Herein we describe the synthesis of a series of new potent tachykinin NK2 receptor antagonists by the modulation of the C- and N-terminal moieties of ibodutant (MEN 15596, 1). The N-terminal benzo[b]thiophene ring was replaced by different substituted naphthalenes and benzofurans, while further modifications were evaluated at the C-terminal tetrahydropyran moiety. Most compounds demonstrated a high affinity for the human NK2 receptor and high in vitro antagonist potency, indicating that a wide range of substituents at both termini can be incorporated in the mol. without detrimental effects on the interactions with the NK2 receptor. Selected compounds were tested in vivo confirming their activity as NK2 antagonists. In particular, after both iv and id administration to guinea pig, compound 61 b was able to antagonize NK2-induced colonic contractions with a potency and duration-of-action fully comparable to the reference compound 1 (MEN 15596, ibodutant).

Kovalcik, Thomas R.; Guillory, J. Keith published the artcile< Stability of cyclophosphamide in lyophilized cakes. II. Urea, polyvinylpyrrolidone, and dextran as excipients>, COA of Formula: C7H17Cl2N2O3P, the main research area is cyclophosphamide stability lyophilization; excipient cyclophosphamide stability lyophilization.

Lyophilized products containing cyclophosphamide (I) and one of the following excipients: urea, polyvinylpyrrolidone (PVP-40), or dextran, were prepared All of the products were well-formed cakes. I in these lyophilized cakes underwent rapid (t90 < 30 days) degradation in the solid state at room temperature The lyophilized cakes were humidified with 5 μL water. In the cake containing urea, DSC and x-ray diffraction showed that I was converted from the amorphous to the monohydrate form when exposed to moisture, and exhibited improved stability. In the case of the cake containing PVP-40, the incorporation of moisture resulted in formation of a clear, semi-solid possessing poor stability. The I/dextran cake remained intact upon humidification. DSC and x-ray diffraction showed that I in this cake was not converted from the amorphous form to the monohydrate form, and exhibited no improvement in stability.

Salman, Noori Y.; Al-niami, Kisma H. Ibrahim published the artcile< Kinetic and mechanistic study of alanine oxidation by N-chlorosuccinimide using Mn2+ as catalyst>, Name: 1-Chloropyrrolidine-2,5-dione, the main research area is alanine N chlorosuccinimide manganese oxidation kinetic catalyst.

Kinetic studies of oxidation of alanine by N-chlorosuccinimide (NCIS) have been investigated at different pH’s. The reaction shows consecutive first order reaction with respect to both oxidant and substrate. Fractional order were observed in hydrogen ion and manganeseion. Slight effect of addition of reaction product (succinimide) on the rate of oxidation reaction have been noticed. Changing the ionic strength had no effect on the rate of oxidation reaction. Cl+ or NClS and NClS protonated were suggested to be the reactive species of N-chlorosuccinimide. An intermediates compounds have been found and proved by using michaelis menton equation. A reaction mechanism for the oxidation reaction was suggested.

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.

Huihui, Kierra M. 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.

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.

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.

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.
