Examples of various β-glucan glycosidic linkages.
beta 1, 3- glucan and beta 1, 6- glucan.
Food Ingredient Sourced From Yeast
The shiitake mushroom contains beta-glucans.
β-Glucans (beta-glucans) are polysaccharides of D-glucose monomers linked by β-glycosidic bonds. β-glucans are a diverse group of molecules that can vary with respect to molecular mass, solubility, viscosity, and three-dimensional configuration. They occur most commonly as cellulose in plants, the bran of cereal grains, the cell wall of baker’s yeast, certain fungi, mushrooms and bacteria. Some forms of beta glucans are useful in human nutrition as texturing agents and as soluble fibersupplements, but can be problematic in the process of brewing.
Oat is a rich source of the water-soluble fibre (1,3/1,4) β-glucan, and its effects on health have been extensively studied the last 30 years. Oat β-glucans are the only dietary fiber currently recognized by the European Food Safety Authority (EFSA) to be able to reduce a disease risk. Oat β-glucans can be highly concentrated in different types of oat brans.
“Barley has more beta glucan fiber than any other grain” claims a report on DiabetesHealth website ; 11 sources are listed.
Yeast and medicinal mushroom derived β-glucans are notable for their ability to modulate the immune system. One study has shown that insoluble (1,3/1,6) β-glucan, has greater biological activity than that of its soluble (1,3/1,4) β-glucan counterparts.The differences between β-glucan linkages and chemical structure are significant in regards to solubility, mode of action, and overall biological activity.
β-GLUCAN
‘Gecono’ β-Glucan (GNP80), derived from fresh food grade brewer’s yeast or baker’s yeast, is akind of ‘new resource food material’ developed by unique innovative biotechnologies. Its maincomponent is yeast sourced immunocompetent polysaccharide which has two isomers structured asbeta 1, 3- glucan and beta 1, 6- glucan.

Eli Lilly’s Profit Slides, Gets Priority Review for Ramucirumab
Eli Lilly’s third-quarter earnings fell 9 percent compared with last year, when the maker of Cymbalta and Cialis booked a sizeable revenue-sharing payment from a former drug developer partner.
The Indianapolis company beat Wall Street expectations for the quarter and narrowed its earnings forecast for the year.
Lilly also said Wednesday that the U.S. Food and Drug Administration will give its stomach cancer treatment ramucirumab a priority review, which means the drugmaker will learn about its fate inside of eight months rather than a year, which is the norm.

Eli Lilly and Co. announced that results from the Phase 3 REGARD trial of ramucirumab (IMC-1121B) as a single agent in patients with advanced gastric cancer who have had disease progression after initial chemotherapy were published today in The Lancet. REGARD is the first Phase 3 study with either a single-agent biologic or an anti-angiogenic therapy to show improved overall survival and progression-free survival in advanced gastric cancer patients.
READ ALL AT
Ramucirumab (IMC-1121B)[1] is a fully human monoclonal antibody (IgG1) being developed for the treatment of solid tumors. It is directed against the vascular endothelial growth factor receptor 2 (VEGFR2). By binding to VEGFR2 it works as a receptor antagonist blocking the binding of vascular endothelial growth factor (VEGF) to VEGFR2. VEGFR2 is known to mediate the majority of the downstream effects of VEGF inangiogenesis.
Ramucirumab is being tested in several phase III clinical trials for the treatment of metastatic gastric adenocarcinoma,[2] non-small cell lung cancer,[3] among other types of cancer. On September 26, 2013 Eli Lilly announced that its Phase III study for ramucirumab failed to hit its primary endpoint on progression-free survival among women with metastatic breast cancer.[4][5]
This drug was developed by ImClone Systems Inc. It was isolated from a native phage display library from Dyax.

Jun. 7, 2013– Gilead Sciences, Inc. today announced that the U.S. Food and Drug Administration (FDA) has granted priority review to the company’s New Drug Application (NDA) for sofosbuvir, a once-daily oral nucleotide analogue inhibitor for the treatment of chronic hepatitis C virus (HCV) infection. The FDA grants priority review status to drug candidates that may offer major advances in treatment over existing options. Gilead filed the NDA for sofosbuvir on April 8, 2013, and FDA has set a target review date under the Prescription Drug User Fee Act (PDUFA) of December 8, 2013.
The data submitted in this NDA support the use of sofosbuvir and ribavirin (RBV) as an all-oral therapy for patients with genotype 2 and 3 HCV infection, and for sofosbuvir in combination with RBV and pegylated interferon (peg-IFN) for treatment-naïve patients with genotype 1, 4, 5 and 6 HCV infection.
Sofosbuvir is an investigational product and its safety and efficacy have not yet been established.
About Gilead Sciences
Gilead Sciences is a biopharmaceutical company that discovers, develops and commercializes innovative therapeutics in areas of unmet medical need. The company’s mission is to advance the care of patients suffering from life-threatening diseases worldwide. Headquartered in Foster City, California, Gilead has operations in North America, Europe and Asia Pacific.
Sofosbuvir (formerly PSI-7977 or GS-7977) is an experimental drug candidate for the treatment of hepatitis C.[1] It was discovered at Pharmasset and then acquired for development by Gilead Sciences. It is currently in Phase III clinical trials.[2]
Sofosbuvir is a prodrug that is metabolized to the active antiviral agent 2′-deoxy-2′-α-fluoro-β-C-methyluridine-5′-monophosphate.[3]
Sofosbuvir is a nucleotide analogue inhibitor of the hepatitis C virus (HCV) polymerase.[4] The HCV polymerase or NS5B protein is a RNA-dependent RNA polymerase critical for the viral cycle.
Sofosbuvir is being studied in combination with pegylated interferon and ribavirin, with ribavirin alone, and with other direct-acting antiviral agents.[5] It has shown excellent clinical efficacy when used either with pegylated interferon/ribavirin or in interferon-free combinations. In particular, combinations of sofosbuvir with NS5A inhibitors, such as daclatasvir or GS-5885, have shown sustained virological response rates of up to 100% in people infected with HCV.[6]
Data from the ELECTRON trial showed that a dual interferon-free regimen of sofosbuvir plus ribavirin produced a 24-week post-treatment sustained virological response (SVR24) rate of 100% for previously untreated patients with HCV genotypes 2 or 3.[7][8]
Data presented at the 20th Conference on Retroviruses and Opportunistic Infections in March 2013 showed that a triple regimen of sofosbuvir, ledipasvir (formerly GS-5885), and ribavirin produced a 12-week post-treatment sustained virological response (SVR12) rate of 100% for both treatment-naive patients and prior non-responders with HCV genotype 1.[9]Gilead has developed a sofosbuvir + ledipasvir coformulation that is being tested with and without ribavirin.

Cubist Announces Submission of New Drug Application for Investigational Antibiotic Tedizolid for Treatment of Serious Skin Infections
LEXINGTON, Mass.–(BUSINESS WIRE)– Cubist Pharmaceuticals, Inc. today announced that it has submitted a New Drug Application (NDA) to the U.S. Food and Drug Administration (FDA) for approval of its investigational antibiotic tedizolid phosphate (TR-701). Cubist is seeking approval of tedizolid phosphate for the treatment of acute bacterial skin and skin structure infections (ABSSSI). Tedizolid phosphate is a once daily oxazolidinone being developed for both intravenous (I.V.) and oral administration for the treatment of serious Gram-positive infections, including those caused by methicillin-resistant Staphylococcus aureus (MRSA).
http://www.drugs.com/nda/tedizolid_131023.html
Emergence of bacterial resistance to known antibacterial agents is becoming a major challenge in treating bacterial infections. One way forward to treat bacterial infections, and especially those caused by resistant bacteria, is to develop newer antibacterial agents that can overcome the bacterial resistance. Coates et al. (Br. J. Pharmacol. 2007; 152(8), 1147-1154.) have reviewed novel approaches to developing new antibiotics. However, the development of new antibacterial agents is a challenging task. For example, Gwynn et al. (Annals of the New York Academy of Sciences, 2010, 1213: 5-19) have reviewed the challenges in the discovery of antibacterial agents.
Several antibacterial agents have been described in the prior art (for example, see PCT International Application Nos. PCT/US2010/060923, PCT/EP2010/067647, PCT/US2010/052109, PCT/US2010/048109, PCT/GB2009/050609, PCT/EP2009/056178 and PCT/US2009/041200). However, there remains a need for potent antibacterial agents for preventing and/or treating bacterial infections, including those caused by bacteria that are resistant to known antibacterial agents.
