表观遗传酶现在被靶向治疗导致疾病发病机制的潜在基因表达失调。组蛋白脱乙酰酶(HDAC)在癌症治疗中显示出广泛的潜力,新出现的数据支持其在心血管疾病和中枢神经系统功能障碍背景下的靶向作用。开发用于非侵入性成像的分子试剂以阐明HDAC在人体中的分布和功能作用,将加速该领域的医学研究和药物发现。在此,我们描述了HDAC成像剂[11 C]6的合成和验证。我们的成像结果表明,该探针具有高特异性,良好的选择性,以及适当的动力学和分布成像HDAC在脑,心脏,肾脏,胰腺和脾脏。我们的研究结果支持[11 C]6用于人类表观遗传成像的翻译潜力。
Epigenetic enzymes are now targeted to treat the underlying gene expression dysregulation that contribute to disease pathogenesis. Histone deacetylases (HDACs) have shown broad potential in treatments against cancer and emerging data supports their targeting in the context of cardiovascular disease and central nervous system dysfunction. Development of a molecular agent for non-invasive imaging to elucidate the distribution and functional roles of HDACs in humans will accelerate medical research and drug discovery in this domain. Herein, we describe the synthesis and validation of an HDAC imaging agent, [11C]6. Our imaging results demonstrate that this probe has high specificity, good selectivity, and appropriate kinetics and distribution for imaging HDACs in the brain, heart, kidney, pancreas, and spleen. Our findings support the translational potential for [11C]6 for human epigenetic imaging.
