- Continuous preparation method of trifluoromethyl butenone derivative
-
The invention discloses a continuous preparation method of a trifluoromethyl butenone derivative. The continuous preparation method is characterized in that a raw material 1 as shown in a structure (I) in a reaction formula and trifluoroacetyl halide serving as a raw material 2 react in a microchannel reactor to prepare the trifluoromethyl butenone derivative as shown in a structure (II). The structure (I) and the structure (II) are as described in the specification. In the structure (I) and the structure (II), R is an electron donating group and can be conjugated with olefin double bonds; R1 and R2 are independently selected from hydrogen, C1-C20 alkyl groups, aryl groups, and substituted aryl groups or silyl groups; and X is halogen and is selected from fluorine, chlorine, bromine and iodine. The method has the advantages of good process universality, good atom economy, high yield, few byproducts, high product purity and the like.

- Fragment-Guided Discovery of Pyrazole Carboxylic Acid Inhibitors of the Kelch-like ECH-Associated Protein 1: Nuclear Factor Erythroid 2 Related Factor 2 (KEAP1:NRF2) Protein-Protein Interaction
-
The NRF2-mediated cytoprotective response is central to cellular homoeostasis, and there is increasing interest in developing small-molecule activators of this pathway as therapeutics for diseases involving chronic oxidative stress. The protein KEAP1, which regulates NRF2, is a key point for pharmacological intervention, and we recently described the use of fragment-based drug discovery to develop a tool compound that directly disrupts the protein-protein interaction between NRF2 and KEAP1. We now present the identification of a second, chemically distinct series of KEAP1 inhibitors, which provided an alternative chemotype for lead optimization. Pharmacophoric information from our original fragment screen was used to identify new hit matter through database searching and to evolve this into a new lead with high target affinity and cell-based activity. We highlight how knowledge obtained from fragment-based approaches can be used to focus additional screening campaigns in order to de-risk projects through the rapid identification of novel chemical series.
