    在全世界最常见的恶性肿瘤中,头颈部鳞状细胞癌(HNSCC)的特点是发病率和死亡率高。标准治疗方式的失败,比如手术,放射治疗,和化疗,需要深入了解与治疗抗性发展有关的复杂信号网络。肿瘤的侵袭性生长和高水平的内在或获得性治疗抗性是治疗失败的主要原因。这可能是HNSCC的癌症干细胞的存在的结果,已知它们具有自我更新能力,导致治疗抗性。使用生物信息学方法,我们发现MET的表达升高,STAT3和AKT与HNSCC患者总体生存率低相关。然后,我们评估了我们新合成的小分子HNC018作为新型抗癌药物的潜力。我们的计算机辅助结构表征和靶标鉴定研究预测,HNC018可以靶向这些与HNSCC有关的致癌标记。随后,HNC018已证明其对头颈部鳞状细胞癌细胞系的抗增殖和抗癌活性,随着对MET表现出更强的结合亲和力,STAT3和AKT比标准药物顺铂。克隆形成和肿瘤球体形成能力的降低显示了HNC018在降低致瘤性中的作用。重要的是,一项体内研究显示,在HNC018单独或联合顺铂治疗的异种移植小鼠模型中,肿瘤生长显著延迟.结合我们的发现,HNC018突出了药物样候选物的理想特性,可以被认为是治疗头颈部鳞状细胞癌的新型小分子。
    Amongst the most prevalent malignancies worldwide, head and neck squamous cell carcinoma (HNSCC) is characterized by high morbidity and mortality. The failure of standard treatment modalities, such as surgery, radiotherapy, and chemotherapy, demands the need for in-depth understanding of the complex signaling networks involved in the development of treatment resistance. A tumor\'s invasive growth and high levels of intrinsic or acquired treatment resistance are the primary causes of treatment failure. This may be a result of the presence of HNSCC\'s cancer stem cells, which are known to have self-renewing capabilities that result in therapeutic resistance. Using bioinformatics methods, we discovered that elevated expressions of MET, STAT3, and AKT were associated with poor overall survival in HNSCC patients. We then evaluated the therapeutic potential of our newly synthesized small molecule HNC018 towards its potential as a novel anticancer drug. Our computer-aided structure characterization and target identification study predicted that HNC018 could target these oncogenic markers implicated in HNSCC. Subsequently, the HNC018 has demonstrated its anti-proliferative and anticancer activities towards the head and neck squamous cell carcinoma cell lines, along with displaying the stronger binding affinities towards the MET, STAT3, and AKT than the standard drug cisplatin. Reduction in the clonogenic and tumor-sphere-forming ability displays HNC018\'s role in decreasing the tumorigenicity. Importantly, an vivo study has shown a significant delay in tumor growth in HNC018 alone or in combination with cisplatin-treated xenograft mice model. Collectively with our findings, HNC018 highlights the desirable properties of a drug-like candidate and could be considered as a novel small molecule for treating head and neck squamous cell carcinoma.

    如今,疾病机制的复杂性和单靶标疗法在恢复生物系统方面的不足不可避免地促使了多靶标疗法的策略,并对每个靶标进行单独分析。然而,它不适合处理目标之间或药物之间的冲突。随着高精度蛋白质结构预测人工智能的发布,大规模高精度蛋白质结构预测和对接成为可能。在这篇文章中,我们以治疗性低温(TH)为例,提出了一种多靶点药物发现方法。首先,我们通过AlphaFold2和RoseTTAFold对每组的所有蛋白质靶标进行了蛋白质结构预测。然后,QuickVina2用于蛋白质和药物之间的分子对接。对接后,我们使用PageRank对每组的单一药物和药物组合进行排序。ePharmaLib用于预测副作用目标。鉴于不同目标的权重存在差异,该方法可以有效地避免抑制有益蛋白质,同时抑制有害蛋白质。因此,它可以最大程度地减少不同剂量之间的冲突,并对时间治疗学友好。此外,该方法因其与生物信息学的高度兼容性而在精准医学中也具有潜力,并促进了药物基因组学和生物信息药理学的发展。
    Nowadays, the complexity of disease mechanisms and the inadequacy of single-target therapies in restoring the biological system have inevitably instigated the strategy of multi-target therapeutics with the analysis of each target individually. However, it is not suitable for dealing with the conflicts between targets or between drugs. With the release of high-precision protein structure prediction artificial intelligence, large-scale high-precision protein structure prediction and docking have become possible. In this article, we propose a multi-target drug discovery method by the example of therapeutic hypothermia (TH). First, we performed protein structure prediction for all protein targets of each group by AlphaFold2 and RoseTTAFold. Then, QuickVina 2 is used for molecular docking between the proteins and drugs. After docking, we use PageRank to rank single drugs and drug combinations of each group. The ePharmaLib was used for predicting the side effect targets. Given the differences in the weights of different targets, the method can effectively avoid inhibiting beneficial proteins while inhibiting harmful proteins. So it could minimize the conflicts between different doses and be friendly to chronotherapeutics. Besides, this method also has potential in precision medicine for its high compatibility with bioinformatics and promotes the development of pharmacogenomics and bioinfo-pharmacology.

    The management of glioblastomas (GBMs) is challenged by the development of therapeutic resistance and early disease recurrence, despite multi-modal therapy. This may be attributed to the presence of glioma stem cells (GSCs) which are known to survive radio- and chemotherapy, by circumventing death signals and inducing cell re-population. Recent findings suggest GSCs may be enriched by certain treatment modality. These necessitate the development of novel therapeutics capable of targeting GBM cell plasticity and therapy-resistant GSCs. Here, aided by computer-assisted structure characterization and target identification, we predicted that a novel 5-(2\',4\'-difluorophenyl)-salicylanilide derivative, LCC-09, could target dopamine receptors and oncogenic markers implicated in GBMs. Bioinformatics data have indicated that dopamine receptor (DRD) 2, DRD4, CD133 and Nestin were elevated in GBM clinical samples and correlated to Temozolomide (TMZ) resistance and increased aldehyde dehydrogenase (ALDH) activity (3.5-8.9%) as well as enhanced (2.1-2.4-fold) neurosphere formation efficiency in U87MG and D54MG GBM cell lines. In addition, TMZ-resistant GSC phenotype was associated with up-regulated DRD4, Akt, mTOR, β-catenin, CDK6, NF-κB and Erk1/2 expression. LCC-09 alone, or combined with TMZ, suppressed the tumorigenic and stemness traits of TMZ-resistant GBM cells while concomitantly down-regulating DRD4, Akt, mTOR, β-catenin, Erk1/2, NF-κB, and CDK6 expression. Notably, LCC-09-mediated anti-GBM/GSC activities were associated with the re-expression of tumor suppressor miR-34a and reversal of TMZ-resistance, in vitro and in vivo. Collectively, these data lay the foundation for further exploration of the clinical feasibility of administering LCC-09 as single-agent or combinatorial therapy for patients with TMZ-resistant GBMs.

    OBJECTIVE: Our goal in this study aims to explain the polypharmacological mechanism at the molecular level responsible for the effectiveness of a traditional Chinese medicine (TCM) prescription FTZ to treat hyperlipidemia and related disease.
    METHODS: By MDL(®) ISIS_Base 2.5, we constructed a compound database based on the FTZ constituents, which were detected in the rat serum after oral administration of the TCM through ultra-performance liquid chromatography/quadruple-time-of-flight mass-spectrometry (UPLC/Q-TOF-MS/MS) method. After validation of the virtual docking system, we used molecular screening by LigandFit which is a computational method for the shape-directed rapid docking of ligands to target protein active sites, to investigate the interactions between the components in database and lipid-modulating targets in the liver.
    RESULTS: In the prescription FTZ ingredients, there were sixteen constituents including jatrorrhizine, etc. showed potential effects towards the hyperlipidemia-related targets: HMG-CoA reductase (HMGR), squalene synthase (SQS), oxidosqualene cyclase (OSC), cholesteryl ester transfer protein (CETP), liver X receptor (LXR), farnesoid X receptor (FXR) and peroxisome proliferator-activated receptors (PPARα and PPARγ). Among the eight herbs in prescription FTZ, Rhizoma Coptidis (RC) plays the most important role in whole effect from FTZ on hyperlipidemia related disease.
    CONCLUSIONS: Our research demonstrated that Chinese medicine formula FTZ has multi-target synergistic effect on hyperlipidemia and suggests the pharmacodynamic material basis could be jatrorrhizine, berberrubine, berberine and salidroside.
