Benzoylecgonine (BZ) and ecgonine methyl ester (EME) are the most abundant metabolites of over 11 metabolites of cocaine as shown in Fig. 17.1 [10-13]. Cocaine is deactivated to BZ and EME primarily through deesterification (hydrolysis) in the liver. Most other metabolites are pharmacologically inactive or have very low activity. Norcocaine (NC), through an oxidative metabolism, is one of the few metabolites that are pharmacologically active. NC undergoes further metabolism to norcocaine. Anhydroecgonine methyl ester (AEME) results from cocaine pyrolysis and can be used as a marker for crack cocaine use. Depending on the biological matrix examined, the amount of parent drug (cocaine) varies. The major analytes detected in various biological matrices are summarized in Table 2.2

A method for the determination of cocaine (COC), benzoylecgonine (BE), ecgonine methyl ester (EME), and ecgonine (ECG) in plasma by liquid chromatography-mass spectrometry (LC-MS-MS) was developed. The analytes were isolated from human plasma by subsequent solid-phase extraction and were separated o The unsubstituted double bond was selectively reduced using Wilkinson catalyst to provide N-protected anhydroecgonine methyl ester ((R / S)- 4). Following deprotection of N8 nitrogen with TBAF and reductive methylation with formaldehyde and sodium cyanoborohydride, (R / S)- 5 was obtained in overall good yield Ecgonin ist ein Tropan-Alkaloid und findet sich natürlich vorkommend in den Blättern des Cocastrauchs.

A study of the metabolism of in vivo cocaine (COC) and the stability of in vitro COC suggests that the presence of benzoylecgonine (BE) in unpreserved blood arises from in vivo COC metabolism and that ecgonine methyl ester (EME) in unpreserved blood arises from in vitro COC hydrolysis. Postmortem cases positive for COC were studied to determine if molar concentrations of EME in unpreserved blood could be used to estimate the blood COC concentration at the time of death when added to the. The two major urinary metabolites of cocaine are benzoylecgonine (BE) and ecgonine methyl ester (EME). The major advantage of BE screening is that many commercial immunoassays are designed to detect BE. On the other hand, EME is more amenable to gas chromatographic screening. To ascertain the merits of screening BE versus EME for identifying cocaine use, 380 consecutive urine specimens presented to the Office of the Chief Medical Examiner-State of Maryland were tested for BE by EMIT (cutoff.
