DM-1157
DM-1157 is an orally active asymmetric bisquinoline heme inhibitor with a IC50 of 1.6 μM and a Kd of 1.7 μM. DM-1157 binds to heme dimers in solution, inhibits β-hematin formation, suppresses hemozoin formation in the digestive vacuole of Plasmodium falciparum, accumulates in the digestive vacuole of Plasmodium falciparum, induces enlargement of the digestive vacuole of Plasmodium falciparum, and inhibits the growth of Chloroquine (HY-17589A)-sensitive and resistant Plasmodium falciparum strains. DM-1157 can be used for the research of malaria and Plasmodium falciparum-type malaria.

Biological Activity
DM-1157 (Compound 22) (0.9-1.8 nM; 72 h) potently inhibits growth of chloroquine-sensitive D6, chloroquine-resistant Dd2, and chloroquine-resistant 7G8 Plasmodium falciparum strains in vitro with normalized IC50 values of 0.9 nM, 1.6 nM, and 1.8 nM, respectively[1].
DM-1157 (6500 nM) has a low in vitro cytotoxicity against murine spleenic lymphocytes, with a cytotoxicity IC50 of 6500 nM and a therapeutic index of 4060 relative to its antimalarial activity against Dd2 Plasmodium falciparum[1].
DM-1157 (10-50 nM; 24 h) potently inhibits hemozoin production in synchronized chloroquine-sensitive D6 and chloroquine-resistant Dd2 Plasmodium falciparum strains in vitro, with near-complete inhibition at 10 nM and complete inhibition at 50 nM, while inducing digestive vacuole enlargement[1].
DM-1157 (72 h) potently inhibits in vitro growth of chloroquine-sensitive P. falciparum D6 (IC50 = 0.2 nM) and chloroquine-resistant P. falciparum Dd2 (IC50 = 2.2 nM) and 7G8 (IC50 = 1.8 nM) strains, and shows cytotoxicity against mouse spleen lymphocytes with an LC50 of 6500 nM[2].
