Angewandte Chemie, EarlyView.A new mode of the palladium/norbornene (Pd/NBE) cooperative catalysis, that is, redox‐neutral difunctionalization of aryl boronic esters with two electrophiles, has been developed, which can be used to streamline the preparation of a functionalized benzoazepane.

Removal of Estrogen Hormones (17β-Estradiol and Estrone) from Aqueous Solutions Using Rice Husk Silica [PDF]
Chemical and Biochemical Engineering Quarterly, 2019 The aim of this study was to investigate the removal of estrogen hormones (17β-estradiol and estrone) from aqueous solutions using rice husk extracted silica. Rice husk was collected from rice factories in Mazandaran province (Iran) and the adsorbent was

Concentrations of nine endogenous steroid hormones in 70-year-old men and women
Endocrine Connections, 2021 Objectives: Circulating concentrations of endogenous steroids have systemic implications on health in elderly. However, population-based age- and ethnic ity-specific data are scarce.

Cobalt‐Catalyzed C─N Bond Formation via Metal‐Hydride Hydrogen Atom Transfer (MHAT)
Angewandte Chemie, EarlyView.Cobalt‐catalyzed metal‐hydride hydrogen atom transfer (Co‐MHAT) converts simple alkenes into C─N bonds under mild, near‐neutral conditions. A shared Co─H‐initiated radical/organocobalt intermediate is channeled into radical trapping, radical‐polar crossover, or radical ligand transfer, unifying hydroamination, hydroazidation, hydroamidation, and remote

Estrone and estradiol concentrations in human ovaries, testes, and adrenals during the first two years of life [PDF]
, 1987 To determine the origin of estrogens in infant blood, we measured estrone (E1) and estradiol (E2) in the gonads of 50 girls and 64 boys who died suddenly between birth and 2 yr of age as well as in the adrenals of 18 of these infant girls and 16 of the ...

Photochemical Reaction Discovery Enabled by the Dynamic Speciation of Copper Complexes
Angewandte Chemie, EarlyView.A strategy for accelerated photochemical reaction discovery is reported that harnesses the dynamic speciation of copper complexes, driven by their labile metal–ligand bonds. This platform simplifies reaction screening by combining an earth‐abundant copper(II) salt with commercially available ligands, which reversibly generate multiple catalytic species

A Receptor-Independent Effect of Estrone Sulfate on the hERG Channel
Journal of Pharmacological Sciences, 2009 We recently reported that physiological concentrations of 17β-estradiol partially down-regulate cardiac rapidly-activating delayed rectifier K+ currents (hERG currents) independently of estrogen-receptor signaling.

Angewandte Chemie, EarlyView.Electrocatalytic polarity inversion of azlactones unlocks their coupling with electron‐rich reaction partners. Triarylamine‐mediated oxidation of the azlactone enolate generates an electrophilic radical intermediate that undergoes selective C4 functionalization with diverse SOMOphiles.
