Chalcogen OCF3 Isosteres Modulate Drug Properties without Introducing Inherent Liabilities.

abstract：:There is an urgent need for new drugs for the treatment of tropical parasitic diseases such as human African trypanosomiasis, which is caused by Trypanosoma brucei. The enzyme trypanothione reductase (TryR) is a potential drug target within these organisms. Herein we report the screening of a 62,000 compound library a...
