Abstract
A number of amidine derivatives ( 2a– i) have been synthesized by condensation of 2-cyanopyridine with various 3,4-diaryl-2-imino-4-thiazolines. Various amide derivatives ( 3a– h) were synthesized by condensation of orotic acid and hydantoin-5-acetic acid with a number of 3,4-diaryl-2-imino-4-thiazolines using microwave irradiation. All the compounds i.e. ( 2a– i) and ( 3a– h) synthesized were characterized by spectroscopic means and elemental analysis. Compounds ( 2a– i) and ( 3a– h) at 50 mg/kg p.o. were screened for anti-inflammatory activity whereas 2a– d, f, g, i and 3a, b, d, f at 50 mg/kg p.o. were evaluated for analgesic activity. Compounds 2e and 3g exhibited good anti-inflammatory activity (49% and 34%, respectively) and 2f, g showed interesting (50% in each case) analgesic activity.
