Discovery of Pyrimidinedione Derivatives Containing Oxime Ester/Carbamate Fragments as Potent Protoporphyrinogen IX Oxidase Inhibitors
To continue our research on developing PPO inhibitors, we replaced the triazinone core of compounds B, G, and H from our previous work with pyrimidinediones, employing a scaffold-hopping strategy to design and synthesize compounds I, J, and K. Compound I18 exhibited potent NtPPO inhibition (Ki = 10.9 nM) and broad-sp...
