CS1P1 | CAS#1246526-29-3 | S1PR1-specific ligand

MedKoo Cat#: 465907 | Name: CS1P1

Description:

WARNING: This product is for research use only, not for human or veterinary use.

CS1P1 is a novel S1PR1-specific ligand, binding to S1PR1 in human frontal cortex tissue. [3H]CS1P1 binds to S1PR1 in human frontal cortex tissue with a Kd of 3.98 nM and a Bmax of 172.5 nM. [11C]CS1P1 in a nonhuman primate (NHP) shows a standardized uptake value of 2.4 in the NHP brain, with test-retest variability of 0.23% among six different NHPs. [11C]CS1P1 was stable in vivo. [11C]CS1P1 is a promising radioligand for PET imaging of S1PR1 in the CNS.

More Info

Sphingosine-1-phosphate receptor 1 (S1PR1) is ubiquitously expressed among all tissues and plays key roles in many physiological and cellular processes. In the central nervous system (CNS), S1PR1 is expressed in different types of cells including neurons, astrocytes, and oligodendrocyte precursor cells. S1PR1 has been recognized as a novel therapeutic target in multiple sclerosis and other diseases
