Abstract From the Canadian patent

The invention relates to methods of unfolding proteins using metal complexes particularly cobalt-containing Schiff's base compounds. The proteins can be viral proteins or myoglobin, and the unfolding can be irreversible under physiological conditions. The unfolded proteins exhibit UV/vis absorption spectral changes (see the figure) and a 5 % or greater change in at least one minima or maxima of the circular dichroism spectra of the proteins.

Why it's free to use

  • Filed July 16, 1998. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended July 16, 2018.
  • A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by July 16, 2020.
  • We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
