Pharmacokinetics of MnTE-2-PyP5+ in plasma (A), liver (B), spleen (C), kidney (D), lung (E), heart (F) and brain (G). Levels of porphyrin are given in µg per mL of plasma or per g of wet tissue. Drug was given at a single intraperitoneal dose of 10 mg/kg to female B6C3F1 mice. Animals were anesthesized, perfused and organs excised. 2 mice were used per data point. Calibration curves were done in plasma and related organs. The known amounts of MnTE-2-PyP5+ were added into the plasma and organ homogenates; the rest of the procedure was identical to the one used for drug-treated mice.
