Piezo Channel

D-GsMTx4 TFA, a selective spider venom peptide, is a TRPC1/6 and Piezo2 inhibitor that inhibits cation-permeable mechanosensitive channels (MSCs) belonging to the Piezo and TRP channel families, blocks cation-selective stretch-activated channels (SACs), and attenuates lysophosphatidylcholine (LPC)-induced astrocyte toxicity and microglia reactivity. toxicity and microglia reactivity.D-GsMTx4 TFA prevented myocardial infarction in a mouse model of ischemia/reperfusion and can be used to characterize the role of excitatory MSCs in normal physiology and pathology.

GsMTx4 TFA (1209500-46-8 free base) is a spider venom peptide that selectively inhibits cation permeable mechanosensitive channels (MSCs) belonging to the Piezo and TRP channel families.

Yoda 1 is an agonist of the Piezo1 channel that agonizes human- and mouse-derived Piezo1 (EC50=17.1 26.6 μM). Yoda 1 is also an inhibitor of glycine transporter protein 2 (GlyT2).

Dooku1 is an analog of Yoda1 and a selective antagonist of endogenous Piezo1 channels. Dooku1 inhibits Ca2+ entry induced by 2μMYoda1 with IC50 values of 1.3μM (in HEK 293 cells) and 1.5μM (in HUVEC). Dooku1 inhibits Yoda1-induced aortic relaxation.
