Cyclophilins are cellular (host) peptidyl-prolyl cis/trans isomerases (molecular chaperones) involved in protein folding, maturation, and trafficking. Cyclophilins have been shown to play a key role in the lifecycle of many coronaviruses, including human coronaviruses 229E (HCoV-229E) and NL-63 (HCoV-NL63), feline infectious peritonitis coronavirus (FPIV), SARS-CoV and Middle-East-Respiratory-Syndrome coronavirus (MERS-CoV). Cyclosporin A (CsA), a potent cyclophilin inhibitor, blocks the replication of various coronaviruses in vitro, including HCoV-229E, HCoV-NL63, FPIV, mouse hepatitis virus (MHV), avian infectious bronchitis virus, and SARS-CoV. Alisporivir is a non-immunosuppressive analogue of CsA with potent cyclophilin inhibition properties. In vitro, alisporivir inhibits the replication of HCoV-229E, HCoV-NL63, MHV, SARS-CoV and MERS-CoV at low micromolar concentrations without cytotoxic effect. Although alisporivir has not demonstrated activity against coronaviruses in in vivo models to date, recent experiments showed that alisporivir bears concentration-dependent properties against CoV-2 in vitro. Preclinical pharmacology data indicate that, after oral administration, alisporivir is widely distributed in the whole body, including the lungs. Furthermore, the EC90 of alisporivir against SARS-CoV-2 in VeroE6 cells appears to be clinically achievable in patients. In addition, because alisporivir inhibits all cellular cyclophilins, it also blocks mitochondrial cyclophilin-D, a key regulator of mitochondrial permeability transition pore (mPTP) opening, a mechanism involved in triggering cell death. Therefore, besides its antiviral properties, alisporivir may also be effective in preventing lung tissue damage.
