(+)-CPCA

(+)-CPCA (nocaine, 3α-carbomethoxy-4β-(4-chlorophenyl)-N-methylpiperidine) is a stimulant drug similar in structure to pethidine (an opioid that possesses NDRI actions) and to RTI-31, but nocaine is lacking the two-carbon bridge of RTI-31's tropane skeleton This compound was first developed as a substitute agent for cocaine.

Since this time a large number of substituted phenylpiperidine derivatives have been discovered, hybridizing the basic nocaine structure with that of other similar molecules such as methylphenidate, meperidine and modafinil to create a large family of derivatives with a range of activity profiles and potential applications. This is a significant field of research with much work ongoing, and dozens of novel compounds have been developed although none have yet come to market.

The nocaine family includes a diverse assortment of piperidine based cocaine mimics. The parent compound nocaine was developed in an attempt to develop a substitute drug for cocaine for the treatment of addiction, and was found to substitute for cocaine in animal models while having significantly less abuse potential itself.
