During the past decade, decreasing the attrition rate of drug development candidates reaching the market has become one of the major challenges in pharmaceutical research and drug development (R&D). To facilitate the decision-making process, and to increase the probability of rapidly finding and developing high-quality compounds, a variety of multiparametric guidelines, also known as rules and ligand efficiency (LE) metrics, have been developed. However, what are the 'best' descriptors and how far can we simplify these drug-likeness prediction tools in terms of the numerous, complex properties that they relate to?...

BACKGROUND: Outbreaks of health care-associated infections (HAIs) caused by Burkholderia cepacia complex (Bcc) have been associated with medical devices and water-based products. Water is the most common raw ingredient in nonsterile liquid drugs, and the significance of organisms recovered from microbiologic testing during manufacturing is assessed using a risk-based approach. This incident demonstrates that lapses in manufacturing practices and quality control of nonsterile liquid drugs can have serious unintended consequences...

Lead structure discovery mainly focuses on the identification of noncovalently binding ligands. Covalent linkage, however, is an essential binding mechanism for a multitude of successfully marketed drugs although discovered by serendipity in most cases. We present a concept for the design of fragments covalently binding to proteases. Covalent linkage enables fragment binding unrelated to affinity to shallow protein binding sites and at the same time allows differentiated targeted hit verification and binding location verification through mass spectrometry...

Chirally pure molecules or enantiomers are non-superimposable mirror images of each other with a chiral center (such as carbon, sulphur, nitrogen or phosphorous atom). An equimolar mixture of enantiomers forms a racemate. Chirally pure molecules (single enantiomers) are important in the field of drug discovery as the drug targets such as enzymes and receptors are enantioselective in nature. Clinical studies have demonstrated that chirally pure drugs exhibit different pharmacokinetic and metabolic profiles, reduced adverse events, improved safety profiles and similar therapeutic activity at lowered drug dosage as compared with the racemate in many therapeutic areas...

In the last decades the pharmaceutical market has experienced an increase in the number of therapeutic proteins. The high activity and selectivity of these macromolecules is often achieved at the expense of complex structures, which exhibit several biophysical properties that must be carefully controlled and optimized for the successful development of these drugs as well as for guaranteeing their quality and safety. This need has motivated the application of a variety of biophysical techniques to analyze properties of therapeutic proteins and protein solutions including interactions, aggregation, solubility, viscosity and thermal stability...

<p>BACKGROUND: Fractional photothermolysis (FP) is a popular treatment option for photodamaged skin and addresses shortcomings of ablative skin resurfacing and nonablative dermal remodeling. Previous studies have demonstrated that FP using the 1550nm wavelength has led to improvement of ultrastructural changes and clinical effects associated with photodamaged skin in the deeper dermal structures, while treatment with the 1927nm wavelength has shown clinical effects in the superficial dermis. Both wavelengths produce precise microscopic treatment zones (MTZs) in the skin...

BACKGROUND: Rheumatoid arthritis (RA) is a morbid, mortal and costly condition without a cure. Treatments for RA have expanded over the last two decades and direct medical costs may differ by types of treatments. There has not been a systematic literature review since the introduction of new RA treatments, including biologic disease modifying anti-rheumatic drugs (bDMARDs). METHODS: We conducted a systematic literature review with meta-analysis of direct medical costs associated with RA cared for in the US since the marketing of the first bDMARD...

Gene-based therapy is one of essential therapeutic strategies for precision medicine through targeting specific genes in specific cells of target tissues. However, there still exist many problems that need to be solved, such as safety, stability, selectivity, delivery, as well as immunity. Currently, the key challenges of gene-based therapy for clinical potential applications are the safe and effective nucleic acid drugs as well as their safe and efficient gene delivery systems. In this review, we first focus on current nucleic acid drugs and their formulation in clinical trials and on the market, including antisense oligonucleotide, siRNA, aptamer, and plasmid nucleic acid drugs...

Indole, indazole or azaindole based synthetic cannabinoids (SCs), bearing a cumyl substituent are a widespread, recreationally used subgroup of new psychoactive substances (NPS). The latest cumyl-derivative, CUMYL-PEGACLONE, emerged in December 2016 on the German drug market. The substance features a novel γ-carboline core structure, which is most likely synthesized to bypass generic legislative approaches to control SCs by prohibiting distinct core structures. Using liquid chromatography tandem mass spectrometry and liquid chromatography high resolution mass spectrometry techniques, the main in vivo phase I metabolites of this new substance were detected...
