N-Methyldihydroquinazolinone Derivatives of Retro-2 with Enhanced Efficacy against Shiga Toxin
摘要:
The Retro-2 molecule protects cells against Shiga toxins by specifically blocking retrograde transport from early endosomes to the trans-Golgi network A SAR study has been carried out to identify more potent compounds. Cyclization and modifications of Retro-2 led to a compound with roughly 100 fold improvement of the EC50 against Shiga toxin cytotoxicity measured in a cell protein synthesis assay. We also demonstrated that only one enantiomer of the dihydroquinazolinone reported herein is bioactive.

Abstract A new o‐amino benzoic acidderivative, 2‐amino‐N‐phenyl‐benzamide, has been obtained by the reaction of o‐amino benzoic acid and aniline. Twelve new asymmetric Schiff bases, which have both and functional groups containing 2‐amino‐N‐phenyl‐benzamide, have been synthesized and characterized.
