Synthesis, characterization and evaluation of antidiabetic activity of novel indoline derivatives

Abstract

<p class="Abstract">Series of indoline derivatives were synthesized using N-(4-aminophenyl)indoline-1-carbothiamide as a precursor. The confirmation of synthesized compounds was done by ¹H-NMR, ¹³C-NMR, LC-MS (ESI) and FT-IR. In vitro antidiabetic activity of synthesized indoline derivatives were examined by standard α-amylase inhibition assay. The compounds 4a (IC₅₀= 52.1 µg/mL) and 4b (IC₅₀= 57.7 µg/mL) showed potent α-amylase inhibition activity. The compounds 3a (IC₅₀= 62.2 µg/mL) and 3b (IC₅₀= 60.7 µg/mL) showed moderate antidiabetic activity.</p><p class="Abstract"><strong>Video Clip of Methodology</strong>:</p><p class="Abstract">19 min 21 sec   <a href="https://www.youtube.com/v/k5WdfpM-E8U">Full Screen</a>   <a href="https://www.youtube.com/watch?v=k5WdfpM-E8U">Alternate</a></p>
