Paragraph 0036-0040; 0060-0065, (2020/03/25)
The invention provides a method for preparing a carbonyl heterocyclic compound, wherein Lewis base and hydrosilane are used as accelerators and can efficiently enable an ortho-substituted aniline compound to react with normal-pressure CO2 to generate corresponding carbonyl heterocyclic compounds containing different functional groups under mild conditions (100 DEG C, digital). According to the method, normal-pressure CO2 is used as an environmentally-friendly non-toxic carbonylation reagent, and cheap Lewis base and PMHS (industrial silicon waste) are used as accelerators, so that the use of CO, high-pressure CO2 and noble metal catalysts is avoided, the intermediate isocyanate does not need to be purified and separated, the pure product can be obtained only through simple suction filtration and separation after the reaction is finished, and the synthetic method is efficient and universal, is suitable for preparing a series of benzimidazolone, benzoxazolone and benzothiazolone compounds and has high industrial application value.

The present invention relates to a method for synthesizing benzothiazolone-based and 1,3-disubstituted urea-based derivatives through activation of CO2. According to the present invention, an inexpensive and easily-available sulfur-containing metal salt compound is first used as an activation catalyst for CO2, and a reaction raw material and CO2 are converted into a corresponding target compound at a low reaction temperature under a low CO2 pressure; and the method has high atomic economy, can reduce the generation of by-products, meets the standards of environmental friendliness and environmentally friendly chemistry, and is the effective way capable of completely utilizing CO2 as the renewable resource, developing new energy and achieving the beneficial cycle of carbon in nature.

Here we report the discovery of a selective inhibitor of Aurora A, a key regulator of cell division and potential anticancer target. We used the atom category extended ligand overlap score (xLOS), a 3D ligand-based virtual screening method recently developed in our group, to select 437 shape and pharmacophore analogs of reference kinase inhibitors. Biochemical screening uncovered two inhibitor series with scaffolds unprecedented among kinase inhibitors. One of them was successfully optimized by structure-based design to a potent Aurora A inhibitor (IC50 = 2 nM) with very high kinome selectivity for Aurora kinases. This inhibitor locks Aurora A in an inactive conformation and disrupts binding to its activator protein TPX2, which impairs Aurora A localization at the mitotic spindle and induces cell division defects. This phenotype can be rescued by inhibitor-resistant Aurora A mutants. The inhibitor furthermore does not induce Aurora B specific effects in cells.
