Bisbenoxazines derivatives were synthesized by refluxing substituted bisphenol-C, substituted aniline and formaldehyde in presence of 1,4-dioxane with good yields. All the synthesized compounds were characterized by mass, NMR and IR and also evaluated for antimicrobial activity against four different bacterial and two fungal strains. The compounds 1c, 1h, 1j and 1l has found comparatively good active against all the bacterial strains.

Ketene Dithioacetal

Various ketene dithioacetals of acetoacetanilides were reacted with guanidine nitrate in the presence of base to produce the 2-amino-4-isopropyl-6-alkoxy-N-arylpyrimidine-5-carboxamide derivatives with good yields. All the synthesized compounds were characterized by mass, NMR and IR and also evaluated for antimicrobial activity against five different bacterial and fungal strains. The compounds 4i, 4k and 4l has found comparatively good active against all the bacterial strains.

Objective Investigation

Objective: Investigation, the series of newer 2‐amino-pyridine‐3‐carbonitrile and 2‐amino-4H-pyran‐3‐carbonitrile derivative were synthesized and evaluated antimicrobial activities and antioxidant activity. Methods: Novel synthesized chalcones were further condensation to give 2-amino-3-cyanopyridine and 2-amino-3-cyanopyrans in the presence of malononitrile, pyridine, and ammonia acetate. The product is characterized by conventional and instrumental methods. Pyridine and 4-H-Pyran and their analogs occupy prime position due to their diverse applications. Results: The compounds A3C and B3C exhibited marked zone of inhibition with 30.02±0.02 mm and 29.06±0.01 mm, respectively. Docking studies suggested possible interactions with dihydrofolic reductase 4 with 9.15 and −9.67 kcal/mol, respectively. The IC50 30.28±0.01 exhibited A3C by 2,2-diphenylpicrylhydrazyl methods which is better among the series. The 2-amino-3-cyanopyridine derivatives were found good activity than 2-amino-3-cyanopyrane derivative. Among all synthesized compounds few having potent activity and some are near to the standard. Conclusion: Antimicrobial activity and antioxidant of the newly synthesized pyrans and pyridines derivatives will definitely inspire future researchers for the preparation of new analogs.
