STS-135 (drug)
STS-135 (N-(adamantan-1-yl)-1-(5-fluoropentyl)-1H-indole-3-carboxamide, also called 5F-APICA and ACBM-2201) is a designer drug offered by online vendors as a cannabimimetic agent. The structure of STS-135 appears to use an understanding of structure-activity relationships within the indole class of cannabimimetics, although its design origins are unclear.
