摘要:
This invention generally relates to pyrazolo pyrimidine derivatives useful as, inter alia, inhibitors of short chain dehydrogenase/reductase (SDR) family of NAD(P)(H) dependent oxido-reductases. More specifically, the invention relates to pyrazolo pyrimidine derivatives, including derivatives and analogs of SDR inhibitors, pharmaceutical compositions containing derivatives and analogs of SDR inhibitors, methods of making derivatives and analogs of SDR inhibitors and methods of use thereof.
摘要:
Provided herein are methods of detecting anions in solution. In particular, the methods can be used to detect trace anions in solution. For example, the anions can be present in an amount of between about 500 femtomoles to about 10 millimoles.

This disclosure relates to compounds, reagents, and methods useful in the synthesis of aryl fluorides, for example, in the preparation of 18F labeled radiotracers. For example, this disclosure provides universal “locked” aryl substituents that result in StereoElectronic Control of Unidirectional Reductive Elimination (SECURE) from diaryliodonium salts. The reagents and methods provided herein may be used to access a broad range of compounds, including aromatic compounds, heteroaromatic compounds, amino acids, nucleotides, and synthetic compounds.
摘要:
Strapped porphyrins and electron-deficient porphyrins are provided, as well as processes and intermediates for their preparation. In certain embodiments, such compounds are prepared by nucleophilic displacement of leaving groups from methylpyrroles. In other embodiments, such compounds are prepared by condensing pyrrole derivatives and removing water thus formed from the resulting reaction mixture.
摘要:
Electron-deficient porphyrins are provided, as well as processes and intermediates for their preparation. In preferred embodiments, the electron-deficient porphyrins are prepared by condensing pyrrole derivatives and removing water thus formed from the resulting reaction mixture.

摘要:
The present invention is directed to a method for preparing an anhydrous 18F-radiolabeled fluorinating agent by a nucleophilic reaction of a hydrated 18F-radiolabeled fluoride ion source with an unsaturated carrier compound; treating the 18F-radiolabeled carrier compound to produce a non-aqueous mixture of the 18F-radiolabeled carrier compound in a solvent; and reacting the 18F-radiolabeled carrier compound with a nucleophilic composition in a nucleophilic reaction to produce an anhydrous 18F-radiolabeled fluorinating agent. The present invention is also directed to an anhydrous 18F-radiolabeled fluorinating agent comprising the formula [QnM]x+(18F−)x. Additionally, the present invention is directed to an 18F-radiolabeled fluorinated radiopharmaceutical or an 18F-radiolabeled fluorinated radiotracer prepared by reacting the anhydrous 18F-radiolabeled fluorinating agent with a drug intermediate. The present invention is further directed to methods for treating a disease or imaging a subject using an 18F-radiolabeled fluorinated radiopharmaceutical or an 18F-radiolabeled fluorinated radiotracer.
