Herein, we report design, one pot synthesis and antibacterial evaluation of novel imidazopyridine bearing pyran bis-heterocycles. The compounds were synthesized in an aqueous solution of gluconic acid under both conventional heating and ultrasound irradiation. The target compounds were obtained in good to moderate yields with yield of 65–88% in 20–60 min under ultrasonic irradiation. The compounds were characterized by spectroscopic methods IR, 1H NMR, 13C NMR, MS and HRMS. X-ray single crystal structure of 7i was also determined. The compounds were evaluated for antibacterial activity by measuring zone of inhibition using disk diffusion method that revealed that some compounds were inhibiting the growth of Gram +ve and Gram -ve bacteria. Result of minimum inhibitory concentration (MIC) showed that 7a, 7h & 7k from a series 7a-7k inhibited the growth of S. aureus. The minimum bactericidal concentration (MBC) value was determined for 7a, 7h & 7k. MBC/MIC ratio of the derivatives 7a, 7k & 7h suggest former two derivatives act as bactericidal agent & later act as bacteriostatic agents against Gram +ve bacteria. Haemolysis results showed that compounds are non-cytotoxic to erythrocytes.

Five new series of imidazo[1,2-a]pyridines carrying biologically active pyrazoline (4a-e), cyanopyridone (5a, b), cyanopyridine (6a-f), 2-aminopyrimidine (7a-f) and pyrimidine-2-thione (8a-d) systems were designed and synthesized as prominent anticonvulsant agents. The target compounds were screened for their in vivo anticonvulsant activity following maximal electroshock (MES) and subcutaneous pentylene tetrazole (scPTZ) methods at a small test dose of 10 mg/kg. Further, Rotarod toxicity method was used to study the toxicity profile of selected compounds. Compounds 4b, 5a, 5b, 6a, 7e and 8d possessing 4-fluorophenyl substituent at 2nd position of imidazo[1,2-a]pyridine ring displayed potent anticonvulsant activity without displaying any toxicity. Enhanced activity profile was observed for new compounds in PTZ method over MES method.
