A CHIMERIC MICROTUBULE DISRUPTOR WITH EFFICACY ON A TAXANE RESISTANT CELL LINE

Publication Abstract from PubMed

A chimeric approach is used to discover microtubule disruptors with excellent in vitro activity and oral bioavailability; a ligand-protein interaction with carbonic anhydrase that enhances bioavailability is characterised by protein X-ray crystallography. Dosing of a representative chimera in a tumour xenograft model confirms the excellent therapeutic potential of the class.

Disease

[CAH2_HUMAN] Defects in CA2 are the cause of osteopetrosis autosomal recessive type 3 (OPTB3) [MIM: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.[1][2][3][4][5]

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.[6][7]
