Synthesis and Antitumor Evaluation of 6-Aryl-substituted benzo[j]phenanthridine- and Benzo[g]pyrimido[4,5-c]isoquinolinequinones

Molecules, 2012
A variety of novel 6-arylsubstituted benzo[j]phenanthridine- and benzo[g]-pyrimido[4,5-c]isoquinolinequinones were synthesized from 1,4-naphthoquinone, aryl-aldehydes and enaminones via a two-step synthetic approach.

The Application of Metal–Organic Frameworks as Drug Delivery Systems: From the Perspective of Molecular Dynamics Simulations

MedComm, Volume 7, Issue 4, April 2026.
This review article provides a comprehensive exploration of the synergistic integration of molecular dynamics (MD) simulations and metal–organic frameworks (MOFs) to advance the design and optimization of nanoscale drug delivery systems (DDSs). We believe this work will be of significant interest to researchers in nanomedicine, computational biology ...

Tunably strained metallacycles enable modular differentiation of aza-arene C–H bonds

Nature Communications, 2023
The precise activation of C–H bonds will eventually provide chemists with transformative methods to access complex molecular architectures. Current approaches to selective C–H activation relying on directing groups are effective for the generation of ...

Interplay of ortho- with spiro-cyclisation during iminyl radical closures onto arenes and heteroarenes

Beilstein Journal of Organic Chemistry, 2013
Sensitised photolyses of ethoxycarbonyl oximes of aromatic and heteroaromatic ketones yielded iminyl radicals, which were characterised by EPR spectroscopy.

The individual components of commercial isometamidium do not possess stronger trypanocidal activity than the mixture, nor bypass isometamidium resistance

International Journal for Parasitology: Drugs and Drug Resistance, 2019
The four components present in the trypanocidal treatment Samorin, the commercially available formulation of isometamidium, were separated and purified by column chromatography.

Doping of Graphene Nanoribbons via Functional Group Edge Modification

, 2017
We report on the on-surface synthesis of 7 armchair graphene nanoribbons (7-AGNRs) substituted with nitrile (CN) functional groups. The CN groups are attached to the GNR backbone by modifying the 7-AGNR precursor.

Ir(III) Complexes Convert Cold to Hot Tumors via Ferroptosis/Necroptosis‐Driven Immunogenic Cell Death and Photosensitized CD47 Downregulation

Advanced Science, Volume 13, Issue 8, 9 February 2026.
Red‐light‐activated Ir1 overcomes hypoxia tolerance and adapts to the immunosuppressive tumor microenvironment, converting immunologically cold tumors into inflamed hot microenvironments. This conversion is driven by synergistic induction of immunogenic cell death through coordinated ferroptosis‐necroptosis pathways and spatiotemporally controlled ...

MitoNeoD:a mitochondria-targeted superoxide probe [PDF]

, 2017
Mitochondrial superoxide (O2⋅−) underlies much oxidative damage and redox signaling. Fluorescent probes can detect O2⋅−, but are of limited applicability in vivo, while in cells their usefulness is constrained by side reactions and DNA intercalation.
