Bioactive azaphilones from the fungus Penicillium multicolor CM01

Publication date: June 2016 Source:Phytochemistry Letters, Volume 16 Author(s): Chulida Hemtasin, Somdej Kanokmedhakul, Panawan Moosophon, Kasem Soytong, Kwanjai Kanokmedhakul Two new azaphilones, dechloroisochromophilone II (1) and epi-isochromophilone III (2), a new natural product, 5-hydroxy-4-methoxy-5,6-dihydro-2H-pyran-2-one (3), together with eleven known compounds, 4–14 were isolated from the fungus, Penicillium multicolor CM01. Their structures were elucidated by spectroscopic methods. Compounds 2, 8, 10 and 11 exhibited antimalarial activity against Plasmodium falciparum (IC50 2.1–7.8μg/mL), while compounds 9 and 10 showed antimycobacterial activity against Mycobacterium tuberculosis (MIC 6.2 and 50.0μg/mL, respectively). Compounds 2, 4, and 7–11 showed cytotoxicity against three cancer cell lines, KB, MCF-7 and NCI-H187 (IC50 2.2–35.2μg/mL). In addition, compounds 1, 5–8 and 11 showed a minimum inhibition requirement to acetylcholinesterase (AChE) assay in the range of 0.03–0.25nM. Graphical abstract

ConclusionMore effective thromboprophylaxis and pre-test assessment is necessary for EOC patients. For prediction VTE events, D-dimer levels (>4.215 μg/ml) were the independent predictors before operation. Age and debulking surgery were the independent predictors post operation.

This study provides strong evidence that following a healthy lifestyle can substantially extend the years a person lives disease-free." Commentary on Recent Evidence for Cognitive Decline to Precede Amyloid Aggregation in Alzheimer's Disease I can't say that I think the data presented in the research noted here merits quite the degree of the attention that it has been given in the popular science press. It is interesting, but not compelling if its role...

Macrophages are highly plastic cells with critical roles in immunity, cancer, and tissue homeostasis, but how these distinct cellular fates are triggered by environmental cues is poorly understood. To uncover how primary murine macrophages respond to bacterial pathogens, we globally assessed changes in post-translational modifications of proteins during infection with Mycobacterium tuberculosis, a notorious intracellular pathogen. We identified hundreds of dynamically regulated phosphorylation and ubiquitylation sites, indicating that dramatic remodeling of multiple host pathways, both expected and unexpected, occurred dur...

Whether you have a stomachache, a wrist sprain or a chronic disease, one of the first things doctors and nurses will do at an appointment is take your temperature. A normal temperature means your body is humming along the way it should. A higher temperature means you have a fever, and shows your body could be fighting an infection. And since 1871, “normal” has meant 98.6°F (37°C). That number was determined by a German physician, based on millions of readings from 25,000 German patients, taken by sticking thermometers under their arms. When doctors in the U.S. and Europe repeated the experiment in local...

​Before you break out the bottles for a paracentesis, you may want to consider doing a test for ascites. Many procedures require executing an old-school test before even looking at a result or grabbing an ultrasound machine. Knowing what to look for on a physical exam may guide your practice and intervention dramatically. Using noninvasive tools first could help your patient avoid other tedious or unnecessary testing, which may also result in lost time. Incorporating ultrasound into your practice may also help you nail a diagnosis or allow you to perform a procedure better than you expected.A markedly distended abdomen d...

Abstract Therapeutic potential of biosurfactant (BS) has been improved in recent years. Our present study deals with production of BS from Planococcus maritimus SAMP MCC 3013 in a mineral salt medium (MSM) supplemented with glucose (1.5% w/v). Further, BS has been purified and partially characterized as glycolipid type through our previous publication. Current research article aimed to evaluate biological potential of BS against Mycobacterium tuberculosis, Plasmodium falciparum and cancerous cell lines. Planococcus derived glycolipid BS was found to be a promising inhibitor of M. tuberculosis (MTB) H37Ra at I...

Authors: Underner M, Peiffer G, Perriot J, Jaafari N Abstract Cocaine can be responsible for many psychiatric and/or somatic disorders. The aim of this systematic literature review of data was to expose relations between cocaine use and pulmonary complications. Cocaine can be responsible for acute respiratory symptoms (cough, black sputum, hemoptysis, dyspnea, wheezing, chest pain) and for various pulmonary disorders including barotrauma (pneumothorax, pneumomediastinum, subcutaneous emphysema, pneumopericardium), airway damage, asthma, bronchiolitis obliterans with organizing pneumonia, acute pulmonary edema, alve...
