constitute several FDA-approved drugs for cancer treatment. In this work, a new set of 2-(2-(substituted) hydrazinyl)-4-(1-methyl-1H-benzo[d]imidazol-2-yl) thiazoles 4a-q were designed as epidermal growth factor receptor (EGFR) inhibitors and synthesized using concise synthetic methods. The new target compounds have been evaluated in vitro for their suppression activity against EGFR TK. Compounds 4n, 4h
杂环如噻唑和苯并咪唑被认为是特权结构,因为它们构成了几种FDA批准的用于癌症治疗的药物。在这项工作中,设计了一组新的2-(2-(取代)肼基)-4-(1-甲基-1 H-苯并[ d ]咪唑-2-基)噻唑4a-q作为表皮生长因子受体(EGFR)抑制剂,并使用简明的合成方法合成。已经在体外评估了新的目标化合物对EGFR TK的抑制活性。化合物4n,4h,4i,4a和4d与作为参考药物的厄洛替尼相比,具有显着的效力(IC50,71.67–152.59 nM; IC50厄洛替尼,152.59 nM)。此外,MTT分析表明,化合物4j,4a,4f,4h,4n对人乳腺癌细胞系(MCF-7)产生了最有希望的细胞毒性作用(IC50; 5.96-11-1.91 µM;厄洛替尼IC50; 4.15 µM)。化合物4a作为EGFR TK抑制剂和抗乳腺癌药物显示出有希望的活性。此外,4a诱导凋亡作用,并在G2 / M

Reactions of thiosemicarbazones with 2‐amino‐1,1,2‐ethenetricarbonitrile were reported. The reaction occurred in the amidrazonyl site, and new pyrimidine‐2‐thiones were obtained. The reaction mechanism was discussed. The structure of products was elucidated by MS, IR, and NMR spectra together with elemental analyses. The antitumoractivity was evaluated against one tumor cell line. Using a standard

MCF-7, A-549, and CHO-K1 cell lines, respectively. The CDK4 enzyme assay revealed the significant CDK4 inhibitory activity of compound 2b with IC50 of 0.036 µM. The selectivity of the newly discovered lead compound 2b toward localization in tumor cells was confirmed by a radioiodination biological assay that was done via electrophilic substitution reaction utilizing the oxidative effect of chloramine-t

Abstract The reaction of cobalt, nickel, copper and cadmiumchlorides and bromides with 5-methylfurfural thiosemicarbazone (M5FTSC) leads to the formation of two series of new complexes: [M(M5FTSC)2X2], [M(M5FTSC)X2]. They have been characterized by spectroscopic studies (infrared, 1H NMR, and electronic spectra). The crystalstructures of the free ligand M5FTSC and of the compound [CuCl2(M5FTSC)]
摘要钴,镍,铜和镉的氯化物和溴化物与5-甲基糠醛硫代半碳酰胺(M5FTSC)的反应导致形成两个新的复合物系列:[M(M5FTSC)2X2],[M(M5FTSC)X2]。它们已经通过光谱研究(红外,1 H NMR和电子光谱)进行了表征。游离配体M5FTSC和化合物[CuCl2(M5FTSC)]的晶体结构已通过X射线衍射法确定。对于Co(II),Ni(II)和Cu(II)配合物,中心原子通过硫原子和甲亚胺氮原子配位,而对于Cd(II)配合物,配位原子为硫和呋喃氧原子而不是偶氮甲碱氮。
