Phenylstyrylpyrimidine derivatives as potential multipotent therapeutics for Alzheimer's disease.

Alzheimer's disease (AD) is a multifactorial neurological disorder that affects millions of people worldwide. Despite extensive research efforts, there are currently no effective disease-modifying therapeutics available for the complete cure of AD. In the current study, we have designed and synthesized a series of phenyl-styryl-pyrimidine derivatives as potential multifunctional agents against different targets of AD.

Design, synthesis, and anticancer assessment of structural analogues of ()-1-((3,4,5-trimethoxybenzylidene)amino)-4-(3,4,5-trimethoxyphenyl)imidazo[1,2-]quinoxaline-2-carbonitrile (6b), an imidazo[1,2-]quinoxaline-based non-covalent EGFR inhibitor.

In our quest to find improved anticancer therapeutics, we expedite the lead optimization of ()-1-((3,4,5-trimethoxybenzylidene)amino)-4-(3,4,5-trimethoxyphenyl)imidazo[1,2-]quinoxaline-2-carbonitrile (6b), an EGFR inhibitor previously discovered in our laboratory through an in-house screening program. The lead optimization was rationally initiated considering the catalytic site of EGFR. We synthesized twenty-nine new analogues of 6b and assessed their anticancer activities.

Observation of magnetic vortex configuration in non-stoichiometric FeO nanospheres.

Theoretical and micromagnetic simulation studies of magnetic nanospheres with vortex configurations suggest that such nanostructured materials have technological advantages over conventional nanosystems for applications based on high-power-rate absorption and subsequent emission. However, full experimental evidence of magnetic vortex configurations in spheres of submicrometer size is still lacking. Here, we report the microwave irradiation fabrication of FeO nanospheres and establish their magnetic vortex configuration based on experimental results, theoretical analysis, and micromagnetic simulations.
