6-Fluoro-2-(2-methylphenyl)-1,2-benzisothiazol-3(2H)-one

Thr101, also known as NOX Inhibitor VII, is a dose-dependent inhibitor of HDAC1, HDAC3, HDAC4, HDAC5, HDAC6, HDAC7, HDAC8, and HDAC9. Thr101 is also a NOX inhibitor.

Thr101 is an inhibitor (IC50=2.9 μM) of phosphomannose isomerase (PMI).PMI can compete with phosphomannose mutase 2 (PMM2) for the binding site of Man-6-P and convert mannose-6-phosphate (Man-6-P) into fructose-6-phosphate (Fru-6-P) .Thr101 only specifically inhibits PMI and not PMM2. Thr101 can be used for research of congenital disorder of glycosylation type Ia (CDG-Ia)[1].

ChEBI: 6-fluoro-2-(2-methylphenyl)-1,2-benzothiazol-3-one is a member of benzothiazoles.
