    Coumarin derivatives have diverse structures and show various significant biological activities. Aiming to develop more potent coumarin derivatives for cancer treatment, a series of coumarin acrolein hybrids were designed and synthesized by using molecular hybridization approach, and investigated for their antiproliferative activity against A549, KB, Hela and MCF-7 cancer cells as well as HUVEC and LO2 human normal cells. The results indicated that most of the synthesized compounds displayed remarkable inhibitory activity towards cancer cells but low cytotoxicity on normal cells. Among all the compounds, 5d and 6e were the most promising compounds against different cancer cell lines, especially for A549 and KB cells. The preliminary action mechanism studies suggested that compound 6e, the representative compound, was capable of dose-dependently suppressing migration, invasion and inducing significant apoptosis. Furthermore, the combined results of network pharmacology and validation experiments revealed that compound 6e induced mitochondria dependent apoptosis via the PI3K/AKT-mediated Bcl-2 signaling pathway. In summary, our study indicated compound 6e could inhibit cell proliferation, migration, invasion and promote cell apoptosis through inhibition of PI3K/AKT signaling pathway in human oral epidermoid carcinoma cells. These findings demonstrated the potential of 3-(coumarin-3-yl)-acrolein derivatives as novel anticancer chemotherapeutic candidates, providing ideas for further development of drugs for clinical use.

    香豆素衍生物结构多样,具有多种重要的生物活性。为了开发更有效的香豆素衍生物用于癌症治疗,我们采用分子杂交方法设计并合成了一系列香豆素-丙烯醛杂化物,并研究了它们对 A549、KB、Hela 和 MCF-7 癌细胞以及 HUVEC 和 LO2 人类正常细胞的抗增殖活性。结果表明,合成的大多数化合物对癌细胞具有显著的抑制活性,但对正常细胞的细胞毒性较低。在所有化合物中,5d 和 6e 是对不同癌细胞株最有希望的化合物,尤其是对 A549 和 KB 细胞。初步作用机理研究表明,代表化合物 6e 能够剂量依赖性地抑制迁移、侵袭和诱导细胞显著凋亡。此外,网络药理学和验证实验的综合结果表明,化合物 6e 通过 PI3K/AKT 介导的 Bcl-2 信号通路诱导线粒体依赖性凋亡。综上所述,我们的研究表明化合物 6e 可通过抑制人口腔表皮样癌细胞的 PI3K/AKT 信号通路,抑制细胞增殖、迁移、侵袭并促进细胞凋亡。这些发现证明了 3-(香豆素-3-基)-丙烯醛衍生物作为新型抗癌化疗候选药物的潜力,为进一步开发临床用药提供了思路。

    STAT-3 are significant targets for cancer treatments. Here, we describe a class of very effective dual STAT-3 and c-MET inhibitors with coumarin-based thiazoles () as its scaffold. Spectroscopic evidence (NMR, HRMS, and HPLC) validated the structural discoveries of the new compounds. The cytotoxic activity of these compounds was also tested against a panel of cancer cells in accordance with US-NCI guidelines

    The underlying cause of spinal muscular atrophy (SMA) is a deficiency of the survival motor neuron (SMN) protein. Starting from hits identified in a high-throughput screening campaign and through structure activity relationship investigations, we have developed small molecules that potently shift the alternative splicing of the SMN2 exon 7, resulting in increased production of the full-length SMN mRNA and protein. Three novel chemical series, represented by compounds 9, 14, and 20, have been optimized to increase the level of SMN protein by >50% in SMA patient-derived fibroblasts at concentrations of <160 nM. Daily administration of these compounds to severe SMA Delta 7 mice results in an increased production of SMN protein in disease-relevant tissues and a significant increase in median survival time in a dose-dependent manner. Our work supports the development of an orally administered small molecule for the treatment of patients with SMA.
