  Design and SAR of Novel Potassium Channel Openers Targeted for Urge Urinary Incontinence. 2. Selective and Potent Benzylamino Cyclobutenediones

  摘要：

  A novel series of benzylamine, potassium channel openers (KCOs) is presented as part of our program toward designing new, bladder-selective compounds for the treatment of urge urinary incontinence (UUI). We have found that the in vitro potency of (R)-4-[3,4-dioxo-2-(1,2,2-trimethyl-propylamino)-cyclobut-1-enylamino]3-ethyl-benzonitrile 1 in the relaxation of precontracted rat detrusor strips can also be obtained with cyanobenzylamine derivative 4 (IC50 = 0.29 mu M) (Figure 3). Addition of a 2-Cl substituted benzylamine moiety and changing the alkylamino substituent of 4 to a t-Bu amine gives 31 (IC50 = 0.14 mu M)-a compound with similar in vitro potency as 4 as well as relaxant activity on bladder smooth muscle in vivo when administered orally (31, ED50 = 3 mg/kg) in a rodent model of bladder instability. Further modifications, particularly the replacement of the t-Bu amino substituent with a tert-amylamine, gave a similarly active compound 60 (IC50 = 0.10 mu M) which shows excellent in vivo efficacy (ED50 = 0.6 mg/kg). Moreover, 60, 3-(2,4-dichloro-6-methyl-benzylamino)-4- 1,1-dimethylpropylamino)-cyclobut-3-ene-1,2-dione (WAY-151616), shows excellent tissue selectivity for bladder K channels over arterial tissue (60, MAP ED20 = 100 mg/kg; selectivity: MAP ED20/ bladder ED50 = 166). Other manipulations of the benzylamino cyclobutenediones, acylation of the benzylamine, conversion of the benzylamine substituent to a benzamide, homologation of the benzylamine to a phenethylamine, and incorporation of a methyl group at the benzyl carbon, all led to substantial loss of in vitro activity, although some in vivo activity was maintained in the acylated analogues. Compound 60 represents an attractive candidate for development in the treatment of UUI.

  could have been introduced in BAF312 without modifying its structure, they do not have decay kinetics compatible with the time required for observing the drug′s organ distribution in patients. In contrast, the SPECT radioisotope 123I has a longer half‐life and would suit this purpose. Herein we report the identification of an iodinated derivative of BAF312, (E)‐1‐(4‐(1‐(((4‐cyclohexyl‐3‐iodobenzyl)ox

  BAF312（siponimod）是一种鞘氨醇-1-磷酸（S1P）受体调节剂，在临床开发中用于治疗多发性硬化症，比其前体FTY720（芬戈莫德）具有更快的器官/组织分布和清除动力学。我们的目标是开发一种示踪剂，以更好地量化BAF312在人脑中的渗透，并有可能被标记为正电子发射断层扫描（PET）或单光子发射计算机断层扫描（SPECT）。尽管可以在不更改其结构的情况下将PET放射性同位素11 C和18 F引入BAF312中，但是它们的衰变动力学与观察患者体内器官分布所需的时间不兼容。相比之下，SPECT放射性同位素123我的半衰期更长，适合这个目的。在此我们报告了BAF312碘化衍生物的鉴定，（E）-1-（4-（1-（（（（4-环己基-3-碘代苄基氧基）亚氨基）乙基）-2-乙基苄基）氮杂环丁烷-3-羧酸（18，MS565），作为SPECT示踪剂候选物，具有与原始分子相似的亲和力，S1P受体选择
