  Discovery of TD-8954, a clinical stage 5-HT4 receptor agonist with gastrointestinal prokinetic properties

  摘要：

  The discovery of a series of 5-HT4 receptor agonists based on a novel 2-alkylbenzimidazole aromatic core is described. Optimization of the 2-substituent of the benzimidazole ring led to a series of agonists with subnanomolar binding affinity and moderate-to-high intrinsic activity relative to that of 5-HT. Consistent with our previously described multivalent design approach to this target, subsequent optimization of the linker and secondary binding group regions of the series afforded compound 18 (TD-8954), a potent and selective 5-HT4 receptor agonist in vitro with demonstrated prokinetic activity in multiple species.

  Compounds of structural formula (I) are modulators of the androgen receptor (AR) in a tissue selective manner. They are useful as agonists of the androgen receptor in bone and/or muscle tissue while antagonizing the AR in the prostate of a male patient or in the uterus of a female patient. These compounds are therefore useful in the enhancement of weakened muscle tone and the treatment of conditions caused by androgen deficiency or which can be ameliorated by androgen administration, including osteoporosis, osteopenia, glucocorticoid-induced osteoporosis, periodontal disease, bone fracture, bone damage following bone reconstructive surgery, sarcopenia, frailty, aging skin, male hypogonadism, postmenopausal symptoms in women, atherosclerosis, hypercholesterolemia, hyperlipidemia, obesity, aplastic anemia and other hematopoietic disorders, inflammatory arthritis and joint repair, HIV-wasting, prostate cancer, cancer cachexia, Alzheimer's disease, muscular dystrophies, cognitive impairment, decreased libido, premature ovarian failure, and autoimmune disease, alone or in combination with other active agents.

  结构式（I）的化合物以组织选择性方式调节雄激素受体（AR）。它们可作为雄激素受体在骨骼和/或肌肉组织中的激动剂，同时在男性患者的前列腺或女性患者的子宫中对抗雄激素受体。因此，这些化合物在增强肌肉张力和治疗由雄激素缺乏引起或可以通过雄激素治疗改善的疾病方面具有用途，包括骨质疏松症、骨质疏松症、糖皮质激素诱导的骨质疏松症、牙周病、骨折、骨重建手术后的骨损伤、肌肉减少症、虚弱、老化皮肤、男性睾丸功能减退、女性绝经后症状、动脉粥样硬化、高胆固醇血症、高脂血症、肥胖、再生障碍性贫血和其他造血系统疾病、炎症性关节炎和关节修复、艾滋病消耗综合征、前列腺癌、癌症消耗综合征、阿尔茨海默病、肌肉萎缩症、认知障碍、性欲减退、卵巢早衰和自身免疫疾病等疾病的治疗，可单独使用或与其他活性药物联合使用。
