Mechanistic description

Inhibitors containing molecular recognition elements that only bind HSP70 when it adopts conformations specific to pathological tau engagement, exploiting differences in HSP70 structure when bound to misfolded versus properly folded tau species.

Mechanism / pathway

  1. HSPA1A
  2. drug discovery
