5-Bromo-4-phenoxy-N-phenylpyrimidin-2-amine derivatives were synthesized and evaluated as ULK1 inhibitors in non-small cell lung cancer. Among all the obtained ULK1 inhibitors, 5-bromo-4-(2-fluoro-4-nitrophenoxy)-N-(3,4,5-trimethoxyphenyl) pyrimidin-2-amine, was the most active one. The docking anal. was conducted to compare 5-bromo-4-(2-fluoro-4-nitrophenoxy)-N-(3,4,5-trimethoxyphenyl) pyrimidin-2-amine and SBI-0206965, which further elucidated the roles of the H-bond donor. This compound inhibited the proliferation of A549 cells and showed strong inhibitory activity against ULK1 kinase. Moreover, we found that 5-bromo-4-(2-fluoro-4-nitrophenoxy)-N-(3,4,5-trimethoxyphenyl) pyrimidin-2-amine could induce apoptosis while simultaneously blocking autophagy. Collectively, these findings shed new light on 5-bromo-4-(2-fluoro-4-nitrophenoxy)-N-(3,4,5-trimethoxyphenyl) pyrimidin-2-amine that would be utilized as a promising candidate drug for the future NSCLC therapy.

A series of diarylurea inhibitors of the cardiac-specific kinase TNNI3K were developed to elucidate the biol. function of TNNI3K and evaluate TNNI3K as a therapeutic target for the treatment of cardiovascular diseases. Utilizing a structure-based design, enhancements in kinase selectivity were engineered into the series, capitalizing on the established X-ray crystal structures of TNNI3K, VEGFR2, p38α, and B-Raf. Our efforts culminated in the discovery of an in vivo tool compound 47 (GSK329), which exhibited desirable TNNI3K potency and rat pharmacokinetic properties as well as promising kinase selectivity against VEGFR2 (40-fold), p38α (80-fold), and B-Raf (>200-fold).

The article conveys some information:

NUAK, the member of AMPK (AMP-activated protein kinase) family of protein kinases, is phosphorylated and activated by the LKB1 (liver kinase B1) tumor suppressor protein kinase. Recent work has indicated that NUAK1 is a key component of the antioxidant stress response pathway, and the inhibition of NUAK1 will suppress the growth and survival of colorectal tumors. As a promising target for anticancer drugs, few inhibitors of NUAK were developed. With this goal in mind, based on NUAK inhibitor WZ4003, a series of derivatives has been synthesized and evaluated for anticancer activity. Compound I, a derivative of WZ4003 by removing a methoxy group, was found to be the most potential one with stronger inhibitory against NUAK1/2 enzyme activity, tumor cell proliferation and inducing apoptosis of tumor cells. By in vivo efficacy evaluations of colorectal SW480 xenografts, I suppresses tumor growth more effectively with an excellent safety profile in vivo and is therefore seen as a suitable candidate for further investigation. The results came from multiple reactions, including the reaction of 2,4-Dichloropyrimidine(cas: 3934-20-1Quality Control of 2,4-Dichloropyrimidine)

Focal adhesion kinase (FAK) is a ubiquitous intracellular non-receptor tyrosine kinase, which is involved in multiple cellular functions, including cell adhesion, migration, invasion, survival, and angiogenesis. In this study, a series of 7H-pyrrolo[2,3-d]pyrimidines were designed and synthesized according to the E-pharmacophores generated by docking a library of 667 fragments into the ATP pocket of the co-crystal complex of FAK and PF-562271 (PDB ID: 3BZ3). The 5-fluoro-7H-pyrrolo[2,3-d]pyrimidine derivatives demonstrated excellent activity against FAK and the cell lines SMMC7721 and YY8103. 2-((2-((3-(Acetamidomethyl)phenyl)amino)-5-fluoro-7H-pyrrolo[2,3-d]pyrimidin-4-yl)amino)-N-methylbenzamide (I) was selected for further bioactivity evaluations in vivo, including preliminary pharmacokinetic profiling in rats and toxicity assays in mice, and tumor growth inhibition studies in a xenograft tumor model. The results showed that I did not affect the body weight gain of the animals up to a dose of 200 mg/kg, and significantly inhibited tumor growth with a tumor growth inhibition rate of 78.6% compared with the neg. control group. Furthermore, phosphoantibody array analyses of a sample of the tumor suggested that I inhibited the malignant proliferation of hepatocellular carcinoma (HCC) cells through decreasing the phosphorylation in the FAK cascade.

《Coordination Polymers from Functionalized Bipyrimidine Ligands and Silver(I) Salts》 was written by Beaulieu-Houle, Guillaume; White, Nicholas G.; MacLachlan, Mark J.. Formula: C9H6N4O2 And the article was included in Crystal Growth & Design on April 4 ,2018. The article conveys some information:

Readily functionalizable bipyrimidine compounds were prepared for the first time, and their coordination chem. with silver salts was explored. Solution 1H NMR spectroscopy experiments indicated that the ligands rapidly form complexes with silver(I) salts, and coordination at a first site inhibits coordination of a second cation to the ligand, thus favoring 1:1 complexes in solution These 1:1 units self-assemble into one-dimensional chains in the solid state, even in the presence of excess Ag(I). Structurally diverse coordination polymers exhibiting different coordination numbers and geometry were characterized by single crystal X-ray crystallog. Our results demonstrate that a modification to the ligand, distal from the binding site, affects the coordination chem. and supramol. structure of these complexes. The results came from multiple reactions, including the reaction of 2-(Pyrimidin-2-yl)pyrimidine-5-carboxylic acid(cas: 933191-25-4Formula: C9H6N4O2)

Lapatinib, an approved epidermal growth factor receptor inhibitor, was explored as a starting point for the synthesis of new hits against Trypanosoma brucei, the causative agent of human African trypanosomiasis (HAT). Previous work culminated in I, which was part of a series typically associated with poor aqueous solubility In this report, we present various medicinal chem. strategies that were used to increase the aqueous solubility and improve the physicochem. profile without sacrificing antitrypanosomal potency. To rank trypanocidal hits, a new assay (summarized in a cytocidal effective concentration (CEC50)) was established, as part of the lead selection process. Increasing the sp3 carbon content of I resulted in II (0.19 μM EC50 against T. brucei and 990 μM aqueous solubility). Further chem. exploration of II yielded III, a trypanocidal quinolinimine (EC50: 0.013 μM; aqueous solubility: 880 μM; and CEC50: 0.18 μM). Compound III reduced parasitemia 109 fold in trypanosome-infected mice; it is an advanced lead for HAT drug development.
