Hydrogen Peroxide‐Responsive Aminoferrocene Prodrugs

European Journal of Organic Chemistry, EarlyView.
To improve sensitivity toward H2O2, the boronic acid pinacol ester in known aminoferrocene‐based anticancer prodrug 13b is replaced with an α‐ketamide fragment to obtain prodrug 2a and some of its N‐alkylated derivatives. 2a exhibits substantially improved cytotoxicity in vitro toward ovarian cancer A2780 and Burkitt's lymphoma BL‐2 cells.

The Growth of Galaxy Stellar Haloes over 0.2 ≤ z ≤ 1.1

The Astrophysical Journal
Galaxies are predicted to assemble their stellar haloes through the accretion of stellar material from interactions with their cosmic environment. Observations that trace stellar halo buildup probe the processes that drive galaxy size and stellar mass ...

The relation between bar formation, galaxy luminosity, and environment

, 2013
We derive the bar fraction in three different environments ranging from the field to Virgo and Coma clusters, covering an unprecedentedly large range of galaxy luminosities (or, equivalently, stellar masses).

WiggleZ Dark Energy Survey: Cosmological neutrino mass constraint from blue high-redshift galaxies [PDF]

, 2012
The absolute neutrino mass scale is currently unknown, but can be constrained by cosmology. The WiggleZ high redshift, star-forming, and blue galaxy sample offers a complementary data set to previous surveys for performing these measurements, with ...

ATAC‐seq in Emerging Model Organisms: Challenges and Strategies

Journal of Experimental Zoology Part B: Molecular and Developmental Evolution, EarlyView.
Principle of ATAC‐seq (left), overview of arthropod species with published ATAC‐seq data (middle), summary of experimental design (right). ABSTRACT The Assay for Transposase‐Accessible Chromatin with sequencing (ATAC‐seq) is a versatile and widely utilized method for identifying potential regulatory regions, such as promoters and enhancers, within a ...

JWST Reveals Bulge-dominated Star-forming Galaxies at Cosmic Noon

The Astrophysical Journal Letters
Hubble Space Telescope imaging shows that most star-forming galaxies at cosmic noon—the peak of cosmic star formation history—appear disk-dominated, leaving the origin of the dense cores in their quiescent descendants unclear.

On the Possibility of Determining the Distance to the Galactic Center from the Geometry of Spiral Arm Segments

Open Astronomy, 2015
A new approach to determining the solar galactocentric distance, R0, from the geometry of spiral-arm segments is proposed. Geometric aspects of the problem are analyzed and a simplified three-point method for estimating R0 from objects in a spiral ...

Diastereoselectivity in the Synthesis of m‐ and p‐Substituted 3‐Aryl‐2‐trichloromethyl‐1,3‐thiazolidin‐4‐one Sulfoxides With Oxone

Journal of Heterocyclic Chemistry, EarlyView.
Highly selective oxidation of thiazolidin‐4‐ones to sulfoxides and sulfones with Oxone and KMnO4, respectively. ABSTRACT S‐Oxidation of 3‐Aryl‐2‐trichloromethyl‐1,3‐thiazolidin‐4‐ones with Oxone was investigated. For all compounds evaluated, selective oxidation to the sulfoxide versus the sulfone was realized using 3 equivalents of Oxone at room ...
