摘要:
Thrombin inhibitors from the hirudin family which differ from the previously known hirudins by mutation in the protein chain, and a process for their preparation are described. The novel hirudins are distinguished by a high specific activity, high stability and good pharmacokinetics.
摘要:
The present invention relates to hirudin derivatives which are formed from hirudin or the physiologically acceptable salt thereof and a carrier, to a process for the preparation thereof, and to the use thereof as thrombin inhibitor.
摘要:
The invention relates to novel synthetic isohirudins which have improved stability owing to exchange in the region of the Asp-Gly motif. This results, on the one hand, in an increase in the yield during workup and, on the other hand, in making possible pharmaceutical formulation as directly injectable solution ready for use.

摘要:
A hirudin derivative which has the N-terminal amino acid sequence Leu-Thr-Tyr-Thr-Asp shows high biological activity. Moreover, this hirudin derivative can be obtained very efficiently by genetic engineering preparation in yeasts.
摘要:
The invention relates to a process for the isolation and purification of hirudin from complex and salt-containing solutions by hydrophobic chromatography, using as stationary phase porous adsorber resins and as mobile phase organic solvents which are miscible with water.
摘要:
The invention relates to a new active substance--amblyommin--for anticoagulant therapy and to a process for the isolation thereof from hard ticks. The isolated protein having a thrombin-inhibitory action has a molecular weight of 20000 to 30000 dalton, an isoelectric point between 5.05 and 5.65 and the partial amino acid sequencesIle-Leu-Phe-Thr-Gln-Gly-Asn-X-Gly-Glu-Leu-Glu-Asn-X-Phe-Glu-,Lys-Ile-Leu-Phe-X-Gln-Gly- andAla-Ser-Tyr-Ile-Val-X-Ser-Glu-Ser-Ile-Gln-Ile-Leu-X-Leu-Ser-Glu-Gly-Ile-in which each radical X can be identical or different and each represents a naturally occurring amino acid.
摘要:
The invention relates to a polypeptide of the formula ##STR1## in which R represents phenoloic hydrogen or a phenolic ester group and m, n, X, Z, A, B, C, D, E, F, G, I and J have the meanings given, and in which the 6 Cys radicals are linked in pairs via disulfide bridges, processes for the preparation or isolation thereof, their use and agents containing them.
摘要:
The invention relates to a polypeptide which can be isolated from thymus glands and has an action on the immunological system, and which has a molecular weight of 3,480, a UV absorption with a maximum at 205 to 210 nm and an isoelectric point of 3.95+0.15 and a specific aminoacid composition, the N-terminal, if appropriate, carrying an acyl group or an acylglycyl group, processes for its isolation and purification, its use, agents containing this polypeptide, and its cleavage products, their use and agents containing them.
