A series of three platinum(II) phenanthroimidazoles each containing a protonable side-chain appended from the phenyl moiety through copper(I)-catalyzed azide-alkyne cycloaddition (CuAAC) were evaluated for their capacities to bind to human telomere, c-Myc, and c-Kit derived G-quadruplexes. The side-chain has been optimized to enable a multivalent binding mode to G-quadruplex motifs, which would potentially result in selective targeting. Molecular modeling, high-throughput fluorescence intercalator displacement (HT-FID) assays, and surface plasmon resonance (SPR) studies demonstrate that complex 2 exhibits significantly slower dissociation rates compared to platinum phenanthroimidazoles without side-chains and other reported G-quadruplex binders. Complex 2 showed little cytotoxicity in HeLa and A172 cancer cell lines, consistent with the fact that it does not follow a telomere-targeting pathway. Preliminary mRNA analysis shows that 2 specifically interacts with the ckit promoter region. Overall, this study validates 2 as a useful molecular probe for c-Kit related cancer pathways. Bound to impress: A series of three platinum(II) phenanthroimidazoles each containing a protonable side-chain appended from the phenyl moiety through copper(I)-catalyzed azide-alkyne cycloaddition (CuAAC), was evaluated for their capacity to bind to human telomere, c-Myc, and c-Kit derived G-quadruplexes (see scheme). The presence of the side-chain enables a multivalent binding mode to G-quadruplex motifs. Copyright

Disclosed are a novel pyrimidine derivative compound, a pharmaceutically acceptable salt thereof, a method for preparing the compound and a pharmaceutical use of the compound as an anticancer agent or a therapeutic agent for degenerative brain diseases. Specifically, the novel pyrimidine derivative compound has excellent inhibitory activities against kinase enzymes such as ARK5/NUAK1, ACK1, FLT3, JAK1, JAK2 and JAK2 (V617F) and thus is useful for treating and preventing leukemia, ovarian cancer, breast cancer, non-small cell carcinoma, colorectal cancer, glioma, and brain protein abnormalities such as Alzheimer's disease, progressive supranuclear palsy and frontotemporal dementia, that is, degenerative diseases caused by Tau deposition.

VEGFR-2 plays an essential role in angiogenesis and is a central target for anticancer drug discovery. In order to develop novel VEGFR-2 inhibitors, we designed and synthesized 33 biphenyl amides based on our previously reported lead compound. The biological results indicated that four compounds (18b, 20e, 20h and 20j) are potent VEGFR-2 inhibitors which are comparable to positive control. Compound 18b displayed the most potent VEGFR-2 inhibition with IC50 value of 2.02 nM. Moreover, it exhibited promising antiproliferative activity against MCF-7 and SMMC-7721 cells with IC50 values of 1.47 μM and 5.98 μM, respectively. Molecular docking and 3D-QSAR studies were also carried out. The results indicated that these biphenyl amides could serve as promising leads for further optimization as novel VEGFR-2 inhibitors.
