Dibromophenols are a group of bromophenols consisting of one hydroxy group and two bromine atoms bonded to a benzene ring. There are six structural isomers , each with the molecular formula C 6 H 4 Br 2 O, which differ by arrangement of the substituents.
6,6'-Dibromoindigo is an organic compound with the formula (BrC 6 H 3 C(O)CNH) 2. A deep purple solid, the compound is also known as Tyrian purple, a dye of historic significance. Presently, it is only a curiosity, although the related derivative indigo is of industrial significance. It is produced by molluscs of the Muricidae species. [1]
The 5-bromo-L-tryptophan can then undergo two separate reactions. One route involves a second bromination by AetF at position 7 to yield 5,7-dibromo-L-tryptophan. This molecule then goes on to react with AetD, an iron-dependent nitrile synthase, to form an indole-3-carbonitrile derivative.
The compound is based on the indole structure, but the 2-3 bond is saturated. By oxidation/dehydrogenation it can be converted to indole. [1] [2] Indoline can be produced from the reaction of indole, zinc and 85% phosphoric acid. [3] It was used to make Indocaine.
5-Bromo-DMT (5-bromo-N,N-dimethyltryptamine) is a psychedelic brominated indole alkaloid found in the sponges Smenospongia aurea and Smenospongia echina, as well as in Verongula rigida (0.00142% dry weight) alongside 5,6-Dibromo-DMT (0.35% dry weight) and seven other alkaloids.
DBNPA or 2,2-dibromo-3-nitrilopropionamide is a quick-kill biocide that easily hydrolyzes under both acidic and alkaline conditions. It is preferred for its instability in water as it quickly kills and then quickly degrades to form a number of products, depending on the conditions, including ammonia, bromide ions, dibromoacetonitrile, and dibromoacetic acid.

Eosin B is a form of eosin which is a dye compound. [1] [2] There is another form [3] of eosin B dye and its chemical name is 4, 5-dibromo-2, 7dinitro- fluorescein or 4′,5′-dibromo-2′,7′-dinitro-3-oxo-3Hspiro[2-benzofuran-1,9′-xanthene]-3′,6′ diolate. [3]
Later, series of more selective c-Met inhibitors were designed, where an indolin-2-one core (encircled in figure 1) was present in several kinase inhibitors. SU-11274 was evolved by substitution at the 5-position of the indolinone [ 9 ] and by adding a 3,5-dimethyl pyrrole group, PHA-665752 was evolved [ 11 ] – a second-generation inhibitor ...
