A corrosive substance; [CAMEO] Effects during recovery period from a 4-hour, lethal-concentration study of rats include skin lesions, discharge from the nose, and labored breathing; Lesions of the nasal mucosa observed in 2-week inhalation study with rats; No other gross or histopathological changes observed; Considered a severe skin and moderate eye irritant based on studies with rabbits; Not sensitizing to skin of guinea pigs; Dermal LD50 (test substance 69.5% 1,6-Hexanediamine and 30.5% 1,2-Diaminocyclohexane) = 7500 mg/kg in albino rabbits and produced severe irritation with necrosis; [EPA HPVIS] Observations in 28-day feeding with rats at highest tested dose (500 mg/kg) include pale discoloration of liver and increased liver enzymes; Decrease in litter size and increased postnatal loss at highest dose; Caused skin sensitization in guinea pigs (20/20 at 24 hours and 13/20 at 48 hours) [ToxPlanet: TSCATS] Causes burns; Potential skin sensitizer; May cause acute pneumonitis after inhalation; [Alfa Aesar MSDS]

/PLATINUM CO-ORDINATION COMPLEXES/ SHARE THE COMMON FORMULA PTA2X2... THE ACTIVE LIGANDS ARE MONODENTATE ANIONS OF INTERMEDIATE LEAVING ABILITY, WHEREAS THE AMINE A LIGANDS INFLUENCE THE SOLUBILITY OF THE COMPLEX. THE STEREOSPECIFICITY OF THE ANTI-TUMOR EFFECT IS AN IMPORTANT PROPERTY OF THE PLATINUM COMPLEXES. ... INDIRECT EVIDENCE SUGGESTS THAT BINDING TO ADJACENT GUANINE BASES IN THE SAME DNA STRAND IS IMPORTANT TO THE MODE OF ACTION. AFTER INITIAL BINDING TO GUANINE BASES, DNA BECOMES LOCALLY DENATURED AND EXPOSES ADDITIONAL CROSS-LINKING SITES. /PLATINUM COMPLEXES/

...THE TOXIC EFFECT ON ANIMALS OF PLATINUM ITSELF DIFFERS ESSENTIALLY FROM THAT OF THE COMPLEX SALTS. ...THE ACTION OF THESE SALTS IS NOT DUE TO THE SEPARATE COMPONENTS, PLATINUM AND THE BASE, BUT TO THAT OF THE MOLECULE AS A WHOLE ON SENSITIVE TISSUES, AND THEIR PHYSIOLOGICAL EFFECT, THOUGH VARYING IN DEGREE, IS IDENTICAL IN CHARACTER. ...AN INCREASE IN THE VALENCY OF THE AMMONIUM COMPONENT WAS ASSOCIATED WITH A STRONGER "CURARE-LIKE" ACTION WHILE A CHANGE IN THE VALENCY OF THE PLATINUM HAD NO INFLUENCE ON THE TOXIC EFFECT. /PLATINUM COMPLEXES/
