Design and synthesis of novel s-triazine based coumarin, quinoline, morpholine and isoniazid derivatives and their antitubercular and antimicrobial evaluation

This study presents the synthesis of novel s-triazine derivatives. The synthetic route to final s-triazines consists of two nucleophilic substitution reactions of 4-hydroxy benzonitrile and 8-hydroxyquinoline or 8-hydroxy-7-methyl coumarin or isoniazid or morpholine with 2,4,6-trichloro-1,3,5-triazine resulting in 2,4-disubstituted-6-chloro-1,3,5-triazine derivatives to introduce the various amines functionality. The structures of the compounds have been elucidated with the aid of IR, 1H and 13C NMR, mass spectroscopy and elemental analysis. The title compounds have then been investigated for their in vitro antimycobacterial activity against Mycobacterium tuberculosis H37Rv strain by using BACTEC MGIT and Lowenstein-Jensen MIC method and antimicrobial evaluation
