Conventional and microwave-assisted solvent-free synthesis of fused [1,2,5]thiadiazolo[3,4-b]quinoxaline-2,2-dioxide derivatives
摘要:
A simple, highly efficient and environmentally friendly procedure for the condensation of $o$-phenylenediamine with 2,5-dialkyl-1,2,5-thiadiazolidine-3,4-dione-1,1-dioxides via two microwave-assisted reactions is described. These compounds were also prepared via a conventional heating method to provide a comparison with the microwave-assisted irradiation reaction protocol. The structures of the synthesized compounds were confirmed using infrared, H-1 NMR and mass spectral analysis.
Peptides have important biological functions. However, peptides' susceptibility to proteolysis is a big hurdle to their application. We demonstrated, for the first time, that poly(2-oxazoline) can work as functionalmimics of peptides. Using host defense peptide as a model, we showed poly(2-oxazoline) based glycine pseudopeptides can mimic host defense peptide and have potent in vitro and in vivo activities

Brequinar, a potent dihydroorotate dehydrogenase (DHODH) inhibitor, has been evaluated in multiple clinical trials as a potential treatment for cancer. To further understand brequinar‐based DHODH inhibition and DHODH′s therapeutic relevance in cancer, we have developed novel brequinar‐based probes. We disclose a 16‐step convergentsynthesis of the first brequinar‐PROTAC and a four‐step approach towards

discovery. α‐Helix mediated PPIs may be amenable to modulation using generic chemotypes, termed “proteomimetics”, which can be assembled in a modular manner to reproduce the vectoral presentation of key side chains found on a helical motif from one partner within the PPI. In this work, it is demonstrated that by using a library of N‐alkylated aromatic oligoamide helixmimetics, potent helixmimetics which
抑制蛋白质-蛋白质相互作用 (PPI) 是化学生物学和药物发现的主要挑战。α-螺旋介导的 PPI 可能适合使用称为“蛋白质模拟物”的通用化学型进行调节,该化学型可以以模块化方式组装,以重现 PPI 内一个伙伴在螺旋基序上发现的关键侧链的矢量呈现。在这项工作中,证明通过使用 N-烷基化芳族寡酰胺螺旋模拟物库,可以识别在细胞环境中重现其生物物理结合选择性的有效螺旋模拟物。
