Synthesis and antibacterial evaluation of series of novel tri-substituted-s-triazine derivatives
摘要:
Two novel series of s-triazine derivatives (6a-e and 7a-f) were synthesized with various aromatic and heterocyclic amines. The synthesized compounds were subsequently evaluated for their in vitro antibacterial activity against three gram-positive viz. Bacillus subtilis (NCIM-2063), Bacillus cereus (NCIM-2156), Staphylococcus aureus (NCIM-2079) and gram-negative bacteria viz. Pseudomonas aeruginosa (NCIM-2036), Escherichia coli (NCIM-2065) and Klebseilla pneumoniae (NCIM-2706) by the broth dilution method as recommended by the National Committee for Clinical Laboratory Standards (NCCLS) using streptomycin as reference standard. Structures of the synthesized compounds were elucidated on the basis of elemental analyses and spectral data.

Condensation of 5-cyano-2-hydrazino-3-N-methyl-6-phenyl/p-chlorophenyl-3,4-dihydropyrimidin-4-one (3a and 3b) with 2 4-bisalkyl/arylamino-6-chloro-s-triazine (4) gave the corresponding 2,4-bisalkyl/arylamino-6-[5'-cyano-3'-N-methyl]-6'-phenyl/p-chlorophenyl-3',4'-dihydropyrimidin-4'-one-2'-yl-hydrazino-s-triazines (5a-n and 6a-n). The compounds 4 have been prepared by the condensation of cyanuric chloride and different alkyl/aryl amines. The reaction between 5-cyano-3-N-methyl-2-methylthio-6-phenyl/p-chlorophenyl-3,4-dihydropyrimidin-4-one (2a and 2b) with hydrazine hydrate furnished 3a and 3b, respectively. The condensation of 6-phenyl/p-chlorophenyl/5-cyano-2-mercapto-3,4-dihydropyrimidin-4-one (1a and 1b) with methyl iodide yielded 2a and 2b, respectively. All the products have been evaluated in vitro for their antimicrobial activity against several microbes and antitubercular activity against Mycobacterium tuberculosis H37 Rv.
