Given the requirements of high sensitivity and spatial resolution, the development of new positron emission tomog. (PET) agents is required for PET renog. The objective of this study was to investigate a new fluorine-18 labeled hippurate analog of picolinamide, N-(6-[18F]Fluoropyridin-3-yl)glycine, as a new renal PET agent for evaluating renal function. N-(6-[18F]Fluoropyridin-3-yl)glycine was prepared via a two-step reaction, including the nucleophilic substitution reaction of Br with 18F using Me 2-(6-bromonicotinamido)acetate as a precursor followed the hydrolysis with sodium hydroxide and purification by preparative-HPLC. The in vitro and in vivo stability were determined using HPLC, and the plasma protein binding (PPB) and erythrocyte uptake of N-(6-[18F]Fluoropyridin-3-yl)glycine were determined using blood collected from healthy rats at 5 min post-injection. Biodistribution and dynamic micro-PET/CT imaging studies were conducted in healthy rats. N-(6-[18F]Fluoropyridin-3-yl)glycine demonstrated good stability both in vitro and in vivo. The results of the biodistribution and dynamic micro-PET/CT imaging studies in normal rats indicated that N-(6-[18F]Fluoropyridin-3-yl)glycine was rapidly and exclusively excreted via the renal-urinary pathway. N-(6-[18F]Fluoropyridin-3-yl)glycine is has been shown to be a promising renal PET agent and warrants further evaluation of renal function.

This work aims at evaluating potential direct CO2 conversion processes through systematic screening and process simulation. Fifteen direct routes converting CO2 to carbonates or carbamates, with in situ chem. dehydration using 2-cyanopyridine (2-CP) are focused. The work covers an extensive examination (and supplement) on the phys. properties, selection of promising routes, process simulation, optimization, environmental, and techno-economic evaluation. Firstly, three promising routes were selected, producing di-Me carbonate (DMC), di-Pr carbonate (DPC), and Iso-Pr N-phenylcarbamate (IPPhCM), based on three criteria: azeotropic search, product selectivity and reacting conditions. Next, the corresponding processes were simulated, optimized, heat-integrated, and systematically compared with the previously-proposed di-Et carbonate (DEC) process through environmental and economic anal. From environmental anal., the CO2 emission rate (CO2-e, in kg/kg-product) was 0.067, 0.088, -0.040 and -0.154 for producing DMC, DPC, IPPhCM and DEC, resp. By reducing the excess ratio used for reaction (i.e. 2-CP/alc. or amine/alc.), the CO2-e improved to -0.122, -0.086, and -0.117 for producing DMC, DPC and IPPhCM, resp. Finally, the min. required selling prices (MRSP) at 15% internal rate of return (IRR) were determined, with the unit price of 2-CP, 2-picolinamide (2-PA), and the reactor residence time regarded as uncertainties. The MRSPs for DMC, DPC, IPPhCM and DEC are found in the range of 1.50-4.96, 2.29-4.24, 2.07-4.06 and 1.12-2.81 (all in USD/kg), resp. Future studies exploring the com. availability and the regeneration of 2-CP, and the feasibility of reducing the excess ratio and the reaction residence time are considered helpful.
