Title: Innovator Spotlight: Denis Lessard and His Contributions to Shark Cartilage Research
Introduction: Denis Lessard is a prominent inventor based in Lévis, Canada, known for his innovative research and contributions in the field of biotechnology. With two patents to his name, Lessard has made significant strides in utilizing shark cartilage for therapeutic applications.
Latest Patents: Lessard's most recent patent focuses on the "Low molecular weight components of shark cartilage, processes for their preparation and therapeutic uses thereof." This invention introduces a novel process where organic solvent-containing solutions substitute pure water in the preparation of cartilage extracts. Various organic solvents have been explored to yield extracts rich in biologically active components, specifically targeting matrix metalloprotease (anti-MMP) activities. The patent describes the purification of total liquid extract from shark cartilage into two distinct fractions: one containing molecules weighing less than 1 kDa and the other between 1 to 500 kDa. To prevent aggregate formation and enhance stability, stabilizing agents like sucrose are incorporated. Both fractions exhibit promising anti-MMP and anti-tumor properties, establishing their potential in medical treatments aimed at inhibiting enzyme activities and metastasis formation.
