• the resin is suspended in a 1: 1 mixture of ACN / H 2 0 (6 ml) in a plastic syringe, slowly stirred with a magnetic stirrer and irradiated for 8 hours with a TQ 150 mercury immersion lamp. Removal of the solvent and cleaning with semipreparative HPLC gives (3S) -3- [4- (3- guanidinobenzoyl) semicarbazido] succinamic acid, trifluoroacetate
• Example A Injection glasses
• a solution of 100 g of an active ingredient of the formula I and 5 g of disodium hydrogenphosphate is adjusted to pH 6.5 in 3 l of double-distilled water with 2N hydrochloric acid, sterile filtered, filled into injection glasses, lyophilized under sterile conditions and sealed sterile. Each injection glass contains 5 mg of active ingredient.
• a mixture of 20 g of an active ingredient of the formula I is melted with 100 g of soybean ecithine and 1400 g of cocoa butter, poured into molds and allowed to cool. Each suppository contains 20 mg of active ingredient.
• a solution of 1 g of an active ingredient is prepared of the formula I, 9.38 g of NaH 2 P0 4 • 2 H 2 0, 28.48 g Na 2 HP0 4 • 12 H 2 0 and 0.1 g of benzalkonium chloride in 940 ml of double distilled water. It is adjusted to pH 6.8, made up to 1 I and sterilized by irradiation. This solution can be used in the form of eye drops.
• Example D ointment
• 500 mg of an active ingredient of the formula I are mixed with 99.5 g of petroleum jelly under aseptic conditions.
• Example F coated tablets
• Example E tablets are pressed, which are then coated in a conventional manner with a coating of sucrose, potato starch, talc, tragacanth and colorant.
• Example G capsules
• each capsule contains 20 mg of the active ingredient.
• a solution of 1 kg of active ingredient of the formula I in 60 l of double-distilled water is sterile filtered, filled into ampoules, lyophilized under sterile conditions and sealed sterile. Each ampoule contains 10 mg of active ingredient.
