Abstract:

Background Brain-derived estrogen is implicated in pain-related aversion; however, which estrogen receptors mediate this effect remains unclear. This study hypothesized that the different estrogen receptors in the rostral anterior cingulate cortex play distinct roles in pain-related aversion. Methods Formalin-induced conditioned place avoidance and place escape/avoidance paradigms were used to evaluate pain-related aversion in rodents. Immunohistochemistry and Western blotting were used to detect estrogen receptor expression. Patch-clamp recordings were used to examine N-methyl-d-aspartate–med

A new diamine bearing flexible ether, rigid pyridine, and bulky anthrone pendent group, 10,10-bis[4-(4-amino-2-pyridinoxy)phenyl]-9(10 H)-anthrone (BAPPA), was prepared in three steps from anthrone. BAPPA was reacted with six conventional aromatic dianhydrides in N, N-dimethylacetamide (DMAc) to form the corresponding new poly(ether imide)s (PEIs) via the poly(ether amic acid) (PEAA) precursors with inherent viscosities ranging from 0.85 dL g−1 to 1.26 dL g−1 and thermal imidization. All the PEAAs could be cast from DMAc solution and thermally converted into transparent, flexible, and tough PE

Abstract:

Phosphorescent iridium(III) complexes have been widely researched for the fabrication of efficient organic light-emitting diodes (OLEDs). In this work, three red Ir(III) complexes named Ir-1, Ir-2, and Ir-3, with Ir-S-C-S four-membered framework rings, were synthesized efficiently at room temperature within 5 min using sulfur-containing ancillary ligands with electron-donating groups of 9,10-dihydro-9,9-dimethylacridine, phenoxazine, and phenothiazine, respectively. Due to the same main ligand of 4-(4-(trifluoromethyl)phenyl)quinazoline, all Ir(III) complexes showed similar photoluminescence e

These reaction conditions cause carbon–carbon bond cleavage of analogous acyclic β,β-diphenylethyl ethers to give products derived from the diphenylmethyl radical and the α-oxycarbocation intermediat

Based on the synthesized starting 2,4-dimethyl-6-oxo-1,6-dihydropyridin-3-carboxamide crystallizing as a dihydrate, 9 derivatives of it including O- and N-phenacyl substituted products were obtained through original rearrangements and cyclizations. The corresponding oxazolopyridinium perchlorate was obtained from the latter preparation in the presence of acid, from which indolysin was obtained under the action of a nitrogenous base. The obtained molecular and crystal structures of all the compounds were studied by single crystal diffraction: 2,4-dimethyl-6-oxo-1,6-dihydropyridine-3-carboxamide

In organoammonium cations containing two or more N atoms, the H(N) atom introduced by the protonation may engage in an N→H(N)...Y bond to an external acceptor (anion or solvent molecule); in an intra-cation (intra-annular) N→H(N)...N' bond; or in a branched N→H(N)...N',Y bond(s), simultaneously intra-cation and to one or more external acceptors. The outcome of the competition for these bond types is determined by various factors, e.g., the size of the ring to be closed by insertion of the H(N) atom, steric accessibility of H(N), and the H-bond-forming strength of Y. Some of these are discussed
