Osteopetrosis is a rare genetic disease characterized by abnormally dense bone, due to defective resorption of immature bone. The disorder occurs in two forms: a severe autosomal recessive form occurring in utero, infancy, or childhood, and a benign autosomal dominant form occurring in adolescence or adulthood. Autosomal recessive osteopetrosis is usually associated with normal or elevated amount of non-functional osteoclasts. OPTB3 is associated with renal tubular acidosis, cerebral calcification (marble brain disease) and in some cases with mental retardation. Function CAH2_HUMAN Essential for bone resorption and osteoclast differentiation (By similarity). Reversible hydration of carbon dioxide. Can hydrate cyanamide to urea. Involved in the regulation of fluid secretion into the anterior chamber of the eye. Publication Abstract from PubMed Here we report the synthesis of a series of taurine substituted sulfonamide derivatives 1-29 having the ureido moiety installed at the tail section as selective inhibitors of the tumor associated human (h) Carbonic Anhydrase (CA; EC 4.2.1.1) IX and XII. The series was deeply investigated for their kinetic features which demonstrated a strong dependence on the ureido moiety. High resolution X-ray crystallographic investigation on selected ligand adducts complexed with hCA II and hCA IX-mimic revealed a strong correlation between the ureido moiety and the amino acid residues Q92 and Q67 in both the hCA II and hCA IX-mimic, contributing to highly stabilized ligand-protein complex.
