pharmacophore model for ATP-competitive inhibitors interacting with the active site of the EGFR proteintyrosinekinase and a putative binding mode of 4-anilinoquinazoline suggest that a salicylic acid function could serve as the pharmacophore replacement of a pyrimidine ring. Superpositions by CAMM of salicylanilides with the potent EGFR tyrosinekinaseinhibitor 4-[(3'-chlorophenyl)amino]-6,7-dimethoxyquinazoline

Nanothermometers composed from a gold nanorod core, temperature sensitive linker and fluorescent dye are reported. The nanothermometers have low fluorescence due to a self-quenching mechanism at temperatures below 50 °C and become highly fluorescence above 70 °C.

imaging of hERG potassium channels in living cells can provide useful information for hERG-correlation studies. Herein, three small-molecule fluorescent probes, based on the potent hERG channel inhibitor astemizole, for the imaging of hERG channels in hERG-transfected HEK293 cells (hERG-HEK293) and human colorectal cancer cells (HT-29), are described. These probes are expected to be applied in the physiological
health: Ferroquine is a ferrocene‐based analogue of the antimalarial drug chloroquine. In addition to the primary mechanism of quinoline action, fluorescent probe studies in infected red blood cells show another mechanism is at work. It is based on the production of HO. in the acidic and oxidizing environment of the digestive vacuole of the malaria parasite and implies that, with ferroquine, reinvasion
