Synthesis of Some Substituted Benz/Acetamidines [PDF]

مجلة التربية والعلم, 2006
In the present work the synthesis of subtituted acetamidines was achieved. Phthalic anhydride was treated with p-aminobenzoic acid or glycine to give the corresponding acid which then converted to acid chloride with thionyl chloride.

Remote Control of Eukaryotic Gene Expression by a Modular Ultrasound‐Responsive RNA Toolkit

Angewandte Chemie, EarlyView.
A modular RNA‐based sonogenetic toolkit enables remote control of gene expression in eukaryotes by releasing small molecule modulators from ultrasound‐responsive carriers. These modulators activate engineered mRNA elements such as riboswitches, leading to tunable protein expression.

Conditional Stabilization of the Hypoxia‐Inducible Factor HIF1α— Photoswitchable Stapled Peptides Prevent Elongin BC–Mediated Degradation

Angewandte Chemie, EarlyView.
Visible‐light photoswitchable peptides enable the stabilization of the hydroxylated hypoxia transcription factor 1α (HIF1α—OH) by targeting the pVHL‐EloBC interaction. Significant differences in conformation, binding, and transcription of HIF‐targeted genes between the photostationary states (PSS) were demonstrated.
