  • Compositions for and medical use of water-soluble derivatives of 6,6-methylene-bis-(2,2,4-trimethyl-1,2-dihydroquinoline)
    Patent number: 4510147
    Abstract: The invention relates to water-soluble alkali salts of mono- and disulfonic acid derivatives and mono- and disulfonamide derivatives of 6,6'-methylene-bis-(2,2,4-trimethyl-1,2-dihydroquinoline) and dimer and/or trimer condensation products thereof bound with a methylene bridge at the 8 or 8' position. The new compounds are radioprotective and radiosensibilizers at the same time, and may be used both in the therapy and prophylaxis of malignant tumors.
    Type: Grant
    Filed: May 14, 1982
    Date of Patent: April 9, 1985
