  • Patent number: 5021236
    Abstract: Agents useful for influencing the relaxation times in NMR diagnostics, contain at least one paramagnetic, physiologically compatible complex salt comprising a chelate from an open-chain or cyclic complex-forming compound containing organic nitrogen, phosphorus, oxygen and/or sulfur, and a complexed ion of the lanthanide elements of atomic number 57-70 or of the transition metals of atomic numbers 21-29, 42 and 44, and, optionally, an inorganic or organic base or acid, wherein said chelate complex is bound to a biomolecule.
    Type: Grant

  • Patent number: 4369185
    Abstract: A method for production of novel antifungal 1,3,4-thiadiazole derivatives having a composition of the general formula ##STR1## wherein R.sub.1 and R.sub.2 are independently alkyl with from 1 to 6 carbon atoms, alkenyl with from 2 to 6 carbon atoms, alkinyl with from 2 to 6 carbon atoms or cycloalkyl with from 3 to 6 carbon atoms is provided. 1,3,4-thiadiazole derivatives of a composition of the general formula ##STR2## are reacted with a compound having the composition of the general formula R.sub.1 -SH resulting in compounds of a composition having the formula ##STR3## which in turn are oxidized with an organic or inorganic oxidant.
