Candoxatril is the orally active prodrug[1] of candoxatrilat (UK-73967) human neutral endopeptidase (Neprilysin) as the neutral endopeptidase 24.11[2] complexed (RB-101) with phosphoramidon degrades and inactivates[3] a number of bioactive peptides. Two multiply connected folding domains[3] of the neutral endopeptidase locus[3] splicing of exons 1, 2a, or 2b to the common exon 3 composed of 24 exons of the human CALLA/NEP gene[2] containing the active site, it is known as peptidase family M13 (neprilysin family, clan MA(E)) the gluzincins a faint but significant structural relationship of the metzincins[4][5][6][7] to the thermolysin-like enzymes,[5] Zincin is the simplest descriptor of biological space.[8] The structure reveals two multiply connected folding domains which embrace a large central cavity containing the active site of the 5-indanyl ester prodrug candoxatril[9] and differs from phosphoramidon [N-(N-(((6-Deoxy-α-L-mannopyranosyl)oxy)hydroxyphosphinyl)-L- leucyl)-L-tryptophan] in several respects the structure of human neutral endopeptidase complexed with phosphoramidon is lost due to desolvation[9] of the enzyme and ligand on formation of the complex Candoxatril.
