Anti-Oxidant Activity of Novel 5-Substituted Arylidene-3-Substituted- Benzyl-Thiazolidine-2, 4-Diones

A series of 5-substituted-arylidene-3-substituted-benzyl-thiazolidine-2, 4-dione derivatives were synthesized from thaizolidinedione and substituted benzyl chloride followed by the addition of substituted aromatic aldehydes. All the compounds 1(a)-1(e) and 2(a)-2(c) were screened for their in vitro antioxidant activity using DPPH method. The anisaldehyde based thiazolidinedione compounds 1(a) and 2(a) displayed good activity comparable to those of standard.
