Insights on the Antioxidant Potential of 1, 2, 4-Triazoles: Synthesis, Screening & QSAR Studies

Abstract

The aligned manuscript reports synthesis, screening and QSAR analysis of twenty six 1, 2, 4-triazole analogues from their respective aromatic carboxylic acids. The structures of synthesized analogues were characterized using physical and spectral analysis. 1, 2, 4-Triazole analogs antioxidant capacity was determined using DPPH radical scavenging assay. Results revealed that out of L, T & VRT series, VRT series of 1, 2, 4-triazoles have significant antioxidant activities when compared with standard ascorbic acid. To obtain structural insights for development of new antioxidants a 2D-QSAR analysis of this dataset of 26 molecules was performed. The 2D-QSAR models correlate with the in vitro results and explain the salient structural features predominant in the molecules responsible for antioxidant activity.
