尽管付出了很大努力,但我们对许多大脑疾病的了解仍然非常有限。在过去的十年里,表观遗传失调一直是确定精神疾病的原因和潜在治疗方法的为数不多的线索之一。一种新的正电子发射断层扫描放射性示踪剂[11C]Martinostat使活体受试者的组蛋白脱乙酰酶的研究成为可能。[11C]Martinostat的一个独特属性是其深刻的大脑透视性,这是一个故意设计的具有挑战性的功能。为了了解马替诺他汀脑高摄取的决定因素,对一系列化合物在啮齿动物和非人类灵长类动物身上进行了评估。这项研究揭示了大脑摄取的主要结构性贡献因素,以及一种更具临床相关性的氟化HDAC放射性示踪剂,其行为与Martinostat相似,但半衰期更长。
Despite major efforts, our knowledge about many brain diseases remains remarkably limited. Epigenetic dysregulation has been one of the few leads toward identifying the causes and potential treatments of psychiatric disease over the past decade. A new positron emission tomography radiotracer, [11C]Martinostat, has enabled the study of histone deacetylase in living human subjects. A unique property of [11C]Martinostat is its profound brain penetrance, a feature that is challenging to engineer intentionally. In order to understand determining factors for the high brain-uptake of Martinostat, a series of compounds was evaluated in rodents and non-human primates. The study revealed the major structural contributors to brain uptake, as well as a more clinically relevant fluorinated HDAC radiotracer with comparable behavior to Martinostat, yet longer half-life.
