Structure of synthetic calcimimetic and calcilytic compounds. (A) Synthetic type II calcimimetics comprise a structurally diverse group of compounds, which include phenylalkylamines such as NPS R‐568 and cinacalcet; AC265347, which has a benzothiazole structure; and etelcalcetide, which is a polycationic peptide. (B) All calcilytics described to date are synthetic compounds and are divided into two classes: amino alcohols such as NPS 2143, ronacaleret, NPSP795 and JTT‐305/MK‐5442 and the quinazolinone‐derived calcilytics such as AXT 914 and ATF 936.
