Products Often Used Together with VBIT-4

VBIT-12

It and VBIT-12 prevent mitochondrial dysfunction and apoptosis in T2D and lupus models by inhibiting VDAC1 oligomerization and correcting protein misdirection to the plasma membrane.

BAI1

It rescues the decreased inner mitochondrial membrane (IMM) protein levels after endolysosomal damage in human iPSC-derived macrophages (iPSDM) better than BAI1.

IFN alpha-IFNAR-IN-1 hydrochloride

It and IFN α-IFNAR-IN-1 with MnCl2 decrease the release of mitochondrial DNA and reduce lipid peroxidation and ROS levels in MC38 cells.

Z-VAD-FMK

It and ZVAD treatment demonstrate a robust response to anti-CD3 + anti-CD28 stimulation in COVID-A T cells.

Mechanism of Action

Targets/IC₅₀/Ki	VDAC mtDNA IFN
In vitro	VBIT-4 rapidly inhibits the loss of ATP, which is a consequence of its translocation to the plasma membrane caused by VDAC1 overexpression, in plVdac1-expressing INS-1 cells.
In vivo	VBIT-4 prevents increases in water consumption and polyuria in the db/db mice, also counteracts VDAC1 overexpression, preventing mistargeting to the β cell surface under glucotoxic conditions. Through the prevention of VDAC1 gene expression, this compound may have disease-modifying actions.
