DS-1 (drug)

DS-1 is a drug from the imidazopyridine family, which is the first drug developed that acts as a GABA_A receptor positive allosteric modulator (PAM) selective for the α4β3δ subtype, which is not targeted by other GABA_A receptor PAMs such as the benzodiazepines or other nonbenzodiazepine drugs. Novel selective drugs such as DS-1 are useful in the study of this receptor subtype.^[1][2][3]
