This report describes a method for Ni-catalyzed intramolecular decarbonylative coupling, which enables the conversion of areneselenol esters to diaryl selenides. The inexpensive and readily available catalyst can be employed under mild reaction conditions for the construction of structurally diverse diaryl selenides, including heterocyclic and natural product derivatives. (Figure presented.).

Sheet 10, (2018/03/09)
A class of cyanosteroid compounds that efficiently inhibit ghrelin acylation by ghrelin O-acyltransferase. The compounds have a steroid scaffold with α,β-unsaturated ketone in the A ring position such an a-cyanoenone. Exemplary compounds include (5S,8S,9S,10S, 13S,14S)-10,13-dimethyl-3-oxo-4,5,6,7,8,9,10,11,12,13,14,15,16,17- tetradecahydro-3H-cyclopenta[a]phenanthrene-2-carbonitrile.

N-Methyl-d-aspartate receptors (NMDARs) are glutamate-gated ion channels that play a crucial role in excitatory synaptic transmission. However, the overactivation of NMDARs can lead to excitotoxic cell damage/death, and as such, they play a role in numerous neuropathological conditions. The activity of NMDARs is known to be influenced by a wide variety of allosteric modulators, including neurosteroids, which in turn makes them promising therapeutic targets. In this study, we describe a new class of neurosteroid analogues which possess structural modifications in the steroid D-ring region. These analogues were tested on recombinant GluN1/GluN2B receptors to evaluate the structure-activity relationship. Our results demonstrate that there is a strong correlation between this new structural feature and the in vitro activity, as all tested compounds were evaluated as more potent inhibitors of NMDA-induced currents (IC50 values varying from 90 nM to 5.4 μM) than the known endogeneous neurosteroid-pregnanolone sulfate (IC50 = 24.6 μM).
