Clinical trials with MTDQ /6,6'-methylene-bis (2,2,4-trimethyl-1,2-dihydroquinoline)/ an antioxidant with radiation sensitizing effect

V ErdélyiS Eckhardt


Daily doses of 1320 mg MTDQ have been administered orally to 7 patients for 100 subsequent days. Biological half-life and serum concentration measurements were performed. Function of vital organs, as well as routine laboratory findings revealed that MTDQ did not induce any toxic changes. The effect of MTDQ on the radiosensitivity of hypoxic tumor cells was studied in a combined treatment modality including 12 patients. The action on tumor regression was found encouraging. It has been found remarkable, too, that due to the effect of MTDQ and radiotherapy some of the nonspecific and general symptoms (e. g. pruritus) also disappeared.

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.
