Cytotoxic cyclic depsipeptides from the Australian marine sponge Neamphius huxleyi

Three new cyclic depsipeptides, neamphamides B (2), C (3), and D (4), were isolated from the Australian sponge Neamphius huxleyi. The planar structural characterization of these molecules was elucidated using 2D NMR experiments and ESI-FTICR-MSn. Their configurations were determined by Marfey’s method and J-based NMR analysis. These new metabolites inhibited the growth of human cell lines (A549, HeLa, LNCaP, PC3, and NFF) with IC50 values ranging from 88 to 370 nM. However, neamphamide D causes A549 cell proliferation at subcytotoxic doses and should be treated cautiously as a cytotoxic compound.

Minimizing Side Product Formation in Alkyne Functionalization of Ruthenium Complexes by Introduction of Protecting Groups

The synthesis of alkyne functionalized bipyridine ruthenium complexes are reported. The improved synthetic approach through application of stable protecting groups prevents formation of possible side products while facilitating purification. By applying copper-catalysed azide-alkyne cycloaddition reactions (CuAAC) pyrene units with flexible alkyl linkers are introduced at the periphery of the complex, opening up various applications including surface immobilization and DNA intercalation. All complexes are characterized structurally as well as photophysically, especially regarding the influence of the introduced alkyne and triazolyl substituents on their photophysical behavior.

Preparation of MFI type zeolite with hierarchical pores system as new supports for deposition of metal clusters

A method of preparation of high-silica zeolite crystals (MFI type) containing meso-/macrovoids is described. The modification of the crystals was obtained during the hydrothermal synthesis with the use of different meso-/macro matrices like mono- and polydispersed carbon particles. Presence of the meso-/macrovoids in the crystals was directly proved with TEM analysis. The modified MFI zeolite crystals could be successfully used for the deposition of highly dispersed metal (Pd) phase when the impregnation with a metal salt solution (the incipient wetness technique) followed by the reduction in an H2/N2 stream was applied. The deposition of small (2-4 nm) Pd clusters inside the meso-/macrovoids was proved with HRTEM and STEM/HAADF technique. The deposition of Pd in the crystals limited the size and number of bigger metal particles deposited at the outer surface.

Spatiotemporal development of physical, chemical, and biological characteristics of stormwater plumes in Santa Monica Bay, California (USA)

This study characterized stormwater plume development and associated phytoplankton dynamics in a coastal marine ecosystem through shipboard monitoring. We focused on plumes within Santa Monica Bay, California (USA), a coastal system that is subject to rapid pulses of untreated runoff from the urbanized watershed of Los Angeles during the winter rainy season. The physical, chemical, and biological signatures of stormwater plumes were tracked over time after each of 4 precipitation events ranging in magnitude from 1.5 cm to 9 cm. Low salinity surface plumes persisted in Santa Monica Bay for at least 2 to 5 days over spatial scales of up to 15 km. This is consistent with a 6-day residence time for surface water plume parcels, which was estimated from a drifter trajectory in the bay. Shipboard sampling and salinity measurements in the surf zone showed that plumes often persisted even longer nearshore. Plume waters were generally characterized by higher concentrations of dissolved nitrogen, colored dissolved organic matter, and higher light attenuation than non-plume waters. The magnitude of the effect of stormwater runoff on phytoplankton dynamics was dependent on the size of each storm and subsequent residence time of runoff within the bay. Rain events led to increases in primary productivity, phytoplankton biomass, and specifically, increases in diatom biomass, as measured by concentrations of biogenic silica.

Optimization of Ultrasound-Assisted Oxidation of Thiophene Using Phase Transfer Catalyst

Thiophene oxidation with hydrogen peroxide was studied with tetrabutylammonium bromide, phenyltrimethylammonium tribromide, ethyltriphenylphosphonium bromide, benzyltrimethylammonium tribromide, tetrapropylammonium bromide, tetrabutylammonium hydrogensulphate, and 18-crown-6-ether as phase transfer catalysts (PTC) under ultrasound. Highest conversion (82.59%) was achieved with benzyltrimethylammonium tribromide at 1,200 rpm and 30 kHz frequency. The effect of parameters such as oxidant-to-sulphur mole ratio, intensity of ultrasound, stirrer speed, catalyst amount, and operating temperature on oxidation was explored by using benzyltrimethylammonium tribromide. Central composite design was chosen for optimization of conversion using temperature, catalyst loading, and molar ratio. The pseudo first-order kinetics with apparent activation energy of 79.55 kJ/mol was established.
