Key Points

The study aims to develop bisarylthiourea derivatives as TLR2 agonists to enhance immune responses.
Designed and synthesized cycloalkyl-thiophene-3-carboxylate derivatives.
Evaluated structure-activity relationships for TLR2 activation.
Tested both TLR2/1 and TLR2/6 activation pathways.
Identified specific derivatives that preferentially activate TLR2/6 over TLR2/1.
Demonstrated increased immunomodulatory effects with selected compounds.

Implication

Novel bisarylthiourea derivatives activate TLR2/6, indicating potential in immunomodulation therapies.

Abstract

Toll-like receptor 2 (TLR2) acts as a pivotal family of pattern-recognition receptors that bridges innate and adaptive immunity through the detection of PAMPs and DAMPs. In pursuit of novel immunomodulators,...
