Christopher C McAtee, Paul S Riehl, Corinna S Schindler
Polycyclic aromatic hydrocarbons are important structural motifs in organic chemistry, pharmaceutical chemistry, and materials science. The development of a new synthetic strategy toward these compounds is described based on the design principle of iron(III)-catalyzed carbonyl-olefin metathesis reactions. This approach is characterized by its operational simplicity, high functional group compatibility, and regioselectivity while relying on FeCl3 as an environmentally benign, earth-abundant metal catalyst. Experimental evidence for oxetanes as reactive intermediates in the catalytic carbonyl-olefin ring-closing metathesis has been obtained...

Breath analysis not only holds great potential for the development of new non-invasive diagnostic methods, but also for the identification and follow up of drug levels in breath. This is of interest for both, forensic and medical science. On the one hand, the detection of drugs of abuse in exhaled breath - similar to the well-known breath alcohol tests - would be highly desirable as an alternative to blood or urine analysis in situations such as police controls for drugged driving. The noninvasive detection of drugs and their metabolites is thus of great interest in forensic science, especially since marijuana is becoming legalized in certain parts of the U...

BACKGROUND: Glaucoma is a leading cause of irreversible blindness worldwide and the second most common cause of blindness after cataracts. The primary treatment for glaucoma aims to lower intraocular pressure (IOP) with the use of topical medicines. Topical medication instillation techniques, such as eyelid closure and nasolacrimal occlusion when instilling drops, have been proposed as potential methods to increase ocular absorption and decrease systemic absorption of the drops. OBJECTIVES: To investigate the effectiveness of topical medication instillation techniques compared with usual care or another method of instillation of topical medication in the management of glaucoma or ocular hypertension...

BACKGROUND: Clinical research affecting how doctors practice medicine is increasingly sponsored by companies that make drugs and medical devices. Previous systematic reviews have found that pharmaceutical-industry sponsored studies are more often favorable to the sponsor's product compared with studies with other sources of sponsorship. A similar association between sponsorship and outcomes have been found for device studies, but the body of evidence is not as strong as for sponsorship of drug studies...

Cyclodextrin (CD) is a subset of the macrocyclic structural class, which is an important class of small organic agents that are useful functional excipients. They have wide range application possibilities in different fields of sciences such as material preparation, medicine, analytical chemistry, and separation processes. They are used widely in pharmaceutical formulations and drug delivery for increasing the water solubility of low soluble drugs and drug candidates. Due to the ring structure, they behave differently than smaller molecules and may be capable of hitting new classes of targets...

This paper examines how the Weizmann Institute of Science has been telling the story of the successful commercialization of a scientific invention, through its corporate communication channels, from the early 1970s to today. The paper aims to shed light on the transformation processes by which intellectual-property-based commercialization activities have become widely institutionalized in universities all over the world, and on the complexities, ambiguities and tensions surrounding this transition. We look at the story of the scientific invention of Copolymer-1 at the Weizmann Institute of Science and its licensing to Teva Pharmaceutical Industries, which subsequently developed the highly successful drug Copaxone for the treatment of multiple sclerosis...

The category of disease-modifying anti-rheumatic drugs (DMARDs) emerged in the 1970s to describe drugs capable of altering the long-term destructive course of arthritis. It became a core concept in rheumatology's reorientation towards pharmaceuticals in the late twentieth century. By examining the earliest use of the term "disease-modifying" in scientific publications, this paper identifies the drugs that the category described when it first emerged. Leaning on systematic reviews of each of these drugs towards the end of their career in rheumatology, it then establishes that posterity would not recognize any of these early DMARDs as capable of altering the long-term course of the disease...

BACKGROUND: Since the recombinant protein was discovered, it has become more popular in many aspects of life science. The value of global pharmaceutical market was $87 billion in 2008 and the sales for industrial enzyme exceeded $4 billion in 2012. This is strong evidence showing the great potential of recombinant protein. However, native genes introduced into a host can cause incompatibility of codon usage bias, GC content, repeat region, Shine-Dalgarno sequence with host's expression system, so the yields can fall down significantly...

Nanotechnology enables the creation of delivery vehicles able to overcome physiologically imposed barriers, allowing new approaches for reducing the unwanted side effects of systemic delivery of drug, increasing targeting efficiency and so improving therapy efficacy. Owing to the considerable advances in material sciences and pharmaceutics, a broad range of different inorganic or organic drug nanocarriers have been developed. Furthermore, researchers have shown that the combination of inorganic and organic chemistries in one single material, named metal-organic framework (MOF), offers structural designability at the molecular level together with tunable porosity and chemical functionalisability...

REVIEW
Naveen K Thakral, Ron C Kelly
While screening the counter-ions for salt selection for an active pharmaceutical substance, there is often an uncertainty about disproportionation of the salt and hence physical stability of the final product formulation to provide adequate shelf life. Several examples of disproportionation reactions are reviewed to explain the concepts of pHmax, microenvironmental pH, and buffering capacity of excipients and APIs to gain mechanistic understanding of disproportionation reaction. Miscellaneous factors responsible for disproportionation are examined...
