Synthesis and antioxidant evaluation of novel indole-3-acetic acid analogues

pH-sensitive biopolymeric hydrogel-based on indole-3-acetic acid for wound healing and anti-cancer applications

“…The NCHs have shown higher antioxidant activity than ICD hydrogel due to the presence of AuNPs [61]. The scavenging property of DPPH radical of parent hydrogel (ICD) at various concentration (100, 200, 300, 400 and 500 μg) showed 10,15,19,24 and 29% and NCHs about 36,42,58,60 and 63% for G 1 ICD, 38, 44, 60, 62 and 65% for G 2 ICD respectively. Similarly, the NO radical scavenging ability results of ICD (3, 5, 10, 15 and 20%), G 1 ICD (36,44,46,50 and 59%) and G 2 ICD (36,45,48,52 and 61%) with the same concentration of the sample.…”

“…The parent hydrogel and NCHs having antioxidant property contributed by -NH group attached in these compounds [60], which has represented in (Fig. 12a, b).…”

5H-Dibenz[b,f]azepine based pyrazole sulphonamides: A privileged platform for probing the antimicrobial and antioxidative properties

“…Internal standard, BHA and the synthesized compounds of different concentrations were prepared in distilled ethanol. 1 mL of Each compound solutions having different concentrations (10,25,50, 100, 200 and 500 µM) were taken in different test tubes and 4 mL of 0.1 mM ethanol solution of 1,1-diphenyl-2-picrylhydrazyl (DPPH) was added and shaken vigorously. The tubes were then incubated in the dark room at room temperature for 20 min.…”

“…The literature survey approaching towards synthesis of sulphonamide linked pyrazole gathered with 5H-dibenz[b,f]azepine moiety indicates the lack of reference available. In view of these observation and in persistence of our earlier work on different bioactive heterocyclic derivatives [22][23][24][25][26], we envision our approach towards gathering two bioactive entities, 5H-dibenz[b,f]azepine and pyrazole sulphonamide in one compact structure for probing the antimicrobial and antioxidant potentials.…”

Synthesis, antibacterial, antielastase, antiurease and antioxidant activities of new methoxy substitued bis-1,2,4-triazole derivatives

“…IC 50 values, scavenging abilities on DDPH radicals, were significantly different (p < 0.05) from the IC 50 values obtained for BHT. The presence of electrone donating methoxy substituent in the phenolic compounds is known to increase the stability of the free radical and hence the antioxidant activity 25 . Thus, the compound 6b bearing a methoxy group (electron donating group) showed high DPPH activity.…”
