摘要:
A novel physiologically active polypeptide having antitumor activity obtained by improving human tumor necrosis factor (TNF). The amino acid sequence of the polypeptide essentially corresponds to that of human tumor necrosis factor, except that ten amino acids Nos. 1 to 10 are deleted and (Met).sub.n -Arg-Lys-Arg are added to the amino (NH.sub.2)-terminus, where n is 0 or 1. Other amino acid modifications can also be made to the polypeptide while retaining high antitumor activity. The novel polypeptide has less side effects that the natural-type TNF, particularly with respect to cytotoxicity. A a DNA fragment encoding the polypeptide, a recombinant plasmid containing the DNA fragment, a recombinant microorganism cell transformed with the plasmid, a method of producing a novel physiologically active polypeptide using the microorganism cell, and a pharmaceutical composition comprising the polypeptide as an active ingredient are also provided.
摘要:
This invention relates to a novel physiologically active polypeptide containing modified amino acids on both terminals at the amino-terminus and the carboxy-terminus in the amino acid sequence of the human tumor neclosis factor (human TNF), a recombinant plasmid containing a DNA region encoding the polypeptide, a recombinant microorganism cell transformed with the recombinant plasmid, a method of producing the polypeptide by cultivating the microorganism cell, a pharmaceutical composition containing the polypeptide and a method of purifying and recovering the polypeptide. The polypeptide in this invention has excellent antitumor activity compared to the human TNF and can be utilized as an active ingredient of a pharmaceutical composition having antitumor activity.

摘要:
A mouse-human chimaeric immunoglobulin heavy chain comprising (a) the amino acid sequence of a mouse immunoglobulin heavy chain variable region and (b) the amino acid sequence of a human immunoglobulin heavy chain constant region and reacting specifically with human common acute lympohocytic leukemia antigen and a chimaeric DNA fragment which encodes the amino acid sequence of the above mouse-human chimaeric immunoglobulin heavy chain.
摘要:
A plant growth promoter comprising as an active ingredient for plant growth promotion at least one phenylglycine selected from the group consisting of(1) monomeric phenylglycines,(2) N-phenylglycylphenylglycines, and(3) cyclic dimers of phenylglycines.
摘要:
A novel phenoxycarboxylic acid of formula (I) is disclosed. The compound is effective as herbicide for eradicating broad-leaved weeds. A combination of the phenoxycarboxylic acid and a N-phosphonomethylglycine or a glufosinate which is known as a herbicide is very effective for eradicating both broad-leaved weeds and narrow-leaved weeds.
摘要:
The oxidative coupling of benzene or benzene derivatives to form the corresponding diphenyls, comprising contacting benzene or a benzene derivative, such as toluene, with molecular oxygen using as a catalyst .beta.-diketo complexes of palladium such as acetylacetone-palladium complex. Use of at least one zirconium compound such as zirconium oxystearate in conjunction with the catalyst gives an increased catalytic activity. The diphenyls are intermediates for production of dyestuffs, pharmaceuticals and other chemicals, and also find application in the preparation of high-molecular-weight polyesters and polyamides.
摘要:
A process for preparing amino alcohols, which comprises reacting a polyhydric alcohol containing at least one primary alcoholic hydroxyl group and at least one secondary alcoholic hydroxyl group and expressed by the following general formula ##STR1## wherein R.sup.1 is an alkyl group, R.sup.2 and R.sup.3 are identical or different and represent a hydrogen atom or a lower alkyl group an n is an integer of 0 to 3,With ammonia in the presence of specified hydrogenation catalyst thereby to aminate the secondary alcoholic hydroxyl group of the polyhydric alcohol selectively.
