ISAM-140

ISAM-140 is a selective non-xanthinic adenosine A_2B receptor antagonist. Discovered in 2016,^[1] it has a K_i of 3.49 nM on the A_2B receptor and >1000-fold selectivity with respect to the other three adenosine receptor subtypes. It has been shown to help the immune system to attack cancer cells in in vitro assays by rescuing T and NK cell proliferation, cytokine release, and TIL infiltration.^[2]
