Beyond crystallography: diffractive imaging using coherent x-ray light sources [PDF]

, 2015
X-ray crystallography has been central to the development of many fields of science over the past century. It has now matured to a point that as long as good-quality crystals are available, their atomic structure can be routinely determined in three ...

Biomimetic Copper‐Doped Nano‐Aluminum Adjuvant Potentiates Therapy in Chemoresistant Acute Myeloid Leukemia

Advanced Healthcare Materials, EarlyView.
We developed a novel copper‐doped aluminum nano‐adjuvant (CuNA) to overcome cytarabine resistance in acute myeloid leukemia (AML). CuNA effectively sensitizes drug‐resistant AML cells to cytarabine by inducing mitochondrial dysfunction and inhibiting HMGCR/GPX4 to amplify ferroptosis.

Crystal structure and Hirshfeld surface analysis of a pyridiniminium bromide salt: 1-[2-(adamantan-1-yl)-2-oxoethyl]pyridin-4-iminium bromide

Acta Crystallographica Section E: Crystallographic Communications, 2018
In the cation of the title salt, C17H23N2O+·Br−, the adamantyl moiety and the pyridiniminium ring are inclined to the ketone bridge by torsion angles of −78.1 (2) (C—C—C=O) and 58.3 (2)° (C—C—N—C), respectively, and the ketone bridge has a C—C—C—N ...

The crystal structure of Acinetobacter baumannii bacterioferritin reveals a heteropolymer of bacterioferritin and ferritin subunits

Scientific Reports
Iron storage proteins, e.g., vertebrate ferritin, and the ferritin-like bacterioferritin (Bfr) and bacterial ferritin (Ftn), are spherical, hollow proteins that catalyze the oxidation of Fe2+ at binuclear iron ferroxidase centers (FOC) and store the Fe3+

4-Cyano-3-fluorophenyl 4-(hexadecyloxy)benzoate

Acta Crystallographica Section E, 2014
In the title compound, C30H40FNO3, the dihedral angle between the benzene rings is 57.76 (7)°. The alkyl chain adopts an all-trans conformation. In the crystal, molecules are linked by pairs of C—H...O hydrogen bonds, forming inversion dimers.
