Lung cancer cells harboring activating EGFR mutations acquire resistance to EGFR tyrosine kinase inhibitors (TKIs) by activating several bypass mechanisms, including MET amplification and overexpression. We show that a significant proportion of activated MET protein in EGFR TKI-resistant HCC827 lung cancer cells resides within the mitochondria. Targeting the total complement of MET in the plasma membrane

Les groupes anioniques et nucleophiles sur la chaine laterale des ylures de triphenylphosphonium provoquent un deplacement de la stereochimie de l'alcene obtenu vers l'isomere trans dans les reactions avec des aldehydes. L'effet est souvent plus important avec des aldehydes aromatiques qu'avec des aldehydes aliphatiques. Les substituants etudies sont les groupes oxydo, carboxylate, amino et amido

Efficient radiolabeling reactions are important chemical tools in biomedical research especially in probe construction. Herein, three 18F-labeled vinyl sulfones were prepared. In particular, 18F-PEG1-VS (((2-(2-(fluoro-18F)ethoxy)ethyl)sulfonyl)ethane) could not only allow chemoselective labeling of bioactive molecules containing −XH (X = S, NH) groups, but also react with red blood cells both in vitro and in living mice for potential cell tracking applications. In addition, these hydrophilic agents were found to cross the blood brain barrier (BBB) efficiently and localize at the cerebellum region. In summary, 18F-labeled vinyl sulfones provide a versatile platform for PET probe construction.
