[2.2]Paracyclophane derivatives containing tetrathiafulvalene moieties
Beilstein Journal of Organic Chemistry, 2015 The synthesis of [2.2]paracyclophane derivatives containing tetrathiafulvalene units has been accomplished by the coupling reaction of 4-([2.2]paracyclophan-4-yl)-1,3-dithiol-2-thione in the presence of trimethylphosphite.

ChemistryEurope, Volume 4, Issue 3, March 2026.A divergent halogen‐promoted intramolecular sulfenylation of dienamines enables access to two unprecedented families of benzo[4,5]imidazo[2,1‐b]thiazole. The resulting scaffolds feature distinct chiral elements, either a quaternary stereocenter in the case of spirolactones, or a stereogenic axis for heteroaryl‐alkenes, with high configurational ...

Gold–Thiopurine and Thioguanine Platforms for Chemotherapy and Photodynamic Therapy
ChemistryEurope, Volume 4, Issue 3, March 2026.Gold(I)–thiopurine complexes bearing chromophores and phosphine or N‐heterocyclic carbene ligands were developed as multimodal chemo‐photodynamic agents. They show good stability, moderate lipophilicity, and tunable photoresponse. 6‐TG enhances dark cytotoxicity, 6‐MP improves phototoxicity, and PPh3/NBD provide the most efficient photoactivation ...

New Phytologist, Volume 249, Issue 6, Page 3091-3103, March 2026.Summary Temperature influences the distribution and performance of both plants and insect herbivores. Consequently, plant–herbivore interactions are likely to vary across thermal gradients, which could affect the evolution of plant defense. Furthermore, temperature fluctuations may elicit immediate changes in defense.

A Non-Covalent Antibody Complex for the Delivery of anti-cancer drugs [PDF]
, 2019 Antibody drug conjugates (ADCs), which are obtained by coupling a potent cytotoxic agent to a monoclonal antibody (mAb), are traditionally bound in a random way to lysine or cysteine residues, with the final product's heterogeneity having an important ...
