Proposed scheme for the fate of PZ-DHA upon intraperitoneal administration into Balb/c female mice. Absorption of intraperitoneally administered PZ-DHA via ① superior mesenteric vein and ② inferior mesenteric vein; ③ Phase II metabolism of PZ-DHA in the liver; ④ Biliary secretion and entero-hepatic circulation of PZ-DHA and its metabolites; Distribution of PZ-DHA and its metabolites via ⑤ inferior vena cava, ⑥ left and right carotid arteries, ⑦ bronchial arteries branched from the descending aorta; ⑧ hepatic artery branched from descending aorta, ⑨ splenic artery, and ⑩ renal arteries branched from descending aorta; ⑪ PZ-DHA may be excreted via kidneys. Solid-lined arrows (→) indicate confirmed processes and dashed-line arrows (⇢) indicate suggested potential processes, which need to be confirmed in future studies. BBB blood brain barrier; METs methyltransferases; UGTs UDP-glucuronosyltransferase; SULTs sulphotransferases.
