Carotegrast, an orally available α4 integrin receptor inhibitor, has anti-inflammatories activities.

Carotegrast methyl (AJM300), an orally-active small molecule, can antagonize the α4 integrin receptor. It is a specific and dual α4β1/α4β7 integrin antagonist.

Carotegrast methyl, also known as AJM300 and PTC-100, is an orally-active small molecule that antagonises the α4 integrin receptor. AJM300 reduces inflammation by blocking leucocyte trafficking. Oral treatment with AJM300 dose-dependently inhibited lymphocyte homing to Peyer's patches and increased the peripheral lymphocyte count in the same dose range. AJM300 dose-dependently prevented the development of experimental colitis in mice.

AM-8508 is a potent and selective PI3Kδ inhibitor. AM-8508 showed good cellular potency (in vitro pAKT IC50 = 4.6 nM ). AM-8505 xhibited excellent HWB potency (HWB (pAKT) IC50 = 2.7 nM). AM-8508 inhibit KLH-specific antibodies in animal models, signifying its potential for the treatment of human inflammatory diseases. PI3Kα and PI3Kβ are ubiquitously expressed and play a role in cell growth, division, and survival.
