Non-cytochrome P450-mediated bioactivation and its toxicological relevance

The bioactivation of drugs is often associated with toxicological outcomes; however, for most cases, the causal relationship between bioactivation and toxicity is not well established despite extensive research that attempts to elucidate the mechanisms leading to the formation of chemically reactive species, presumably the initial step towards adverse reactions. Due to rapid advancement in the research of cytochrome P450s (CYPs) and the prevalence of CYP involvement in the metabolic clearance of pharmaceuticals, CYP-mediated bioactivation is widely investigated and reviewed, while non-CYP-mediated bioactivation has not been emphasized. The widespread use of metabolic stability screening in drug discovery, however, has led to the identification of new chemical entities that rely on non-CYP enzymes for clearance, and the number of drugs that undergo metabolism via these enzymes has increased. Non-CYP enzymes can be divided into four general categories according to their enzymatic function, namely, oxidative, reductive, conjugative and hydrolytic. The aim of this review is to complement the existing literature on CYP-mediated metabolism by focusing on bioactivation mediated non-CYP enzymes and provide representative examples in each category.

Photocycloaddition of aromatic and aliphatic aldehydes to isoxazoles: Cycloaddition reactivity and stability studies

The first photocycloadditions of aromatic and aliphatic aldehydes to methylated isoxazoles are reported. The reactions lead solely to the exo-adducts with high regio- and diastereoselectivities. Ring methylation of the isoxazole substrates is crucial for high conversions and product stability. The 6-arylated bicyclic oxetanes 9a-9c were characterized by X-ray structure analyses and showed the highest thermal stabilities. All oxetanes formed from isoxazoles were highly acid-sensitive and also thermally unstable. Cleavage to the original substrates is dominant and the isoxazole derived oxetanes show type T photochromism.

Bromodomains: Structure, function and pharmacology of inhibition

Bromodomains are epigenetic readers of histone acetylation involved in chromatin remodeling and transcriptional regulation. The human proteome comprises 46 bromodomain-containing proteins with a total of 61 bromodomains, which, despite highly conserved structural features, recognize a wide array of natural peptide ligands. Over the past five years, bromodomains have attracted great interest as promising new epigenetic targets for diverse human diseases, including inflammation, cancer, and cardiovascular disease. The demonstration in 2010 that two small molecule compounds, JQ1 and I-BET762, potently inhibit proteins of the bromodomain and extra-terminal (BET) family with translational potential for cancer and inflammatory disease sparked intense efforts in academia and pharmaceutical industry to develop novel bromodomain antagonists for therapeutic applications. Several BET inhibitors are already in clinical trials for hematological malignancies, solid tumors and cardiovascular disease. Currently, the field faces the challenge of single-target selectivity, especially within the BET family, and of overcoming problems related to the development of drug resistance. At the same time, new trends in bromodomain inhibitor research are emerging, including an increased interest in non-BET bromodomains and a focus on drug synergy with established antitumor agents to improve chemotherapeutic efficacy. This review presents an updated view of the structure and function of bromodomains, traces the development of bromodomain inhibitors and their potential therapeutic applications, and surveys the current challenges and future directions of this vibrant new field in drug discovery.

DNA Encoded Libraries: A Visitor’s Guide

In 1992, Brenner and Lerner hypothesized that individual chemical transformations could be encoded in DNA, allowing the rapid synthesis and screening of large collections of small molecules. Since their report, huge investments into the development of the DNA encoded library (DEL) technology have enabled the acceleration of the drug discovery process especially early phase discovery undertakings such as target validation and hit identification. As DEL lies at the nexus between chemistry and biology, there is an increasing need to expand the toolboxes of both organic transformations and biological methods. However, the myriad of techniques and reactions already reported can be difficult to digest for practitioners whose expertise resides outside the realm of DEL. This review therefore focuses on a stepwise presentation of DEL from the basic concepts to newest developments. The presentation includes the history, fundamentals, and successes of DEL, different methods for DEL synthesis and affinity selection, the conventional transformations, and finally the latest developments from a synthetic organic perspective.

Dust evolution, a global view: II. top-down branching, nanoparticle fragmentation and the mystery of the diffuse interstellar band carriers

The origin of the diffuse interstellar bands (DIBs), one of the longest-standing mysteries of the interstellar medium (ISM), is explored within the framework of The Heterogeneous dust Evolution Model for Interstellar Solids (THEMIS). The likely nature of the DIB carriers and their evolution is here explored within the framework of the structures and sub-structures inherent to doped hydrogenated amorphous carbon grains in the ISM. Based on the natural aromatic-rich moieties (asphaltenes) recovered fromcoal and oil, the likely structure of their interstellar analogues is investigated within the context of the diffuse band problem. It is here proposed that the top-down evolution of interstellar carbonaceous grains, and, in particular, a-C(:H) nanoparticles, is at the heart of the formation and evolution of the DIB carriers and their associations with small molecules and radicals, such as C2, C3, CH and CN. It is most probable that the DIBs are carried by dehydrogenated, ionized, hetero-cyclic, olefinic and aromatic-rich moieties that form an integral part of the contiguous structure of hetero-atomdoped hydrogenated amorphous carbon nanoparticles and their daughter fragmentation products.Within this framework, it is proposed that polyene structures in all their variants could be viable DIB carrier candidates.

Exploring Green Solvents Associated to Pd/C as Heterogeneous Catalyst for Direct Arylation of Heteroaromatics with Aryl Bromides

Metal residues are certainly one of the major sources of contamination of products in metal-catalyzed direct arylation reactions. We found that the use of only 1 mol% of the heterogeneous catalyst Pd/C promotes very efficiently the direct arylations of most heteroaromatics. In the presence of this catalyst and potassium acetate as the base, the direct arylation of thiophenes, furans, pyrroles, thiazoles, imidazoles or isoxazoles, using aryl bromides as coupling partners, proceeds highly regioselectively and in moderate to very high yields. With several heteroarenes both electron-deficient and electron-rich aryl bromides were tolerated; moreover, with the most reactive heteroarenes, the Pd/C catalyst tolerated green solvents such as diethyl carbonate, 3-methylbutan-1-ol and pentan-1-ol, affording a synthetic scheme with low environmental impact. (Figure presented.).
