Original Research


The naturally viable α-amino acid surrogates have been synthesised via Kabachnik–Fields reaction by the condensation of 2-aminothiazole with various aldehydes and dialkyl phosphites in the presence of Caffeine hydrogen sulfate (CHS) as eco-friendly and reusable catalyst under microwave irradiation and solvent-free conditions. The title compounds were characterised by IR, 1H, 13C, 31P NMR and mass spectral data. All the synthesised (4aj) compounds were screened for their insilico and in vitro studies. The results revealed that, out of all the titled compounds 4a, 4e, 4h and 4i have exhibited significant activity in terms of antioxidant and anti-inflammatory activity. In addition, molecular docking studies were also carried out against Cox-2 with celocoxib as the standard.
