摘要:
The present invention provides peptides as inhibitors of the binding of urokinase to the urokinase receptor. The peptides have the general structural formula (I): X1-[X2]n-X3-X4-K-Y-F-X5-X6-I-X7-W-[X8]m (I) in which X1, X2, X3, X4, X5, X6, X7 and X8 each denote an aminocarboxylic acid, n and m are each independently 0 or 1, K denotes an aminocarboxylic acid with a lysine side chain, Y denotes an aminocarboxylic acid with a tyrosine side chain, F denotes an aminocarboxylic acid with a phenyl-alanine side chain, I denotes an aminocarboxylic acid with an isoleucine side chain, W denotes an aminocarboxylic acid with a tryptophan side chain, and the monomeric building blocks are linked by —CONR1— or —NR1CO— bonds where R1 in each case independently denotes hydrogen, methyl or ethyl, and pharmaceutically compatible salts and derivatives thereof.
摘要:
A power semiconductor component and a method for producing such a component. The component comprises a semiconductor base body having a first doping. A pn junction is formed in the base body by a contact region having a second doping with a first doping profile. A field ring structure has a second doping with a second doping profile. The contact region and the field ring structure are arranged at respectively assigned first and second partial areas of a first surface of the base body. Both extend into the base body, wherein the base body has, for the field ring structure, a trench-type cutout assigned to each respective field ring, the surface of said cutout following the contour of the assigned doping profile.

A power semiconductor component and method for producing it. The component has a semiconductor base body with a first doping and a pn junction formed by a contact region having a second doping with a doping profile in the base body. The second contact region is arranged at a second surface of the base body and extends into the base body. The base body has a trench-type cutout with an edge area and a base area, wherein the base area is formed as a second partial area of the second surface, and wherein the second contact region extends from the base area via the edge area as far as a first partial area. Furthermore, the pn junction has a curvature adjacent to the edge area.
