Progestin Structures

Meaning

Progestin structures refer to the distinct chemical configurations of synthetic compounds that mimic the biological activity of the endogenous hormone progesterone by binding to the progesterone receptor. These structures are broadly classified based on their parent steroid molecule, such as pregnanes, estranes, or gonanes, and each possesses a unique profile of receptor binding affinity and potential for cross-reactivity with other steroid receptors. The specific structure dictates the clinical efficacy and side-effect profile of a given progestin.
