Drug Name: IMS-088
Company: ImStar Therapeutics
Location: Canada
Drug Type: Small Molecule
Conditions: ALS
Mechanism Type: Proteostasis, Protein misfolding modulator
Mechanism: IMS-088 is a novel compound derived from withaferin A, a natural compound isolated from the leaves of the winter cherry plant, with improved pharmacological properties for a therapeutic drug. Studies in the SOD1 mouse model of ALS have shown that presymptomatic treatment with withaferin A prolongs survival in this model and reduces misfolded SOD1 levels. A subsequent analysis suggests this reduction may be due to, upon treatment, an increase in heat shock protein 25 (a mouse ortholog of heat shock protein 27).
U.S. Status for ALS: Preclinical
