LS-115509 is an opioid analgesic related to the 4-phenylpiperidine family. It is comparable to drugs such as prodine and pheneridine, but is distinguished by the presence of an ether group and furan ring at the piperidine 4-position, which are not found in other drugs of this class. In animal studies, it has around 2-3x the potency of morphine depending on what assay is used. Like prodine, it has two stereocenters and four possible enantiomers, but the activity of these has not been tested separately.[1][2][3]
