2‑Cl‑IB‑MECA regulates the proliferative and drug resistance pathways, and facilitates chemosensitivity in pancreatic and liver cancer cell lines. (PubMed, Int J Mol Med)
It was found that 2‑Cl‑IB‑MECA enhanced carboplatin and doxorubicin cytotoxic effects in the JoPaca‑1 and Hep‑3B cell lines, and a greater synergy was found in the highly tumorigenic JoPaca‑1 cell line...Other currently used conventional chemotherapeutics, fluorouracil and gemcitabine, showed synergy only when combined with high doses of 2‑Cl‑IB‑MECA. Notably, experiments with AAR‑specific antagonist, N‑[9‑Chloro‑2‑(2‑furanyl)(1,2,4)‑triazolo(1,5‑c)quinazolin‑5‑yl]benzene acetamide, revealed that 2‑Cl‑IB‑MECA had antitumor effects via both A3AR‑dependent and ‑independent pathways. In conclusion, the present study identified novel antitumor mechanisms of 2‑Cl‑IB‑MECA in pancreatic and hepatocellular carcinoma in vitro that further underscores the importance of A3AR agonists in cancer therapy.
