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.

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.

Chen, Tiffany Q. published the artcileUnified Approach to Decarboxylative Halogenation of (Hetero)aryl Carboxylic Acids, Application In Synthesis of 6313-54-8, the publication is Journal of the American Chemical Society (2022), 144(18), 8296-8305, database is CAplus and MEDLINE.

A general catalytic method for direct decarboxylative halogenation of (hetero)aryl carboxylic acids RC(O)OH (R = 4-sulfamoylphenyl, 5-methylpyridin-2-yl, isoquinolin-1-yl, etc.) via ligand-to-metal charge transfer was reported. This strategy accommodates an exceptionally broad scope of substrates. An aryl radical intermediate is leveraged toward divergent functionalization pathways: (1) atom transfer to access bromo- or iodo(hetero)arenes or (2) radical capture by copper and subsequent reductive elimination to generate chloro- or fluoro(hetero)arenes. The proposed ligand-to-metal charge transfer mechanism is supported through an array of spectroscopic studies.

A series of enmein-type derivatives were synthesized and assayed for their antimycobacterial effects. The structures of the synthesized compounds were established by ¹H NMR, ¹³C NMR and mass spectral anal. All the compounds were screened for their antimycobacterial properties against Mycobacterium phlei, Mycobacterium smegmatis and Mycobacterium marinum. Compounds 2, 6g and 6i were found to exhibit potent antimycobacterial activity against M. phlei at a concentration of 0.5 μg/mL, which was comparable to that of pos. drug streptomycin. Furthermore, five compounds were tested against Mycobacterium tuberculosis H₃₇Rv based on the promising preliminary screening results. Among them, compound 10 showed potent activity with IC₅₀ value of 17.1 μg/mL against M. tuberculosis H₃₇Rv strain. Thus, compound 10 could emerge as a promising lead for further research work.
