What is Design, Synthesis, and Metabolism Studies of N -1,4-Diketophenyltriazinones as Protoporphyrinogen IX Oxidase Inhibitors about?

Protoporphyrinogen IX oxidase (PPO, EC 1.3.3.4) is an established site for green herbicide discovery. In this work, based on structural analysis, we develop an active fragment exchange and link (AFEL) approach to designing a new class of N-1,4diketophenyltriazinones I-III as potent Nicotiana tabacum PPO (PPO) inhibitors. After systematic structure-activity relationship optimizations, a series of new compounds with K i values in the single-digit nanomolar range toward NtPPO and promising herbicidal activity were discovered. Among them, Ii (K i = 0.11 nM) displays 284-and 90-fold improvement in NtPPO inhibitory activity over trifludimoxazin (K i = 31 nM) and saflufenacil (K i = 10 nM), respectively. In addition, Ip (K i = 2.14 nM) not only exhibited good herbicidal activity at 9.375-37.5 g ai/ha but also showed high crop safety to rice at 75 g ai/ha by the postemergence application, indicating that Ip could be developed as a potential herbicide for weed control in rice fields. Additionally, our molecular dynamic simulation clarified the molecular basis for the interactions of these molecules with NtPPO. The metabolism studies in planta showed that IIIc could be converted to Ic, which
