SH-I-048A (SH-i-048A) is a benzodiazepine derivative related in structure to compounds such as flubromazepam and meclonazepam. SH-I-048A is described as a non subtype selective superagonist at the benzodiazepine site of GABAA receptors,[1] with a binding affinity of 0.77 nM at the α1 subtype, 0.17 nM at α2, 0.38 nM at α3 and 0.11 nM at α5.[2] It has been used to study the functional differences between the different subtypes of the GABAA receptor.[3][4]
