AOD-9604 5mg· 5mg

The precise mechanism of AOD-9604 remains incompletely characterized despite three decades of research interest. The peptide corresponds to a region of growth hormone not directly involved in canonical GHR engagement, and binding affinity to the somatogenic receptor is negligible in radioligand assays. Instead, the molecule has been proposed to act through a distinct, as-yet-undefined receptor or through allosteric modulation of beta-adrenergic signaling in adipocytes.

In rodent adipocyte preparations, AOD-9604 has been observed to elevate cAMP and stimulate hormone-sensitive lipase activity, increasing free fatty acid release. Reductions in fatty acid synthase expression and acetyl-CoA carboxylase activity have been reported in some studies, consistent with reduced de novo lipogenesis. Effects on chondrocyte metabolism, including upregulation of aggrecan and type II collagen synthesis, have been observed in cartilage explant models, generating interest in osteoarthritis research applications.
