Semax (ACTH 4-10 analog)
Also known as Met-Glu-His-Phe-Pro-Gly-Pro
Semax is a synthetic analog of ACTH fragment 4-10, extended with a C-terminal Pro-Gly-Pro sequence that markedly increases stability against peptidase degradation. The design goal was retention of the neurotropic effects attributed to the ACTH fragment while eliminating its corticotropic activity — the fragment does not stimulate steroidogenesis. Published work reports rapid upregulation of BDNF and NGF expression in hippocampal tissue. As with Selank, most primary literature is Russian-language and requires translation.
Research applications
- BDNF and NGF expression profiling in hippocampal tissue
- Dopaminergic and serotonergic system interaction studies
- Neuroprotection assays in ischemia models
- Peptidase stability studies of Pro-Gly-Pro extended analogs
Storage
Store lyophilized at -20°C protected from light. Reconstituted at 2-8°C for up to 30 days.
