  • A selective electrochemical sensor for caffeic acid and photocatalyst for metronidazole drug pollutant – A dual role by rod-like SrV2O6.
    Related ArticlesA selective electrochemical sensor for caffeic acid and photocatalyst for metronidazole drug pollutant - A dual role by rod-like SrV2O6. Sci Rep. 2017 08 03;7(1):7254 Authors: Karthik R, Kumar JV, Chen SM, Kumar PS, Selvam V, Muthuraj V Abstract In the present study, well-defined one-dimensional (1D) rod-like strontium vanadate (SrV2O6) was prepared by simple hydrothermal method without using any other surfactants/templates. The successful formation of rod-like SrV2O6 was confirmed by various analytical and spectroscopic techniques. Interestingly, for the first time the dual role of as-prepared rod-like SrV2O6 were employed as an electrochemical sensor for the detection of ... read more

  • Pharmacokinetic evaluation of medicinally important synthetic N,N’ diindolylmethane glucoside: Improved synthesis and metabolic stability.
    Related ArticlesPharmacokinetic evaluation of medicinally important synthetic N,N' diindolylmethane glucoside: Improved synthesis and metabolic stability. Bioorg Med Chem Lett. 2019 Feb 11;: Authors: Magotra A, Gour A, Sharma DK, Dash AK, Singh G, Mukherjee D, Nandi U Abstract An improved route for the synthesis of N,N'-diindolyl methane (DIM) glycosides has been developed by using Fe/Al pillared clay catalyst. In-silico pharmacokinetics followed by in-vitro studies like aqueous solubility, lipophilicity, P-glycoprotein (P-gp) dependent ATPase activity, permeability, plasma protein binding, RBC partitioning, metabolic stability in different liver microsomes and its in-vitro-in-vivo extrapolation were conducted for the most potent derivative namely NGD16. The compound ... read more

  • Synthesis of Cytospolide Analogues and Late-State Diversification Thereof.
    Related ArticlesSynthesis of Cytospolide Analogues and Late-State Diversification Thereof. J Org Chem. 2019 Feb 19;: Authors: Ehrlich G, Stark CBW Abstract The cytospolides are a novel group of fungal secondary metabolites first described in 2011. Although all 17 natural derivatives share the same C-14 polyketide backbone, they exhibit a fairly broad structural diversity regarding their oxygenation and acetylation pattern as well as macrolide structure, e.g. monocyclic nonanolide core or bicyclic ring systems with a bridging THF ring. In the present work, the prospects for an extension of the structural diversity of cytospolides have been investigated. Based on a previously established ... read more

  • Grob-Type Fragmentation Releases Paracyclophane Ring Strain in a Late-Stage Precursor of Haouamine A.
    Related ArticlesGrob-Type Fragmentation Releases Paracyclophane Ring Strain in a Late-Stage Precursor of Haouamine A. Org Lett. 2019 Feb 19;: Authors: Cao L, Wang C, Wipf P Abstract A ketene [2 + 2]-addition, an intramolecular aldol reaction, a Suzuki-Miyaura coupling, and a chemoselective lactam reduction were used to prepare a late-stage precursor of haouamine A. Exposure to acid led to a Grob-type fragmentation of the strained 3-aza[7]paracyclophane ring, followed by a tandem Pictet-Spengler reaction of the intermediate iminium ion and conversion to a novel 1,4a-propanocyclopenta[ b]pyridine. This cascade reaction might also be relevant for the mechanism of action of the natural ... read more

  • Molecular crypsis by pathogenic fungi using human factor H. A numerical model.
    Related ArticlesMolecular crypsis by pathogenic fungi using human factor H. A numerical model. PLoS One. 2019;14(2):e0212187 Authors: Lang SN, Germerodt S, Glock C, Skerka C, Zipfel PF, Schuster S Abstract Molecular mimicry is the formation of specific molecules by microbial pathogens to avoid recognition and attack by the immune system of the host. Several pathogenic Ascomycota and Zygomycota show such a behaviour by utilizing human complement factor H to hide in the blood stream. We call this type of mimicry molecular crypsis. Such a crypsis can reach a point where the immune system can no longer clearly distinguish between self ... read more

  • Position-Selective Synthesis and Biological Evaluation of Four Isomeric A-Ring Amino Derivatives of the Alkaloid Luotonin A.
    Position-Selective Synthesis and Biological Evaluation of Four Isomeric A-Ring Amino Derivatives of the Alkaloid Luotonin A. Molecules. 2019 Feb 16;24(4): Authors: Ibric A, Eckerstorfer S, Eder M, Louko I, Tunjic L, Heffeter P, Schueffl HH, Marian B, Haider N Abstract Following two orthogonal synthetic routes, a series of all four possible A-ring amino derivatives of the natural product Luotonin A (a known Topoisomerase I inhibitor) was synthesized. In both strategies, intramolecular cycloaddition reactions are the key step. The target compounds were obtained in good yields by mild catalytic transfer hydrogenation of the corresponding nitro precursors. In-vitro evaluation of the antiproliferative ... read more
