SL-164

SL-164, also known as dicloqualone or DCQ, is an analogue of methaqualone developed in the late 1960s by a team at Sumitomo.^[1] SL-164 has similar sedative, hypnotic^[2] and properties to the parent compound, but was never marketed for clinical use, due to higher risk of convulsions. Like other 4-substituted analogues, such as methylmethaqualone, SL-164 may cause seizures.^[3]
