Sigma 2 Receptor Ligand

CM398 is a highly selective, orally active Sigma-2 receptor ligand with a K_i value of 0.43 nM. CM398 ameliorates age-related macular degeneration. CM398 exerts analgesic effects on visceral pain, inflammatory pain and neuropathic pain. CM398 can be used in research related to age-related macular degeneration, neuropathic pain and inflammatory pain.

Sigma-2 Receptor ligand 1 (Compound 7i) is a highly selective Sigma-2 receptor ligand with a K_i value of 40 nM. Sigma-2 Receptor ligand 1 is promising for research of Alzheimer's disease.

MS-377 is a selective and orally active sigma-1 receptor ligand (K_i=73 nM) with weak affinity for sigma-2 receptor (K_i=6900 nM) and no affinity for any other receptors including dopamine, serotonin, PCP site, glutamate, γ-aminobutylic acid, adenosine, adrenergic receptors, etc. (K_i: >10 μM). MS-377 indirectly modulates the NMDA receptor ion-channel complex. MS-377 is a antipsychotic agent. MS-377 inhibits PCP-induced behaviors by inhibition of the increase in dopamine and serotonin release in the rat medial prefrontal cortex. MS-377 can be used for research of schizophrenia.
