The saturated vapor pressures of 4-fluorophthalic anhydride and 4-chlorophthalic anhydride at various temperatures ranging from T = (426 to 560) K, and the isobaric vapor-liquid phase equilibrium data for binary system of 4-fluorophthalic anhydride (1) + 4-chlorophthalic anhydride (2) at pressures of 21.33 kPa, 41.33 kPa, 61.33 kPa and 81.33 kPa were measured exptl. by means of an inclined ebulliometer. The relationship between saturated vapor pressure and temperature was fitted by using two Antoine equations and the Antoine constants were acquired for 4-fluorophthalic anhydride and 4-chlorophthalic anhydride, resp. The semi-empirical method, Herington method was employed to test thermodn. consistency of the vapor-liquid equilibrium data. The isobaric vapor-liquid phase equilibrium data were fitted with three thermodn. models, which corresponded to Wilson, NRTL and UNIQUAC. The parameters of the three activity coefficient models were obtained by the method of nonlinear least-square regression. The calculated vapor-liquid phase equilibrium data with the three activity coefficient models agree very well with the exptl. values.

10-Me-Aplog-1 as a simplified analog of tumor-promoting debromoaplysiatoxin and a potent activator of protein kinase C (PKC) is a promising chemotherapeutic agent. In this study, we synthesized a des-A-ring analog of 18-deoxy-aplog-1 as a synthetically-accessible analog. Compound 4 retained the conformation of the PKC-recognition part of aplogs. Moderate affinity for conventional PKC isoenzymes (α, β, γ) and anti-proliferative activity against NCI-H460 (lung) and MKN45 (stomach) human cancer cell lines were observed The results suggest that 4 could serve as a lead compound for the development of conventional PKC isoenzyme-selective chemotherapeutic agents.

Li, Qingrui; Yin, Yunnian; Li, Yabo; Zhang, Jianye; Huang, Mengmeng; Kim, Jung Keun; Wu, Yangjie published the artcile< A simple approach to indeno-coumarins via visible-light-induced cyclization of aryl alkynoates with diethyl bromomalonate>, Product Details of C9H5ClO2, the main research area is indenochromene preparation regioselective; aryl alkynoate diethyl bromomalonate cyclization reaction photocatalyst.

Visible-light-induced triple-domino cyclization between aryl alkynoates R1C6H4OC(O)CCC6H4R2 (R1 = H, 2-Cl, 3-tert-Bu, etc.; R2 = H, 4-Me, 4-Cl, 4-F, 4-OMe) and di-Et bromomalonate was developed for the synthesis of indeno-coumarins I (R3 = H, 1-Cl, 4-tert-Bu, 2-tert-Bu, etc.; R4 = H, 9-Me, 9-F, 9-Cl, 9-MeO). This one-pot method substantially simplified the production process for indeno-coumarins I and a series of indeno-coumarins could be isolated in moderate to high yields. It was found that the obtained indeno-coumarins I could be used as addnl. photosensitizers to initiate this transformation. A possible radical mechanism accompanying the processes of electron transfer and energy transfer is proposed based on the results of ESI-MS anal., cyclic voltammetry, Stern-Volmer quenching experiments and control experiments The photoluminescence properties (emission spectra and quantum yields) of the obtained indeno-coumarins I were investigated.

Zheng, Qinheng; Woehl, Jordan L.; Kitamura, Seiya; Santos-Martins, Diogo; Smedley, Christopher J.; Li, Gencheng; Forli, Stefano; Moses, John E.; Wolan, Dennis W.; Sharpless, K. Barry published the artcile< SuFEx-enabled, agnostic discovery of covalent inhibitors of human neutrophil elastase>, Formula: C4H4ClNO2, the main research area is SuFEx agnostic covalent neutrophil elastase inhibitor crystal structure; SuFEx; agnostic; click chemistry; covalent inhibitor; elastase.

Sulfur fluoride exchange (SuFEx) has emerged as the new generation of click chem. We report here a SuFEx-enabled, agnostic approach for the discovery and optimization of covalent inhibitors of human neutrophil elastase (hNE). Evaluation of our ever-growing collection of SuFExable compounds toward various biol. assays unexpectedly revealed a selective and covalent hNE inhibitor: benzene-1,2-disulfonyl fluoride. Synthetic derivatization of the initial hit led to a more potent agent, 2-(fluorosulfonyl)phenyl fluorosulfate with IC50 0.24μM and greater than 833-fold selectivity over the homologous neutrophil serine protease, cathepsin G. The optimized, yet simple benzenoid probe only modified active hNE and not its denatured form.

Simpson, Harold N.; Hancock, C. Kinney; Meyers, Edward A. published the artcile< The correlation of the electronic spectra, acidities, and polarographic oxidation half-wave potentials of 4-substituted 2-chlorophenols with substituent constants>, Related Products of 3964-57-6, the main research area is .

The electronic spectra, pKA values, and polarographic oxidation half-wave potentials of a series of 4-substituted 2-chlorophenols (I) have been measured. Correlations of these data have been made and compared with correlations previously reported for a series of 4-substituted 2-nitrophenols (II) and a series of 5-substituted 2-nitrophenols (III). For all three of these series, there are excellent correlations between pKA and σ, with the ρ value of -2.22 for I agreeing closely with that of -2.16 for II but being much more positive than that of -3.01 for III. As with II and III, there is a good correlation between νB and νA, but the relationship between Δν and pKA is unsatisfactory. Excellent correlations exist between E1/2 and σ and between E1/2 and pKA. These and other relationships are discussed.

M.; Shrestha, Ruja; Weix, Daniel J. published the artcile< Nickel-Catalyzed Reductive Conjugate Addition of Primary Alkyl Bromides to Enones To Form Silyl Enol Ethers>, Computed Properties of 16799-05-6, the main research area is reductive conjugate addition primary alkyl bromide enone nickel catalyst; silyl enol ether preparation.

Conjugate addition of organometallic reagents to enones to form silyl enol ether products is a versatile method to difunctionalize activated olefins, but the organometallic reagents required can be limiting. The reductive cross-electrophile coupling of unhindered primary alkyl bromides with enones and chlorosilanes to form silyl enol ether products is catalyzed by a nickel-complexed ortho-brominated terpyridine ligand. The conditions are compatible with a variety of cyclic/acyclic enones and functional groups.

Sakura, Mizuaki; Masuda, Hitoshi; Matsukoa, Yoh; Yokoyama, Minato; Kawakmi, Satoru; Kihara, Kazunori published the artcile< Rolipram, a specific type-4 phosphodiesterase inhibitor, inhibits cyclophosphamide-induced haemorrhagic cystitis in rats>, Application In Synthesis of 6055-19-2, the main research area is rolipram phosphodiesterase inhibitor cyclophosphamide monohydrate hemorrhagic cystitis iNOS antiinflammatory.

To investigate the protective roles of type 4 phosphodiesterase (PDE4) inhibitor in cyclophosphamide (CYP)-induced hemorrhagic cystitis, as the PDE4 inhibitor has anti-inflammatory effects but its characterization is still unknown in urinary tract diseases. In female Sprague-Dawley rats, CYP was administered i.p. and bladders were harvested 24 h after CYP injection. In another group, rolipram as a PDE4 inhibitor was administered before CYP treatment. The effects and mechanisms of CYP with/ without rolipram pretreatment were evaluated by microscopic features, bladder wet weight, myeloperoxidase (MPO) activity, nitric oxide (NO)-metabolite production and expression levels of inflammation-related genes. CYP injection resulted in severe cystitis. Pretreatment with rolipram significantly reduced the increase in bladder wet weight and MPO activity, and ameliorated histol. inflammatory changes caused by CYP. The levels of inflammation-related transcripts including inducible NO synthase (iNOS), interleukin-1β and tumor necrosis factor-α, induced by CYP, were down-regulated significantly by pretreatment with rolipram. Also, rolipram reduced the NO-metabolite production and iNOS protein expression in the immunohistochem. examination These results indicate that rolipram can attenuate the development of CYP-induced cystitis in rats by suppressing cytokine production and iNOS induction. Thus, treatment with PDE4 inhibitor has potential clin. implications of the prevention of bladder inflammatory diseases.
