The invention provides methods for detection of medical disorders, associated with cellular oxidative stress, cell degeneration and/or cell death. The invention further relates to compounds comprising a thiol (—SH) group, for detecting cells undergoing oxidative stress, degeneration and/or a death process. The invention further provides methods for utilizing the compounds in medical practice, for diagnostic and therapeutic purposes.
A copper(I) complex with a tripodal ligand containing a sulfur thioether residue formed a ɳ1-superoxido complex with dioxygen at −90 °C. The complex could be spectroscopically characterized, and the formation of this complex was analyzed. Furthermore, related copper(I) complexes were investigated which formed μ-1,2-trans-peroxido complexes.
Mitomycln derivatives having a novel substituted dithio- ethylamlno group an 7-position. These compounds are better than mitomycin C with respect to an oncostatic activity and toxicity. Specifically, compounds showing a wider effective administration region against sarcoma 180A, a higher life prolonging effect gainst P$88, and a less marrow depressing effect are disclosed. Some of them have a high water solubitity which is advantageous in forming a pharmaceutical preparation, thus facilitating preparation of excellent oncostatic agents.
