Ganglioside GQ1b is a tetrasialoganglioside that contains two sialic acid residues linked to an inner galactose unit. It stimulates phosphorylation of several ecto-type protein kinase substrates on the surface of GOTO human neuroblastoma cells when used at a concentration of 5 nM. Ganglioside GQ1b promotes differentiation of murine embryonic stem cells (mESCs) to neuronal precursor and glial cells via activation of the ERK1/2 pathway. It also induces differentiation of murine keratinocytes through phosphoinositide turnover. Ganglioside GQ1b mixture contains ganglioside GQ1b molecular species with C18:1 and C20:1 sphingoid backbones.
TRV056 is a Gq-biased agonist of the angiotensin II type 1 receptor (AT1R), demonstrating efficacy in stimulating Gq-mediated cellular signaling. It can serve as a foundation for the development of Gq-biased AT1R agonists.
TRV055 is a Gq-biased ligand of the angiotensin II receptor type 1 (AT1R). TRV055 is efficacious in stimulating cellular Gq-mediated signaling. TRV055 can be used to develop the Gq-biased AT1R agonists.
K-(D-1-Nal)-FwLL-NH2 TFA is a potent and high-affinity inverse agonist of the ghrelin receptor, exhibiting Ki values of 4.9 nM in COS7 cells and 31 nM in HEK293T cells. This compound effectively inhibits ghrelin receptor-mediated Gq- and G13-dependent signaling pathways.
