Background:

Englerin A is a potent and selective activator of TRPC4 and TRPC5 channels, with EC50s of 11.2 and 7.6 nM, respectively. Englerin A can induce renal carcinoma cells death by elevated Ca2+ influx and Ca2+ cell overload[1][2][3].

Englerin A (0.15-2500 nM; 48 h) characteristic concentration-dependent suppresses cells growth of the A-498 cells treated with the control siRNA while has little effect on the growth of cells treated with TRPC4 siRNAs[3].Englerin A (0.001nM-10 μM; 48 h) inhibits cells viability in HEK293T cells overexpressing TRPC5[3].Englerin A (3 nM; 1-240 s) evokes sustained elevation of the intracellular Ca2+ concentration within 1 min in HEK 293 cells over-expressing human TRPC4[1].Englerin A (0.1-1000 nM; 1-300 s) evokes intracellular Ca2+ elevations in A498 cells as well with an EC50 of 10 nM[1].

Englerin A (5 mg/kg; i.p daily except Sunday) markedly inhibits tumor growth during the 2-week treatment period in mice[4].
