Millet, Antoine published the artcileDiscovery and Optimization of N-(4-(3-Aminophenyl)thiazol-2-yl)acetamide as a Novel Scaffold Active against Sensitive and Resistant Cancer Cells, COA of Formula: C9H5ClO4S, the publication is Journal of Medicinal Chemistry (2016), 59(18), 8276-8292, database is CAplus and MEDLINE.

Cancer is the second cause of deaths worldwide and is forecast to affect more that 22 million people in 2020. Despite dramatic improvement in its care over the last two decades, the treatment of resistant forms of cancer is still an unmet challenge. Thus, innovative and efficient treatments are still needed. In this context, the authors report herein the synthesis and evaluation of a new class of bioactive mols. belonging to the N-(4-(3-aminophenyl)thiazol-2-yl)acetamide family. Structure-activity relationships could be driven and resulted in the discovery of lead compound I.. The latter display high in vitro potency against both sensitive and resistant cancer cell lines on three models: melanoma, pancreatic cancer, and chronic myeloid leukemia (CML). I leads to cell death by concomitant induction of apoptosis and autophagy, shows good pharmacokinetic properties, and demonstrates a significant reduction of tumor growth in vivo on A375 xenograft model in mice.

Lin, Xi published the artcileEffects of dietary anaplerotic and ketogenic energy sources on renal fatty acid oxidation induced by clofibrate in suckling neonatal pigs, Computed Properties of 637-07-0, the publication is International Journal of Molecular Sciences (2020), 21(3), 726, database is CAplus and MEDLINE.

Maintaining an active fatty acid metabolism is important for renal growth, development, and health. We evaluated the effects of anaplerotic and ketogenic energy sources on fatty acid oxidation during stimulation with clofibrate, a pharmacol. peroxisome proliferator-activated receptor α (PPARα) agonist. Suckling newborn pigs (n = 72) were assigned into 8 dietary treatments following a 2 x 4 factorial design: ± clofibrate (0.35%) and diets containing 5% of either (1) glycerol-succinate (GlySuc), (2) tri-valerate (TriC5), (3) tri-hexanoate (TriC6), or (4) tri-2-methylpentanoate (Tri2MPA). Pigs were housed individually and fed the iso-caloric milk replacer diets for 5 d. Renal fatty acid oxidation was measured in vitro in fresh tissue homogenates using [1-14C]-labeled palmitic acid. The oxidation was 30% greater in pig received clofibrate and 25% greater (p < 0.05) in pigs fed the TriC6 diet compared to those fed diets with GlySuc, TriC5, and Tri2MPA. Addition of carnitine also stimulated the oxidation by twofold (p < 0.05). The effects of TriC6 and carnitine on palmitic acid oxidation were not altered by clofibrate stimulation. However, renal fatty acid composition was altered by clofibrate and Tri2MPA. In conclusion, modification of anaplerosis or ketogenesis via dietary substrates had no influence on in vitro renal palmitic acid oxidation induced by PPARα activation.

Esteva-Font, Cristina published the artcileStructure-activity analysis of thiourea analogs as inhibitors of UT-A and UT-B urea transporters, Recommanded Product: 1-(4-Chlorophenyl)thiourea, the publication is Biochimica et Biophysica Acta, Biomembranes (2015), 1848(5), 1075-1080, database is CAplus and MEDLINE.

Small-mol. inhibitors of urea transporter (UT) proteins in kidney have potential application as novel salt-sparing diuretics. The urea analog dimethylthiourea (DMTU) was recently found to inhibit the UT isoforms UT-A1 (expressed in kidney tubule epithelium) and UT-B (expressed in kidney vasa recta endothelium) with IC₅₀ of 2-3 mM, and was shown to have diuretic action when administered to rats. Here, we measured UT-A1 and UT-B inhibition activity of 36 thiourea analogs, with the goal of identifying more potent and isoform-selective inhibitors, and establishing structure-activity relationships. The analog set systematically explored modifications of substituents on the thiourea including alkyl, heterocycles and Ph rings, with different steric and electronic features. The analogs had a wide range of inhibition activities and selectivities. The most potent inhibitor, 3-nitrophenyl-thiourea, had an IC₅₀ of ∼ 0.2 mM for inhibition of both UT-A1 and UT-B. Some analogs such as 4-nitrophenyl-thiourea were relatively UT-A1 selective (IC₅₀ 1.3 vs. 10 mM), and others such as thioisonicotinamide were UT-B selective (IC₅₀ > 15 vs. 2.8 mM).

Gottardi, Waldemar published the artcileThe Integral Method, a new approach to quantify bactericidal activity, Application In Synthesis of 7080-50-4, the publication is Journal of Microbiological Methods (2015), 71-78, database is CAplus and MEDLINE.

The bactericidal activity (BA) of antimicrobial agents is generally derived from the results of killing assays. A reliable quant. characterization and particularly a comparison of these substances, however, are impossible with this information. We here propose a new method that takes into account the course of the complete killing curve for assaying BA and that allows a clear-cut quant. comparison of antimicrobial agents with only one number The new Integral Method, based on the reciprocal area below the killing curve, reliably calculates an average BA [log₁₀ CFU/min] and, by implementation of the agent’s concentration C, the average specific bactericidal activity SBA = BA / C [log₁₀ CFU/min/mM]. Based on exptl. killing data, the pertaining BA and SBA values of exemplary active halogen compounds were established, allowing quant. assertions. N-chlorotaurine (NCT), chloramine T (CAT), monochloramine (NH₂Cl), and iodine (I₂) showed extremely diverging SBA values of 0.0020 ± 0.0005, 1.11 ± 0.15, 3.49 ± 0.22, and 291 ± 137 log₁₀ CFU/min/mM, resp., against Staphylococcus aureus. This immediately demonstrates an approx. 550-fold stronger activity of CAT, 1730-fold of NH₂Cl, and 150,000-fold of I₂ compared to NCT. The inferred quant. assertions and conclusions prove the new method suitable for characterizing bactericidal activity. Its application comprises the effect of defined agents on various bacteria, the consequence of temperature shifts, the influence of varying drug structure, dose-effect relationships, ranking of isosteric agents, comparison of competing com. antimicrobial formulations, and the effect of additives.

Wondraczek, Holger published the artcileWater soluble photoactive cellulose derivatives: synthesis and characterization of mixed 2-[(4-methyl-2-oxo-2H-chromen-7-yl)oxy]acetic acid-(3-carboxypropyl)trimethylammonium chloride esters of cellulose, COA of Formula: C7H16ClNO2, the publication is Cellulose (Dordrecht, Netherlands) (2012), 19(4), 1327-1335, database is CAplus.

Photoactive derivatives of cellulose were prepared by a mild esterification of the biopolymer with 2-[(4-methyl-2-oxo-2H-chromen-7-yl)oxy]acetic acid via the activation of the carboxylic acid with N,N’-carbonyldiimidazole. Subsequently, modification with the cationic carboxylic acid (3-carboxypropyl)trimethylammonium chloride was carried out. Thus, water soluble polyelectrolytes decorated with high amounts of photochem. active chromene moieties were obtained. The structures of the novel polysaccharide esters and the polyelectrolytes were evaluated by means of NMR and IR spectroscopy. Moreover, the light triggered photodimerization of the chromene moieties of the photoactive polyelectrolytes was studied by means of UV-Vis spectroscopy in the dissolved state. The photochem. observed may be used to control the properties of the new polysaccharide derivatives and are thus of interest in the design of smart materials.

Vega, B. published the artcileStudies on the fibre surfaces modified with xylan polyelectrolytes, HPLC of Formula: 6249-56-5, the publication is Carbohydrate Polymers (2012), 89(3), 768-776, database is CAplus and MEDLINE.

Xylan was isolated from birch wood chips by using pressurized hot water extraction (PHWE). The extracted xylan was chem. modified yielding three different xylan derivatives (XDs): xylan sulfate (XS), carboxymethyl xylan (CMX) and xylan-4-[N,N,N-trimethylammonium]butyrate chloride (XTMAB). The structure and mol. weight of XDs was determined by using NMR spectroscopy and size exclusion chromatog. (SEC). The potential utilization of xylan polyelectrolytes for modifying fiber surfaces was assessed by sorption experiments using bleached pine Kraft pulp as substrate. Polyelectrolyte titration method was chosen for estimating the amount of sorbed XDs onto the fibers. The cationic xylan derivative XTMAB had a strong interaction with fibers while the anionic derivatives did not show any sorption. XPS and time of flight secondary ion mass spectrometry (ToF-SIMS) were selected as advanced surface analyses for studying the amount of surface anionic groups and the surface distribution of the XTMAB. XPS and polyelectrolyte titration results suggested that the XTMAB is sorbed onto the fiber surfaces. ToF-SIMS imaging showed that XTMAB was evenly distributed on fiber surfaces.
