Discovery of new S-adenosylmethionine decarboxylase inhibitors for the treatment of Human African Trypanosomiasis (HAT)
摘要:
Modification of the structure of trypanosomal AdoMetDC inhibitor 1 (MDL73811) resulted in the identification of a new inhibitor 7a, which features a methyl substituent at the 8-position. Compound 7a exhibits improved potencies against both the trypanosomal AdoMetDC enzyme and parasites, and better blood brain barrier penetration than 1. (C) 2009 Published by Elsevier Ltd.

Novel mechanism-based inhibitors of S-adenosyl-L-methionine decarboxylase are provided. These compounds of formula (1) inhibit the life cycle of trypanosomes, and are useful to treat subjects infected with African trypanosomes. The invention includes pharmaceutical compositions and methods of using the compounds of formula (1).
