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 proinflamma...
It has been reported that sulfinamide anhydride is formed when anthranilic acid is treated with thionyl chloride under anhydrous conditions. Garin et al. reported that no sulfinamide anhydride was formed in the reaction of anthranilic acid with thionyl chloride. They reported that 2-(sulfinylamino) benzoyl chloride was formed, in accordance with an earlier observation, under the same reaction c...
In the previous studies, the cytotoxicities of anthranilate sulfonamides were investigated. Herein, the bioactivities of 4-substituted (X = NO2, OCH3, CH3, Cl) benzenesulfonamides of anthranilic acid (5-8) are reported. The results revealed that all sulfonamides selectively exerted antifungal activity (25-50 % inhibition) against C. albicans at 4 μg/mL. Furthermore, compounds 6 and 8 show antio...
Hepatotoxicity is one of the common side effects of nonsteroidal anti-inflammatory drugs (NSAIDs). We investigated the cytotoxicity of 18 acidic NSAIDs (3 salicylic acids, 3 anthranilic acids, 6 arylacetic acids, 6 arylpropionic acids) to freshly isolated rat hepatocytes as assessed by the NSAID-induced leakage of lactate dehydrogenase (LDH) in order to determine structural requirements for the...
A new approach for the synthesis of 4-oxo-3-quinolinecarboxylic acid derivatives is described. This methodology involves the C-acylation of the anions of appropriate beta-keto esters with novel N-hydroxysuccinimide esters of anthranilic acids. The intermediate C-acylation products 3 are spontaneously cyclized to afford 3-ethoxycarbonyl-4-oxoquinoline derivatives 4. The introduction of a variety...
Two novel cyclodepsipeptides containing an unusual anthranilic acid dimer and a D-phenyllactic acid residues, clavatustides A and B, were identified from cultured mycelia and broth of Aspergillus clavatus C2WU isolated from Xenograpsus testudinatus, which lives at extreme, toxic habitat around the sulphur-rich hydrothermal vents in Taiwan Kueishantao. This is the first example of cyclopeptides ...
Abstract Background Metal complexes Cu[C 13 H 8 O 4 N] 2 2, Ni[C l3 3, and Co[C of bioinorganic relevance have been synthesized with the Schiff base ligand 2-furylglyoxal–anthranilic acid (FGAA) [C 9 1 . All are well characterized by various spectral physical methods. The antimicrobial activity has studied against some pathogenic bacteria fungi. Results indicate that higher than free ligand. Th...
