Synthesis and preclinical evaluation of novel PET probes for P-glycoprotein function and expression
P-glycoprotein (P-gp) is an ATP-dependent efflux pump protecting the body against xenobiotics. A P-gp substrate (7) and an inhibitor (6) were labeled with 11C, resulting in potential tracers of P-gp function and expression. Methods: 6 and 7 were labeled using 11CH3I. 11C-verapamil was prepared as published previously, using 11C-methyl triflate. MicroPET scans (with arterial sampling) and biodistribution studies were performed in rats pretreated with saline, cyclosporin A (CsA, 50 mg/kg), or cold 6 (15 mg/kg). Results: The radiochemical yields of 11C-6 and 11C-7 were approximately 30%with a total synthesis time of 45 min. Cerebral distribution volumes (DV) of 11C-6 (2.35 ¡À 0.11) and 11C-7 (1.86 ¡À 0.15) in saline-treated rats were higher than of 11C-verapamil (0.64 ¡À 0.12). DVs of 11C-7 and 11C-verapamil were significantly increased by CsA (to 5.26¡À0.14 and 5.85¡À0.32, respectively). The DV of 11C-6 was reduced by cold 6 (to 1.65¡À0.03). Its uptakewas also reduced (up to 67%) in several peripheral organs that express P-gp. Conclusions: 11C-7 is a novel tracer of P-gp function with higher baseline uptake than 11C-verapamil. Upregulation of P-gp function in response to treatment (which is hard to detect with 11C-verapamil) may be detectable using 11C-7 and PET. Because 11C-6 shows specific binding in target organs, this compound is the first PET tracer allowing measurement of P-gp expression.
