Summary Thiothinone, also known as βk-MPA, is a stimulant classified as the beta-keto substituted counterpart of methiopropamine. It has gained popularity as a designer drug and has been available for purchase on online platforms. Structurally, Thiothinone resembles methcathinone, except that the phenyl group has been replaced by a thiophene group.Interestingly, Thiothinone has also been identified …
Summary 5-Methylmethiopropamine (5-MMPA), or mephedrene, is a stimulant drug. Unlike mephedrone, it is not a substituted cathinone derivative because it lacks a ketone group at the β position of the aliphatic side chain. Instead, it bears a closer resemblance to substituted amphetamines. This compound was discovered in Germany in June 2020 and has since been …
Summary 5-Methylmethiopropamine, also known as 5-MMPA or mephedrene, is a stimulant substance that represents a ring-substituted variant of methiopropamine. Unlike mephedrone, it is not a substituted cathinone derivative, as it lacks a ketone group at the β position of the aliphatic side chain. Instead, its chemical structure bears a closer resemblance to substituted amphetamines. This …
Summary Thiopropamine is a stimulant substance that is an analogue of amphetamine, featuring replacing the phenyl ring with thiophene. While it shares stimulant properties with amphetamine, its potency is approximately one-third less. Additionally, variations such as the N-methyl and thiophene-3-yl analogues are known to be somewhat more potent but generally remain less powerful than their …
Summary Methiopropamine (MPA) is an organic compound that shares a structural resemblance with methamphetamine. First documented in 1942, this molecule features a thiophene group with an alkyl amine substituent at the 2-position. It entered the public market in the United Kingdom in December 2010, marketed as a “research chemical” or “legal high” and more recently …
