Chemical Structure
INI-4001
- CAS No.: 2549050-07-7
- Formula:C59H109N6O13P
- Molecular Weight:1141.50
InChIKey: PGHXDXJDKBHTAD-WAEHRUBESA-N
SMILES: OC1=NC2=C(N)N=C(O[C@@H](C)CCC)N=C2N1CC3CCN(CCOP(OCCOCCOCCOC[C@H](OC(CCCCCCCCCCCCCCC)=O)COC(CCCCCCCCCCCCCCC)=O)(O)=O)CC3
Biological Activity: INI-4001 is a TLR7/8 agonist and vaccine adjuvant. INI-4001 regulates innate and adaptive immune responses by activating murine TLR7 and human TLR7/TLR8. INI-4001 enhances IgG and neutralizing antibody responses against Powassan virus (POWV), reduces viral loads in the brain, liver and spleen, provides complete protection against lethal POWV challenge, and skews immune responses toward a Th1 phenotype. When INI-4001 is used in combination with Al (OH)3 and SARS-CoV-2 RBD antigen, it efficiently adsorbs to Al (OH)3, promotes Th1 immunity and enhances SARS-CoV-2 neutralizing antibody responses. INI-4001 is applicable to research related to Powassan virus infection and COVID-19[1][2].
