Novel VEGFR-2 kinase inhibitors identified by the back-to-front approach
摘要:
We report a novel VEGFR-2 inhibitor, developed by the back-to-front approach. Docking experiments indicated that the 3-chloromethylphenylurea motif of the lead compound occupied the back pocket of VEGFR-2 kinase. An attempt was made to enhance the binding affinity of 1 by expanding the structure to access the front pocket using a triazole linker. A library of 1,4-(disubstituted)-1H-1,2,3-triazoles were screened in silico, and one compound (VH02) was identified with an IC50 against VEGFR-2 of 0.56 mu M. VH02 showed antiangiogenic effects, inhibiting tube formation in HUVEC cells (EA.hy926) at 0.3 mu M, 13 times lower than its cytotoxic dose. These enzymatic and cellular activities suggest that VH02 has potential as a lead for further optimization. (C) 2013 Elsevier Ltd. All rights reserved.

Click ‘n’ chips: Azide and alkyne‐bearing sialic acids (purple diamond; see picture) were subjected to high‐throughput click chemistry to generate a library of sialic acid analogues. Microarray printing of the library and screening with the siglec family of sialic‐acid‐binding proteins, led to the identification of high‐affinity ligands for siglec‐9 and siglec‐10.
In this study, two series of simplified isoquinolines deriving from lophocladine B were synthesized and evaluated for their antitumor activity. Suzuki-Miyaura and Sharpelss-Fokin reactions were employed to synthesize 26 compounds. Two compounds (25 and 27) showed to be cytotoxic with IC50 values of 10 µM on hepatic cancer cells and 13 µM on cervical cancer cells, respectively. Further studies on their

Synthesis, characterization and antimalarial activity of isoquinoline derivatives
This paper presents synthesis of novel decorated isoquinolines that can be used as antimalarial agents. Two series of compounds, isoquinoline phenyl and isoquinoline triazole derivatives, were synthesized via the Suzuki–Miyaura and Sharpless–Fokin reactions respectively. The final compounds were investigated for their antimalarialactivity in cell-based experiments. In the series of isoquinoline phenyl
