Hi1a is a naturally occurring bivalent spider-venom peptide that is being investigated as a promising molecule for limiting ischemic damage in strokes, myocardial infarction, and organ transplantation. However, the challenges associated with the synthesis and production of the peptide in large quantities have slowed the progress in this area; hence, access to synthetic Hi1a is an essential milestone for the development of Hi1a as a pharmacological tool and potential therapeutic.
