Ligustrazine Derivatives. Part 6: Design, Synthesis and Evaluation of Novel Ligustrazinyl Acylguanidine Derivatives as Potential Cardiovascular Agents
摘要:
A series of novel Ligustrazinyl acylguanidines was designed, synthesized and evaluated for their protective effect on injured vascular endothelial cell (ECV-304). The preliminary results demonstrated that some compounds possessed more potent activities than that of Ligustrazine in stimulating replication of the injured endothelial cell. Among the active compounds, compounds 8b, 8f and 8l displayed remarkable antioxidative activity with low EC50 values of 0.097, 0.059 and 0.094 mM, respectively. Structure-activity relationships were briefly discussed.

The present invention relates to guanidine compounds for inhibiting mitochondrial oxidative phosphorylation (OXPHOS) and use thereof. More specifically, the present invention relates to a pharmaceutical composition for preventing or treating a OXPHOS-related disease, particularly cancer by inhibiting mitochondrial oxidative phosphorylation and reprogramming cellular metabolism.
design and synthesis of a library of thioxanthones as potentialeffluxpump inhibitors are described. The thioxanthone derivatives were investigated for their antibacterial activity and inhibition of effluxpumps, biofilm formation, and quorum-sensing. The compounds were also studied for their potential to interact with P-glycoprotein (P-gp, ABCB1), an effluxpump present in mammalian cells, and for

unexpectedly, four tetracyclic thioxanthenes with a quinazoline–chromene scaffold were obtained. These compounds were studied for their human tumor cell growth inhibition activity, in the cell lines A375-C5, MCF-7 and NCI-H460. Photophysical studies were also performed. Two of the compounds displayed GI50 values below 10 µM for the three tested cell lines, and structure–activity relationship studies were established
硫杂蒽酮是天然存在的氧杂蒽酮的生物等排体。它们被描述为具有多种活性,包括抗肿瘤。因此,人们继续合成噻吨酮库,但出人意料的是,获得了四个带有喹唑啉-色烯支架的四环噻吨酮。研究了这些化合物在细胞系 A375-C5、MCF-7 和 NCI-H460 中的人肿瘤细胞生长抑制活性。还进行了光物理研究。其中两种化合物显示出 GI 50三个测试细胞系的值低于 10 µM,并建立了结构-活性关系研究。三种化合物呈现出相似的吸收和发射波长,这是具有推拉特性的染料的特征。两种化合物的结构通过 X 射线晶体学进行了阐明。两种四环噻吨作为命中化合物出现。通过荧光显微镜和流式细胞术分析,这两种化合物之一在绿色通道中作为明亮的荧光染料在细胞内积累,使其成为有希望的治疗诊断癌症药物候选者。

Rational Design of a Novel Class of Human ClpP Agonists through a Ring-Opening Strategy with Enhanced Antileukemia Activity
agonist imipridone ONC201. Here, a novel class of HsClpP agonists is designed and synthesized using a ring-opening strategy based on the lead compound 1 reported in our previous study. Among these novel scaffold agonists, compound 7k exhibited remarkably enhanced proteolytic activity of HsClpP (EC50 = 0.79 ± 0.03 μM) and antitumor activity in vitro (IC50 = 0.038 ± 0.003 μM). Moreover, the intraperitoneal
