Paragraph 0048; 0062; 0063, (2016/11/24)
The invention discloses a biphenyl amide compound with antitumor activity as well as a preparation method and application thereof. The structural formula of the compound is shown in the specification, wherein in the structural formula, R1 is hydrogen or halogen; R2 is alkoxy with carbon number of 1-4; the terminal of R2 is replaced by tert-amido; R2 is linked to the para-position of amide via an oxygen atom. The compound has good tumor cell inhibiting activity in vitro and can be used for preparing antitumor drugs, especially anti-hepatoma drugs and anti-breast cancer drugs. The preparation method of the biphenyl amide compound, provided by the invention, has the advantages that the raw materials are accessible, the reaction conditions are mild, the reaction process is simple to operate, and the used reagent is cheap.

A series of pyridin-3-yl pyrimidines was synthesized and evaluated for their Bcr-Abl inhibitory and anticancer activity. The preliminary results indicated that some compounds were promising anticancer agents. Compounds A2, A8, and A9 exhibited potent Bcr-Abl inhibitory activity, suggesting that aniline containing halogen substituents might be important for biological activity. Molecular docking was carried out to investigate the binding mode of them with Bcr-Abl. Details of synthesis and SAR studies of these compounds are described. A series of phenylaminopyrimidines was designed and synthesized as potent Bcr-Abl inhibitors. The screening of these rationally designed compounds for antitumor activity had identified three candidate leads which could be further optimized to improve the anticancer activities.
Structure-based design of novel 2-amino-6-phenyl-pyrimido[5′, 4′:5,6]pyrimido[1,2-a]benzimidazol-5(6H)-ones as potent and orally active inhibitors of lymphocyte specific kinase (Lck): Synthesis, SAR, and in vivo anti-inflammatory activity

Lck, or lymphocyte specific kinase, is a cytoplasmic tyrosine kinase of the Src family expressed in T-cells and NK cells. Genetic evidence from knockout mice and human mutations demonstrates that Lck kinase activity is critical for T-cell receptor-mediated signaling, leading to normal T-cell development and activation. A small molecule inhibitor of Lck is expected to be useful in the treatment of T-cell-mediated autoimmune and inflammatory disorders and/or organ transplant rejection. In this paper, we describe the structure-guided design, synthesis, structure-activity relationships, and pharmacological characterization of 2-amino-6-phenylpyrimido[5′,4′:5,6]pyrimido[1,2- a]benzimidazol-5(6H)-ones, a new class of compounds that are potent inhibitors of Lck. The most promising compound of this series, 6-(2,6-dimethylphenyl)-2- ((4-(4-methyl-1-piperazinyl)phenyl)amino)pyrimido[5′,4′:5,6] pyrimido-[1,2-a]benzimidazol-5(6H)-one (25), exhibits potent inhibition of Lck kinase activity. This activity translates into inhibition of in vitro cell-based assays and in vivo models of T-cell activation and arthritis, respectively.
