Arglecin, a new microbial metabolite isolation and chemical structure.
A new streptomycete metabolite named arglecin was isolated from the culture filtrates of the strains KA57-AG3, KB59-M1 and the other 11 strains by the screening of compounds with positive Wood andExpand
A novel synthesis of 2-deoxy-α-glycosides
The key step of the synthesis involves the reaction of glycals [3,4,6-tri-O-acetyl-D-glucal (1), the new glycal derivative 4-O-acetyl-1,5-anhydro-2,6-dideoxy-3-C-methyl-3-O-methyl-L-ribo-hex-1-enitolExpand
KD16-U1, a new metabolite of Streptomyces: isolation and structural studies.
A new metabolite, KD16-U1, has been isolated from the culture of Streptomyces filipinensis and has been found to be closely related to shikimic acid. Expand
Fermentation of 3-amino-3-deoxy-D-glucose.
Biological properties of ME2303 (FAD-104), a new anthracycline.
From ECG changes, it seems that ME2303 did not show any effect on the heart in acute toxicity, and Mutagenicity was recognized as with ADM in the back-mutation test. Expand
Total synthesis of the disaccharide of bleomycin, 2-0-(α-D-mannopyranosyl)-L-gulopyranose
Abstract 2-0-(α- D -Mannopyranosyl)- L -gulopyranose, the sugar portion of bleomycin has been synthesized.
Studies on Antibiotics and Related Substances. VIII. Syntheses of the Two Enantiomorphs of 5-Methylenecyclopentanone-3-carboxylic Acid
1) The two diastereoisomeric mixtures (IIa and lIb) of 5-(dimethylaminomethyl)-cyclopentanone-3-carboxylic acid hydrochloride were synthesized from the two enantiomorphs ofExpand
The structure of chymostatin, a chymotrypsin inhibitor.
Chymostatin, a chymotrypsin inhibitor, was shown to be a mixture of components A, B and C, and the structure of component A as determined to be N-[((S)-1-carboxy-2-phenylethyl)-carbamoyl]-α-[L-glycyl-L-leucyl-phenylalaninal]. Expand
