their anticancerpotential. Compound 6h was found to be most active against all the tested cancer cell lines with IC50 values in the range of 4–11 μM and showed better or comparable activity to the reference drug against all the tested cell lines. Cell cycle analysis revealed that compound 6h induces apoptosis and G2/S arrest in MIA-Pa-Ca-2 cells. Compound 6h triggers mitochondrial potential loss in
The efficient linkage of a conjugate chalcone to n-propyltriethoxysilanes via a 1,2,3-triazole is reported. The synthesis involves a Claisen–Schmidt condensation followed by a copper(i) catalyzed azide–alkyne cycloaddition (CuAAC) reaction.

The synthesis and biological evaluation of two novel series of natural-product-like hybrids based on the chalcone, thiolactone and isatin scaffolds is herein described. Results for a 36-member beta-amino alcohol triazole library showed that the thiolactone-chalcones, with IC(50)s ranging from 0.68 to 6.08 mu M, were more active against W2 strain Plasmodium falciparum than the isatin-chalcones with IC(50)s of 14.9 mu M or less. Also of interest is falcipain-2 inhibitory activity displayed by the latter, whereas the thiolactone-chalcones lacked enzyme inhibitory activity. (C) 2010 Elsevier Ltd. All rights reserved.

The resulting broadening of the absorbance spectrum is a detriment to photoacoustic (PA) imaging since the signal intensity, accuracy, and image quality all rely on reliable spectral unmixing. To address this major limitation and further enhance the tumor-targeting ability of imaging agents, we have taken a biomimeticapproach to design a multivalent glucose moiety (mvGlu). We showcase the utility
