Experimental muscarinic drug
NS-136 is a selective muscarinic acetylcholine M4 receptor positive allosteric modulator which is under development for the treatment of schizophrenia and Alzheimer's disease.[1][3][2] It has been found to possess pro-cognitive effects in rodents.[2] The drug is under development by NeuShen Therapeutics.[1][3] As of May 2024, it is in phase 1 clinical trials for schizophrenia and is in the preclinical stage of development for Alzheimer's disease.[1][3] The drug is a small molecule, but its chemical structure does not seem to have been disclosed.[1][3]
