Abstract: The preparation of vitamin D compounds of formula (I) with a label attached to a spacer group in the 3 position is disclosed. In the above formula (I), O represents the oxygen atom of an ether group; Y represents hydrogen or hydroxy; A represents a label such as biotin, digoxigenin, or another vitamin D group; R represents a substituted hydrocarbon side-group of vitamin D or a vitamin D metabolite. Also disclosed is a method of measuring 25-hydroxy vitamin D metabolite and a 1?,25-dihydroxy vitamin D metabolite in a sample.

Abstract: 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. The present invention also relates to isolated mistletoe lectin polypeptides and pharmaceutical compositions comprising said polypeptides.

Abstract: 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.

In the above formula (I), O represents the oxygen atom of an ether group; Y represents hydrogen or hydroxy; A represents a label such as biotin, digoxigenin, or another vitamin D group; R represents a substitured hydrocarbon side-group of vitamin D or a vitamin D metabolite. Also disclosed is a method of measuring 25-hydroxy vitamin D metabolite and a 1?,25-dihydroxy vitamin D metabolite in a sample.

Abstract: Vitamin D compounds of formula (I) with a label attached to a spacer group in the 3 position are disclosed. In the above formula (I), X is an optionally substituted hydrocarbon group with a length of 0.8-4.2 nm, optionally containing the heteroatoms S, O, N or P; Y is H or OH; A is a label capable of binding with high affinity to a protein; R is an optionally substituted hydrocarbon side chain of a D vitamin or a D vitamin metabolite. Also disclosed is the preparation of formula (I).

Abstract: A process is disclosed for the preparation of new N.sup..tau. -substituted histidine derivatives of the general formula ##STR1## According to the process, a histidine derivative of the general formula ##STR2## is reacted with phosgene, and the resultant product is then alkylated and thereafter hydrolyzed with an acid.The products obtained by the process are highly useful for prepration of histidine-analogous proteins and enzymes.

Abstract: 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.

Abstract: 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.
