Brequinar, a potent dihydroorotate dehydrogenase (DHODH) inhibitor, has been evaluated in multiple clinical trials as a potential treatment for cancer. To further understand brequinar‐based DHODH inhibition and DHODH′s therapeutic relevance in cancer, we have developed novel brequinar‐based probes. We disclose a 16‐step convergentsynthesis of the first brequinar‐PROTAC and a four‐step approach towards

This invention is in the field of medicinal chemistry. In particular, the invention relates to a new class of small-molecules having a quinazolinedione structure which function as reactive oxygen species (ROS) inducers and inhibitors of mitochondrial activity within cancer cells (e.g., pancreatic cancer cells), and their use as therapeutics for the treatment of cancer (e.g., pancreatic cancer) and other diseases.
Photocaging facilitates non‐invasive and precise spatio‐temporal control over the release of biologically relevant small‐ and macro‐molecules using light. However, sub‐cellular organelles are dispersed in cells in a manner that renders selective light‐irradiation of a complete organelle impractical. Organelle‐specific photocages could provide a powerful method for releasing bioactive molecules in sub‐cellular

Les groupes anioniques et nucleophiles sur la chaine laterale des ylures de triphenylphosphonium provoquent un deplacement de la stereochimie de l'alcene obtenu vers l'isomere trans dans les reactions avec des aldehydes. L'effet est souvent plus important avec des aldehydes aromatiques qu'avec des aldehydes aliphatiques. Les substituants etudies sont les groupes oxydo, carboxylate, amino et amido
