Here in, the effects of FeSiAl particle size on the dielectric and microwave absorption properties of FeSiAl/Al2O3 composites were studied. FeSiAl/Al2O3 composites containing 18-25 mu m, 25-48 mu m, and 48-75 mu m FeSiAl particles were prepared by hot-pressed sintering based on uniformly mixed FeSiAl and Al2O3 powders. Results show that the real permittivity and the imaginary permittivity are significantly promoted with increasing FeSiAl particle size, which is ascribed to the enhanced interfacial polarization and conductance loss. In addition, the favorable matching impedance and suitable attenuation coefficient enabled the composite containing 25-48 mu m FeSiAl powder to show a minimum reflection loss of -34.4 dB at 11.7 GHz and an effective absorption bandwidth (<-10 dB) of 1.4 GHz in 11.0-12.4 GHz, when the thickness is 1.1 mm. By adjusting the thickness to 1.4 mm, the effective absorption bandwidth of the composite reaches a maximum value of 2.0 GHz in the 8.3-10.3 GHz range, indicating tunable, strong, and highly efficient microwave absorption performance.

Aerobic organisms must rely on abundant intracellular thiols to reductively protect various vital functional units, especially ubiquitous zinc(II) thiolate sites of proteins, from deleterious oxidations resulting from oxidizing environments. Disclosed here is the first well-defined model study for reactions between zinc(II) thiolate complexes and copper(II) complexes. Among all the studied ligands of copper(II), diethyldithiocarbamate (DTC) displays a unique redox-tuning ability that enables copper(II) to resist the reduction by thiols while retaining its ability to oxidize zinc(II) thiolates to form disulfides. This work proves for the first time that it is possible to develop oxidants to discriminate between thiols and zinc(II) thiolates, alluding to a new chemical principle for how oxidants, especially universal anticancer Cu(DTC)(2), might circumvent the intracellular reductive defense around certain zinc(II) thiolate sites of proteins to kill malignant cells.

The Pd(ii)-catalyzed activation of Csp(2)-H bond and double alkyne annulation which proceeds via allylic isomerization is reported for the first time. This reaction of antipyrines with alkynes provides an efficient synthetic route for the biologically important spiro-cyclopentadiene pyrazolones. In the presence of Lawesson’s reagent, this Pd(ii)-catalyzed annulation reaction affords another spiro-cyclopentadiene pyrazolone which displays very good fluorescence properties.

Deregulation of the transcriptional repressor BCL6 enables tumorigenesis of germinal center B-cells, and hence BCL6 has been proposed as a therapeutic target for the treatment of diffuse large B-cell lymphoma (DLBCL). Herein we report the discovery of a series of benzimidazolone inhibitors of the protein-protein interaction between BCL6 and its co-repressors. A subset of these inhibitors were found to cause rapid degradation of BCL6, and optimization of pharmacokinetic properties led to the discovery of 5-((5-chloro-2-((3R,SS)-4,4-difluoro-3,5-dimethylpiperi din-1-yl) pyrimidin-4-yl) amino)-3-(3-hydroxy-3-methylbutyl)-1-methyl-1,3-dihydro-2H-benzo[d]imidazol-2-one (CCT369260), which reduces BCL6 levels in a lymphoma xenograft mouse model following oral dosing.

Background: Transrectal ultrasound-guided prostate biopsy (TRBx) or transperineal Bx (TPBx) are considered alternative approaches for the diagnosis of prostate cancer (PCa). However, urinary tract infection (UTI) or other complications could be more frequent in the TRBx approach. Objective: To determine the complication rate following different antimicrobial prophylaxis (AMP; fosfomycin trometamol [FT] vs beta-lactame or fluorochinolones [FQ]) in patients undergoing TRBx or TPBx. Design, setting, and participants: The analyses were based on prospectivelycollected data of a cohort of patients who underwent TRBx or TPBx for elevated prostate-specific antigen (PSA; >= 4 ng/ml) or clinical suspicion of PCa, between September 2016 and March 2017. Patients received a single dose of 3 g oral FT (group A) or, alternatively, FQ or beta-lactame (group B). Intervention:TRBx versus TPBx. Outcome measurements and statistical analysis: Adjustment variables consisted of age, PSA, biopsy technique (TPBx vs TRBx), and antibiotic prophylaxis (FT vs beta-lactame or FQ) using 1:1 propensity-score matching. Overall, 526 patients were considered, of whom 258 received FT (group A) and the other 258 received beta-lactame or FQ (group B). Results and limitations: Overall complications occurred in 390 (75.58%) and major complications in 67/516 (12.98%). Lower prevalence of UTIs was detected in group A (34.1%) compared with that in group B (43.4%; p = 0.03), while similar rates of haematuria (54.7% vs 55.4%), haemospermia (39.5% vs 33.0%), and acute urinary retention (11.6% vs 9.3%) were detected in groups A and B. We found that group B (odds ratio [OR]: 1.54; p = 0.03), I grade haematuria (OR: 6.17; p < 0.01), and II grade haematuria (OR: 5.13; p < 0.01) were significantly associated with increased risk of UTIs. Conclusions: AMP with fluoroquinoles or beta-lactam antibiotics increased the rate of UTIs, when compared with FT, in patients undergoing TRBx or TPBx. The appearance of haematuria or haemospermia is associated with UTIs, suggesting the possibility of tailoring the strategy for prophylaxis in this category of patients. Patient summary: In this study, comparing complications after transrectal ultrasound-guided prostate biopsy versus transperineal biopsy, prophylaxis with fluoroquinoles or beta-lactam antibiotics increased the rate of urinary tract infections when compared with fosfomycin trometamol, regardless of the type of biopsy approach.

A catalyst system comprising of pyrazolylpyridineamine/Cu(I)/CsOH is reported. for the hydroxylation of aryl iodides and bromides with moderate to outstanding yields, without the use of an inert atmosphere. A comprehensive parameter optimisation study established optimum component concentrations: [Cu(MeCN)(4)]BF4 and 2-(1H-pyrazol-1-yl)-N-(pyridine-2-ylmethyl)ethan-1-amine (L01) (2 mol %), substrate (1 mmol), CsOH (4 mmol) and DMSO:H2O (1:1, 3 mL). Monitoring substrate conversion as a function of time revealed an induction period of 90 min, which could be eliminated through the initial in situ formation of the proposed [(L01)Cu-OH] intermediate. Eliminating the induction period resulted in complete conversion within one hour, with turnover numbers exceeding that of the benchmark catalyst system operating at an optimal catalyst loading of 0.05 mol %.

The controlled generation of hydrogen sulfide (H2S) under biologically relevant conditions is of paramount importance due to therapeutic interests. Via exploring the reactivity of a structurally characterized phenolate-bridged dinuclear zinc(II)-aqua complex {LZnII(OH2)}(2)(ClO4)(2) (1a) as a hydrolase model, we illustrate in this report that complex 1a readily hydrolyses CS2 in the presence of Et3N to afford H2S. In contrast, penta-coordinated [Zn-II] sites in dinuclear {(LZnII)(2)(mu-X)}(ClO4) complexes (7, X = OAc; 8, X = dimethylpyrazolyl) do not mediate CS2 hydrolysis in the presence of externally added water and Et3N presumably due to the unavailability of a coordination site for water at the [Zn-II] centers. Moreover, [Zn-II]-OH sites present in the isolated tetranuclear zinc(II) complex {(LZnII)(2)(mu-OH)}(2)(ClO4)(2) (4) react with CS2, thereby suggesting that the [Zn-II]-OH site serves as the active nucleophile. Furthermore, mass spectrometric analyses on the reaction mixture consisting of 1a/Et3N and CS2 suggest the involvement of zinc(II)-thiocarbonate (3a) and COS species, thereby providing mechanistic insights into CS2 hydrolysis mediated by the dinuclear [Zn-II] hydrolase model complex 1a.

The present study pertains to the synthesis and characterizations of nine novel mixed-ligand complexes of [Zn(Hdmpz)(2)(L1)(2)] (1) (dmpz = 3,5-dimethylpyrazolate, Ll = 2-bromobenzoate), [Zn(Hdmpz)(2)(L2)(2)] (2) (L2 = 4-tert-butylbenzoate), Zn(Hdmpz)(2)(L3)(2) (3) (L3 = 2-thiophenoate), [Zn(Hdmpz)(2)(L4)(2)] (4) (L4 = 4-methylsalicylate), [Cd(Hdmpz)(2)(L5)(2)](2) (5) (L5 = 2,6-dihydroxy benzoate), [Cd (Hdmpz)(2)(L6)(2)](2).2H(2)O (6) (L6 = 3-(4-methoxy-phenylcarbamoyI)-acrylate), [Zn(Hdmpz)(2)(L7)](2) (7) (L7 = acetylenedicarboxylate), [Zn(Hdmpz)(2)(L8)] (8) (L8 = 1,2-phenylenediacetate), and [Cd(Hdmpz)(L9) (H2O)(2)].H2O (9) (L9 = 3-nitrophthalate). The resulting complexes were formulated via EA, IR, and SCXRD, and the TGA of all the complexes was also evaluated. The X-ray studies reveal that these complexes present mononuclear to dinuclear structures with tetrahedral geometry around each Zn2+, and octahedral/pentagonal bipyramidal geometry for Cd2+ The Hdmpzs in all compounds are coordinated only in monodentate fashion with its neutral N. The carboxylates at 1-4 and 3-9 function only as unidentate coordination units, the CO2- in 5 has the chelating bidentate coordination mode. Compound 6 contains both unidentate bridging and bidentate chelating COO-. The free carboxylate 0 at 2-4 and 7-8 accept the intramolecular N-H…O H-bonds, at 1 and 7 the uncoordinated O participate in the intermolecular N-H…O H-bonds. For 6 there is intermolecular N H-0 H-bond from the NHCO and H2O, and intramolecular N-H…O H-bonds from the NH at Hdmpz, the NHCO (acceptor), and one 0 at the bismonodentate coordinated COO-. One anion at 6 also gives the intramolecular N H-H-bonds from the NHCO(donor) and one O at the bismonodentate coordinated COO-. The intermolecular N-H…O H-bonds are from the phenol at both 4 and 5, and from the H2O at 9. The CH3 at Hdmpz in all compounds are participated in the noncovalent bonds except 3. The intricate intra-and intermolecular N-H…O and O-H…O H-bonds as well as C-H…N, C-H, O..O, Br…O, CH3…CH, CH2…C, CH3…C, C-H..O, CH2…O, CH3…O, C-H…S, C-H…CH3- rt, and pi…phi associations are elucidated by the X-ray crystallographic studies, which unite the discrete units into high-dimensional ordered supramolecular structures.
