Tozasertib, originally developed as VX-680 by Vertex (Cambridge, MA) and later renamed MK-0457 by Merck (Whitehouse Station, NY), was the first aurora kinase inhibitor to be tested in clinical trials. The drug, a pyrimidine derivative, has affinity for all aurora family members at nanomolar concentrations with inhibitory constant values (Ki(app)) of 0.6, 18, and 4.6 nM for aurora A, aurora B, and aurora C, respectively. Preclinical studies confirmed that tozasertib inhibited both aurora A and aurora B kinase activity, and activity has been reported against prostate, thyroid, ovarian, and oral squamous cancer cell lines. Upon treatment with tozasertib, cells accumulate with a 4N DNA content due to a failure of cytokinesis. This ultimately leads to apoptosis, preferentially in cells with a compromised p53 function. Tozasertib is an anticancer chemotherapeutic pan-aurora kinase (AurK) inhibitor that also inhibits FMS-like tyrosine kinase 3 (FLT3) and Abl. Tozasertib is currently in clinical trials as a potential treatment for acute lymphoblastic leukemia (ALL). In cellular models of cancer, tozasertib activates caspase-3 and PARP and decreases expression of HDAC, increasing apoptosis and inhibiting cell growth. In other cellular models, tozasertib inhibits cell proliferation and metastasis by blocking downstream ERK signaling and downregulating cdc25c and cyclin B. This compound also decreases tumor growth in an in vivo model of prostate cancer.

Gliflumide is a compound with a long-lasting hypoglycemic effect. This blood glucose lowering sulfonamide has shown a large decrease of blood glucose levels in healthy volunteers who where administered the drug orally or intravenously. A very similar reaction but delayed and prolonged response was observed for this drug compared to other insulin secretion-stimulating compounds (such as glibenclamide). High affinity of gliflumide to plasma proteins has been suggested to contribute to this delayed activity.

Mesocarb (sydnocarb or 3-(beta-phenylisopropyl)-N-phenylcarbamoylsydnonimine) is a psychomotor stimulant N-alkylated amphetamine derivative. Mesocarb is a selective inhibitor of dopamine uptake, it potently blocks dopamine transporter. It is very likely that mesocarb is being used by drug addicts. Mesocarb is included in the World Anti-Doping Agency’s list of substances and methods that are prohibited in sports. It is used in Russia for the treatment of a variety of neuropsychiatric comorbidities.
