Calbistrins, novel antifungal agents produced by Penicillium restrictum. I. Production, taxonomy of the producing organism and biological activity.
TLDR
A novel antibiotic complex, named the calbistrins, has been discovered in the culture broth of a soil fungus, and the producing organism was identified as a strain of Penicillium restrictum. Expand
Tirandalydigin, a novel tetramic acid of the tirandamycin-streptolydigin type. I. Taxonomy of the producing organism, fermentation and biological activity.
TLDR
Tirandalydigin is a new tetramic acid antibiotic found in a screen designed to find compounds with activity against pathogenic anaerobic bacteria and possesses structural features that are common to both tirandamycin and streptolydigin. Expand
Macquarimicins, microbial metabolites from Micromonospora. I. Discovery, taxonomy, fermentation and biological properties.
TLDR
A novel series of microbial metabolites were discovered in fermentation broths of two soil isolates identified as strains of Micromonospora chalcea, and macquarimicin B has inhibitory activity against the leukemia cell line P-388. Expand
Novel Triterpene Sulfates from Fusarium compactum Using a Rhinovirus 3C Protease Inhibitor Screen.
© Japan Antibiotics Research Association Two novel triterpene sulfates have been isolated from Fusarium compactum by bioactivitydirected fractionation using an assay which measures the inhibition ofExpand
5-N-acetylardeemin, a novel heterocyclic compound which reverses multiple drug resistance in tumor cells. I. Taxonomy and fermentation of the producing organism and biological activity.
TLDR
The ardeemins are a new family of secondary metabolites produced by submerged fermentation of a fungus which was isolated from a soil sample collected in Brazil and potentiated the cytotoxicity of the anticancer agent vinblastine in multidrug resistant human tumor cells. Expand
Non-hyperfunctioning pancreatic endocrine tumors: multimodality imaging features with histopathological correlation
TLDR
NF-PNETs have variable imaging appearances but are most commonly oval shaped, solid, and well-defined/encapsulated masses, and hypovascular on late arterial and portal venous phase and low signal intensity on T2-WI correlates with extensive intratumoral fibrosis. Expand
Novel triterpene sulfates from Fusarium compactum using a rhinovirus 3C protease inhibitor screen.
Two novel triterpene sulfates have been isolated from Fusarium compactum by bioactivity-directed fractionation using an assay which measures the inhibition of proteolytic activity of rhinovirus 3CExpand
