Dermatologic disorders such as atopic dermatitis arise from genetic and environmental causes and are complex and multifactorial in nature. Among possible risk factors, aberrant immunological reactions are one of the leading etiologies. Immunosuppressive agents including topical steroids are common treatments for these disorders. Despite their reliability in clinical settings, topical steroids display side effects, typified by skin thinning. Accordingly, there is a need for alternate effective and well-tolerated therapies. As part of our efforts to investigate new immunomodulators, we have developed a series of JAK inhibitors, which incorporate novel three-dimensional spiro motifs and unexpectedly possess both excellent physicochemical properties and antidermatitis efficacy in the animal models. One of these compounds, JTE-052 (ent-60), also known as delgocitinib, has been shown to be effective and well-tolerated in human clinical trials and has recently been approved in Japan for the treatment of atopic dermatitis as the first drug among Janus kinase inhibitors.

带有高度三维螺旋支架的Janus激酶抑制剂的发现：JTE-052（Delgocitinib）作为新型皮肤病治疗炎症性皮肤病的药物。

诸如特应性皮炎的皮肤疾病源于遗传和环境原因，并且本质上是复杂的和多因素的。在可能的危险因素中，异常的免疫反应是主要病因之一。包括局部类固醇在内的免疫抑制剂是这些疾病的常见治疗方法。尽管它们在临床环境中具有可靠性，但局部类固醇仍具有副作用，典型表现为皮肤变薄。因此，需要替代的有效和良好耐受的疗法。作为研究新的免疫调节剂的努力的一部分，我们开发了一系列JAK抑制剂，这些抑制剂结合了新颖的三维螺旋基序，并且出乎意料地在动物模型中拥有出色的理化特性和抗皮炎功效。其中一种化合物JTE-052（ent - 60，也称为delgocitinib，在人体临床试验中已显示出有效且耐受性良好，最近在日本被批准用于治疗特应性皮炎，是Janus激酶抑制剂中的第一种药物。
