Daunorubicin, also known as daunomycin, is a chemotherapy medication used to treat cancer. Specifically, it is used for acute myeloid leukemia (AML), acute lymphocytic leukemia (ALL), chronic myelogenous leukemia (CML), and Kaposi's sarcoma. Similar to doxorubicin, daunorubicin interacts with DNA by intercalation and inhibition of macromolecular biosynthesis. This inhibits the progression of the enzyme topoisomerase II, which relaxes supercoils in DNA for transcription. Daunorubicin stabilizes the topoisomerase II complex after it has broken the DNA chain for replication, preventing the DNA double helix from being resealed and thereby stopping the process of replication. On binding to DNA, daunomycin intercalates, with its daunosamine residue directed toward the minor groove. It has the highest preference for two adjacent G/C base pairs flanked on the 5' side by an A/T base pair. Daunorubicin should only be administered in a rapid intravenous infusion. It should not be administered intramuscularly or subcutaneously, since it may cause extensive tissue necrosis. It should also never be administered intrathecally (into the spinal canal), as this will cause extensive damage to the nervous system and may lead to death.

Aldoxorubicin (INNO-206) is a tumor-targeted doxorubicin conjugate developed by CytRx for treating relapsed and refractory sarcomas, especially L-sarcomas. Aldoxorubicin is a rationally-engineered cytotoxic which delivers a well-established anti-cancer agent, doxorubicin, into the tumor. Currently, in late-stage clinical trials, Aldoxorubicin appears to overcome the key limitations of doxorubicin, including cumulative dose restrictions. Aldoxorubicin utilizes an acid-sensitive linker that selectively binds to albumin, which may allow the cytotoxic payload to preferentially accumulate in the tumor and potentially spare the surrounding healthy tissue. This mechanism leverages the tumor's low pH environment and accompanying dependency upon circulating albumin to fuel growth, to enable the delivery of multifold times the standard dosing of doxorubicin. The preferential uptake of Aldoxorubicin by tumor tissue and the acid sensitive release of doxorubicin allow for Aldoxorubicin to be a very promising anticancer agent. In phase I and II trials, Aldoxorubicin demonstrates superior efficacy over doxorubicin. Although the studies were not powered for OS, Aldoxorubicin shows improved PFS and tumor response in comparison to doxorubicin. The safety profile was also comparable to that of doxorubicin. Similarly, results from the recent phase III study showed a benefit in PFS in the leiomyosarcoma subtypes.

Acetone (or propanone) is the smallest and simplest ketone, which is used in cosmetic as a nail polish remover. Acetone is produced within the body because of the breakdown of stored fats and lipids as a source of energy. Such conditions as physical exercise and prolonged dieting, which lead to cleavage of fat within the body, may result in higher than average amounts of acetone in the bloodstream. The concentration of acetone in the environment doesn’t cause a neurotoxic, carcinogenic, or reproductive health hazard effect. In addition, experiments on rodents have shown that acetone possesses anticonvulsant properties.
