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.
