Description

Allo-aca, a leptin peptidomimetic, is a potent, specific leptin receptor antagonist peptide. Allo-aca blocks leptin signaling and action in numerous in vitro and in vivo models[1][2].

In Vitro

Allo-aca inhibits leptin-induced proliferation of MDA-MB-231 cells at 50 pM concentration. Allo-aca inhibits leptin-induced proliferation of MCF-7 cells with an IC50 of 200 pM[1].
Allo-aca at 250 nmol/L reduces VEGF-dependent leptin mRNA expression in both cell lines below base levels. Allo-aca inhibits VEGF mitogenic effects. Allo-aca inhibits VEGF-induced chemotaxis and chemokinesis in RF/6A retinal endothelial cells[2].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

In Vivo

In an MDA-MB-231 orthotopic mouse xenograft model, Allo-aca administered subcutaneously significantly extends the average survival time from 15.4 days (untreated controls) to 24 and 28.1 days at 0.1 and 1mg/kg/day doses, respectively[1].

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
