Selective two pore segment channel 2 (TCP2) agonist that preferentially mimics the Ca2+ signals-inducing action of NAADP.
TPC2-A1-N is a selective two pore segment channel 2 (TCP2) agonist that mimics the action of NAADP where it selectively induces fast Ca2+ signals (EC50 = 7.8 µM) in a TCP2-dependent manner, without potency toward TRPML1/2/3. In contrast, TPC2-A1-N is a much weaker Na+ current inducer when compared to PI(3,5)P2 and TPC2-A1-P. TPC2-A1-N, but not the Na+ signals agonist TPC2-A1-P causes TPC2-dependent alkalinization of lysosomal lumen Ca2+ stores (10 µM, TPC2-expressing HeLa cells), while TPC2-A1-P, but not TPC2-A1-N, activates TPC2-dependent lysosomal exocytosis (30 µM, murine macrophages).

The first racemic total synthesis of the isoquinoline-benzylisoquinoline alkaloid muraricine is reported herein. Pharmacological characterization identified muraricine as a moderate inhibitor of P-glycoprotein, a crucial factor of multidrug resistance in cancer. When combined with vincristine, muraricine partly reversed the chemoresistance of
