ML-161 is an allosteric, reversible inhibitor of proteinase-activated receptor 1 (PAR1) on platelets, preventing surface expression of P-selectin induced by the peptide SFLLRN with an IC₅₀ value of 0.26 μM. It blocks platelet activation induced by thrombin as well as by SFLLRN but not by PMA , U-46619 , or collagen.

ML 161 is a diaminobenzene derivative that acts as a selective inhibitor of platelet activation at protease-activated receptor 1 (PAR1). ML 161 has also been shown to inhibit thrombin-induced platelet activation.

ChEBI: 2-bromo-N-[3-(1-oxobutylamino)phenyl]benzamide is a member of benzamides.
