Synthesis and antimicrobial studies of s-triazine based heterocycles.

In an effort to discover new candidates with improved antimicrobial activities we report here the synthesis and in vitro biological evalution of various series of 2-(N-methylamino)-4-(N,N-dimethylamino)-6-(arylthioureido)-s-triazine (5a-j) and (N-methylamino)-4-(N,N-dimethylamino)-6-(arylureido)-s-triazine (6a-j). All the synthesized compounds were screened in vitro for their antibacterial activity against two different gram-positive bacteria (S. aureus, B. subtilis) and two different gram-negative bacteria (P. aeruginosa, E. coli) using the broth dilution method.
