?In-loop? [11C]CO2 fixation: Prototype and proof of concept

Carbon-11-labeled carbon dioxide is the most common feedstock for the synthesis of positron emission tomography radiotracers and can be directly used for 11C-carbonylation. Herein, we report the development of an apparatus that takes advantage of ?in-loop? technologies to facilitate robust and reproducible syntheses of 11C-carbonyl-based radiotracers by [11C]CO2-fixation. Our ?in-loop? [11C]CO2-fixation method is simple, efficient, and proceeds smoothly at ambient pressure and temperature. We selected model 11C-carbonyl-labeled carbamates as well as symmetrical and unsymmetrical ureas based on their widespread use in radiotracer design and our clinical research interests for proof of concept. Utility of this method is demonstrated by the synthesis of a reversible radiopharmaceutical for monoamine oxidase B, [11C]SL25.1188, and 2 novel fatty acid amide hydrolase inhibitors. These radiotracers were isolated and formulated (>3.5?GBq; 100?mCi) with radiochemical purities (>99%) and molar radioactivity (?80?GBq/mumol; ?2162?mCi/mumol).

CURABLE URETHANE DIMETHACRYLATES AND DENTAL RESTORATIVE COMPOSITIONS THEREOF

BisGMA is the most widely used resin in dental composites, however, it is being phased out for use due to potential long-term health effects. The present invention relates to a urethane dimethacrylate replacement candidate based on the reaction products of equal molar amounts of 2-hydroxypropylmethacrylate and 2-hydroxyethylmethacrylate with mixed-MDI. This resin is a viscous liquid at room temperature; however, formulations with reactive diluents produce low viscosity liquid with a refractive index comparable to bisGMA formulations, as well as having Young’s modulus comparable to bisGMA formulations. Unlike bisGMA this resin should have no negative health effects.

Nanoscale synthesis and affinity ranking

Most drugs are developed through iterative rounds of chemical synthesis and biochemical testing to optimize the affinity of a particular compound for a protein target of therapeutic interest. This process is challenging because candidate molecules must be selected from a chemical space of more than 1060 drug-like possibilities 1, and a single reaction used to synthesize each molecule has more than 107 plausible permutations of catalysts, ligands, additives and other parameters 2 . The merger of a method for high-throughput chemical synthesis with a biochemical assay would facilitate the exploration of this enormous search space and streamline the hunt for new drugs and chemical probes. Miniaturized high-throughput chemical synthesis 3-7 has enabled rapid evaluation of reaction space, but so far the merger of such syntheses with bioassays has been achieved with only low-density reaction arrays, which analyse only a handful of analogues prepared under a single reaction condition 8-13 . High-density chemical synthesis approaches that have been coupled to bioassays, including on-bead 14, on-surface 15, on-DNA 16 and mass-encoding technologies 17, greatly reduce material requirements, but they require the covalent linkage of substrates to a potentially reactive support, must be performed under high dilution and must operate in a mixture format. These reaction attributes limit the application of transition-metal catalysts, which are easily poisoned by the many functional groups present in a complex mixture, and of transformations for which the kinetics require a high concentration of reactant. Here we couple high-throughput nanomole-scale synthesis with a label-free affinity-selection mass spectrometry bioassay. Each reaction is performed at a 0.1-molar concentration in a discrete well to enable transition-metal catalysis while consuming less than 0.05 milligrams of substrate per reaction. The affinity-selection mass spectrometry bioassay is then used to rank the affinity of the reaction products to target proteins, removing the need for time-intensive reaction purification. This method enables the primary synthesis and testing steps that are critical to the invention of protein inhibitors to be performed rapidly and with minimal consumption of starting materials.
