Racemic [¹⁸F]FBFP ([¹⁸F]1) proved to be a potent σ1 receptor radiotracer with superior imaging properties. The pure enantiomers of unlabeled compounds (S)- and (R)-1 and the corresponding iodonium ylide precursors were synthesized and characterized. The two enantiomers (S)-1 and (R)-1 exhibited comparable high affinity for σ1 receptors and selectivity over σ2 receptors. The Ca²⁺ fluorescence assay indicated that (R)-1 behaved as an antagonist and (S)-1 as an agonist for σ1 receptors. The ¹⁸F-labeled enantiomers (S)- and (R)-[18F]1 were obtained in > 99% enantiomeric purity from the corresponding enantiopure iodonium ylide precursors with radiochem. yield of 24.4% ± 2.6% and molar activity of 86-214 GBq/μmol. In ICR mice both (S)- and (R)-[18F]1 displayed comparable high brain uptake, brain-to-blood ratio, in vivo stability and binding specificity in the brain and peripheral organs. In micro-positron emission tomog. (PET) imaging studies in rats, (S)-[¹⁸F]1 exhibited faster clearance from the brain than (R)-[¹⁸F]1, indicating different brain kinetics of the two enantiomers. Both (S)- and (R)-[¹⁸F]1 warrant further evaluation in primates to translate a single enantiomer with more suitable kinetics for imaging the σ1 receptors in humans.

Wang, Xiang-Zhao;Xie, Dong-Mei;Zhao, Xiao-Li;Li, Yi-Dong;Zeng, Jian-Bing research published 《 Sustainable, Malleable, and Recyclable Castor Oil-Derived Poly(urethane urea) Networks with Tunable Mechanical Properties and Shape Memory Performance Based on Dynamic Piperazine-Urea Bonds》, the research content is summarized as follows. Castor oil (CO)-derived polyurethanes (PUs), denoted CPUs, are drastically limited because they cannot be reprocessed, reshaped, or recycled and because they show low strength, poor toughness, and insufficient functionality due to their permanently crosslinked structure with a high crosslink d. and a soft backbone. Herein, we developed novel reversible piperazine-urea bonds (PaUBs) from inexpensive piperazines and isocyanates and incorporated the PaUBs into CPUs to fabricate sustainable and reprocessable poly(urethane urea) covalent adaptable networks (CANs). We synthesized the CANs from CO, N-(2-hydroxyethyl) piperazine (HEP), and 4-methylenedicyclohexyl diisocyanate (HMDI) via a catalyst- and solvent-free approach. The CANs showed variable tensile behavior over a wide range from a soft elastomer to tough and hard plastics. They also exhibited excellent malleability, stable reprocessability, and multiple recyclability, in which their original properties were recovered after several thermal recycling or remolding cycles. The CANs possessed excellent shape memory performance and reconfigurability, allowing them to be reprocessed into various complex shapes without using a mold. The advanced sustainable CANs based on dynamic PaUBs have great potential application as alternatives to traditional fossil-derived elastomers and plastics.
