γ-Glutamyl transpeptidase (GGT) is a cell-membrane-bound enzyme that is involved in various physiol. and pathol. processes and is regarded as a potential biomarker for many malignant tumors, precise detection of which is useful for early cancer diagnosis. Herein, a new GGT-activatable near-IR (NIR) fluorescence imaging probe (GANP) by linking of a GGT-recognitive substrate γ-glutamate (γ-Glu) and a NIR merocyanine fluorophore (mCy-Cl) with a self-immolative linker p-aminobenzyl alc. (PABA) is reported. GANP was stable under physiol. conditions, but could be efficiently activated by GGT to generate â?00-fold enhanced fluorescence, enabling high sensitivity (detection limit of â?.6 mU L-1) and specificity for the real-time imaging of GGT activity as well as rapid evaluation of the inhibition efficacy of GGT inhibitors in living tumor cells. Notably, the deep tissue penetration ability of NIR fluorescence could further allow GANP to image GGT in frozen tumor tissue slices with large penetration depth (>100 μm) and in xenograft tumors in living mice. This GGT activatable NIR fluorescence imaging probe could facilitate the study and diagnosis of other GGT-correlated diseases in vivo. This study involved multiple reactions and reactants, such as 4-Chlororesorcinol (cas: 95-88-5Safety of 4-Chlororesorcinol).
4-Chlororesorcinol (cas: 95-88-5) belongs to organic chlorides. Chlorinated organic compounds are found in nearly every class of biomolecules and natural products including alkaloids, terpenes, amino acids, flavonoids, steroids, and fatty acids.While alkyl bromides and iodides are more reactive, alkyl chlorides tend to be less expensive and more readily available. Alkyl chlorides readily undergo attack by nucleophiles.Safety of 4-Chlororesorcinol
