Aloxistatin (E-64d), is a selective cysteine protease inhibitor or calpain and autophagy inhibitor. E-64d prevents in vitro cerulein- induced trypsinogen activation. E-64d can enter the intact cell and inhibit calpain. E-64d has been shown safe for the treatment of Alzheimer's disease in human. E-64d is potentially useful in the treatment of developmental seizure-induced brain damage both by regulating abnormal zinc signal transduction and through the modulation of altered lipid metabolism via ApoE/clusterin pathway in hippocampus.

How to use

In Vitro:

Aloxistatin can enter the intact platelet and inhibit proteolysis by inhibiting calpain. Aloxistatin blunts Parathyroid hormone (PTH)-induced cell proliferation and inhibits differentiation osteoblasts in vitro.

In Vivo:

Aloxistatin (100 mg/kg, p.o.) strongly inhibits the cathepsin B&L activities in the skeletal muscle, heart and liver of hamsters. In spinal cord injury (SCI) rats, Aloxistatin provides neuroprotection in SCI lesion and penumbra. Aloxistatin reduces brain amyloid-β and improves memory deficits in Alzheimer's disease animal models by inhibiting cathepsin B activity.
