Crystal structure of pyriproxyfen [PDF]

Acta Crystallographica Section E Crystallographic Communications, 2015
In the title compound {systematic name: 4-phenoxyphenyl (RS)-2-[(pyridin-2-yl)oxy]propyl ether}, C20H19NO3, which is a juvenile hormone mimic and insecticide, the dihedral angles between the plane of the central benene ring and those of the pendant pyridine ring and phenyl ring are 78.09 (6) and 82.14 (8)°, respectively. The conformation of the O—C—C—O

Jahn-Teller distortion in Cs4C60 studied by vibrational spectroscopy [PDF]

, 2002
We have measured the infrared spectra of Cs(4)C(60) in the temperature range 220 - 450 K. Two anomalies in the low-frequency modes at 270 K and 400 K point to changes in molecular or crystal structure.

pH‐mediated activation of the lysosomal arginine sensor SLC38A9

FEBS Letters, EarlyView.
Cells monitor nutrient levels via the lysosomal transporter SLC38A9 to activate the mechanistic target of rapamycin complex 1 (mTORC1). This study reveals that SLC38A9 function is regulated by pH. We identified histidine 544 as a critical pH sensor that undergoes conformational changes to control amino acid efflux from lysosomes; therefore, it ...

Carbon nitride quantum dots decorated with cyano groups for boosting photocatalytic hydrogen peroxide production

Green Energy & Environment
The photocatalytic hydrogen peroxide (H2O2) production by graphitic carbon nitride is a sustainable and environment-benign alternative approach of conventional anthraquinone autoxidation technology, but it is great challenges to promote two-electron O2 ...

(4Z)-4-(2-Oxopropylidene)-1,3-bis(prop-2-en-1-yl)-2,3,4,5-tetrahydro-1H-1,5-benzodiazepin-2-one

IUCrData, 2017
In the title compound, C18H20N2O2, the diazepin-2-one ring adopts a tub conformation. The conformation of the acetyl group is partially determined by an intramolecular N—H...O hydrogen bond.

Degradation mechanism of the von Willebrand factor A2 domain by nattokinase

FEBS Letters, EarlyView.
Nattokinase, a natto‐derived protease, exhibits potent antithrombotic effects. This study demonstrates that nattokinase directly cleaves the von Willebrand factor (vWF) A2 domain in vitro. Unlike the native regulator ADAMTS13, nattokinase degrades folded vWF independently of shear stress.

Crystal structure of fluroxypyr [PDF]

Acta Crystallographica Section E Crystallographic Communications, 2016
In the title pyridine herbicide {systematic name: 2-[(4-amino-3,5-dichloro-6-fluoropyridin-2-yl)oxy]acetic acid}, C7H5Cl2FN2O3, the mean plane of the carboxylic acid substituent and the pyridyl ring plane subtend a dihedral angle of 77.5 (1)°. In the crystal, pairs of O—H...O hydrogen bonds form inversion dimers withR22(8) ring motifs.
