MDPEP / Buy MDPEP / MDPEP for sale . Currently, among new psychoactive substances, cathinone derivatives constitute the biggest group, which are mainly classified into N-alkylated, 3,4-methylenedioxy-N-alkylated, N-pyrrolidinyl, and 3,4-methylenedioxy-N-pyrrolidinyl derivatives. These derivatives are actively being subjected to minor modifications at the alkyl chains or the aromatic ring to create new synthetic cathinones with the goal of circumventing laws. In this review, the new synthetic cathinones that have appeared on the illegal drug market during the period 2014–2017 are highlighted, and their characterization by gas chromatography–mass spectrometry and liquid chromatography–tandem mass spectrometry is presented.
Methods Of MDPEP / Buy MDPEP / MDPEP for sale
Various key words were used to conduct an extensive literature search across a number of databases, specifically for synthetic cathinones that emerged between 2014 and 2017.
Results Of MDPEP / Buy MDPEP / MDPEP for sale
More than 30 new cathinone derivatives were discovered. The preexisting parental compounds for the new derivatives are also referenced, and their mass spectral data are compiled in a table to facilitate their identification by forensic toxicologists.MDPEP / Buy MDPEP / MDPEP for sale
To our knowledge, this is the most current review presenting new synthetic cathinones. Political authorities should take measures to implement and enforce generic scheduling (comprehensive system) laws to control the diversely modified synthetic cathinones. Supplementing the existing databases with new findings can greatly facilitate the efforts of forensic toxicologists.MDPEP / Buy MDPEP / MDPEP for sale
Introduction OF MDPEP / Buy MDPEP / MDPEP for sale
MDPEP / Buy MDPEP / MDPEP for sale is one of the biologically active alkaloids found in the khat shrub (Catha edulis). Due to its psychoactive properties, khat has been known and utilized for ages by the inhabitants of East Africa and the northeastern parts of Arabian Peninsula. In many regions, chewing of freshly collected khat leaves (thus liberating cathinone, which affects the central nervous system) is considered a matter of culture and local tradition [1–4]. Because of their structural similarity to amphetamine, cathinone and its analogs are often denoted as “natural amphetamines”, and the only structural difference between amphetamine and cathinone is the presence of a carbonyl group in the α-position of cathinone’s side chain. Similar to amphetamine, cathinone and its analogs are characterized by stimulating, euphoric, and empathogenic properties [1, 2, 4–6].
Due to their effects on the central nervous system, the first synthetic cathinone derivatives were synthesized for medicinal purposes in the early twentieth century, but they began attracting wider attention around the year 2000. At that time, synthetic cathinones were included in a broader group of psychoactive compounds denoted as “legal drugs” or “designer drugs” [5–8]. Over the course of the past 15 years, cathinone derivatives have gradually become available from so-called smart shops, through the Internet, and from drug paraphernalia stores advertising, for example, “funny items” or “aromas” [9–11]. Synthetic cathinones are most often sold as white or colored crystalline powders, and rather rarely as tablets or capsules. In the past, products containing active ingredients from the cathinone group were advertised as “plant nutrients”, “bath salts”, or “research chemicals”. Nowadays, the same substances are frequently labeled with such names as “conquerors of leeches”, “driver’s charms”, “additives to sand”, and “bidet refreshers”. Quite often, these preparations contain a combination of two or more cathinone derivatives, along with other type(s) of new psychoactive substances, caffeine, lidocaine, or benzocaine .

The structures of the first synthetic cathinones have been continuously modified to this day, so that each year several new derivatives emerge on an illegal designer drug market. Given these circumstances, the identification of these compounds and implementation of a drug library with new structures and their physicochemical and pharmacological characteristics become an analytical challenge equally important for chemists and toxicologists.
The structures of all synthetic cathinones are derived from that of natural cathinone, and they can be considered to be phenylalkylamine derivatives, which structurally resemble the molecule of amphetamine with a carbonyl group in the α-position of the side chain adjacent to the aromatic ring. Nowadays, cathinone derivatives can be divided into four groups. Group 1 includes N-alkyl compounds or those with an alkyl or halogen substituent at any possible position of the aromatic ring (Table 1). The majority of the first synthetic cathinones fall into this group, and they include ethcathinone, ephedrone, mephedrone, flephedrone, buphedrone, and pentedrone. Group 2 includes methylenedioxy-substituted compounds with substituents at any given position of aromatic ring, such as methylone, pentylone, and butylone. In terms of their structure and pharmacological effect, these compounds are quite similar to 3,4-methylenedioxymethamphetamine (MDMA) (Table 2). Cathinones from group 3 (examples given in Table 3) are analogs of natural cathinone with an N-pyrrolidinyl substituent, and these compounds are currently the most frequently encountered in the designer drug market. Compounds which include both methylenedioxyl and N-pyrrolidinyl substituents belong to group 4 synthetic cathinones
