Synthesis, crystal structure, Hirshfeld surface analysis, DFT and NBO study of ethyl 1-(4-fluorophenyl)-4-[(4-fluorophenyl)amino]-2,6-diphenyl-1,2,5,6-tetrahydropyridine-3-carboxylate

Acta Crystallographica Section E: Crystallographic Communications, 2023
The title compound, C32H28F2N2O2, a highly functionalized tetrahydropyridine, was synthesized by a one-pot multi-component reaction of 4-fluoroaniline, ethyl acetoacetate and benzaldehyde at room temperature using sodium lauryl sulfate as a catalyst. The

Lifting defects for nonstable K_0-theory of exchange rings and C*-algebras

, 2011
The assignment (nonstable K_0-theory), that to a ring R associates the monoid V(R) of Murray-von Neumann equivalence classes of idempotent infinite matrices with only finitely nonzero entries over R, extends naturally to a functor. We prove the following

Crystal structure and optical properties of fused-ring chalcone (E)-3-(anthracen-9-yl)-1-(4-nitrophenyl)prop-2-en-1-one

Acta Crystallographica Section E: Crystallographic Communications, 2019
The title compound, C23H15NO3, adopts an s-cis conformation with respect to the ethylene C=C and carbonyl C=O double bonds in the enone unit. The molecule is significantly twisted with a dihedral angle of 48.63 (14)° between the anthracene ring system ...

Modifications in FLAP's second cytosolic loop influence 5‐LOX interaction, inhibitor binding, and leukotriene formation

FEBS Letters, EarlyView.
The enzyme 5‐lipoxygenase (5‐LOX) catalyzes the first step in the biosynthesis of leukotrienes (LTs) involved in inflammatory pathophysiology. After cellular stimulation, 5‐LOX translocates to the nucleus, interacting with the 5‐LOX‐activating protein (FLAP) to form LTA4 from arachidonic acid (AA).

Calculated optical properties of donor molecules based on benzo[1,2-b:4,5-b′]dithiophene and its derivatives

AIP Advances, 2021
In this work, we study the light absorption properties of different novel molecules based on benzo[1,2-b:4,5-b′]dithiophene (BDT), namely, BT-2F, BTRCl, and BTTzR, which hold great promise as electron-donor materials in organic solar cells.

Ultracompact two‐way and four‐way SIW/HMSIW power dividers loaded by complementary split‐ring resonators

International journal of RF and microwave computer-aided engineering, 2019
In this paper, two ultracompact power dividers based on the substrate integrated waveguide (SIW) and half‐mode SIW (HMSIW) technologies loaded by complementary split‐ring resonators (CSRRs) are presented.

In vivo evidence for glycyl radical insertion into a catalytically inactive variant of pyruvate formate‐lyase

FEBS Letters, EarlyView.
Dimeric pyruvate formate‐lyase cleaves pyruvate using a radical‐based mechanism. G734 serves as a radical storage location, and the radical is transferred to the catalytic C419 residue. Mutation of the C418‐C419 pair causes loss of enzyme activity, but does not impede radical introduction onto G734. Therefore, cis‐ but not trans‐radical transfer occurs

Combinatorial Sutured TQFT as Exterior Algebra [PDF]

, 2012
The idea of a sutured topological quantum field theory was introduced by Honda, Kazez and Mati\'c (2008). A sutured TQFT associates a group to each sutured surface and an element of this group to each dividing set on this surface.

GINZBURG-LANDAU THEORY OF VORTICES IN $d$-WAVE SUPERCONDUCTORS

, 1995
Ginzburg-Landau theory is used to study the properties of single vortices and of the Abrikosov vortex lattice in a $d_{x^2-y^2}$ superconductor. For a single vortex, the $s$-wave order parameter has the expected four-lobe structure in a ring around the ...

Completions of Z/(p)-Tate cohomology of periodic spectra [PDF]

, 1998
We construct splittings of some completions of the Z/(p)-Tate cohomology of E(n) and some related spectra. In particular, we split (a completion of) tE(n) as a (completion of) a wedge of E(n-1)'s as a spectrum, where t is shorthand for the fixed points ...
