Mechanochemistry in action: Exploitation of internal acid catalysis in Solvent-free synthesis of imines and evaluation of radical scavenging activities of imino derivatives
Sarma, Madhushree Das,Ghosh, Subhojit
, p. 345 - 349 (2021/02/02)
Mechanochemical protocol has been exploited to accomplish the synthesis of imino derivatives from aromatic amines with acidic functionalities and different aromatic aldehydes in excellent to nearly quantitative yields. Presence of acidic groups in the aromatic amines has been found to have profound influence on the course of the reaction. The prepared imines were screened for in vitro antioxidant activity using 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical. Some of the prepared imino derivatives displayed good to moderate antioxidant property when compared with standard natural antioxidant (L-ascorbic acid).

An application of ultrasonic irradiation in the one-pot synthesis of N-acetyl-2-aryl-1,2-dihydro-(4H)-3,1-benzoxazin-4-ones from the condensation reaction between aromatic aldehydes and anthranilic acid in the presence of excess amount of acetic anhydride
Synthesis, characterization and biological activity of some novel formazan derivatives
Babu, A. Narendra,Nadendla, Rama Rao
experimental part, p. 1349 - 1352 (2012/01/02)
1-Substituted phenyl-3-substituted phenyl-4-(o-carboxyphenyl) formazans [3a-s] were synthesized by treating azomethines (A1-5) with diazonium salts. Compounds (A1-5) were synthesized by condensing anthranilic acid with various substituted aromatic aldehydes. All the synthesized compounds were characterized by IR, 1H NMR, Mass and elemental analysis and then evaluated for analgesic, antiinflammatory, antibacterial and antifungal activities.
Synthesis of some newer derivatives of 2-amino benzoic acid as potent anti-inflammatory and analgesic agents
Kumar, Ashok,Bansal, Deepti,Bajaj, Kiran,Sharma, Shalabh,Archana,Srivastava
, p. 5281 - 5291 (2007/10/03)
Diazotization of N-benzylidene anthranilic acids 1a-1n at pH 9 yielded N-[α-(phenylazo) benzylidene] anthranilic acids 2a-2n and at pH 3 yielded N-benzylidene-5-(phenylazo) anthranilic acids 3a-3n. When compounds 3a-3n were treated with thioglycolic/thiolactic acid in the presence of anhydrous ZnCl 2, 2-(4-oxo-2-phenylthiazolidin-3-yl)-5-(phenylazo) benzoic acids 4a-4n were afforded. The newly synthesized compounds were screened for their anti-inflammatory and analgesic activities and were compared with standard drugs, aspirin and phenylbutazone. Out of the compounds studied, the most active compound 4n showed more potent activity than the standard drugs at all doses tested.
