    摘要: An efficient, regiocontrolled approach to the synthesis of 8-fluoropurines by direct fluorination of purines with dilute elemental fluorine, or acetyl hypofluorite, is provided. In a preferred embodiment, a purine compound is dissolved in a polar solvent and reacted with a dilute mixture of F2 in He or other inert gas.

    摘要: Provided herein are [18F]-labeled compounds having a chemical structure: R1 is 18F, 1-piperazinyl-4-CH2CH2—18F or 1-piperazinyl-4-CH2CH2OCH2CH2—18F, R2 is CH3 or 18F and R3 is Cl or 18F, such that only one of R1, R2 and R3 comprise an 18F. Also provided are methods for in vivo imaging using the [18F]-labeled compounds, particularly methods of imaging utilizing positron emission tomography. These methods are effective for diagnosing a pathophysiological condition susceptible to treatment with kinase inhibitor(s) in a subject, or for determining whether a cancer in a subject that is susceptible to being treated with a kinase inhibitor has developed resistance or increased sensitivity to the same and for maximizing tumor response to akinase inhibitor with minimal toxicity to the subject.
