Description

General description

A cell permeable benzoquinolizine based compound that acts as a monoamine-depleting agent by blocking the activity vesicular monoamine transporter 2. Promotes late-stage differentiation of Pdx1-positive pancreatic progenitor cells into Neurog3 (Ngn3)-positive endocrine precursors without increasing their proliferation. Increases the number of insulin expressing cells in a dose dependent manner (EC₅₀ = 220 nM) and this effect is significantly enhanced when cells are simultaneously treated with dibutyryl cAMP. Embryonic stem cells treated with TBZ and/or dibutyryl cAMP and then grafted into kidney capsule of AKITA mice reduce hyperglycemia, improve fasting blood glucose levels, and show an increase in plasma C-peptide levels.
