Small molecule bromodomain inhibitors: Extending the druggable genome

Bromodomains are modulators of protein-protein interactions essential for epigenetic mechanisms of transcriptional control. The recent disclosure of potent, selective, small molecule inhibitors of the BET bromodomain subfamily and their profound in vivo activity in several disease models suggests that the druggable genome should be extended to include this epi-reader target class. This chapter reviews the progress in bromodomain inhibitor drug discovery. The role of reader proteins in epigenetic gene regulation and the concept of the histone code are introduced. The therapeutic potential of bromodomain modulation in oncology, inflammation, metabolic and infectious disease is summarized. Methods of lead identification including use of phenotypic-, cell mechanistic-, biochemical- and fragment-based screens are described, as are selectivity considerations for this emerging target class. Difficulties in exploring this target class are also highlighted. Bromodomain chemical tractability is discussed using published examples, where SAR and the X-ray crystal structures exemplify how potency and selectivity can be achieved.

tert-Butyl Nitrite (TBN), a Multitasking Reagent in Organic Synthesis

The upsurge interest in the development of efficient methodologies for the construction of nitrogen-containing frameworks via the use of expedient reagents have been creating a renaissance in contemporary organic chemistry. In this perspective, tertbutyl nitrite (TBN) is an emerging building block. Due to its unique structural features, it shows differential reactivity under different reaction conditions. These diverse reactivities have resulted in the construction of a diverse array of complex N-containing molecules. The primary objective of the present review is to bring the latest findings of TBN in terms of its applications in reactions (oxidation, diazotization, nitrosation, nitration, oximation, N-synthon, and miscellaneous reactions) into the limelight. For simplicity and brevity, reactions in each section are explained with the mechanism of formation and selected examples are given.

Biphenylsulfonamide endothelin receptor antagonists. 4. Discovery of N-[[2?-[[(4,5-dimethyl-3-isoxazolyl)amino]sulfonyl]-4- (2-oxazolyl)[1,1?-biphenyl]-2-yl]methyl]-N,3,3-trimethylbutanamide (BMS-207940), a highly potent and orally active ETA selective antagonist

We have previously disclosed the selective ETA receptor antagonist N-(3,4-dimethyl-5-isoxazolyl)-4?-(2-oxazolyl)[1,1?- biphenyl]-2-sulfonamide (1, BMS-193884) as a clinical development candidate. Additional SAR studies at the 2?-position of 1 led to the identification of several analogues with improved binding affinity as well as selectivity for the ETA receptor. Following the discovery that a 3-amino-isoxazole group displays significantly improved metabolic stability in comparison to its 5-regioisomer, the 3-amino-isoxazole group was combined with the optimal 2?-substituent leading to 16a (BMS-207940). Compound 16a is an extremely potent (ETA Ki = 10 pM) and selective (80000-fold for ETA vs ETB) antagonist. It is also 150-fold more potent and >6-fold more selective than 1. The bioavailability of 16a was 100% in rats and the systemic clearance and volume of distribution are higher than that of 1. In rats, intravenous 16a blocks big ET pressor responses with 30-fold greater potency than 1. After oral dosing at 3 mumol/kg, 16a displays enhanced duration relative to 1.

Adsorption of oxazole and isoxazole on BNNT surface: A DFT study

The adsorption behavior of oxazole and isoxazole heterocycles over the (6,0) zigzag and (5,5) armchair boron nitride nanotube (BNNT) has been studied within the formalism of density functional theory (DFT). The adsorption energies, the frontier molecular orbital (FMO) analysis and the structural changes at the adsorption site are indicative of covalent adsorption on the zigzag BNNT surface, while the adsorption is physical in nature on the armchair BNNT surface. The role of solvent in improving the adsorption properties over the BNNT surface is elucidated by reoptimizing the structures in aqueous phase. The solvation energy is indicative of remarkable increase in the solubility of BNNTs after adsorption of heterocyclic rings. The Density of states (DOS) Plots, natural bond orbital (NBO) analysis and the quantum molecular descriptors (QMD) are witness to the substantial changes in the electronic properties of the BNNT systems following the attachment of these heterocycles with the tube surface. The study envisages the functionalization of the BNNT as well as its applicability as carrier of the drugs containing heterocyclic rings oxazole and isoxazole with marked sensitivity to the type of adsorbate and the adsorbent.

Impact of biogenic substrates on sulfamethoxazole biodegradation kinetics by Achromobacter denitrificans strain PR1

Pure cultures have been found to degrade pharmaceutical compounds. However, these cultures are rarely characterized kinetically at environmentally relevant concentrations. This study investigated the kinetics of sulfamethoxazole (SMX) degradation by Achromobacter denitrificans strain PR1 at a wide range of concentrations, from ng/L to mg/L, to assess the feasibility of using it for bioaugmentation purposes. Complete removal of SMX occurred for all concentrations tested, i.e., 150 mg/L, 500 mug/L, 20 mug/L, and 600 ng/L. The reaction rate coefficients (kbio) for the strain at the ng/L SMX range were: 63.4 ± 8.6, 570.1 ± 15.1 and 414.9 ± 124.2 L/gX SS·day), for tests fed without a supplemental carbon source, with acetate, and with succinate, respectively. These results were significantly higher than the value reported for non-augmented activated sludge (0.41 L/(g X SS·day) with hundreds of ng/L of SMX. The simultaneous consumption of an additional carbon source and SMX suggested that the energetic efficiency of the cells, boosted by the presence of biogenic substrates, was important in increasing the SMX degradation rate. The accumulation of 3-amino-5-methylisoxazole was observed as the only metabolite, which was found to be non-toxic. SMX inhibited the Vibrio fischeri luminescence after 5 min of contact, with EC50 values of about 53 mg/L. However, this study suggested that the strain PR1 still can degrade SMX up to 150 mg/L. The results of this work demonstrated that SMX degradation kinetics by A. denitrificans PR1 compares favorably with activated sludge and the strain is a potentially interesting organism for bioaugmentation for SMX removal from polluted waters.

Update 1 of: Destruction and detection of chemical warfare agents

The review describes many mainstream efforts by various chemical and biochemical laboratories, there are also many smaller sets of studies and single papers that investigate new systems undertaken in the hope that informative or useful results can be obtained. review describes many mainstream efforts by various chemical and biochemical laboratories, there are also many smaller sets of studies and single papers that investigate new systems undertaken in the hope that informative or useful results can be obtained families of materials, nanoscience, and enzymology continue to evolve naturally out of the continuing efforts of the research laboratories worldwide. Contamination of agents during their lifetime (synthesis, storage, unwanted deployment, and finally, destruction or decontamination) impacts human health and the environment. Systems based on microorganisms are essential to be included in a discussion of decontamination. New softer and polymer-based materials such as those at surfaces are probably more promising for a greater range of applications than rigid particles. A very important topic for the study of the decomposition of nerve agents and closely related compounds is still solid-phase surfaces. The most important consideration in protection is separating, and keeping separate, the toxic agent from personnel. Optimal personal protection has yet to be realized.
