General description

6-Chloro-3-formyl-7-methylchromone (6-Chloro-7-methyl-4-oxo-4H-1-benzopyran-3-carboxaldehyde) is a benzopyran derivative. It is a bicyclic heterocyclic molecule made up of a benzene ring fused to a heterocyclic pyran ring.

Application

6-Chloro-3-formyl-7-methylchromone is the suitable reagent used in a study to investigate the multidrug resistabnce reversal by some 3- formylchromones in human colon cancer and mouse lymphoma cells transfected with the human MDR1 gene. It is the suitable reagent used in the synthesis of uridine-based library.

Several new 3-formylchromone derivatives proved to be modifiers of multidrug resistance in mouse lymphoma cells and in human Colo320 colon cancer cells. There is apparently a structure-activity relationship between the antiproliferative multidrug resistance-reversing effect and the chemical structure of the

The polypeptide N-acetyl-alpha-galactosaminyltransferases (ppGalNAcTs, also abbreviated ppGaNTases) initiate mucin-type O-linked glycosylation and therefore play pivotal roles in cell-cell communication and protection of tissues. In order to develop new tools for studying mucin-type O-linked glycosylation, we screened a 1338 member uridine-based
