Description:

Pseurotin A has immunosuppressive activity, it inhibits immunoglobulin E(IgE) production in vitro.It shows a moderate effect against the phytopathogenic bacteria Erwinia carotovora and Pseudomonas syringae, with IC50 values of 220 and 112 microg ml(-1), respectively. Pseurotin A shows to be active against the proliferation of four different glioma cells with IC50 values of 0.51-29.3 uM, the targeting multiple metabolic enzymes might be one of the antiglioma mechanisms of pseurotin A.

Targets:

Antifection | Immunology & Inflammation related

Cycloaspeptide A and pseurotin A from the endophytic fungus Penicillium janczewskii.[Pubmed: 18669024]

Penicillium janczewskii K. M. Zalessky was isolated as an endophytic fungus from the phloem of the Chilean gymnosperm Prumnopitys andina.
METHODS AND RESULTS:
When grown in liquid yeast extract-malt extract-glucose broth, the fungus produced two main secondary metabolites. The compounds were for the first time isolated from this species and identified by spectroscopic methods as Pseurotin A and cycloaspeptide A. This is the first report on the production of cyclic peptides by endophytic fungi from Chilean gymnosperms.
CONCLUSIONS:
Pseurotin A and cycloaspeptide A presented low cytotoxicity towards human lung fibroblasts with IC50 > or = 1000 microM. Pseurotin A showed a moderate effect against the phytopathogenic bacteria Erwinia carotovora and Pseudomonas syringae, with IC50 values of 220 and 112 microg ml(-1), respectively.

Pseurotin A and its analogues as inhibitors of immunoglobulin E [correction of immunoglobuline E] production.[Pubmed: 19179074 ]

METHODS AND RESULTS:
A natural product, Pseurotin A inhibits IgE production in vitro. Wide variety of chemical modification of Pseurotin A was performed.
CONCLUSIONS:
Structure-activity relationship studies of Pseurotin Analogues elucidated that 10-deoxyPseurotin A strongly inhibits IgE production with IC(50) of 0.066 microM. An immunosuppressive activity of another natural product, synerazol was also found.

Pseurotin A Description

Source:	The cultures of marine Bacillus sp. FS8D.
Solvent:	Chloroform, Dichloromethane, Ethyl Acetate, DMSO, Acetone, etc.
Storage:	Providing storage is as stated on the product vial and the vial is kept tightly sealed, the product can be stored for up to 24 months(2-8C). Wherever possible, you should prepare and use solutions on the same day. However, if you need to make up stock solutions in advance, we recommend that you store the solution as aliquots in tightly sealed vials at -20C. Generally, these will be useable for up to two weeks. Before use, and prior to opening the vial we recommend that you allow your product to equilibrate to room temperature for at least 1 hour. Need more advice on solubility, usage and handling? Please email to: service@chemfaces.com
After receiving:	The packaging of the product may have turned upside down during transportation, resulting in the natural compounds adhering to the neck or cap of the vial. take the vial out of its packaging and gently shake to let the compounds fall to the bottom of the vial. for liquid products, centrifuge at 200-500 RPM to gather the liquid at the bottom of the vial. try to avoid loss or contamination during handling.

Antiglioma pseurotin A from marine Bacillus sp. FS8D regulating tumour metabolic enzymes.[Pubmed: 28641457]

METHODS AND RESULTS:
Pseurotin A was isolated from a culture of marine Bacillus sp. FS8D and showed to be active against the proliferation of four different glioma cells with IC50 values of 0.51-29.3 μM. It has been found that Pseurotin A downregulated the expression of tumour glycolytic enzymes pyruvate kinase M2 (PKM2) and lactate dehydrogenase 5 (LDH5) and upregulated the expression of pyruvate dehydrogenase beta (PDHB), adenosine triphosphate synthase beta (ATPB) and cytochrome C (Cyto-C), the important regulators for tricarboxylic acid cycle and oxidative phosphorylation.
CONCLUSIONS:
The data suggested that targeting multiple metabolic enzymes might be one of the antiglioma mechanisms of Pseurotin A.
