    摘要: A recombinant vector suitable for industrially making an animal produce useful protein in the milk, which is constructed by extracting high molecular weight DNA from the bovine liver to prepare a chromosomal gene library, preparing a synthetic DNA probe corresponding to the publicly known bovine αS1 casein chromosomal gene, screening a clone carrying bovine αS1 casein chromosomal gene, confirming that the clone has a base sequence coincident with that of the publicly known bovine αS1 casein chromosomal gene, ligating human prourokinase cDNA with the promoter part and the intron 1 part of the gene, and then inserting the obtained plasmid into a suitable vector. A transgenic mouse prepared by using this recombinant vector secreted a considerable amount of human prourokinase as useful protein in its milk after delivery.

    摘要: A coating agent for delaying the release of a physiologically active substance to be administered per os to ruminants, comprising a veterinarially acceptable water-soluble, synthetic high molecular compound and ethylcellulose, said coating agent being stable in the first stomach of ruminants and capable of being effectively disintegrated in the fourth stomach of ruminants, characterized in that said coating agent further comprises at least one substance which is miscible with both of said high molecular weight compound and ethylcellulose and is insoluble in water. The coating agent protects the active substance from degradation in the first stomach of a ruminant at a pH of about 5.5 and rapidly breaks down in the fourth stomach at a pH of about 3, so releasing the active ingredient for absorption by the animal.

    摘要: This invention provides a new process for producing 7-amino-6-demethyl-6-deoxytetracycline (Compound 3) which is an intermediate for the synthesis of minocycline. Compound 3 can be obtained by reduction of Compound 1 using a dithionite as reducing agent. This invention also provides a method to produce Compound 3 from Compound 2 in one pot.
