A hepatocyte-targeting fluorescent probe for imaging isoniazid-induced hydrazine in HepG2 cells and zebrafish†
Abstract
A hepatocyte-targeting fluorescent N2H4 probe, GHP, was first designed and synthesized employing N-acetylgalactosamine (GalNAc) as the hepatocyte-targeting group and 3-nitrophthalimide as the recognition moiety. The probe can be used to selectively image N2H4 produced by the hydrolysis of isoniazid in HepG2 cells and the liver of zebrafish in situ.
