Optimized 5-Membered Heterocycle-Linked Pterins for the Inhibition of Ricin Toxin A
, 2016 The optimization of a series of pterin amides for use as Ricin Toxin A (RTA) inhibitors is reported. On the basis of crystallographic data of a previous furan-linked pterin, various expanded furans were synthesized, linked to the pterin, and tested for ...
