Heptares Founder Richard Henderson Receives Nobel Prize in Chemistry 2017

Posted by fidest press agency su sabato, 7 ottobre 2017

londonLONDON and TOKYO/PRNewswire/ Heptares Therapeutics (“Heptares”), a wholly owned subsidiary of Sosei Group Corporation (“Sosei”; TSE Mothers Index: 4565), is delighted that one of its founders, Richard Henderson (MRC Laboratory of Molecular Biology, Cambridge, UK), was awarded the Nobel Prize in Chemistry 2017 together with Jacques Dubochet (University of Lausanne, Switzerland) and Joachim Frank (Columbia University, New York, USA) “for developing cryo-electron microscopy for the high-resolution structure determination of biomolecules in solution.”Cryo-electron microscopy (cryo-EM) is a technique for determining three-dimensional information about protein structures at the molecular level. Along with traditional methods for structure determination, such as x-ray crystallography and nuclear magnetic resonance spectroscopy, cryo-EM can reveal the structure of complex molecular assemblies to near atomic level. Detailed information, such as this, is expected to improve understanding of the structure and function tokyo-japanof proteins under investigation, and thereby advance the design of new drugs targeting specific proteins. Heptares is applying the techniques of cryo-EM to study G protein-coupled receptor (GPCR) protein complexes, the insights from which are helping to advance the discovery of potential new medicines.Malcolm Weir, CEO and co-founder Heptares, said: “We are delighted that Richard has received this most prestigious of awards. It is very well deserved and justified recognition of his outstanding contribution to science as a true pioneer of structural biology. His work on membrane protein structure in particular provided the inspiration and scientific foundation for Heptares’ work on GPCR structure-based drug design, and we continue to benefit enormously from his contributions. We would like to offer Richard and his fellow prize winners our warmest congratulations for this fantastic achievement.” Richard Henderson co-founded Heptares Therapeutics with Malcolm Weir, Fiona Marshall and Chris Tate in 2007.

Accidental discoveries that went boom

Posted by fidest press agency su mercoledì, 21 settembre 2016

Washington. Chemistry typically involves precise measurements and careful testing in order to get significant results. Yet several notable discoveries happened simply by accident — ultimately altering how society views science. Find out how several explosives and the beginnings of the Nobel prizes came to be in this second volume of accidental discoveries that changed the world. Check out this week’s Reactions video here: https://youtu.be/CjMEA7BVPpk.

Ormone della sazietà somministrato con un chewing gum

Sono state pubblicate dal Journal of medicinal chemistry le prime prove di validità della somministrazione orale, ipotizzandola, per esempio, mediante una gomma da masticare, dell’ormone Pyy in grado di bloccare la fame inducendo senso di sazietà. La molecola viene fisiologicamente rilasciata dall’organismo dopo un pasto, in quantità proporzionale alle calorie ingerite e anche dopo l’esercizio fisico. Tuttavia in molti soggetti obesi è stato notato che questo ormone non rispetta questa regola e anche dopo un pasto abbondante non viene prodotto a sufficienza. I ricercatori, guidati da Robert Doyle della Syracuse university, hanno somministrato Pyy endovena e hanno osservato la sua capacità di ridurre l’appetito, poi lo hanno legato alla vitamina B12, che funziona da carrier e somministrato per bocca. La vitamina trasporta l’ormone nell’intestino per essere poi assimilato ed entrare nel circolo sanguigno, superando così il processo digestivo che lo inattiva a livello dello stomaco. L’ipotesi è quindi quella di inserire una dose di Pyy-B12 in un chewing gum per creare un farmaco antifame da prendere subito dopo un pasto, che induca a mangiare meno al pasto successivo.J Med Chem. 2011 Nov 16.

The International Year of Chemistry

Posted by fidest press agency su mercoledì, 28 settembre 2011

Senator Lisa Murkowski of Alaska

Washington, By unanimous consent, the U.S. Senate adopted a resolution yesterday designating 2011 as the International Year of Chemistry (IYC). Senate Resolution 283 “recognizes the achievements made in the field of chemistry and the contributions of those achievements to the well-being of humankind…and provides solutions that successfully address global challenges involving safe food and water, alternate sources of energy, improved health and a healthy and sustainable environment.”
“Chemistry has long been one of the fundamental scientific drivers of innovation,” said Sen. Coons. “The Senate’s passage of this resolution celebrates the work of chemists around the world to advance the well-being of humankind, and notes the critical contribution science plays to our society. The jobs of tomorrow are being formulated in the labs of today, which is why continued support of advanced research and innovation is so important. As the holder of a chemistry degree and having worked for years at a science-based manufacturing company, I was proud to have led the effort in the Senate to dedicate 2011 as the International Year of Chemistry. I hope this designation encourages more students to choose careers in science and helps motivate the next generation of innovative chemists.” The resolution was co-sponsored by Sen. Jeff Bingaman (D-NM), Sen. Lisa Murkowski (R-AK), Sen. Mark Pryor (D-AR), and Sen. Debbie Ann Stabenow (D-MI). “This resolution supports the U.N.’s effort to educate children worldwide on the importance of chemistry,” said Sen. Murkowski. “It also brings recognition to the extraordinary contributions to science by Marie Curie, on the 100th anniversary of her second Nobel Prize.”
IYC 2011 is a global celebration of chemistry and its contributions to the world around us as officially designated by the United Nations. This worldwide initiative is being celebrated under the auspices of the United Nations Educational, Scientific and Cultural Organization (UNESCO) and the International Union of Pure and Applied Chemistry (IUPAC).

Nobel Prize in Chemistry

Posted by fidest press agency su venerdì, 8 ottobre 2010

Washington, Ei-ichi Negishi, Ph.D., who just shared the 2010 Nobel Prize in Chemistry, will lead a Chemical & Engineering News (C&EN) webinar Oct. 12 on  the discovery, development and application of the famed ZACA reaction. C&EN is the weekly newsmagazine of the American Chemical Society (ACS), the world’s largest scientific society. That landmark chemical reaction provides new ways of making medicines and other key products using green chemistry methods, which minimize or avoid the use of potentially toxic substances. ZACA stands for zirconium-catalyzed asymmetric carboalumination of alkenes. The webinar, sponsored by Aldrich Chemistry, will be broadcast live from Purdue University, West Lafayette, Ind., at 9:30 a.m. EDT as part of a the fifthannual two-day Negishi-Brown and Catalytic Asymmetric and Other Selective Syntheses (CAOSS) Lectures. Stu Borman, deputy assistant managing editor of C&EN, will moderate the session. The American Chemical Society is a nonprofit organization chartered by the U.S. Congress. With more than 161,000 members, ACS is the world’s largest scientific society and a global leader providing access to chemistry-related research through its multiple databases, peer-reviewed journals and scientific conferences. Its main offices are in Washington, D.C., and Columbus, Ohio.
