Endothelium-independent relaxation of rabbit coronary artery by 17 beta-oestradiol in vitro.

abstract：BACKGROUND AND PURPOSE:Ca(2+)-dependent Cl(-) secretion (CaCC) in airways and other tissues is due to activation of the Cl(-) channel TMEM16A (anoctamin 1). Earlier studies suggested that Ca(2+) -activated Cl(-) channels are regulated by membrane lipid inositol phosphates, and that 1-O-octyl-2-O-butyryl-myo-inositol 3,...

abstract：BACKGROUND AND PURPOSE:(-)-Englerin A (EA) is a potent cytotoxic agent against renal carcinoma cells. It achieves its effects by activation of transient receptor potential canonical (TRPC)4/TRPC1 heteromeric channels. It is also an agonist at channels formed by the related protein, TRPC5. Here, we sought an EA analogue...
