Abstract
Histone deacetylase inhibition provides a target for identifying potential antiprotozoal compounds. Histone deacetylase inhibitors are useful as therapeutic agents against protozoal infections.
Claims3
A method for identifying compounds that are antiprotozoal agents by determining whether a test compound or natural product extract inhibits the action of protozoal histone deacetylase, said method comprising:
- (a) contacting a protozoal histone deacetylase, or an extract containing protozoal histone deacetylase with a known amount of a labeled compound that interacts with a protozoal histone deacetylase;
- in the presence or absence of a known dilution of a test compound or a natural product extract;
- and
- (b) quantitating the percent inhibition of interaction of said labeled compound by the difference in the enzyme activities in the presence and absence of the inhibitor test compound or natural product extract.
