Biological Activity of Cinnamoylcocaine

In vitro

Possibilities for discrimination between chewing of coca leaves and abuse of cocaine by hair analysis including hygrine, cuscohygrine, cinnamoylcocaine and cocaine metabolite/cocaine ratios.[Pubmed: 25138383]

Int J Legal Med. 2015 Jan;129(1):69-84.

Contrary to the illegal use of any form of manufactured cocaine, chewing of coca leaves and drinking of coca tea are allowed and are very common and socially integrated in several South American countries. Because of this different legal state, an analytical method for discrimination between use of coca leaves and abuse of processed cocaine preparations is required.
METHODS AND RESULTS:
In this study, the applicability of hair analysis for this purpose was examined. Hair samples from 26 Argentinean coca chewers and 22 German cocaine users were analysed for cocaine (COC), norcocaine (NC), benzoylecgonine (BE), ecgonine methyl ester (EME), cocaethylene (CE), Cinnamoylcocaine (CIN), tropacocaine (TRO), cuscohygrine (CUS) and hygrine (HYG) by hydrophilic interaction liquid chromatography (HILIC) in combination with triplequad mass spectrometry (MS/MS) and hybrid quadrupole time-of-flight mass spectrometry (QTOF-MS). The following concentrations (range, median, ng/mg) were determined in hair of the coca chewers: COC 0.085-75.5, 17.0; NC 0.03-1.15, 0.12; BE 0.046-35.5, 6.1; EME 0.014-6.0, 0.66; CE 0.00-13.8, 0.38; CIN 0.005-16.8, 0.79; TRO 0.02-0.16, 0.023; CUS 0.026-26.7, 0.31. In lack of a reference substance, only qualitative data were obtained for HYG, and two metabolites of CUS were detected which were not found in hair of the cocaine users. For interpretation, the concentrations of the metabolites and of the coca alkaloids in relation to cocaine were statistically compared between coca chewers and cocaine users. By analysis of variance (ANOVA) significant differences were found for all analytes (α = 0.000 to 0.030) with the exception of TRO (α = 0.218). The ratios CUS/COC, CIN/COC and EME/COC appeared to be the most suitable criteria for discrimination between both groups with the means and medians 5-fold to 10-fold higher for coca chewers and a low overlap of the ranges between both groups. The same was qualitatively found for HYG. However, these criteria cannot exclude cocaine use in addition to coca chewing. In this regard screening for typical cutting agents can be helpful and led to the detection of levamisole (21×), lidocaine (6×) and paracetamol (3×) in the 22 samples from German cocaine users, whereas no levamisole, lidocaine (3×) and paracetamol (1×) were found in hair from the Argentinean coca chewers.
CONCLUSIONS:
These criteria have to be confirmed for South American cocaine consumers including smokers of coca paste and may be different because of different composition of the drug and other use habits.

Protocol of Cinnamoylcocaine

Structure Identification
J Forensic Sci. 2007 Jul;52(4):860-6.

Four new illicit cocaine impurities from the oxidation of crude cocaine base: formation and characterization of the diastereomeric 2,3-dihydroxy-3-phenylpropionylecgonine methyl esters from cis- and trans-cinnamoylcocaine.[Pubmed: 17553089]


METHODS AND RESULTS:
Four diastereomeric diols formed from the oxidation of cis- and trans-Cinnamoylcocaine were characterized by nuclear magnetic resonance spectrometry, mass spectrometry, and synthesis. Oxidation of cis-Cinnamoylcocaine in neutral conditions yielded (2R,3R)-dihydroxy-3-phenylpropionylecgonine methyl ester and (2S,3S)-dihydroxy-3-phenylpropionylecgonine methyl ester, while trans-Cinnamoylcocaine produced (2R,3S)-dihydroxy-3-phenylpropionylecgonine methyl ester and (2S,3R)-dihydroxy-3-phenylpropionylecgonine methyl ester.
CONCLUSIONS:
The recent appearance of these new impurities suggests that some illicit cocaine processors have modified their oxidation procedures of crude cocaine base for transformation into illicit refined cocaine hydrochloride.

Four new illicit cocaine impurities from the oxidation of crude cocaine base: formation and characterization of the diastereomeric 2,3-dihydroxy-3-phenylpropionylecgonine methyl esters from cis- and trans-cinnamoylcocaine.[Pubmed:17553089]

J Forensic Sci. 2007 Jul;52(4):860-6.

Four new impurities have recently been detected in the gas chromatographic signature profiles of many illicit cocaine hydrochloride exhibits. These impurities are only seen in exhibits that have been oxidized and are most prominent in samples that have been highly oxidized. Exhibits containing these compounds were subjected to gas and liquid chromatographic-mass spectrometric analyses to determine the identity of the impurities. These impurities were subsequently synthesized to verify their structures. Four diastereomeric diols formed from the oxidation of cis- and trans-Cinnamoylcocaine were characterized by nuclear magnetic resonance spectrometry, mass spectrometry, and synthesis. Oxidation of cis-Cinnamoylcocaine in neutral conditions yielded (2R,3R)-dihydroxy-3-phenylpropionylecgonine methyl ester and (2S,3S)-dihydroxy-3-phenylpropionylecgonine methyl ester, while trans-Cinnamoylcocaine produced (2R,3S)-dihydroxy-3-phenylpropionylecgonine methyl ester and (2S,3R)-dihydroxy-3-phenylpropionylecgonine methyl ester. The recent appearance of these new impurities suggests that some illicit cocaine processors have modified their oxidation procedures of crude cocaine base for transformation into illicit refined cocaine hydrochloride.
