Abstract:

Anthranilic acid is a benzenoid compound that has adjacent active important two reactive groups namely carboxylic acid group (-COOH) and amino group (-NH<sub>2</sub>). Consequently fascinating anthranilic acid derivatives have been prepared through both the active functional groups.  The literature review reveals an experiential and holistic approach of various manufacturing procedures and skills used for the production of anthranilic acid analogues and anthranilic scaffold along with the biological activities of some of the promising derived anthranilic acid molecules.  Pharmacology

Abstract:

The anthranilic acid (2), a key intermediate for the generation of an aryne at C13 of podocarpic acid derivatives, was synthesized from the 14-amino compound (5) which in turn was generated regiospecifically in high yield by treatment of the 13-bromo compound (25) with sodamide in liquid ammonia. The amine was converted into the anthranilic acid by two separate routes: firstly by directed lithiation and trapping of the lithium species with a CO2 moiety, and secondly by oxidative cleavage of an isatin fused across positions 13 and 14.

Abstract:

Local catabolism of the amino acid tryptophan (Trp) by indoleamine 2,3-dioxygenase (IDO) is considered an important mechanism of regulating T cell immunity. We show that IDO transcription was increased when myelin-specific T cells were stimulated with tolerogenic altered self-peptides. Catabolites of Trp suppressed proliferation of myelin-specific T cells and inhibited production of proinflammatory T helper–1 (TH1) cytokines.

Abstract:

The gut microbiome provides the host access to otherwise indigestible nutrients, which are often further metabolized by the microbiome into bioactive components. The gut microbiome can also shift the balance of host-produced compounds, which may alter host health. One precursor to bioactive metabolites is the essential aromatic amino acid tryptophan. Tryptophan is mostly shunted into the kynurenine pathway but is also the primary metabolite for serotonin production and the bacterial indole pathway. Balance between tryptophan-derived bioactive metabolites is crucial for neurological homeostasis

Abstract:

Novel spectrophotometric methods were developed for the determination of fenpropathrin in insecticidal formulations and water samples. The methods were based on the hydrolysis of fenpropathrin with ethanolic KOH to form 3-phenoxy benzaldehyde. The resultant aldehyde group was condensed with anthranilic acid in presence of basic medium to form yellowish red color product having λmaxof 485 nm or condensed with 2-chloro phenyl hydrazine to form pink color product having λmaxof 557 nm. The color derivatives were correspondingly stable for 5 and 8 days. The Beer's law was obeyed over the range from

Abstract:

There has been considerable interest in the development of novel compounds with anticonvulsant, antioxidant, antibacterial, and antifungal activities. The present study explores the antimicrobial activity of some new arylidene hydrazide derivatives and correlates the effect on the antimicrobial potency by varying the substituents on hydrazide part of the arylidine hydrazide. Hydrazones possessing an azomethine–NHN=CH- proton constitute an important class of compounds for new drug developments; therefore, a series of arylidene hydrazides were synthesized with various aromatic aldehydes/ketones.

Abstract:

Several new substituted thiadiazole pyrazolene anthranilic acid derivatives were synthesized. These compounds also evaluated for their anti-inflammatory and analgesic activities. Compound 2-((5-(3- (2,6-dichloro)acrylamido)-1,3,4-thiadiazol-2-yl)methyl amino)-benzoic acid (5b) and 2-((5-(1-acetyl- 5-(2,6-dichloro)-4,5-dihydro-1H-pyrazol-3-ylamino)-1,3,4-thiadiazol-2-yl)methyl amino)benzoic acid (6b) were found to be most active compounds of this series, which exhibits 38.10 & 48.50% anti-inflammatory activity while, 36.24 & 40.10 % analgesic activity, respectively.
