<span class="mw-page-title-main">Substituted tryptamine</span> Class of indoles

Substituted tryptamines, or serotonin analogues, are organic compounds which may be thought of as being derived from tryptamine itself. The molecular structures of all tryptamines contain an indole ring, joined to an amino (NH2) group via an ethyl (−CH2–CH2−) sidechain. In substituted tryptamines, the indole ring, sidechain, and/or amino group are modified by substituting another group for one of the hydrogen (H) atoms.

<i>N</i>-Methyltaurine Chemical compound

N-Methyltaurine is an aminosulfonic acid which is present as a zwitterion in the crystalline state and in polar solvents. In contrast to the widespread taurine, N-methyltaurine has been found in nature only in red algae, where it is formed by methylation of taurine. It is suitable for esterification with long-chain carboxylic acids to taurides (acylaminoethansulfonaten) because of its high polarity and the relatively good solubility of its alkaline earth metal salts, which are also used as mild anionic surfactants.

Dimethylaminoethyl acrylate or DMAEA is an unsaturated carboxylic acid ester having a tertiary amino group. It is a colorless to yellowish, water-miscible liquid with a pungent, amine-like odor. DMAEA is an important acrylic monomer that gives basic properties to copolymers.

S-Bahn Erfurt was a colloquial term for a diesel-powered railway connection that existed from 1976 to 1995 in the Thuringian state capital Erfurt, Germany. The term "S-Bahn" is also occasionally used in popular literature. Other contemporary media used terms such as "suburban traffic at the local transport tariff" to describe it. When the line was introduced in 1976, only the "reversible train service" on this line was highlighted as a special feature. In the Kursbuch tables of Deutsche Reichsbahn, the terms "S-Bahn" or "S-Bahn-Tarif" were not used for this line. Riethschleuder was another colloquial term for the connection.
