Doxorubicinol Citrate (Mixture of Diastereomers) (CAS 1242592-26-2 (free base))

Doxorubicinol Citrate (Mixture of Diastereomers) functions as an inhibitor of topoisomerase II enzyme, which plays a role in DNA replication and repair. When Doxorubicinol Citrate (Mixture of Diastereomers) enters the cell, it intercalates into the DNA double helix, disrupting the normal DNA structure and preventing the enzyme from resealing the DNA strands it has cleaved. This interference leads to the accumulation of DNA breaks and the formation of stable enzyme-DNA complexes, ultimately inhibiting DNA replication and transcription. Doxorubicinol Citrate (Mixture of Diastereomers) generates free radicals and reactive oxygen species, causing oxidative damage to cellular components such as DNA, proteins, and lipids. This oxidative stress further contributes to the cytotoxic effects of Doxorubicinol Citrate (Mixture of Diastereomers). The disruption of DNA processes and the induction of oxidative stress collectively lead to cell cycle arrest and apoptosis, ultimately inhibiting the proliferation of cancer cells. Doxorubicinol Citrate (Mixture of Diastereomers) exerts its functional role by interfering with DNA processes and inducing oxidative damage, thereby disrupting cellular pathways and inhibiting the growth of cancer cells.
