| 20080280934 | Method of Preparing Porphyrin Derivatives, Porphyrin Derivatives, Uses Thereof and Pharmaceutical Compositions - Method of preparing a porphyrin derivative starting from a meso-substituted porphyrin compound. According to the invention, the meso-substituted porphyrin compound used is a meso-(2′-cyanovinyl)-substituted porphyrin compound, wherein said meso-(2′-cyanovinyl)-substituted porphyrin compound, in a form in which its porphyrin ring is complexed with a bivalent metal ion is converted, in the present of an acid for which | 11-13-2008 |
| 20090215851 | Method of Preparing a Porphyrin Derivative, a Porphyrin Derivative, Use of Said Porphyrin derivative and a pharmaceutical composition containing said porphyrin derivative - The present invention relates to a method of preparing a porphyrin derivative from a meso-acrylonitrile-substituted porphyrin compound. According to the invention a Vilsmeier reagent carrying an aromatic ring is used, wherein said Vilsmeier reagent is a soft electrophile. The use of this Vilsmeier reagent results in a porphyrin derivative having the ring system of the Vilsmeier reagent condensed to its porphyrin macrocycle via two new 6 membered rings. Thus a new class of porphyrin derivatives is provided, wherein said derivatives are photodynamically more active than the starting compound. The invention also relates to a porphyrin derivative, use of said porphyrin derivative and a pharmaceutical composition containing said porphyrin derivative. | 08-27-2009 |

| 20100022889 | ULTRASOUND TREATMENT HEAD FOR AN APPARATUS FOR TREATING A PATIENT WITH ULTRASOUND - An ultrasound treatment head for an apparatus for treating a patient with ultrasound comprises at least one active element for converting an electric signal into ultrasound and a vacuum cup having an upper part and a lower part. The active element is mounted in the upper part and the vacuum cup provides a vacuum chamber with a holding space for a gel pad. The upper part is adapted to act as a spring suspension for the active element to lower the active element into the lower part. The active element is provided with a positioning ring protruding with respect to the active element. This positioning ring determines the location of the gel pad within the holding space. | 01-28-2010 |
