Dimethoxytrityl, often abbreviated DMT, is a protecting group widely used for protection of the 5'-hydroxy group in nucleosides, particularly in oligonucleotide synthesis. [ 1 ] It is usually bound to a molecule, but can exist as a stable cation in solution, where it appears bright orange.
6-MeO-DMT, or 6-methoxy-N,N-dimethyltryptamine, also known as 6-OMe-DMT, is a serotonergic drug of the tryptamine family. [ 1 ] [ 2 ] It is the 6- methoxy derivative of the serotonergic psychedelic N , N -dimethyltryptamine (DMT) and is a positional isomer of the serotonergic psychedelic 5-MeO-DMT .
Prominent reactions of metal hydroxides are their acid-base behavior. Protonation of metal hydroxides gives aquo complexes: L n M−OH + H + ⇌ L n M−OH + 2 where L n is the ligand complement on the metal M. Thus, aquo ligand is a weak acid, of comparable strength to acetic acid (pK a of about 4.8). [6] In principle but not very commonly ...
In chemistry, metal hydroxides are a family of compounds of the form M n+ (OH) n, where M is a metal. They consist of hydroxide (OH −) anions and metallic cations, [1] and are often strong bases. Some metal hydroxides, such as alkali metal hydroxides, ionize completely when dissolved. Certain metal hydroxides are weak electrolytes and ...
N,N-Dimethyltryptamine (DMT or N,N-DMT) is a substituted tryptamine that occurs in many plants and animals, including humans, and which is both a derivative and a structural analog of tryptamine. [1] [2] [3] DMT is used as a psychedelic drug and prepared by various cultures for ritual purposes as an entheogen. [9]
The DMT group is removed with a solution of an acid, such as 2% trichloroacetic acid (TCA) or 3% dichloroacetic acid (DCA), in an inert solvent (dichloromethane or toluene). The orange-colored DMT cation formed is washed out; the step results in the solid support-bound oligonucleotide precursor bearing a free 5'-terminal hydroxyl group.
5-MeO-DMT is lipophilic and is thought to easily cross the blood–brain barrier. [2] Accordingly, 5-MeO-DMT readily accumulates in the brain in animals with levels higher than in blood. [2] This is in notable contrast to bufotenin (5-HO-DMT or N,N-dimethylserotonin) and serotonin (5-HT), which are hydrophilic and peripherally selective. [2 ...
DMT can also be made by a different route, namely direct esterification of terephthalic acid with methanol. The dimethyl terephthalate that is formed is then purified by distillation. Even terephthalic acid of low purity may be used in this method. C 8 H 6 O 4 + 2CH 3 OH → C 10 H 10 O 4 + 2 H 2 O. in the presence of o-xylene at 250–300 °C.
