NMR spectroscopy

Q.5.(c) In NMR spectroscopy, explain shift correlation spectra- COSY and its application in simplifying complex HNMR spectra.

Ans.5. (c) COSY (Correlation SpectroscopY): COSY is a method of two-dimensional spectroscopy and also known as H-H correlation spectroscopy.  In a COSY experiment, the chemical shift range of the proton spectrum is plotted on both axes.

IBM and  Teva pharma announce a significant expansion of their existing global e-Health alliance with a focus on two key healthcare challenges: the discovery of new treatment options and improving chronic disease management. Both projects will run on the IBM Watson Health Cloud.

Medtronic plc announced the U.S. Food and Drug Administration (FDA) approval and U.S. launch of the CoreValve(TM) Evolut(TM) R 34 mm valve-the largest sized transcatheter aortic valve replacement (TAVR) system available in the U.S. The new Evolut R 34 mm valve is approved for severe aortic stenosis patients who are at high or extreme risk for surgery with an annulus size ranging from 26-30 mm. This large valve segment is estimated to account for approximately 25-30 percent of the eligible global TAVR patient population. Previously, some of these patients were unable to receive a TAVR due to the larger size of their native diseased aortic valve.

Daiichi Sankyo, Inc. and Inspirion Delivery Sciences LLC (Inspirion) have entered into a strategic collaboration agreement in the US to commercialize FDA-approved MorphaBond (morphine sulfate) extended-release tablets, CII. The agreement also provides Daiichi Sankyo, Inc. with the rights to commercialize a separate investigational Inspirion compound in the US, if approved by the US Food and Drug Administration (FDA).

AstraZeneca, a global, science-led biopharmaceutical company, announced positive results from the phase III SOLO-2 trial designed to determine the efficacy of Lynparza (olaparib) tablets (300mg twice daily) as a monotherapy for the maintenance treatment of platinum-sensitive relapsed, BRCA-mutated ovarian cancer. Results from the trial demonstrate a clinically-meaningful and statistically-significant improvement of progression-free survival (PFS) among patients treated with Lynparza compared to placebo and provide additional evidence to support the potential use of Lynparza in this patient population.
