Abstract
A new azo-type quaternary pyridinium salt (Azo-QPS) shows enhanced activity at acidic conditions (e.g., pH=5); in neutral or basic conditions, this new Azo-QPS shows a much lower level (2-50 times less) anti-bacterial activity. The use of such a 'stimulus-enhance' antibiotic can response to the proliferation of bacteria directly. It helps reduce or prevent the build-up of potent antibacterial agents in the oral environment. The antibacterial properties of Azo-QPS are 'activated' when the environmental pH becomes acidic; this acidic pH may be indicative of the accumulation ofor the initiation of tooth decay.
