+== Disease ==
+[https://www.uniprot.org/uniprot/CAH2_HUMAN CAH2_HUMAN] Defects in CA2 are the cause of osteopetrosis autosomal recessive type 3 (OPTB3) [MIM:[https://omim.org/entry/259730 259730]; also known as osteopetrosis with renal tubular acidosis, carbonic anhydrase II deficiency syndrome, Guibaud-Vainsel syndrome or marble brain disease. 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.<ref>PMID:1928091</ref> <ref>PMID:1542674</ref> <ref>PMID:8834238</ref> <ref>PMID:9143915</ref> <ref>PMID:15300855</ref>
+== Function ==
+[https://www.uniprot.org/uniprot/CAH2_HUMAN CAH2_HUMAN] Essential for bone resorption and osteoclast differentiation (By similarity). Reversible hydration of carbon dioxide.

+== Publication Abstract from PubMed ==
+An improved steroid sulfatase inhibitor was prepared by replacing the N-propyl group of the second-generation steroid-like inhibitor (2) with a N-3,3,3-trifluoropropyl group to give (10). This compound is 5-fold more potent in vitro, completely inhibits rat liver steroid sulfatase activity after a single oral dose of 0.5 mg/kg, and exhibits a significantly longer duration of inhibition over (2). These biological properties are attributed to the increased lipophilicity and metabolic stability of (10) rendered by its trifluoropropyl group and also the potential H-bonding between its fluorine atom(s) and Arg(98) in the active site of human steroid sulfatase. Like other sulfamates, (10) is expected to be sequestered, and transported by, erythrocytes in vivo because it inhibits human carbonic anhydrase II (hCAII) potently (IC(50), 3 nmol/L). A congener (4), which possesses a N-(pyridin-3-ylmethyl) substituent, is even more active (IC(50), 0.1 nmol/L). To rationalize this, the hCAII-(4) adduct, obtained by cocrystallization, reveals not only the sulfamate group and the backbone of (4) interacting with the catalytic site and the associated hydrophobic pocket, respectively, but also the potential H-bonding between the N-(pyridin-3-ylmethyl) group and Nepsilon(2) of Gln(136). Like (2), both (10) and its phenolic precursor (9) are non-estrogenic using a uterine weight gain assay. In summary, a highly potent, long-acting, and nonestrogenic steroid sulfatase inhibitor was designed with hCAII inhibitory properties that should positively influence in vivo behavior. Compound (10) and other related inhibitors of this structural class further expand the armory of steroid sulfatase inhibitors against hormone-dependent breast cancer.
