Biological Activity for CGS 15943

CGS 15943 is a potent adenosine receptor antagonist (K_i values are 3.5, 4.2, 16 and 51 nM for human A₁, A_2A, A_2B and A₃ receptors respectively). Inhibits the catalytic subunit of the class IB PI3K isoform p110γ (IC₅₀ = 1.1 μM). Blocks HCC and HDAC cell proliferation in vitro via inhibition of the PI3K/Akt pathway; reduces proliferation of ER⁺ breast cancer cells. Also acts as a BMP-4 mimetic to stimulate osteogenic differentiation. Orally active in vivo.
