A Prelude to Biogermylene Chemistry
Preprints are manuscripts made publicly available before they have been submitted for formal peer review and publication. They might contain new research findings or data. Preprints can be a draft or final version of an author's research but must not have been accepted for publication at the time of submission.
Abstract: The biological applications of germylenes remain an unconceivable domain owing to their unstable nature. We report the isolation of air, water, and culture-medium stable germylene DPMGeOH (3) and its potential biological application (DPM = dipyrromethene ligand). Compound 3 exhibits antiproliferative effects comparable to that of cisplatin in human cancer cells. The cytotoxicity of compound 3 on normal epithelial cells is minimal and is similar to that of the currently used anti-cancer drugs. These findings provide a framework for a plethora of biological studies using germylenes and have important implications for low-valent main group chemistry.
