摘要:
The present invention relates to novel substituted amino compounds of the formula I: R.sup.1 -(A).sub.a -(B).sub.b -(D).sub.c -(CH.sub.2).sub.m -N(R.sup.2)-(CH.sub.2).sub.n -R.sup.3 as defined in the present application, and to a process for preparing such compounds. The invention also includes pharmaceutical compositions containing the present compounds, and the preparation of such compositions. The invention also relates to the use of the present compounds as inhibitors of blood-platelet aggregation, formation of metastases by carcinoma cells, and the binding of osteoclasts to bone surfaces, in the treatment of hosts in need thereof.
摘要:
The invention relates to compounds of the formula I ##STR1## in which A denotes hydrogen or an amino protective group, B denotes one or more amino acids, X denotes alkylene or aralkylene, Y.sup.1, Y.sup.2, Y.sup.3 and Y.sup.4 are identical or different and denote hydrogen, methyl, methoxy or nitro, V denotes hydrogen or a carboxyl protective group, W denotes --[CH.sub.2 ].sub.n -- or --O--[CH.sub.2 ].sub.n --, m denotes 0 or 1, n denotes 0 to 6, and p denotes 0 to 5, to a process for their preparation. The compounds of formula I are useful as linkage agents or anchor groups in the solid-phase synthesis of peptide aminoalkylamides and peptide hydrazides.

The present invention relates to 2,4-dioxoimidazolidine compounds of the formula I ##STR1## a process for their preparation and their use as inhibitors of platelet aggregation, metastasis of carcinoma cells and osteoclast binding to the bone surfaces.
摘要:
The invention relates to new compounds of the formula ##STR1## in which R.sup.1 denotes (C.sub.1 -C.sub.8)-alkyl or optionally substituted (C.sub.6 -C.sub.14)-aryl, R.sup.2 denotes hydrogen or an amino acid residue which is protected by an amino protective group which can be cleaved off with weak acid or base, R.sup.3 denotes hydrogen or (C.sub.1 -C.sub.4)-alkyl, and Y.sup.1 -Y.sup.9 denote identical or different radicals hydrogen, (C.sub.1 -C.sub.4)-alkyl, (C.sub.1 -C.sub.4)-alkoxy or -O-(CH.sub.2).sub.n -COOH (with n=1 to 6), one of these radicals being -O-(CH.sub.2).sub.n -COOH. A process for the preparation thereof and the synthesis of peptide amides by means of a solid phase method using these new compounds (spacers) are described.
摘要:
What are disclosed are prostacylin PGI.sub.2 analogs of the formula ##STR1## having a more specific or longer lasting pharmacological action than PGI.sub.2, methods of making these analogs; and methods and pharmaceutical preparations for inhibiting blood platelet aggregation, for treating hypertension, for the treatment or prophylaxis of gastrointestinal ulcers, and for the treatment of asthma.
