PURPOSE:NG-Substituted-N<2>-alkoxynaphthalenesulfonylargininamides of the formula I [X and Y are protective groups of a guanidino group (one of them may be H); R is a group of the formula II (R1 and R2 are H, C1-10 alkyl, etc.) or the formula III(Z is a bivalent group in which 20 or less of groups of methylene, mono-substituted methylene, oxy, thio, etc. are bonding); and R' is a 1-naphthyl or 2-naphthyl group substituted with C1-10 alkoxy groups], or their acid salts. For example, 4-ethyl-1-(NG-nitro-N<2>-(5-methoxy-1-naphthalenesulfonyl)-L-arginyl) piperidine may be cited. |
