A highly efficient, recyclable and ligand-free protocol was developed for the Suzuki coupling reaction of potassium aryltrifluoroborates in water.
A highly efficient, recyclable and ligand-free protocol was developed for the Suzuki coupling of aryl halides with potassium aryltrifluoroborates in water using Pd(OAc)2 as a catalyst and Na2CO3 as a base in air. The presence of poly(ethylene glycol) (PEG) was crucial to the efficiency of the protocol. A wide range of functional groups were tolerated under the optimized conditions. Furthermore, the protocol could be extended to the Suzuki coupling of heteroaryl halides with potassium phenyltrifluoroborate, delivering the desired products in moderate to excellent yields. After simple workup, Pd(OAc)2–H2O–PEG could be recycled at least eight times without significant loss in activity.

The future of drug discovery for neglected and tropical diseases will depend on the ability of those working in the area to collaborate and will require sustained resourcing and focus
Neglected and tropical diseases affect a large proportion of the world’s population and impose a huge economic and health burden on developing countries. Despite this, there is a dearth of safe, effective, suitable medications for treatment of these diseases, largely as a result of an underinvestment in developing new drugs against these diseases by the majority of research-based pharmaceutical companies. In the past 12 years, the situation has begun to improve with the emergence of public-private product development partnerships (PDPs), which foster a collaborative approach to drug discovery and have established strong drug development pipelines for neglected and tropical diseases. Some large pharmaceutical companies have also now established dedicated research sites for developing world diseases and are working closely with PDPs on drug development activities. However, drug discovery in this field is still hampered by a lack of sufficient funding and technological investment, and there is a shortage of the tools, assays, and well-validated targets needed to ensure strong drug development pipelines in the future. The availability of high-quality chemically diverse compound libraries to enable lead discovery remains one of the critical bottlenecks. The pharmaceutical industry has much that it can share in terms of drug discovery capacity, know-how, and expertise, and in some cases has been moving towards new paradigms of collaborative pre-competitive research with the PDPs and partners. The future of drug discovery for neglected and tropical diseases will depend on the ability of those working in the area to collaborate together and will require sustained resourcing and focus.

Boston Scientists Develop New Probiotic Supplement to Manage Weight

Boston Scientists Develop New Probiotic Supplement to Manage Weight

(Boston) – Healthcare experts continue to regard probiotics as one of the most powerful tools in the management of everything from constipation and bloating to diarrhea and skin health.

Historically, yogurt has been a primary source of probiotics, but yogurt products loaded with sugar have their own health implications for the tens of millions of Americans who are trying to lose weight. Sales of the healthier Greek-style yogurt were up 50% in 2012, showing that Americans are looking for healthier probiotic options. Unfortunately, even most Greek yogurt is loaded with sugar and calories.

So, how is the weight-conscious American supposed to get their probiotics?
