In eukaryotes, many translation inhibitors have been widely used as bioprobes to evaluate the contribution of translation to signaling pathways and cellular functions. Several types of translation inhibitors are also known to trigger the activation of the mitogen-activated protein kinase superfamily in an intracellular mechanism called ribotoxic stress response. This perspective focuses on the biological properties of recently identified translation inhibitors that trigger ribotoxic stress response, particularly glutarimides as well as triene-ansamycins.

Both viscoelastic and plastic properties were investigated on random copolymers of methylmethacrylate (MMA) and N-methyl-glutarimide (GIM) in the range 0-76 mol%. All the measurements were performed on samples quenched from the melt in order to break free from physical aging effects. Dynamic mechanical experiments were performed at very low deformation and temperatures ranging from -150C up to the glass transition temperature (Tg) region. Increase in GIM amount improves the thermomechanical stability of the copolymers, as revealed by the increase of both Tg and alpha relaxation temperature. In the beta relaxation region, the E? loss peak first decreases in amplitude with increasing GIM content and then broadens further and finally spreads out till the onset of the alpha peak at the largest GIM amounts. A quantitative analysis of the beta relaxation phenomena was performed by considering the loss compliance J? instead of the loss modulus E?. It turns out that in the low temperature range (-80C-0C) the mechanical damping associated with the MMA motions is stronger for MMA-GIM than for MMA-MMA linkages; in addition, the mechanical damping associated with the motions of the GIM units is very low. By contrast, in the high temperature range (30C to about 100C), the mechanical damping associated with the MMA motions drops with increasing GIM amount, whereas a significant damping coming from the GIM units is observed. These results suggest that the beta relaxation would mainly consist of MMA isolated motions at low temperature and of cooperative motions at higher temperature, involving the MMA units at GIM amounts lower or equal to 58 mol% and the GIM units at higher GIM content. The stress-strain curves were determined at low strain rate (2×10-3 s-1) and temperatures ranging from -120C to Tg. Analysis of the plastic deformation region shows that the yield stress decreases with increasing GIM amount at low temperatures. The opposite trend shows up on the high temperature side of the beta relaxation, where strain softening peaks at intermediate GIM amounts. As a plausible explanation, the cooperative beta motions, whenever they exist, are suspected to be responsible for the decrease of both yield stress and strain softening. These conclusions agree well with those of a previous study on methylmethacrylate-co-maleimide copolymers. They are also consistent with our earlier identification of the microdeformation mechanisms involved in the stretching of methylmethacrylate-co-N-methylglutarimide thin films.

This paper deals with the mechanical properties (plastic deformation, micromechanism of deformation, fracture) of various amorphous polymers: poly(methyl methacrylate) and its maleimide and glutarimide copolymers, bisphenol A (and/or tetramethyl bisphenol A) polycarbonate, and aryl-aliphatic copolyamides. First, the required background on molecular characteristics, micromechanisms of deformation and fracture characterisation is recalled. Then, the results are discussed for each polymer series, considering information obtained on the motions involved in secondary transitions (mostly beta transitions) analysed in a previous paper. The importance of the cooperative motions occurring in the high temperature part of the transition is unambiguously pointed out. Furthermore, in glutarimide copolymers, as well as in aryl-aliphatic copolyamides, it is shown that the dependence of toughness on the entanglement density fails and only the consideration of cooperative a?transition motions can consistently account for the results. Finally, concerning the change of strain softening with increasing temperature, two opposite behaviours are observed for polymers in which beta transitions result, on the one hand from side-group motions (strain softening decreases) and on the other hand from certain main-chain units (strain softening increases). Two different mechanisms have been proposed, based on a softening of the polymer medium by a? transition motions associated with either an intramolecular cooperativity (in the first case), or an intermolecular cooperatively (in the second case) of these motions. Thus, combination of the results of the analysis of the relation of chemical structure to beta transition motions with the present conclusions yields a molecular description of the whole set of behaviours involved in the mechanical properties of amorphous polymers, till fracture.

In this report, a palladium-catalyzed redox-relay Heck process to access optically active alkenylated alpha,beta-unsaturated lactams is described. Under mild reaction conditions, electron-deficient alkenyl triflates and electron-rich alkenyl iodonium salts undergo enantioselective and site-selective coupling with enelactams to deliver the products in high yields and excellent enantioselectivities. Furthermore, the products allow facile access to natural products such as (+)-calvine and (+)-2-epicalvine in addition to the bioactive molecule aza-goniothalamin.

Time span of literature covered: 2010-2018 The genome mining of streptomycetes has revealed their great biosynthetic potential to produce novel natural products. One of the most promising exploitation routes of this biosynthetic potential is the refactoring and heterologous expression of corresponding biosynthetic gene clusters in a panel of specifically selected and optimized chassis strains. This article will review selected recent reports on heterologous production of natural products in streptomycetes. In the first part, the importance of heterologous production for drug discovery will be discussed. In the second part, the review will discuss recently developed genetic control elements (such as promoters, ribosome binding sites, terminators) and their application to achieve successful heterologous expression of biosynthetic gene clusters. Finally, the most widely used Streptomyces hosts for heterologous expression of biosynthetic gene clusters will be compared in detail. The article will be of interest to natural product chemists, molecular biologists, pharmacists and all individuals working in the natural products drug discovery field.

Pomalidomide is an immunomodulatory drug and the dosage of 4 mg per day taken orally on days 1-21 of repeated 28-day cycles has been approved in the European Union and United States to treat patients with relapsed/refractory multiple myeloma. Because pomalidomide is extensively metabolized prior to excretion, a total of 32 subjects (8 healthy subjects in group 1; 8 subjects with severe hepatic impairment in group 2; 8 subjects with moderate hepatic impairment in group 3; and 8 subjects with mild hepatic impairment in group 4) were enrolled in a multicenter, open-label, single-dose study to assess the impact of hepatic impairment on pomalidomide exposure. Following administration of a single oral dose of 4-mg pomalidomide, the geometric mean ratios of pomalidomide total plasma exposures (AUC) were 171.5%, 157.5%, and 151.2% and the geometric mean ratios of pomalidomide plasma peak exposures (Cmax) were 75.8%, 94.8%, and 94.2% for subjects with severe, moderate, or mild hepatic impairment, respectively, versus healthy subjects. Pomalidomide administered as a single oral 4-mg dose was safe and well tolerated by healthy subjects and subjects with severe, moderate, or mild hepatic impairment. Based on the pharmacokinetic results from this study, the pomalidomide prescribing information approved by the US Food and Drug Administration recommends for patients with mild or moderate hepatic impairment (Child-Pugh classes A or B), a 3-mg starting daily dose (25% dose reduction) and for patients with severe hepatic impairment (Child-Pugh class C), a 2-mg starting daily dose (50% dose reduction).

The effect of 3-methoxybenzidine on the conversion of cholesterol to pregnenolone was investigated using a reconstituted enzyme system comprised of adrenodoxin, adrenodoxin reductase and cytochrome P-450scc purified from bovine adrenal cortex. Under conditions where the cytochrome P-450scc concentration was rate-limiting, 3-methoxybenzidine was found to be a potent inhibitor, causing 50% inhibition at 7 muM when using a cholesterol concentration of 70 muM. The parent compound, benzidine, was much less effective, exhibiting an Icn value of approximately 40 muM. No effect of 3-methoxybenzidine was observed on the adrenodoxin reductase and adrenodoxin-catalyzed reduction of cytochrome c by NADPH, and it is concluded that 3-methoxybenzidine acts on cytochrome P-450scc in inhibiting cholesterol side chain cleavage.

A series of cyclic imides and related compounds have previously been shown to possess hypolipidemic activity at the low dose level of 20 mg/kg/d. Hydrolytic and reduced products of the cyclic imides were synthesized and examined to discern if possible metabolic products were the active chemical species of these hypolipidemic agents. Phthalimide proved to be the most active cyclic imide tested. Unfortunately, the new products did not, in general, improve hypolipidemic activity in rodents. The exceptions were piperidine which demonstrated improved hypotriglyceridemic activity, and 3,4,5,6-dibenzohomopiperidin-2-one, which demonstrated improved hypocholesterolemic activity compared to phthalimide.
