Pharmacodynamics

The company is hoping that NRP409 will mark a significant improvement in thyroid HRT by reducing the variability of the more active hormone's availability, while reducing the safety risk associated with other T3 based therapies.

Mechanism of action

NRP409 is presumed to work like the endogenous thyroid hormone thyroxine (T4, a tetra-iodinated tyrosine derivative). In the liver and kidney, T4 is converted to T3, the active metabolite. In order to increase solubility, the thyroid hormones attach to thyroid hormone binding proteins, thyroxin-binding globulin, and thyroxin-binding prealbumin (transthyretin). Transport and binding to thyroid hormone receptors in the cytoplasm and nucleus then takes place. Thus by acting as a replacement for natural thyroxine, symptoms of thyroxine deficiency are relieved.
