- Continuous production method of multi-kettle serial triazine herbicide
-
The invention relates to a continuous production method of a multi-kettle serial triazine herbicide. A metered cyanuric chloride solution is pre-cooled and mixed with alkylamine R1 in a mixer to entera first-stage reaction kettle, continuous discharging is conducted, after a heat exchanger is passed, the cyanuric chloride solution is neutralized with alkali in the mixer and enters a first-stage neutralization kettle, after a reaction is completed, the cyanuric chloride solution passes through a continuous water separator and the heat exchanger and is mixed with alkylamine R2 in the mixer to enter a second-stage reaction kettle, the continuous discharging is conducted, after the cyanuric chloride solution passes through the heat exchanger, the cyanuric chloride solution is mixed with the alkali in the mixer to enter a second-stage neutralization kettle, after the neutralization, a aqueous phase is separated by a continuous layerer, a solvent is removed, and drying is conducted to obtain a triazine product. The production method has the advantages of high productivity, good production stability, high efficiency, high product quality and the like, is particularly suitable for technical transformation of existing production enterprises, has a low transformation cost, basically does not add novel reaction equipment, and is easily mastered by existing enterprises.

- Synthesis and structure-activity relationship study of triazine-based inhibitors of the DNA binding of NF-κB
-
Nuclear transcription factor nuclear factor-kappa B (NF-κB) has diverse pathophysiological functions, and NF-κ B inhibitors are considered to be candidates for multiple therapeutic applications. We previously reported a novel triazine-based NF-κB inhibitor, 2-anilino-4,6-dichloro-1,3,5- triazine (NI241), that directly inhibits DNA binding of NF-κB. Here, we report synthesis of a series of triazine derivatives and evaluation of their structure-activity relationships for NF-κB inhibition. We found that 2-amino-4,6-dichloro-1,3,5-triazine substructure is essential for the inhibitory activity of the lead compound NI241, and modification of NI241 by introduction of an m-methoxy substituent on the phenyl ring afforded the more potent derivative 28. The structure-activity relationships identified in this study suggested a possible mechanism of irreversible NF-κB inhibition by NI241, and should be helpful in the design of other NF-κB inhibitors.

- Discovery of triazines as potent, selective and orally active PDE4 inhibitors
-
Expanding on HTS hit 4 afforded a series of [1,3,5]triazine derivatives as novel PDE4 inhibitors. The SAR development and optimization process with the emphasis on ligand efficiency and physicochemical properties led to the discovery of compound 44 as a potent, selective and orally active PDE4 inhibitor.
