Chemicals & Small Molecules

Parstatin(mouse) (Legacy Tebubio ref. 282TP1966). Cell-permeable peptide cleaved from protease-activated receptor 1 (PAR1) upon receptor activation. Attenuates endothelial cell migration and proliferation (IC50 ~ 20 μM), and induces cell cycle arrest. Promotes activation of caspase-3 and exhibits pro-apoptotic activity in vitro. Inhibits angiogenesis and exhibits cardioprotective activity in vivo.

Phrixotoxin 3 (Legacy Tebubio ref. 282TP1967). Potent blocker of voltage-gated sodium channels (IC50 values are 0.6, 42, and 72 nM for NaV1.2, NaV1.3 and NaV1.5 respectively). Blocks inward sodium currents in a voltage-dependent manner.

ProTx-I (Legacy Tebubio ref. 282TP1968). Selective CaV3.1 channel blocker (IC50 values are 0.2 and 31.8 μM for hCaV3.1 and hCaV3.2 respectively). Also reversibly inhibits NaV1.8 and blocks KV2.1 channels.

ProTx III (Legacy Tebubio ref. 282TP1969). Potent Nav1.7 blocker (IC50 = 2.5 nM). Also inhibits Nav1.1, Nav1.2, Nav1.3 and Nav1.6 in the nanomolar range. Exhibits no effects on Cav channels or nAChR at 5 μM. Demonstrates analgesic activity in vivo; antagonizes effects of scorpion-venom toxin OD1 at Nav1.7.

Prosaptide TX14(A) (Legacy Tebubio ref. 282TP1970). Potent GPR37L1 and GPR37 agonist (EC50 values are 5 and 7 nM, respectively). Stimulates signaling through pertussis toxin-sensitive G proteins. Stimulates ERK phosphorylation. Protects against cellular stress. Promotes myelin lipid synthesis and prolongs cell survival in both Schwann cells and oligodendrocytes; neuroprotective and glioprotective.

Prosaptide TX14(A) acetate (Legacy Tebubio ref. 282TP1970L). Prosaptide TX14(A) acetate is a potent GPR37L1 and GPR37 agonist. Prosaptide Tx14(A) TFA increases both ERK1 and ERK2 phosphorylation in Schwann cells.

Pseudo RACK1 (Legacy Tebubio ref. 282TP1971). Activator of protein kinase C; attached to cell permeabilization Antennapedia domain vector peptide. Consists of peptide derived from the C2 domain of PKC β linked by a disulfide bridge to the Antennapedia domain vector peptide. The Antennapedia peptide is actively taken up by intact cells, at 4 or 37°C, ensuring rapid and effective uptake of the activator peptide. Once inside the cell, the disulfide bonds are subjected to reduction in the cytoplasm leading to release of the activator peptide.

OD1 (Legacy Tebubio ref. 282TP1972). Potent rat Nav1.7, human Nav1.4 and rat Nav1.6 channel activator (EC50 values are 7, 10 and 47 nM, respectively). Exhibits minimal activation at mammalian Nav1.2, Nav1.3 and Nav1.5 (EC50 values >3 μM). Inhibits fast inactivation on all channels. Increases peak currents at all voltages and stimulates a persistent Na+ current at hNav1.7 channel. Increases hyperpolarization at Nav1.4 and Nav1.6 channels. Induces spontaneous pain in vivo.

OXA(17-33) (Legacy Tebubio ref. 282TP1973). Potent and selective peptide orexin OX1 receptor agonist (EC50 values are 8.29 and 187 nM for OX1 and OX2 receptors respectively). Truncated form of orexin A.
