Carotegrast methyl (AJM300) 是一种口服有效和选择性 α4 整联蛋白 (α4 integrin) 拮抗剂。HCA2969 是 Carotegrast methyl 的活性代谢产物,是一种特异的双重 α4β1/α4β7 整联蛋白拮抗剂。Carotegrast methyl 可预防小鼠结肠炎。
生物活性 | Carotegrast methyl (AJM300) is an orally active and selectiveα4integrinantagonist. HCA2969, an active metabolite of Carotegrast methyl, is a specific and dual α4β1/α4β7integrin antagonist. Carotegrast methyl prevents the development of colitis in mice[1].
|
体外研究 (In Vitro) | HCA2969 inhibits human α4β1 integrin (KD=0.32 nM; IC50=5.8 nM), human α4β7 integrin (KD=0.46 nM; IC50=1.4 nM) and mouse α4β7 integrin (KD=0.2 nM; IC50=26 nM) in Jurkat, RPMI-8866 and TK-1 cell lines[1].

体内研究 (In Vivo) | Carotegrast methyl (AJM300; oral; 0.03-1%; for 15 days) prevents the development of colitis induced by transfer of IL-10 deficient CD4+T cells in mice[1]. Carotegrast methyl (oral; 0.3, 3, 30, or 30 mg/kg; a single oral) inhibits Lymphocyte homing to Peyer's patches and increases peripheral lymphocyte counts in a dose-dependent manner in BALB/c mice (8 weeks of age, female)[1].
Animal Model: | Mouse model of colitis induced by adoptive transfer of IL-10 deficient CD4+T cells[1] | Dosage: | Diet; 0.03, 0.1, 0.3 or 1% | Administration: | For 15 days | Result: | Had a histological improvement in epithelial cell hyperplasia, reduced inflammatory cell infiltration and a decrease in mucus production. Prevented an increase in the colon weight in a model of colitis induced by adoptive transfer of CD4+CD45RBhighT cells. |
