MK-1088
MK-1088 is an orally active A2A/A2B adenosine receptor antagonist with human A2A Ki of 0.31 nM, human A2B Ki 5.3 nM. MK-1088 blocks receptor downstream signaling, inhibits CREB phosphorylation and reverses adenosine-mediated immunosuppression. MK-1088 restores TNF−α release and enhances tumor immune surveillance. MK-1088 can be used for the research of cancer[1].

MK-1088 (Compound 46) (60 min at room temperature) potently binds to hA2AR expressed in CHO cell membranes with a Ki of 0.31 nM[1].
MK-1088 (60 min at room temperature) binds to hA2BR with a Ki of 5.3 nM, showing a 16-fold lower potency relative to hA2BR[1].
MK-1088 (60 min at room temperature) binds to hA1R expressed in CHO-K1 cell membranes with a Ki of 82 nM, showing 259-fold lower potency relative to hA2AR[1].
MK-1088 (0.1 nM-100 μM) dose-dependently inhibits NECA-stimulated CREB phosphorylation in human CD4+ T cells with an IC50 of 70 nM[1].
MK-1088 dose-dependently recovers LPS (HY-D1056)-stimulated, NECA (HY-103173)-suppressed TNF-α release in human whole blood[1].
MK-1088 has a clean off-target profile for cardiac ion channels and most CYP enzymes, with only moderate inhibition of CYP3A4-midazolam (IC50 = 4.1 μM) and no time-dependent CYP3A4 inhibition[1].
