Omilancor

Omilancor (BT-11) is an orally active lanthionine synthetase cyclase-like receptor 2 (LANCL2) activator. Omilancor can be used for the study of psoriasis, inflammatory bowel disease (IBD), and Crohn's disease (CD)^[1][2][3]. In Vitro:LANCL2 engagement produces an increase of PKA, followed by an accumulation of cAMP in the cytoplasm. BT-11 treatment splenocytes shows a dose−response increase of cAMP production. BT-11 stimulates cAMP production by activating the LANCL2 pathway^[1]. In Vivo:The oral treatment with BT-11 (8 mg/kg/d) in a mouse model of inflammatory bowel disease results in lowering the disease activity index, decreasing colonic inflammatory lesions by 4-fold, and suppressing inflammatory markers (e.g., TNF-α, and interferon-γ) in the gut. Furthermore, studies in LANCL2^−/− mice demonstrates that loss of LANCL2 abrogates beneficial actions of BT-11, suggesting high selectivity for the target. Oral treatment with BT-11 (8 mg/kg/day) ameliorates colitis in mice. Initial safety assessment in rats indicates that oral treatment with BT-11 at high doses has an excellent safety profile up to 1000 mg/kg/day^[1]. BT-11 is well tolerated in rats, and may hold promise as an orally active therapeutic for Crohn’s disease. One hour after oral administration of a single dose of 80 mg/kg, BT-11 has a maximal concentration of 21 ng/mL; the half-life is 3 hours^[2].
