DS-1 is a drug from theimidazopyridine family, which is the first drug developed that acts as aGABAA receptorpositive allosteric modulator (PAM) selective for theα4β3δ subtype, which is not targeted by other GABAA receptor PAMs such as thebenzodiazepines or othernonbenzodiazepine drugs. Novel selective drugs such as DS-1 are useful in the study of this receptor subtype.[1][2][3]
