Description: RQ-00203078 is a potent, selective and orally active TRPM8 antagonist (IC50 values are 5.3 and 8.3 nM for rat and human channels respectively). RQ-00203078 blocks TRPM8 activity and reduces the invasion potential of oral squamous carcinoma cell lines. RQ-00203078 (RQ) profoundly reduced such agonist-induced cation currents. TRPM8 is reportedly an important player in carcinogenesis in human prostate cancer. 6).
