Novel tricyclic inhibitors of IKK2: Discovery and SAR leading to the identification of 2-methoxy-N-((6-(1-methyl-4-(methylamino)-1,6-dihydroimidazo[4,5-d]pyrrolo[2,3-b]pyridin-7-yl)pyridin-2-yl)methyl)acetamide (BMS-066)
摘要:
The synthesis, structure-activity relationships (SAR), and biological results of pyridyl-substituted azaindole based tricyclic inhibitors of IKK2 are described. Compound 4m demonstrated potent in vitro potency, acceptable pharmacokinetic and physicochemical properties, and efficacy when dosed orally in a mouse model of inflammatory bowel disease.

report on the design, synthesis, and operation of a bimetallic molecular biped on a three-foothold track. The "walker" features a palladium(II) complex "foot" that can be selectively stepped between 4-dimethylaminopyridine and pyridine ligand sites on the track via reversible protonation while the walker remains attached to the track throughout by means of a kinetically inert platinum(II) complex foot. The
我们报告了双金属分子双足动物在三足轨道上的设计、合成和操作。“助行器”具有钯 (II) 复合“脚”,可以通过可逆质子化选择性地在轨道上的 4-二甲氨基吡啶和吡啶配体位点之间移动,而助行器通过动力学惰性的铂始终保持附着在轨道上( II) 复足。三个配体结合位点的取代模式,连同金属-配体配位键的动力学稳定性,为两个位置异构体提供了高度的亚稳定性,这意味着改变轨道的化学状态不会自动引发步入没有额外的刺激(在配位溶剂存在下加热)。

spectrum. The polycyclic core is obtained from readily available amides via a chemoselective process involving Tf2O-mediated amide cyclodehydration, followed by intramolecular C–H arylation. Additionally, these fluorescent heterocycles are easily functionalized using electrophilic reagents, enabling divergent access to varied substitution. The effects of said substitution on the compounds’ photophysical
在这里,我们报告发现苯并[ a ]咪唑并[2,1,5- c,d ]吲哚嗪基序的发现,其可调谐发射涵盖了大部分可见光谱。多环核心是通过涉及Tf 2的化学选择过程从容易获得的酰胺中获得的O介导的酰胺环脱水,然后进行分子内C–H芳基化。此外,使用亲电子试剂可以轻松地将这些荧光杂环官能化,从而实现不同取代的多样化途径。通过密度泛函理论计算合理化了所述取代对化合物光物理性质的影响。对于某些化合物,发射波长与取代基的哈米特常数直接相关。易于引入的非共轭反应性官能团可在不修饰发射特性的情况下标记生物分子。这项工作为合成新的中等亮度的荧光染料提供了一个简单的平台,这些染料以其化学稳定性,可预测性和异常高的激发-发射差异而著称。

Imidazo[1,5-a]azines are synthesized in moderate to excellent yields using a mild cyclodehydration/aromatization reaction triggered by the use of triflic anhydride (Tf2O) and 2-methoxypyridine (2-MeOPyr). Various substitution patterns and functional groups were found to be compatible under the optimized conditions. In addition, a 5-bromo-3-aryl derivative was also shown to be active in a Sonogashira
