production induced by EF, with an EC₅₀ value of 0.15 μM. Anti-virulence factor-IN-3 can be used for research on anthrax Infection.

Protocols

All Signal Pathway Related

Research Protocol for Infectious Diseases
Infectious-disease experiments test how pathogens interact with host barriers, innate immune receptors, inflammatory signaling, pathogen replication, and tissue injury; pattern-recognition receptors such as TLRs, RIG-I-like receptors, NOD-like receptors, and inflammasomes detect microbial molecules and activate NF-κB, interferon, and cytokine responses. The central hypothesis is that infection severity reflects the balance between pathogen burden and host response: protective inflammation restricts pathogen growth, whereas excessive or mislocalized inflammation contributes to tissue damage and disease phenotype. Unresolved questions include which host pathways are protective versus pathogenic, why some infection models fail to translate to human disease, and which combined readouts best predict clinically relevant infection outcomes.

Help & FAQs

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
