Opaganib is an orally available, aryladamantane compound and selective inhibitor of sphingosine kinase-2 (SK2) with potential antineoplastic activity. Upon administration, opaganib competitively binds to and inhibits SK2, thereby preventing the phosphorylation of the pro-apoptotic amino alcohol sphingosine to sphingosine 1-phosphate (S1P), the lipid mediator that is pro-survival and critical for immunomodulation. This may eventually lead to the induction of apoptosis and may result in an inhibition of cell proliferation in cancer cells overexpressing SK2. SK2 and its isoenzyme SK1 are overexpressed in numerous cancer cell types.

4 Pharmacology and Biochemistry
4.1 Mechanism of Action

Opaganib selectively inhibits [sphingosine kinase-2 (SK2)](https://go.drugbank.com/polypeptides/Q9NRA0). This inhibition blocks the synthesis of sphingosine 1-phosphate (S1P) and its activities (which includes regulation of fundamental biological processes such as cell proliferation, migration, immune cell trafficking, angiogenesis, immune-modulation, and suppression of innate immune responses from T-cells). This drug has dual anti-inflammatory and antiviral activity targeting a host cell component and is unaffected by viral mutation, contributing to minimization of the likelihood of resistance. It is currently being investigated against COVID-19 as it has demonstrated anti-SARS-CoV-2 activity in studies.
