Abstract:
A series of 27 new barbiturates and thiobarbiturates have been synthesized by a convenient multi-component reaction in overall excellent yields (87-96%). All the synthesized compounds were characterized by 1H, 13C NMR, EIMS and elemental analysis (C, H, N and S). Furthermore, all compounds were screened for in vitro antioxidant (DPPH radical scavenging), lipoxygenase, chymotrypsin, α-glucosidase and anti-urease activities. Out of the series, 23 in DPPH, 14 in lipoxygenase, 2 in chymotrypsin have shown appreciable IC50 values.
