Triazines are interesting class of heterocyclic compounds. Various synthetic analogs of symmetric triazines have been prepared and evaluated for many pharmacological activities in different models with desired findings. Some analogs have shown potent pharmacological activity and may be considered as lead molecule for the development of future drugs. This review is an attempt to organize the chemical aspects of 1,3,5 triazine analogs reported till date systematically
