Distribution of K027, a hydrophilic, positively charged compound is monitored in the body of pregnant mice using high-performance liquid chromatography (HPLC). Intraperitoneal injection was done on the 18th day of pregnancy; the plasma and brains of the mother mice, placentae and the fetuses' brains were dissected following 5, 15, 30, 60, and 120 min of treatment.
Significant incorporation of K027 was found in the placentae and in fetuses' brains relative to its levels in the mothers' plasma and brains. This incorporation warns of a possible adjustment of dose of pyridinium aldoxime antidotes in case of pregnancy.
Further studies with different gestational periods and animal models are warranted.
