Synthesis and evaluation of arylalkoxy- and biarylalkoxy-phenylamide and phenylimidazoles as potent and selective sphingosine-1-phosphate receptor subtype-1 agonists
摘要:
In pursuit of potent and selective sphingosine-1-phosphate receptor agonists, we have utilized previously reported phenylamide and phenylimidazole scaffolds to explore extensive side-chain modi. cations to generate new molecular entities. A number of designed molecules demonstrate good selectivity and excellent in vitro and in vivo potency in both mouse and rat models. Oral administration of the lead molecule 11c (PPI-4667) demonstrated potent and dose-responsive lymphopenia. (c) 2009 Elsevier Ltd. All rights reserved.

thus put forth RTN4 as a potential novel colorectal cancer therapeutic target and reveal a unique druggable hotspot within RTN4 that can be targeted by covalent ligands to impair colorectal cancer pathogenicity. Our results underscore the utility of coupling the screening of fragment-based covalent ligands with isoTOP-ABPP platforms for mining the proteome for novel druggable nodes that can be targeted

analysis. The catalyst exhibited remarkable catalytic activity and chemoselectivity for the reduction of various substituted nitroarenes with sodiumborohydride (NaBH4) as the source of inexpensive hydride in water at room temperature. High turnover frequency and selectivity were observed for the reduction of all tested substrates. Interestingly, the catalyst could be recovered conveniently for multiple
摘要 本研究制备了一种新型的、可生物降解的、环境友好的由 DNA 负载镍纳米粒子组成的催化剂,并通过傅里叶变换红外光谱、高分辨透射电子显微镜、能量色散 X 射线分析、X 射线光电子能谱、紫外可见光谱、电感耦合等离子体发射光谱和元素分析。该催化剂在室温下用硼氢化钠 (NaBH4) 作为廉价的氢化物来源在水中还原各种取代硝基芳烃时表现出显着的催化活性和化学选择性。对于所有测试底物的还原,观察到高周转频率和选择性。有趣的是,该催化剂可以方便地回收用于多次循环反应,具有持续的活性。此外,在反应过程中几乎没有镍物质从催化剂中浸出,证明了本催化方案中真正的异质性。 图文摘要通过 DNA 负载的镍纳米粒子与硼氢化钠实现将各种硝基芳族化合物还原成相应的胺常温下在水中作还原剂。

This invention is in the field of medicinal chemistry. In particular, the invention relates to a new class of small-molecules having a quinazolinedione structure which function as reactive oxygen species (ROS) inducers and inhibitors of mitochondrial activity within cancer cells (e.g., pancreatic cancer cells), and their use as therapeutics for the treatment of cancer (e.g., pancreatic cancer) and other diseases.
modulators that we previously showed to inducepotent growth inhibition in pancreatic ductal adenocarcinoma (PDAC) cell lines. Our lead optimization campaign yielded QD325 as the most potent redox modulator candidate inducing substantial reactive oxygen species (ROS) in PDAC cells. Nascent RNA sequencing following treatments with the QD compounds revealed induction of stress responses in nucleus, endoplasmic
