The subject of the invention covers the substituted derivatives of dicarboximides represented by the general formula 1:
possibly in the form of pharmaceutically acceptable salts, wherein R means the alkyl group C1-C6, optionally, the alkyl group is substituted with -OH group or amine group, selected from group containing -NH-R1 group or the group with formula 2 or 3, where R1, R2, R3 are the same or different and cover the alkyl group C1-C3 and R4 means -CH2- or -O-
and the application of these compounds, or in combination with other drugs.
New Succinimides with Potent Anticancer Activity: Synthesis, Activation of Stress Signaling Pathways and Characterization of Apoptosis in Leukemia and Cervical Cancer Cells
immunomodulatory activities, a series of 26 new derivatives were designed and synthesized by the Diels–Alderreaction between appropriate diene and maleimide or hydroxymaleimide moieties. The resulting imides were functionalized with alkanolamine or alkylamine side chains and subsequently converted to their hydrochlorides. The structures of the obtained compounds were confirmed by 1H and 13C NMR and by ESI MS
基于先前确定的具有显着的抗癌和免疫调节活性的二羧酰亚胺,通过适当的二烯与马来酰亚胺或羟基马来酰亚胺基团之间的狄尔斯-阿尔德反应设计并合成了一系列26种新衍生物。所得酰亚胺用链烷醇胺或烷基胺侧链官能化,然后转化为它们的盐酸盐。所得化合物的结构通过1 H和13 C NMR以及ESI MS光谱分析确认。在人白血病(K562,MOLT4),宫颈癌(HeLa)和正常内皮细胞(HUVEC)中评估了它们的细胞毒性。大多数衍生物在K562细胞中表现出高至中等的细胞毒性并诱导细胞凋亡。芯片基因谱分析表明参与受体介导的和线粒体细胞死亡途径的凋亡基因的上调,以及参与NF-kB信号传导的抗凋亡基因的上调。选定的二甲酰亚胺可激活白血病细胞中的JNK和p38激酶,表明MAPKs可能参与细胞凋亡的调控。如通过质粒DNA切割保护分析所评估的,测试的二羧酰亚胺与DNA结合。所选的二甲酰亚胺提供了新的支架,可以作为抗癌药物进行进一步开发。
New Thalidomide-Resembling Dicarboximides Target ABC50 Protein and Show Antileukemic and Immunomodulatory Activities
activation of receptor and mitochondrial apoptotic pathways and increased the expression of proapoptotic genes (BAX, NOXA, HTRA2, TNFRSF10B, ESRRBL1). Selected dicarboximides displayed immunomodulatory activity and downregulated IKZF1 and IKZF3 transcription factors in K562 and MOLT-4 leukemia cells. ATP-binding cassette protein 50 (ABC50) was identified as a target for dicarboximides. Cancer cells with
