Ac2-12, an annexin/lipocortin 1 (LC1)-mimetic peptide, inhibit neutrophil extravasation. Ac2-12 has antimigratory action and inhibits recruitment of neutrophils in experimental inflammation models[1][2].

In Vivo	Ac2-12 (i.v.; 6.7 mg/kg, ≈70 nmol per mouse), was found to mimic the actions of lipocortin 1 (LC1) and Ac2-26 in male Swiss Albino mice (10-15 g)[1]. Ac2-12 (100 μg) significantly reduces polymorphonuclear leukocyte (PMN) influx in wild-type C57BL/6 mice and is no longer active in FPR KO mice[2].
