摘要:
The disclosure relates to a process of preparing relaxin from aqueous, decaseined milk or milk concentrate. Proteins are precipitated and separated, and a relaxin-containing precipitate is produced subsequently. The relaxin-containing precipitate is then purified in the customary manner. There is also disclosed a pharmaceutically active product containing such relaxin.
摘要:
Substituted carbonic acid esters and urethanes having the formula ##STR1## wherein Ad is a substituted or unsubstituted 1-adamantyl residue, R.sup.1 and R.sup.2 are saturated alkyl groups and X is chlorine, fluorine, azido or unsubstituted or substituted phenoxy. These compounds can be used in the synthesis of various peptides.

The present invention relates to isolated mistletoe lectin polypeptides and the pharmaceutical composition comprising the polypeptides thereof. Also, the present invention relates to processes for the production of mistletoe lectin polypeptides in homologous and heterologous host systems and mistletoe lectin peptides. Further, nucleic acid molecules are provided, which encode these mistletoe lectin polypeptides, and also pharmaceutical compositions comprising mistletoe lectin nucleic acids.
摘要:
The present invention relates to processes for the production of mistletoe lectin polypeptides in homologous and heterologous host systems and mistletoe lectin peptides as such. Further, nucleic acid molecules are provided, which code for these mistletoe lectin polypeptides, and also pharmaceutical compositions which contain these mistletoe lectin polypeptides or mistletoe lectin nucleic acids. In order to produce the many mistletoe lectin isoenzymes contained in the natural mistletoe extract, which can trigger anti-tumorigenic and mood-brightening effects, in sufficient quantities, the present invention provides a process which makes it possible to produce mistletoe lectins in required quantities biotechnologically and at the same time to recreate the diversity of the natural mistletoe extract in mistletoe lectin isoenzymes.
