Methylecgonine cinnamate is a natural tropane alkaloid found within the coca plant.[1] Its more common name, cinnamoylcocaine, reflects its close structural similarity to cocaine. It is said to be pharmacologically inactive.[2] But some studies funded by anti-drug agencies imply that it is active when smoked.[citation needed] Furthermore, the discovery of differing impurity products yielding methylecgonine cinnamate in confiscated cocaine have led enforcing agencies to postulate that illicit manufacturers have changed their oxidation procedures when refining cocaine from a crude form.[3] Methylecgonine cinnamate can dimerize to the truxillic acid derivative truxilline.[2] It is notable that methylecgonine cinnamate is given in patents of active cocaine analogue structures.[4][5]
