(R)-Emtricitabine sulfoxide is a stereoisomer of oxidized Emtricitabine in which the sulfur atom forms a sulfoxide (S=O) and has an R-configuration. This configuration refers to the spatial arrangement around the sulfur chiral center. It is one of the diastereomers formed during metabolism and generally has lower activity than the parent drug.
