Route scouting and optimization of a potent sulfoximine-based inverse agonist of RORγt
摘要:
During our research looking for novel inverse agonists of ROR gamma t, we identified a potent sulfoximine-based modulator as one of our pre-clinical candidates for the topical treatment for psoriasis. Herein, we describe the various routes we evaluated during the lead generation and optimization phases and the final route chosen for scale-up to deliver the first 100 g of API.

Borrowinghydrogen from alcohols, storing it on a catalyst and subsequent transfer of the hydrogen from the catalyst to an in situ generated imine is the hallmark of a transition metal mediated catalytic N-alkylation of amines. However, such a borrowinghydrogen mechanism with a transition metal free catalytic system which stores hydrogen molecules in the catalyst backbone is yet to be established
从醇中借用氢气,将其储存在催化剂上,然后将氢气从催化剂转移到原位生成的亚胺,这是过渡金属介导的胺催化N-烷基化的标志。然而,这种在催化剂主链中储存氢分子的无过渡金属催化系统的借氢机制尚未建立。在此,我们证明苯酚基配体可以模仿过渡金属在储存和转移氢分子中的作用,从而导致借氢介导的醇类苯胺烷基化,包括广泛的底物范围。通过各种光谱技术、氘标记实验和 DFT 研究表征几种中间体,对机制途径进行了仔细检查,得出的结论是,基于苯酚基的主链通过脱芳构化过程依次添加 H + 、 H˙ 和一个电子,随后将其用作还原剂。相当于催化方式中的C-N双键。

Benzenesulfonamide derivatives of formula (I), the pharmaceutically acceptable addition salts thereof, the hydrates and/or solvates thereof, and the use of same as inverse agonist of retinoid-related orphan receptor gamma (RORγt) are described. A pharmaceutical composition including such compounds, as well as the use thereof for the topical and/or oral treatment of RORγt receptor-medicated inflammatory diseases, in particular acne, psoriasis and/or atopic dermatitis are also described.

These efforts culminated in the discovery of N‐(2,4‐dimethylphenyl)‐N‐isobutyl‐2‐oxo‐1‐[(tetrahydro‐2H‐pyran‐4‐yl)methyl]‐2,3‐dihydro‐1H‐benzo[d]imidazole‐5‐sulfonamide (CD12681), a potent inverse agonist with in vivo activity in an IL‐23‐induced mouse skin inflammation model.
视黄酸受体相关的孤儿受体RORγ可能对多种自身免疫性疾病有潜在影响,已成为制药行业的抢手目标。本文描述了鉴定与局部应用治疗皮肤疾病相容的有效RORγ反向激动剂的努力。这些努力最终导致发现了N-(2,4-二甲基苯基)-N-异丁基-2-氧代-1-[[(四氢-2 H-吡喃-4-基)甲基] -2,3-二氢-1 H-苯并[ d ]咪唑-5-磺酰胺(CD12681),一种有效的反向激动剂,在IL-23诱导的小鼠皮肤炎症模型中具有体内活性。
