Hantzsch reaction: Synthesis and characterization of some new 1,4-dihydropyridine derivatives as potent antimicrobial and antioxidant agents

► Two new series of substituted-1,4-dihydropyridine derivatives were synthesized. ► Compounds were characterized by spectral studies. ► Antimicrobial and anti-oxidant evaluation of synthesized molecules was carried out. ► Toxicity study of the biologically active compounds was also performed.
