Attenuation of Sunitinib-induced cardiotoxicity through the A3 adenosine receptor activation.

Sunitinib is an anti-cancer tyrosine kinase inhibitor associated with severe cardiotoxic adverse effects. Using rat Langendorff heart model and human acute myeloid leukaemia 60 (HL60) cell line we detected the involvement of protein kinase C (PKC) α during Sunitinib-induced cardiotoxicity and the effect of Sunitinib on cancer progression. The cardioprotective and anti-cancer properties of the A3 adenosine receptor agonist 2-chloro-N6-(3-iodobenzyl)-adenosine-5′-N-methyluronamide (IB-MECA) were investigated.
