EGFR的过表达通常与晚期疾病和不良预后有关。在某些癌症中,Src与EGFR协同作用以促进增殖,存活,侵袭和转移。针对EGFR和Src的双靶标药物的开发具有针对这些癌症的治疗优势。基于分子对接和我们先前的研究,我们合理地设计了一系列新的氮杂ac啶衍生物作为有效的EGFR和Src双重抑制剂。大多数合成的氮杂ac啶对K562和A549细胞显示出良好的抗增殖活性。代表性化合物13b对K562和A549细胞显示nM IC 50值,并在10μM下以33.53%的抑制率抑制EGFR,在1μM下以72.12%的抑制率抑制Src。此外,复合13b可以抑制EGFR,p-EGFR,Src和p-Src的表达。此外,13b有效抑制肿瘤细胞的侵袭并诱导癌细胞凋亡。我们的研究表明,可将氮杂ac啶支架开发为新型的多靶点激酶抑制剂,用于癌症治疗。
Chiral phosphoramidite–olefin hybrid ligands were found to be effective in the iridium-catalyzed asymmetric alkylation of N-arylbenzamides with vinyl ethers. The reaction is catalyzed by a hydroxoiridium catalyst coordinated with the hybrid ligand to give the corresponding products in high yields with high branch selectivity and enantioselectivity.

[10% Cu(NO3)(2)3H(2)O] nitration of anilides was developed by using TBN (tert-butyl nitrite) as a nitrating reagent to give the corresponding nitro-substituted aromatic products in good to excellent yields. The use of TBN also led to the selective nitration of acrylamides at room temperature to afford only the (E) isomer of the nitration product. A series of anilides and acrylamides with a broad array

oquinazoline derivatives bearing diarylamide moiety were designed, synthesized and evaluated as potent inhibitors of VEGFR-2kinase. Their in vitro antiproliferation activities against two human cancer cell lines Hep-G2 and MCF-7 have also been determined. Among them, compound 14b exhibited the most potent inhibitory activity against VEGFR-2 with IC50 value of 0.016 ± 0.002 µM and it showed the most

Quinoline derivatives, particularly 4-anilinoquinoline derivatives, are provided. Such quinoline derivatives can be used for modulation of DNA methylation, such as effective inhibition of methylation of cytosine at the C-5 position, for example via selective inhibition of DNA methyltransferase DNMT1. Methods for synthesizing numerous 4-anilinoquinoline derivatives and for modulating DNA methylation are provided. Also provided are methods for formulating and administering these compounds or compositions to treat conditions such as cancer and hematological disorders.
