Synthesis and immunosuppressive activity evaluation of substituted N-imidazolidin-2-ones and N-tetrahydropyrimidin-2(1H)-ones

摘要

Seventeen compounds with either an imidazolin-2-one or a tetrahydropyrimidin-2(1H)-one scaffold were synthesized and evaluated for their immunosuppressive activity in a concanavallin A (ConA)-stimulated mouse splenocytes proliferation test. Three of these molecules exerted a significant activity at 90 μM. All the compounds of the tetrahydropyrimidin-2(1H)-one series have turned out to be inactive showing the crucial role of the imidazolidin-2-one scaffold in the induction of an immunosuppressive activity.
