Description

General description

A water soluble (32 µM in water) BBB-permeable ATPZ (aminothienopyridazine) tau aggregation inhibitor that exhibited IC₅₀ of 8.1 µM in a heparin-induced tau assembly assay (monitored by thioflavine-T binding and fluorescence), and was further validated in vitro to reduce tau fibril formation (tau fragment K18PL, and full length tau40) by >50% in sedimentation assays. It also displayed very good B/P ratio (1.6) in a mice full PK study with good oral bioavailability and good metabolic stability. No cytotoxicity was observed at up to 100 µM in HEK-293 cells.
