The preparation of ester heterocycles mostly uses heteroatoms as nucleophilic sites, which are achieved by intramolecular substitution or addition reactions. Compound: 2-(7-Bromo-1H-indol-3-yl)acetic acid( cas:63352-97-6 ) is researched.COA of Formula: C10H8BrNO2.Luebbe, Claus; Van Pee, Karl Heinz; Salcher, Olga; Lingens, Franz published the article 《The metabolism of tryptophan and 7-chlorotryptophan in Pseudomonas pyrrocinia and Pseudomonas aureofaciens》 about this compound( cas:63352-97-6 ) in Hoppe-Seyler’s Zeitschrift fuer Physiologische Chemie. Keywords: tryptophan chlorotryptophan metabolism Pseudomonas. Let’s learn more about this compound (cas:63352-97-6).

P. pyrrocinia ATCC 15958 and a mutant strain (ACN) of P. aureofaciens ATCC 15926 possess a mechanism for the degradation of the tryptophan side chain. Indole, indole-3-carboxylic acid, indole-3-acetic acid, the corresponding compounds chlorinated or brominated at position 7, indole-3-pyruvate, and 7-chloroindole-3-pyruvate were isolated from bacterial cultures. The chlorinated indole derivatives were isolated after the addition of 7-chloro-DL-tryptophan to cultures of P. pyrrocinia whereas their bromo analogs were found in the culture medium of the mutant strain ACN of P. aureofaciens, grown in the presence of NaBr. Enzymic studies show that tryptophan is transaminated to indole-3-pyruvate, which is transformed to indole-3-acetaldehyde. Dehydrogenation of indole-3-acetaldehyde leads to indole-3-acetic acid, which is further metabolized to indole-3-carboxaldehyde and converted by dehydrogenation to indole-3-carboxylic acid. Indole is formed by the spontaneous decarboxylation of indole-3-carboxylic acid.

Computed Properties of C10H8BrNO2. Aromatic heterocyclic compounds can also be classified according to the number of heteroatoms contained in the heterocycle: single heteroatom, two heteroatoms, three heteroatoms and four heteroatoms. Compound: 2-(7-Bromo-1H-indol-3-yl)acetic acid, is researched, Molecular C10H8BrNO2, CAS is 63352-97-6, about Molecular recognition of indole derivatives by polymers imprinted with indole-3-acetic acid: A QSPR study. Author is Porobic, Ivana; Kontrec, Darko; Soskic, Milan.

Three molecularly imprinted polymers (MIPs) were prepared using the phytohormone indole-3-acetic acid (IAA) as a template mol., 4-vinylpyridine (MIP-1 and MIP-2) or N,N-dimethylaminoethyl methacrylate (MIP-3) as functional monomers, ethylenglycol dimethacrylate as a cross linker and acetonitrile (MIP-1), a methanol-water mixture (MIP-2) or chloroform (MIP-3) as porogens. Retention factors for IAA and 29 indole derivatives were determined by high-performance liquid chromatog., using the molecularly imprinted polymers as stationary phases and acetonitrile as an eluent. High correlations between selectivity factors of above mentioned polymers indicate that their retention mechanisms are basically the same. A quant. structure-property relationships anal. revealed that the presence of the terminal carboxyl group on the 3-side chain plays an essential role in the binding of the indole derivatives to the polymers. The derivatives without the carboxyl group exhibit a drastically lower affinity toward the polymers. Another factor which favors the binding is electronic d. of indole nucleus. Substituents with electro-withdrawing properties enhance the binding, while electro-donating substituents have the opposite effect. The length of the 3-side chain also affects the binding. Indole-3-carboxylic acid having the carboxyl group directly attached to the ring as well as the derivatives whose side chain is longer than that of IAA bind to the polymers with a lower affinity.

In general, if the atoms that make up the ring contain heteroatoms, such rings become heterocycles, and organic compounds containing heterocycles are called heterocyclic compounds. An article called Auxin-binding site in wheat shoots: interactions between indol-3-ylacetic acid and its halogenated derivatives, published in 1985, which mentions a compound: 63352-97-6, Name is 2-(7-Bromo-1H-indol-3-yl)acetic acid, Molecular C10H8BrNO2, Application of 63352-97-6.

The specificity of IAA-binding site from wheat shoots was investigated in an attempt to confirm its receptor function. Several monofluoro-, monochloro-, dichloro-, and monobromo-substituted indol-3-ylacetic acids were allowed to displace 14C-IAA from the binding site. Displacement abilities of these halogenated IAAs were closely related to their activities in wheat coleoptile straight growth biotest. This finding indirectly confirms the physiol. significance of this binding site.

Electric Literature of C10H8BrNO2. Aromatic heterocyclic compounds can also be classified according to the number of heteroatoms contained in the heterocycle: single heteroatom, two heteroatoms, three heteroatoms and four heteroatoms. Compound: 2-(7-Bromo-1H-indol-3-yl)acetic acid, is researched, Molecular C10H8BrNO2, CAS is 63352-97-6, about Growth of Avena coleoptiles and pH drop of protoplast suspensions induced by chlorinated indoleacetic acids. Author is Boettger, Michael; Engvild, Kjeld C.; Soll, H..

Several indoleacetic acids, substituted in the benzene ring, were compared in the Avena straight growth bioassay. 4-Chloroindoleacetic acid (I) [2519-61-1], a naturally occurring plant hormone, was one of the strongest hormones in this bioassay. With an optimum at 10-6 mol/L, it was more active than indoleacetic acid [87-51-4], 2,4-dichlorophenoxyacetic acid [94-75-7], and naphthaleneacetic acid [86-87-3]. 5-Chloro- [1912-45-4] and 6-chloroindoleacetic acid [1912-44-3] are very strong auxins as well. Other derivatives tested have a lower activity. 5,7-Dichloro- [1912-40-9] and 5-hydroxyindoleacetic acid [54-16-0] have very low auxin activity at 10-4 mol/L and may be antiauxins. Some of the derivatives were compared for their effect on pH decline in stem protoplast suspensions of Helianthus annuus and Pisum sativum. The change of pH occurs without a lag period or with only a very short one. Derivatives which are very active in the Avena straight growth assay cause a larger pH decline than indoleacetic acid, while inactive derivatives cause effectively no pH decline.

Formula: C10H8BrNO2. The protonation of heteroatoms in aromatic heterocycles can be divided into two categories: lone pairs of electrons are in the aromatic ring conjugated system; and lone pairs of electrons do not participate. Compound: 2-(7-Bromo-1H-indol-3-yl)acetic acid, is researched, Molecular C10H8BrNO2, CAS is 63352-97-6, about Response of substituted indoleacetic acids in the indolo-α-pyrone fluorescence determination. Author is Boettger, Michael; Engvild, Kjeld C.; Kaiser, Petra.

The fluorescence determination of IAA (using the fluorescence of its α-pyrone derivative) was investigated to study possible interference from 4-chloro-IAA and 5-hydroxy-IAA, which occur naturally. Both compounds showed ∼40% of the fluorescence of IAA after conversion to their α-pyrones. Halogenated IAA showed 0-60% of the fluorescence of IAA. Thus, concentration of IAA cannot be determined in crude extracts in the presence of 4-chloro- or 5-hydroxy-IAA because sep. determinations of each of these compounds are not possible by changing the excitation or fluorescence wave-lengths of the testing equipment.
