Furazadrol ([1′,2′]isoxazolo[4′,5′:2,3]-5alpha-androstan-17beta-ol) is a designer anabolic androgenic steroid that is readily available via the internet. It contains an isoxazole fused to the steroid A-ring which offers metabolic stability and noteworthy anabolic activity raising concerns over the potential for abuse of this compound in equine sports. The metabolism of furazadrol was studied by in vivo and in vitro methods for the first time. Urinary furazadrol 17-sulfate and furazadrol 17-glucuronide metabolites were detected in vivo after a controlled administration and compared with synthetically-derived reference materials in order to confirm their identities. They were quantified to establish the excretion profile and a suitable limit of detection. Minor metabolites were also detected, including epifurazadrol, hydroxylated furazadrol, and hydroxylated and oxidised furazadrol, present as the sulfate and glucuronide conjugates. Phase II metabolites were subjected to enzymatic hydrolysis by Escherichia coli beta-glucuronidase and Pseudomonas aeruginosa arylsulfatase to further confirm the identity of the corresponding phase I metabolites. The metabolism profile was compared to the products obtained from an in vitro phase I metabolism study, with all but two of the minor in vivo phase I metabolites observed in the in vitro system. These investigations identify the key urinary metabolites of furazadrol following oral administration, which can be incorporated into anti-doping screening and confirmation procedures.

BACKGROUND: Herbicides that inhibit 4-hydroxyphenylpyruvate dioxygenase (HPPD, EC 1.13.11.27) are very important for grass weed control. In order to discover novel HPPD herbicides, a series of triketone 2H-benzo[b] oxazin-3(4H)-one analogs was designed and synthesized. RESULTS: In comparison with the commercial triketone HPPD herbicide mesotrione (IC50 = 0.252 muM), some of these new triketone analogs displayed excellent HPPD inhibitory potency in vitro, for example B39 (IC50 = 0.172 muM) and B41 (IC50 = 0.156 muM). In addition, some of these compounds exhibited pre- and post-emergence herbicidal activity similar to mesotrione when applied at 375 g/ha. CONCLUSION: Many of the title compounds described in this paper could be important lead structures for the further development of novel HPPD herbicides.

Conversion of lignin to aromatic compounds via C-C/C-O bond cleavage has been an attractive but challenging subject in recent years. We herein report the first protocol that converts lignin models and preoxidized lignin to isoxazole and aromatic nitrile. The isoxazole motif is constructed by condensation of beta-hydroxyl ketone with hydroxylamine. Magnesium oxide promotes an oximation reaction and an intramolecular condensation. Aromatic nitriles and esters are obtained via Beckmann rearrangement or an acidolysis reaction depending on the selected additive. The hydroxylamine-mediated strategy works well for the preoxidized lignin conversion to aromatic isoxazole, nitrile, and ester monomers with up to 7.6% yield.

In the present work, the combined electronic structure calculations and surface hopping simulations have been performed to investigate the excited-state decay of the parent oxazole in the gas phase. Our calculations show that the S2 state decay of oxazole is an ultrafast process characterized by the ring-opening and ring-closure of the five-membered oxazole ring, in which the triplet contribution is minor. The ring-opening involves the O-C bond cleavage affording the nitrile ylide and airine intermediates, while the ring-closure gives rise to a bicyclic species through a 2-5 bond formation. The azirine and bicyclic intermediates in the S0 state are very likely involved in the phototranspositions of oxazoles. This is different from the previous mechanism in which these intermediates in the T1 state have been proposed for these phototranspositions.

To determine the preferred water molecule binding sites of the polybasic sulfa drugs sulfamethoxazole (SMX) and sulfisoxazole (SIX), we have studied their monomers and monohydrated complexes through laser-desorption conformer-specific UV and IR spectroscopy. Both the SMX and SIX monomer adopt a single conformer in the molecular beam. On the basis of their conformer-specific IR spectra in the NH stretch region, these conformers were assigned to the SMX and SIX global minimum structures, both exhibiting a staggered sulfonamide group and an intramolecular C-H?OS hydrogen bond. The SMX-H2O and SIX-H2O complexes each adopt a single isomer in the molecular beam. Their isomeric structures were determined based on their isomer-specific IR spectra in the NH/OH stretch region. Quantum Theory of Atoms in Molecules analysis of the calculated electron densities revealed that in the SMX-H2O complex the water molecule donates an O-H?N hydrogen bond to the heterocycle nitrogen atom and accepts an N-H?O hydrogen bond from the sulfonamide NH group. In the SIX-H2O complex, however, the water molecule does not bind to the heterocycle but instead donates an O-H?OS hydrogen bond to the sulfonamide group and accepts an N-H?O hydrogen bond from the sulfonamide NH group. Both water complexes are additionally stabilized by a Cph-H?OH2 hydrogen bond. Interacting Quantum Atoms analysis suggests that all intermolecular hydrogen bonds are dominated by the short-range exchange-correlation contribution.

Four complexes of Co(II), Ni(II), Cu(II), and Zn(II) with isoxicam (H2ISO) as ligand, namely [Co(HISO)2(H2O)2]?3H2O (Co?Iso), [Ni(HISO)2(H2O)2]?0.5H2O (Ni?Iso), [Cu(HISO)2(H2O)] (Cu?Iso), [Zn(HISO)2(H2O)2]?0.5H2O (Zn?Iso), have been synthesized and characterized by FT-IR, UV?Vis?NIR, 1H NMR, TG/DSC, elemental analysis, magnetic and conductivity measurements. The following permanent cell lines were used to evaluate the cytotoxic activity of the compounds: LSCC-SF-Mc29, strain E7 (transplantable chicken hepatoma induced by the myelocytomatosis virus Mc29), LSR-SF-SR (transplantable sarcoma in rat, induced by Rous sarcoma virus, strain Schmidt-Ruppin), MCF-7 (luminal A type breast cancer), HeLa (human carcinoma of the uterine cervix) and Lep-3 (human non-tumor embryonal fibroblastoid cells). Short term experiments (24?72 h) with monolayer cultures were performed by MTT test, neutral red uptake cytotoxicity assay and double staining with acridine orange and propidium iodide as well as long term experiments (20 days) with 3D cancer cell colonies in semi-solid medium. The results obtained reveal that: (i) applied at a concentration range of 5?500 mug mL?1 the compounds investigated decrease in a time- and concentration-dependent manner viability and/or proliferation of the treated cells; (ii) metal complexes are more pronounced cytotoxic agents as compared to isoxicam; (iii) cell-specific response was observed?Cu?Iso expresses the highest cytotoxic activity in LSCC-SF-Mc29 (strain E7) cells, whereas Zn?Iso is the most effective compound in LSR-SF-SR and Lep-3 cells, and Co?Iso?in HeLa cells; (iv) in general, human non-tumor Lep-3 embryonic fibroblastoid cells are relatively less sensitive to the cytotoxic activity of the complexes as compared to human cancer MCF-7 and HeLa cells.

Isoprenoids are a diverse family of compounds derived from the five-carbon precursors isopentenyl diphosphate (IPP) and dimethylallyl diphosphate (DMAPP). Present in all domains of life, isoprenoids are essential for cell survival and participate in a variety of biological functions. Given that isoprenoids play a critical role in bacterial physiology and are utilized for cell wall biogenesis, membrane stability, protein synthesis, respiratory energy generation, and virulence, isoprenoid biosynthesis has been considered an attractive target for antibacterial drug discovery. Bacteria use one of two non-homologous pathways to produce IPP and DMAPP, the mevalonate pathway and the methylerythritol 4-phosphate pathway. As such, there are a multitude of essential enzymes that represent promising drug targets. Herein, the biochemical and cellular activities of antibacterial leads targeting isoprenoid biosynthesis are discussed.

Introduction: The bromodomain-containing protein 4 (BRD4), a member of the bromodomain and extra-terminal (BET) family, functions as an ?epigenetic reader? that binds to acetylated lysine (KAc) residues on histone tails sophisticatedly regulating chromatin structure and gene expression. Recently, emerging evidence demonstrates that BRD4 plays a significant role in the occurrence and progression of several malignant human diseases especially cancers, making it a hot target in cancer therapy. Areas covered: This review mainly summarizes the patents of BRD4 inhibitors that have been authorized from 2013 to 2019. The patents are mostly described in terms of chemical structures, molecular mechanisms of action, pharmacological activities and potential clinical applications, including combination therapies. The development of BRD4 inhibitors in the clinical phase has been highlighted. Prospects for further development of more selective BRD4 inhibitors are provided. Expert opinion: In 2013?2019, several previously known chemical scaffolds have been further developed and disclosed. Although many small molecule BRD4 inhibitors with high potency and diverse scaffolds have been developed, the selectivity of most BRD4 inhibitors still needs to be improved. Therefore, the development of more selective small molecule inhibitors or combined use of drugs such as immunotherapy may provide new ideas for drug development.
