Provided are a novel compound having CDK8 and/or CDK19 inhibitory activity, and a production method for Tregs. The treatment of T cells with a CDK8 and/or CDK19 inhibitor induces Foxp3 in the T cells. Foxp3.sup.+ T cells can be induced by treating Foxp3.sup.− T cells with the CDK8 and/or CDK19 inhibitor in vitro. Thus, Tregs can be induced.

The treatment of human subjects suffering from COVID-19 comprises the step of administering to the human subjects a medicament selected from the group consisting of 1,3-bis(7-methoxy-4,9-dihydro-3H-pyrido[3,4-b]indol-1-yl)propane, and/or the isomers, tautomers, enantiomers, esters, derivatives, metal complexes, prodrugs, solvates, metabolites, and pharmaceutically acceptable salts thereof. The medicament may also be contacted with SARS-CoV-2 virus for inhibition of the virus.
