      SIBA selectively inhibits spermine synthase, IC50=8 uM. MedChem Express
      SIBA selectively inhibits spermine synthase, IC50=8 uM.;IC50 value: 8 uM;Target: spermine synthaseSIBA is a powerful antiproliferative drug. SIBA has been reported to inhibit cell transformation induced by oncogenic RNA or DNA viruses, the growth of transformed mouse mammary cells, the mitogen-stimulated blastogenesis of lymphocytes and the capping of herpes virus mRNA 161. It has also been demonstrated that an antimalarial activity is exerted by SIBA against Plasmodium falciparum in cultures. MedChem Express HY-18684
