Alsactide

Alsactide (INN; brand name Synchrodyn 1-17 or simply Synchrodyn; former development code Hoechst 433; also known as alisactide) is a synthetic peptide and analogue of adrenocorticotropic hormone (ACTH) which is used in Italy as a diagnostic agent in kidney function for adrenal insufficiency.^[1][2][3] Like ACTH, alsactide is thought to act as a non-selective agonist of the melanocortin receptors, including the ACTH receptor (MC₂R).^[4] However, it appears to show a different profile of receptor selectivity relative to ACTH, as it apparently demonstrated no evidence of inhibition of endogenous ACTH in Addison's disease patients.^[5]
