Overview

Information

Aloxistatin (E64d) Aloxistatin (E64d) is an irreversible and membrane-permeable cysteine protease inhibitor with blood platelet aggregation inhibiting activity. The cysteine protease cathepsin L is required for SARS-CoV-2 viral entry, and aloxistatin tr
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.
