Ma, Yao;Bruno, Nicholas C.;Zhang, Fengyi;Finn, M. G.;Lively, Ryan P. research published 《 Zeolite-like performance for xylene isomer purification using polymer-derived carbon membranes》, the research content is summarized as follows. Polymers of intrinsic microporosity (PIMs) have been used as precursors for the fabrication of porous carbon mol. sieve (CMS) membranes. PIM-1, a prototypical PIM material, uses a fused-ring structure to increase chain rigidity between spirobisindane repeat units. These two factors inhibit effective chain packing, thus resulting in high free volume within the membrane. However, a decrease of pore size and porosity was observed after pyrolytic conversion of PIM-1 to CMS membranes, attributed to the destruction of the spirocenter, which results in the ‘flattening’ of the polymer backbone and graphite-like stacking of carbonaceous strands. Here, a spirobifluorene-based polymer of intrinsic microporosity (PIM-SBF) was synthesized and used to fabricate CMS membranes that showed significant increases in p-xylene permeability (approx. four times), with little loss in p-xylene/o-xylene selectivity (13.4 vs. 14.7) for equimolar xylene vapor separations when compared to PIM-1-derived CMS membranes. This work suggests that it is feasible to fabricate such highly microporous CMS membranes with performances that exceed current state-of-the-art zeolites at high xylene loadings.

Maertens, Gaetan;Deruer, Elsa;Denis, Maxime;Canesi, Sylvain research published 《 Common Strategy for the Synthesis of Some Strychnos Indole Alkaloids》, the research content is summarized as follows. Indole alkaloids are important natural compounds with interesting bio-activities that can be found in various species belonging to the Amaryllidaceae, Apocynaceae, or Strychnaceae families. Although these compounds have different connections, substituents, and functionalities, their main core can be produced via the formation of a common functionalized tetracyclic subunit, I, which is rapidly obtained by an oxidative de-aromatization process mediated by a hypervalent iodine reagent from an inexpensive phenol containing a lactate moiety as the chiral auxiliary. A subsequent stereoselective aza-Michael addition and an intramol. Heck-type reaction lead to the formation of a common key intermediate. This approach provides a solid foundation for the further elaborations of several natural products. The asym. syntheses of (-)-strychnopivotine and the polycyclic main cores of (-)-strychnosplendine, (+)-isosplendine, and (+)-malagashanol, three other indole alkaloids, are reported.

Mantareva, Vanya;Kussovski, Vesselin;Orozova, Petya;Angelov, Ivan;Durmus, Mahmut;Najdenski, Hristo research published 《 Palladium Phthalocyanines Varying in Substituents Position for Photodynamic Inactivation of Flavobacterium hydatis as Sensitive and Resistant Species》, the research content is summarized as follows. Antimicrobial photodynamic therapy (aPDT) has been considered as a promising methodol. to fight the multidrug resistance of pathogenic bacteria. The procedure involves a photoactive compound (photosensitizer), the red or near IR spectrum for its activation, and an oxygen environment. In general, reactive oxygen species are toxic to biomols. which feature a mechanism of photodynamic action. The present study evaluates two clin. isolates of Gram-neg. Flavobacteriumhydatis (F. hydatis): a multidrug resistant (R) and a sensitive (S) strain. Both occur in farmed fish, leading to the big production losses because of the inefficacy of antibiotics. Palladium phthalocyanines (PdPcs) with methylpyridiloxy groups linked peripherally (pPdPc) or non-peripherally (nPdPc) were studied with full photodynamic inactivation for 5.0 μM nPdPc toward both F. hydatis, R and S strains (6 log), but with a half of this value (3 log) for 5.0 μM pPdPc and only for F. hydatis, S. In addition to the newly synthesized PdPcs as a “pos. control” was applied a well-known highly effective zinc phthalocyanine (ZnPcMe). ZnPcMe showed optimal photocytotoxicity for inactivation of both F. hydatis R and S. The present study is encouraging for a further development of aPDT with phthalocyanines as an alternative method to antibiotic medication to keep under control the harmful pathogens in aquacultures′ farms.
