Diprovocim-X (compound 35) is a potent TLR1/TLR2 (toll-like receptor 1/2) agonist, with EC50 values of 0.14 and 0.75 nM for hTLR1/TLR2 and mTLR1/TLR2, respectively. Diprovocim-X is a potent adjuvant in vivo in mice, and serves to stimulate the adaptive immune response.
Diprovocim-X stimulates release of TNF-α from (human) differentiated THP-1 cells proves dependent on both TLR2 and TLR1, but notably independent of TLR6[1].
