Naphthoylindoles: Any compound containing a 3-(1-naphthoyl)indole structure with substitution at the nitrogen atom of the indole ring by an alkyl, haloalkyl, alkenyl, cycloalkylmethyl, cycloalkylethyl, 1-(N-methyl-2-piperidinyl)methyl, or 2-(4-morpholinyl)ethyl group, whether or not further substituted in the indole ring to any extent and whether or not substituted in the naphthyl ring to any ...
5,7-Dihydroxy-6-methoxy-2(4-phenoxyphenyl)-4H-chromene-4-one (DMPC) is a derivative of oroxylin A. It has memory improving effects and can reduce ADHD-like behavior. It has memory improving effects and can reduce ADHD-like behavior.
6-MeO-THH, or 6-methoxy-1,2,3,4-tetrahydroharman, is a β-carboline (or more specifically a pinoline) derivative and a structural isomer of tetrahydroharmine (7-MeO-THH). 6-MeO-THH is mentioned in Alexander Shulgin's book TiHKAL (Tryptamines I Have Known and Loved), stating that 6-MeO-THH is very similar to the other carbolines. [1]
The Ehrlich reagent is similar to a number of other indole tests: The van Urk reagent, which uses 0.125 g of p-DMAB, 0.2 mL of ferric chloride solution (25 mg/mL) in 100 mL of 65% sulfuric acid. [9] [10] [11] This is sometimes referred to as the Hofmann reagent or p-DMAB-TS (Test Solution) and gives slightly different colours with different ...
The Nenitzescu indole synthesis. This reaction was named for its discoverer, Costin Nenițescu, who first reported it in 1929. [1] It can be performed with a number of different combinations of R-groups, which include methyl, methoxy, ethyl, propyl, and H substituents. [2]
Indole test positive: appearance of pink layer at top (e.g. Escherichia coli) Like many biochemical tests on bacteria, results of an indole test are indicated by a change in color following a reaction with an added reagent. Pure bacterial culture must be grown in sterile tryptophan or peptone broth for 24–48 hours before performing the test.
The ensuing reaction results in the cleavage of the ether or the ester into an alkyl iodide and respectively an alcohol or a carboxylic acid. Zeisel determination By heating this mixture, the gases are allowed to come into contact with a piece of paper higher up the test tube saturated with silver nitrate .
Its IUPAC name is 6-methoxy-1,2,3,4-tetrahydro-β-carboline, usually abbreviated as 6-MeO-THBC, and its more common name is a combination of "pineal beta-carboline". [2] The biological activity of this molecule is of interest as a potential free radical scavenger, also known as an antioxidant , [ 3 ] and as a monoamine oxidase A inhibitor.
