Bortezomib Injection contains bortezomib which is a proteasome inhibitor. Bortezomib is a modified dipeptidyl boronic acid. The chemical name for bortezomib, the monomeric boronic acid, is [(1R)-3-methyl-1-[[(2S)-1-oxo-3-phenyl-2-[(pyrazinylcarbonyl) amino]propyl]amino]butyl] boronic acid. Bortezomib has the following chemical structure: The molecular weight is 384.24. The molecular formula is C 19 H 25 BN 4 O 4 . The solubility of bortezomib, as the monomeric boronic acid, in water is 3.3 to 3.8 mg/mL in a pH range of 2 to 6.5. Bortezomib Injection is available as a ready-to-use sterile solution for intravenous injection: Each mL of the 3.5 mg/3.5 mL (1 mg/mL) strength contains 1 mg of bortezomib, 10 mg mannitol, 0.82 mg sodium acetate, 20 mg dimethyl sulfoxide, in water for injection in a 5 mL single-dose vial. The pH may have been adjusted with hydrochloric acid or sodium hydroxide. Each mL of the 3.5 mg/1.4 mg/mL (2.5 mg/mL) strength contains 2.5 mg of bortezomib, 25 mg mannitol, 0.82 mg sodium acetate, 22 mg dimethyl sulfoxide, in water for injection in a 2 mL single-dose vial. The pH may have been adjusted with hydrochloric acid or sodium hydroxide. bortezomib-structure
