G-Protein-Coupled Receptors are the largest gene families in the human genome and, rightfully so, have become the leading molecular target in 2008. In 2009 SBS April meeting in Lille, France, followed-up with screening trends report stating that  “GPCRs are expected to replace protein kinases as the most common molecular target used by HTS laboratories.”

GPCRs are the largest family of cell surface receptors being integral to the number of cellular and physiological functions, including light sensing, smell, appetite control, insulin secretion, and blood pressure modulation. These receptors generally have a seven-membrane spanning alpha-helical topography, and while these receptors are similar in overall structure and function, they differ in key amino acid residues. The potential for this super family of receptors to reveal small molecule modulators of a significant biological function has been responsible for the focus of intense drug discovery efforts.

TimTec GPCR Ligands library is called ActiTarg-G. It currently counts 2,300 molecules available in various formatting options, and can be delivered in vials or in 96 or 384-well plates.  ActiTarg-G is the set of diverse molecules that contain chemical lattices present in compounds reported in the technical or patent literature to possess GPCR-ligand properties.

The packing’s unique geometric shape was developed in our chemical R&D laboratories for the purification of deuterated solvents and solvent recovery. Liquid does not pool irregardless of packing orientation. The surface is completely inert to polar and non-polar solvents, acids and bases, thereby eliminating any possible metal, organo-metalic, or monomer contamination as when using other packing materials. Due to the inert nature of PFE, cleaning and drying the packing for later use is easy and straight forward.

As an example of its distillation efficiency, we were able to produce 99.9% atom D2O from water using regular types of distillation columns and receivers. We have also distilled organic solvents to 99.99% purity and have recycled these for our own use. If you are interested in solvent recovery, whether for HPLC, HPLC-NMR, wet chemistry or other use, Norell’s PFE column packing is the leading product of choice.

“A critical goal of biomedical research is to transform discoveries into preventions, treatments, and cures,” said NIH Director Francis S. Collins, M.D., Ph.D. “By working together, CTSAs are removing barriers to research, training new generations of clinical and laboratory research teams, and providing them with the equipment and resources they need.”

Now in its fourth year, the CTSA consortium has generated resources that transform the research and training environment to enhance the efficiency and quality of clinical and translational research. Examples include a Web-based national recruitment registry that connects researchers with volunteers interested in participating in clinical studies, establishing public-private partnerships, and a portal that connects researchers with potential investigational drugs that may be useful in new ways.

The 2010 CTSAs expand consortium representation in new areas including New Mexico, Virginia and the District of Columbia, growing the consortium to 55 member institutions. The nine new institutions are:

Children’s National Medical Center, Washington, D.C.
Georgetown University with Howard University, Washington, D.C.
Medical College of Wisconsin, Milwaukee
University of California, Irvine
University of California, San Diego
University of Massachusetts, Worcester
University of New Mexico Health Sciences Center, Albuquerque
University of Southern California, Los Angeles
Virginia Commonwealth University, Richmond

Even with several therapies available to treat Alzheimer’s disease, there still is a significant gap between the onset of the disease and point at which treatment actually begins.  This treatment gap is directly tied to the challenges in diagnosing the disease early, before the significant loss of memory, cognition, and activities of daily living.  Patients, doctors, caregivers, and the pharmaceutical industry, are looking for and demanding a solution to this problem.

Neuronetrix’ COGNISION™ System will, for the first time, directly detect the abnormal cognitive effects of Alzheimer’s disease!  This will facilitate an earlier and more accurate diagnosis than is currently available.  Physicians will use the COGNISION™ test to determine which patients would benefit from the available drug treatments.  The system can also be used to monitor the efficacy of the prescribed therapy.

With the aging of America and the proliferation of new Alzheimer’s therapies, the market for Alzheimer’s screening could approach several billion dollars per year in the United States alone.

Following the validation of the COGNISION™ System for Alzheimer’s disease, Neuronetrix will expand into other neurodiagnostic markets such as ADHD, dyslexia, and depression.

Lipinski’s rule-of-five analysis
Christopher Lipinski’s rule-of-five analysis helped to raise awareness about properties and structural features that make molecules more or less drug-like. The guidelines were quickly adopted by the pharmaceutical industry as it helped apply ADME considerations early in preclinical development and could help avoid costly late-stage preclinical and clinical failures. The guidelines predict that poor absorption or permeation of a orally administered compound are more likely if the compound meets the following criteria:

* Molecular mass greater than 500 Da
* High lipophilicity (expressed as cLogP greater than 5)
* More than 5 hydrogen bond donors
* More than 10 hydrogen bond acceptors

Biological safety cabinets (BSCs) are specialized work areas that provide protection to users/operators and/or samples. BSCs are categorized as Class I, Class II or Class III, depending on their construction, airflow characteristics and exhaust systems. These classifications are based on each BSC’s suitability for samples at various biosafety levels. Class I and Class II cabinets handle Biosafety Levels 1, 2 and 3 (low to moderate risk), while Class III BSCs are intended for use with Biosafety Level 4 agents (high risk).

BSCs are distinct from other safety enclosures. Laboratory fume hoods pull air over the work item and out into the environment through a vent, whereas controlled atmosphere glove boxes are completely enclosed, protecting both users and samples through an airtight barrier. A distinguishing component of BSCs is their use of high-efficiency particle air (HEPA) filters, which scrub effluent between 99.5 percent and 99.99 percent of airborne particles, or at least 99.97 percent of particles larger than 3 microns.

Class distinctions

Class I BSCs protect personnel and the environment only. Samples are vulnerable because workspace air is swept over them before filtration and venting. Class II cabinets represent a broad category, with varying capabilities that are further subdivided into categories A1, A2, B1 and B2. The main differentiator between Class I and Class II BSCs is that Class II cabinets employ a HEPA-filtered, vertical, unidirectional airflow within the work area. Class III BSCs, which provide the highest level of protection to both workers and samples, are reserved for highly contagious or virulent biological samples.

Class II A2 cabinets are by far the most common BSCs in use today, comprising about 95 percent of installations, according to David Phillips, technical applications specialist at Thermo Scientific (Asheville, N.C.).

Class II cabinets have open fronts. Workers are protected by the steady vertical airflow. An ongoing controversy for specifying certain Class II cabinet types involves NSF Standard 49, which states that Class II A2 and B2 cabinets are designed to handle “minute” amounts of toxic chemicals and radionuclides. “But nobody has defined the term ‘minute’ quantitatively,” admits Phillips, who works on the NSF joint committee that determines BSC specifications.

To satisfy whatever that requirement might be, and to err on the side of caution, most laboratories automatically specify the use of Class II B2 cabinets, which Phillips describes as “complex, infrastructure sensitive and 10 times trickier to run” than Class II A2 cabinets. “A lot of people get stuck with B2s, but half of them should never have been installed. Users would be much better served by canopied A2 cabinets.”

Jim Hunter, senior project engineer at Labconco (Kansas City, Mo.), suggests using B-type cabinets in situations where workers are consistently working with volatile toxic agents, isotopes or anticancer drugs that you don’t want coming back into the lab. Otherwise, the acquisition and operating costs are simply not worth it. “B cabinets cost a lot of money and use a lot of energy. Unfortunately, architects assume a B cabinet is always better because it’s more expensive or because the letter ‘B’ comes after ‘A’ in the alphabet. All too often they simply override a customer’s decision on which type of cabinet to purchase,” says Hunter.

As a former certifier of BSCs, Phillips has a unique perspective on the evolution of these cabinets. In the past, he says, cabinets were commodities that barely differed as one considered the product offerings of numerous vendors. “They basically all looked like battleships,” he says. Beginning in the 1990s, cabinets began incorporating ergonomic designs that allowed operators to move forward and backward in comfort. Enclosures became brighter and air-handling systems quieter (through the adoption of DC motors and computer-controlled airflow compensation). “Cabinets evolved from being cookie- cutter-type products to having more choices and options. It’s a really fun time to be in this industry,” says Phillips.

One improvement affecting both operating costs and the environment is energy consumption. Older-model BSCs were energy hogs, but today’s units are downright miserly. Phillips recalls an event at the University of Michigan, where one of his Thermo Fisher colleagues was accused of low-balling the power consumption of a Thermo Fisher BSC. The assembled scientists were forced to eat their words after they tested the product and measured its energy usage. The result was a paper you can find at http:// bit.ly/N9bwz.

Environmental concerns have become a huge factor in BSC purchases, according to John Peters, assistant marketing director at Nuaire (Plymouth, Minn.). “Customers look for energy efficiency as well as total cost of ownership, the life of HEPA filters and the types of motors used to drive the air handlers,” he explains. Unlike many other laboratory products, purchasers of BSCs must perform their own due diligence, as no third-party organizations provide energyefficiency ratings for cabinets.
