Damage and Repair in Informational Poly(N‐substituted urethane)s

The degradation and repair of uniform sequence‐defined poly(N‐substituted urethane)s was studied. Polymers containing an ω‐OH end‐group and only ethyl carbamate main‐chain repeat units rapidly degrade in NaOH solution through an ω→α depolymerization mechanism with no apparent sign of random chain cleavage...

La géométrie moléculaire de solides organiques révélée par RMN

Les propriétés d’un matériau dépendent de sa structure. Cependant, la structure atomique ou moléculaire d’un solide reste très difficile à déterminer lorsque le matériau à analyser ne forme pas de cristaux de taille et qualité élevées, limitant ainsi la possibilité de développer de nouveaux matériaux pour des applications ciblées...

A new method to triangulate Host:Guest 1:1 complexes comprising free radicals, by means of cucurbituril macrocycles

While the scientific literature is replete with examples of host:guest 1:1 complexes, their subsequent self-assembly into advanced architectures remains elusive. Cucurbiturils have now been observed to be triangulated as 3:3 complexes and nitroxide free radicals are non
innocent in that process.

Targeting Lonidamine to Mitochondria Mitigates Lung Tumorigenesis and Brain Metastasis

"A new hope for Lung cancer".

Lung cancer often has a poor prognosis, with brain metastases a major reason for mortality. We modified lonidamine (LND), an antiglycolytic drug with limited efficacy, to mitochondria-targeted mito-lonidamine (Mito-LND) which is 100-fold more potent.
