The Acute Toxicity of Novel Platinum(II) Complexes

This study was conducted to examine novel Pt(II) complexes, (KHPC-002; [Pt(trans-1-dach) (DPPE)]. 2NO$_3$, KHPC-005;[Pt(cis-1-dach)(DPPP)]. 2NO$_3$ and KHPC-006; [Pt(cis-1-dach) (DPPE)]. 2NO$_3$) for their acute toxicities and toxicological profiles in preclinical studies. In male and female mice given a single intraperitoneal administration of KHPC-002, KHPC-005 and LHPC-006, we determined that LD$\_$50/ values of pt(II) complexes were 295.5mg/kg(M), 350.4mg/kg(F);KHPC-002, 158.7mg/kg(M), 157.7mg/kg(F); KHPC-005, 574.8mg/kg(M), 596.5 mg/kg (F); KHPC-006, respectively. In gross and histopathological examination on dead animals, no abnormal changes were observed in any organs.
