Design, Synthesis, and Herbicidal Activity of Novel Diphenyl Ether Derivatives Containing Fast Degrading Tetrahydrophthalimide

To seek new protoporphyrinogen oxidase (PPO) inhibitors with better biological activity, a series of novel diphenyl ether derivatives containing tetrahydrophthalimide were designed based on the principle of substructure splicing and bioisomerization. PPO inhibition experiments exhibited that 6c is the most potential compound, with the half-maximal inhibitory concentration (IC50) value of 0.00667 mg/L, showing 7 times higher activity than Oxyfluorfen (IC50 = 0.0426 mg/L) against maize PPO and similar herbicidal activities to Oxyfluorfen in weeding experiments in greenhouses and field weeding experiments. In view of the inspected bioactivities, the structure-activity relationship (SAR) of this series of compounds was also discussed. Crop selection experiments demonstrate that compound 6c is safe for soybeans, maize, rice, peanuts, and cotton at a dose of 300 g ai/ha. Accumulation analysis experiments showed that the accumulation of 6c in some crops (soybeans, peanuts, and cotton) was significantly lower than Oxyfluorfen. Current work suggests that compound 6c may be developed as a new herbicide candidate in fields.

Method for synthesizing 1-cyclohexene-1, 2-dicarboximide

The invention discloses a method for synthesizing 1-cyclohexene-1, 2-dicarboximide. The method comprises that phthalimide and hydrogen as raw materials undergo a reaction in the presence of a catalystto produce 1-cyclohexene-1, 2-dicarboximide at a high yield. The method improves the process conditions, prevents side reaction and realizes high selectivity and a high conversion rate of the reaction. Through simple distillation and crystallization filtration of the reaction liquid, the product with the mass fraction of 98% or more is obtained. Through use of palladium carbon with a mass fraction of 5% and a dry mass of 60% as a catalyst in the catalytic reaction, a low temperature reaction is realized and the reaction conversion rate reaches 93% or more.

Succinimide and maleimide derivatives and their use as topoisomerase II catalytic inhibitors

Maleimide and succinimide derivatives were found to be effective topoisomerase II catalytic inhibitors. Due to this property, the maleimide and succinimide derivatives were investigated for their use as cytostatic agents and thus in the treatment of cancer. The compounds of the invention can be used in combination treatments with other cytostatic agents, such as topoisomerase II poisons. The maleimide and succinimide derivatives, due to their effective topoisomerase II catalytic inhibitory activity, are also useful as extravasation agents, such as upon administration of a topoisomerase II poison.
