Physalin H

Physalin H is an Hh signaling inhibitor blocks GLI1-DNA-complex formation, it also strong quinone reductase induction activity with IR (Induction ratio, QR induction activity) value of 3.74±0.02. Physalin H shows immunosuppressive effects on T cells both in vitro and in vivo, and the immunosuppressive activity might be attributed to the suppression of T cell activation and proliferation, the modulation of Th1/Th2 cytokine balance and the induction of HO-1 in T cells. Physalin H shows significant in vitro leishmanicidal activities (0.92-19.4 microg/ml) against promastigotes of Leishmania major.Physalin H shows cytotoxic activity against a panel of human and murine cancer cell lines.
