The CAS register number of lonidamine is 50264-69-2. It also can be called as Diclondazolic acid and the IUPAC name about this chemical is 1-[(2,4-dichlorophenyl)methyl]indazole-3-carboxylic acid. The molecular formula about this chemical is C₁₅H₁₀Cl₂N₂O₂ and the molecular weight is 321.16. Classification code about this chemical are Anti-Infective Agents, Antineoplastic agents, Antiparasitic Agents, Antiprotozoal Agents, Antispermatogenic agents, Contraceptive Agents, Contraceptive Agents, Male, Drug / Therapeutic Agent, Mutation data, Noxae, Radiation-sensitizing agents, Reproductive Control Agents, Reproductive Effect and Trypanocidal agents. This chemical is narrow-spectrum anti-tumor and it can be used for a variety of tumors, such as breast cancer, prostate cancer, lung cancer and brain tumors and so on. Another is also a spermicidal drug. This chemical has been used in the treatment of brain tumours in combination with radiotherapy and temozolomide. Results showed that a combination of temozolomide and lonidamine at clinically achievable, low plasma concentrations, could inhibit tumour growth, and lonidamine could reduce the dose of temozolomide required for radiosensitization of brain tumours.
