Novel yellow azo dyes were synthesized by diazotization of aromatic amines followed by coupling with 2-morpholin-4-yl-1,3-thiazol-4(5H)-one and fully characterized. The geometries of the synthesized dyes for azo and hydrazone tautomeric forms were optimized using B3LYP, CAM-B3LYP and M06 functional and 6-31G(d) and 6-311++G (d,p) basis sets, also their electronic excitation properties were evaluated

A series of new imidazo[1,2-a]pyridinelinked with thiazole/thiophene motif through a keto spacer were synthesized and tested for their cytotoxic potential against three human cancer cell lines including A549, HeLa and U87-MG using MTT assay. Compounds A2, A3, A4, C1 and C2 showed cytotoxicity against all the three cell lines. The selectivity index for compound A4 for A549 and HeLa cells was comparable
合成了一系列新的通过酮间隔基与噻唑/噻吩基团连接的咪唑并[1,2- a ]吡啶,并使用MTT法测试了它们对三种人类癌细胞系(包括A549,HeLa和U87-MG)的细胞毒性潜力。化合物A2,A3,A4,C1和C2对所有三种细胞系均显示出细胞毒性。化合物A4对A549和HeLa细胞的选择性指数与阿霉素相当。在合成的化合物中,B5表现出对NF-κB活性的最大抑制作用,这是通过NF-κB报告基因分析确定的(IC 50 = 6.5±0.6 µM)。用埃洛替尼和吉非替尼以及化合物A4和B5处理NCI-H23细胞(EGFR过表达,KRAS G12V突变体)表明联合治疗具有协同作用和加成作用。

Two novel coumarin thiazole hybrid dyes (E)-2-(3-(2-(4-(4-hydroxy-2-oxo-2H-chromen-3-yl)-2-morpholinothiazol-5-yl)vinyl)-5,5-dimethylcyclohex-2-en-1-ylidene)malononitrile (CSI) and (E)-2-(3-(2-(4-(4-methoxy-2-oxo-2H-chromen-3-yl)-2-morpholinothiazol-5-yl)vinyl)-5,5-dimethylcyclohex-2-en-1-ylidene)malononitrile (MeOCSI) were synthesized. CSI exhibits near infrared emission with very large Stokes shift

grossularia ). It has a five-membered ring, namely, it is a heterocycle thiadiazole, which is found rarely in natural sources . Following its biological activities, novel analogs have been investigated recently. Synthesis of the analogs for this study is realized with uncommon thiazole closure, including methylene-carbonyl condensation. Structures are elucidated by NMR ( 1 , 13 C) and HRMS spectrums. As
