The endogenous sulfated pentapeptide phytosulfokine-alpha stimulates tracheary element differentiation of isolated mesophyll cells of zinnia
C cultured zinnia cells produce nanomolar levels of PSKs under inductive conditions, suggesting that PSK-alpha is a factor responsible for TE differentiation of zinnio mesophyll cells.

The pyridine-pyrone moiety is important for eliciting potent ACAT inhibition and decreases the inhibitory activity with 20 to 200 times larger IC50 values than that of 1.
Malolactomycins C and D, new 40-membered macrolides active against Botrytis
A strain of Streptomyces was found to produce two new components of the 40-membered ring macrolides, malolactomycins C and D. They inhibited the growth of Botrytis cinerea in an agar medium and a…
Pyridindolols K1 and K2, new alkaloids from Streptomyces sp. K93-0711
Two new alkaloids with the beta-carboline skeleton, pyridindolols K1 and K2, were isolated from the culture broth of Streptomyces sp.
New Glycosidases Inhibitors , Panosialins D and wDProduced by Streptomyces sp
In the course of screening for new glycosidase inhibitors from actinomycetes, new panosialin analogs, which are named panosIALin D and wD (4 and 8, Fig. 1), have been isolated together with known panosiains, and were produced in the culture broth of Streptomyces sp.
OF ANTIBIOTICS THE STRUCTURES OF ATPENINS A 4 , A 5 AND B , NEW ANTIFUNGAL ANTIBIOTICS PRODUCED BY PENICILLIUM SP
The structures of atpenins A4, A5 and B, new antifungal antibiotics produced by Penicillium sp., have been deduced to be I, II and III, respectively, on the basis of spectroscopic and JH and 13C…
ANTIBIOTICS FROM A STREPTOMYCES SP . TAXONOMY , ISOLATION , AND PHYSICO-CHEMICAL AND BIOLOGICAL PROPERTIES
The present paper deals with taxonomy of the producing strain, fermentation, isolation, and physico-chemical and biological properties of jietacins A and B.
Fungal Metabolites with Herbicidal Activity
During our search for new bioactive microbial metabolites, a fungal soil isolate, Chrysosporium sp. FO-4712, was found to produce anti-Bacillus subtilis substances detectable in Davis defined medium.…
Elevated expression of caveolin-1 at protein and mRNA level in human cirrhotic liver : relation with nitric oxide
Examining the expression of caveolin and eNOS at the protein and mRNA levels in patients with hepatocellular carcinoma and hepatitis C-related cirrhosis and in control noncirrhotic liver specimens obtained from patients with metastatic liver carcinoma found enhanced caveolin-1 expression may be associated with a significant reduction in NO catalytic activity in Cirrhosis.
The Ecological Role of a Proteolytic Psychrophile , Flavobacterium limicola Belonging to the Cytophaga-Flavobacteria Cluster , in the Decomposition of Particulate Organic Nitrogen in Freshwater…
Microbes of the Cytophaga-Flavobacterium (CF) group, within the phylum Bacteroidetes, have been considered contributors to the early decomposition of particulate organic matter (POM) in sediments…
