Title: Amethopterin(methotrexate) pro-drugs, intermediate products, a preparation method, and compositions containing them
Inventor: STURTZ GEORGES
IPC: A61K31/675
Filed: 1991-04-23
Abstract: The synthesis of gem-diphosphonic amethopterin(methotrexate) analogues, and their use as pharmaceutical compositions for various therapeutical applications, are described. In particular, an association of the pro-drug concept with the pharmacological vectorization of antineoplastic agents for bone carcinomata, using diphosphonic acids, is desired. The gem-diphosphonic amethopterin(methotrexate) and 10-N-deaza amethopterin compounds have the form of an amethopterin pro-drug of which the gem-diphosphonic grouping is connected to the pteroylglutamic grouping by a peptide linkage. These compounds are particularly useful in cancerological pharmaceutical compositions particularly intended for treating tumours or metastases, especially those to bone, and/or in rheumatological pharmaceutical compositions particularly intended for treating resistant psoriatic rheumatism, polymyositis, Reiter's disease and rheumatoid arthritis.

Patent FR-2703170-A1 (FR)
Inventor: BRUNO DELEAN
IPC: G06T11/60
Filed: 1993-03-25
Abstract: Computerized processing method for an image, wherein the original image is sampled in order to retain only a grid of points of reduced or much lower definition than that of the original image and corresponding to the image displayed on a monitor. The processing to be carried out is broken down into elementary operations which may be summed at any time to display the partial result on the screen. The operations are carried out only on the functions and, it is only the global function of the intermediary stage, or of the whole treatment, which is then calculated with functional interpolation for the different intermediary points of the grid used, according to the definition of the final image to be obtained, and it is only after having calculated the function thus obtained for all the intermediary points that the data corresponding to said function are calculated. The process applies in general to image processing for the production of films, particularly color films for printing.
