Carboplatin-d₄is intended for use as an internal standard for the quantification of carboplatin by GC- or LC-MS. Carboplatin is a platinum-containing DNA-crosslinking agent.¹It induces the formation of DNA interstrand crosslinks and DNA-protein crosslinks when used at concentrations of 200 and 300 µM. It inhibits the proliferation of GLC-4 small cell lung carcinoma and A2780 and SKOV3 ovarian cancer cells (IC₅₀s = 22.7, 0.5, and 10.2 µM, respectively).^2,3Carboplatin reduces tumor growth in an ADJ/PC6 murine plasmacytoma model (ED₉₀= 0.6 mg/kg, i.p.).⁴Formulations containing carboplatin have been used in the treatment of ovarian cancer.
