    Hederagenin (HG) is a natural pentacyclic triterpenoid that can be isolated from various medicinal herbs. By modifying the structure of HG, multiple derivatives with superior biological activities and safety profiles have been designed and synthesized. Accumulating evidence has demonstrated that HG and its derivatives display multiple pharmacological activities against cancers, inflammatory diseases, infectious diseases, metabolic diseases, fibrotic diseases, cerebrovascular and neurodegenerative diseases, and depression. Previous studies have confirmed that HG and its derivatives combat cancer by exerting cytotoxicity, inhibiting proliferation, inducing apoptosis, modulating autophagy, and reversing chemotherapy resistance in cancer cells, and the action targets involved mainly include STAT3, Aurora B, KIF7, PI3K/AKT, NF-κB, Nrf2/ARE, Drp1, and P-gp. In addition, HG and its derivatives antagonize inflammation through inhibiting the production and release of pro-inflammatory cytokines and inflammatory mediators by regulating inflammation-related pathways and targets, such as NF-κB, MAPK, JAK2/STAT3, Keap1-Nrf2/HO-1, and LncRNA A33/Axin2/β-catenin. Moreover, anti-pathogen, anti-metabolic disorder, anti-fibrosis, neuroprotection, and anti-depression mechanisms of HG and its derivatives have been partially elucidated. The diverse pharmacological properties of HG and its derivatives hold significant implications for future research and development of new drugs derived from HG, which can lead to improved effectiveness and safety profiles.

    NAD+依赖性脱乙酰酶SIRT7是DNA损伤反应(DDR)的关键调节因子,也是开发癌症疗法的有希望的药物靶标。然而,在SIRT7调制器发现方面取得了有限的进展。这里,我们应用基于肽的脱乙酰酶平台进行SIRT7酶促评估,并成功鉴定出一种有效的SIRT7抑制剂YZL-51N。我们最初从蟑螂(美洲大猩猩)提取物中分离出生物活性YZL-51N,然后开发了该化合物的从头合成。进一步的研究表明,YZL-51N通过占据NAD结合袋而损害了SIRT7的酶活性。YZL-51N减弱了电离辐射(IR)在结直肠癌细胞中诱导的DNA损伤修复,并与依托泊苷联合使用时表现出协同抗癌作用。总的来说,我们的研究不仅从昆虫资源中鉴定出YZL-51N为选择性SIRT7抑制剂,但也证实了其通过干扰DNA损伤修复过程在联合化学放疗中的潜在用途。
    The NAD+-dependent deacetylase SIRT7 is a pivotal regulator of DNA damage response (DDR) and a promising drug target for developing cancer therapeutics. However, limited progress has been made in SIRT7 modulator discovery. Here, we applied peptide-based deacetylase platforms for SIRT7 enzymatic evaluation and successfully identified a potent SIRT7 inhibitor YZL-51N. We initially isolated bioactive YZL-51N from cockroach (Periplaneta americana) extracts and then developed the de novo synthesis of this compound. Further investigation revealed that YZL-51N impaired SIRT7 enzymatic activities through occupation of the NAD+ binding pocket. YZL-51N attenuated DNA damage repair induced by ionizing radiation (IR) in colorectal cancer cells and exhibited a synergistic anticancer effect when used in combination with etoposide. Overall, our study not only identified YZL-51N as a selective SIRT7 inhibitor from insect resources, but also confirmed its potential use in combined chemo-radiotherapy by interfering in the DNA damage repair process.

    高盐(HS)消耗是通过干扰免疫稳态的多种自身免疫性疾病的危险因素。然而,HS加重类风湿性关节炎(RA)发病机制的确切机制尚不明确.在这里,我们发现,在HS暴露后PDPK1和SGK1的磷酸化增强减弱了FoxO1的表达,从而增强了CD4T细胞的糖酵解能力,导致Th17增强但Treg程序受损。GSK2334470(GSK),PDPK1/SGK1双重抑制剂,有效减轻HS诱导的糖酵解能力增强和IL-17A的过度产生。因此,在胶原诱导的关节炎(CIA)模型中,GSK的给药明显减轻了HS加重的RA进展。总的来说,我们的数据表明,HS消费通过PDPK1-SGK1-FoxO1信号传导破坏Th17/Treg稳态,而GSK可能是临床上对抗RA进展的可行药物。
    High salt (HS) consumption is a risk factor for multiple autoimmune disorders via disturbing immune homeostasis. Nevertheless, the exact mechanisms by which HS exacerbates rheumatoid arthritis (RA) pathogenesis remain poorly defined. Herein, we found that heightened phosphorylation of PDPK1 and SGK1 upon HS exposure attenuated FoxO1 expression to enhance the glycolytic capacity of CD4 T cells, resulting in strengthened Th17 but compromised Treg program. GSK2334470 (GSK), a dual PDPK1/SGK1 inhibitor, effectively mitigated the HS-induced enhancement in glycolytic capacity and the overproduction of IL-17A. Therefore, administration of GSK markedly alleviated HS-exacerbated RA progression in collagen-induced arthritis (CIA) model. Collectively, our data indicate that HS consumption subverts Th17/Treg homeostasis through the PDPK1-SGK1-FoxO1 signaling, while GSK could be a viable drug against RA progression in clinical settings.

    雷公藤甲素(TP),从传统中草药雷公藤钩(TWHF)中分离出的活性成分,显示出治疗炎症相关疾病的巨大希望。然而,其潜在的肾毒性作用仍然令人担忧。TP诱导的肾毒性的潜在机制尚不充分阐明,特别是在单细胞分辨率下。因此,对来自对照和TP处理的小鼠的肾组织进行单细胞RNA测序(scRNA-seq),以产生对TP处理后的肾细胞图谱的全面描述。TP暴露后观察到肾单位上皮细胞的异质性反应,将细胞亚型的不同易感性归因于过度的活性氧和增加的炎症反应。此外,TP通过激活内皮细胞免疫和损伤成纤维细胞破坏血管功能。TP处理还观察到严重的免疫细胞损伤和促炎性Macro_C1细胞的激活。此外,配体-受体串扰分析显示,针对Macro_C1细胞的SPP1(骨桥蛋白)信号通路是由TP处理触发的,这可能会促进Macro_C1细胞的浸润,加剧肾毒性。总的来说,这项研究提供了在单细胞分辨率下TP相关肾毒性的转录组特征和细胞组成的全面信息,可加强对TP肾毒性发病机制的认识,为发现新的治疗靶点改善TP肾毒性提供有价值的线索。
    Triptolide (TP), an active component isolated from the traditional Chinese herb Tripterygium wilfordii Hook F (TWHF), shows great promise for treating inflammation-related diseases. However, its potential nephrotoxic effects remain concerning. The mechanism underlying TP-induced nephrotoxicity is inadequately elucidated, particularly at single-cell resolution. Hence, single-cell RNA sequencing (scRNA-seq) of kidney tissues from control and TP-treated mice is performed to generate a thorough description of the renal cell atlas upon TP treatment. Heterogeneous responses of nephron epithelial cells are observed after TP exposure, attributing differential susceptibility of cell subtypes to excessive reactive oxygen species and increased inflammatory responses. Moreover, TP disrupts vascular function by activating endothelial cell immunity and damaging fibroblasts. Severe immune cell damage and the activation of pro-inflammatory Macro_C1 cells are also observed with TP treatment. Additionally, ligand-receptor crosstalk analysis reveals that the SPP1 (osteopontin) signaling pathway targeting Macro_C1 cells is triggered by TP treatment, which may promote the infiltration of Macro_C1 cells to exacerbate renal toxicity. Overall, this study provides comprehensive information on the transcriptomic profiles and cellular composition of TP-associated nephrotoxicity at single-cell resolution, which can strengthen the understanding of the pathogenesis of TP-induced nephrotoxicity and provide valuable clues for the discovery of new therapeutic targets to ameliorate TP-associated nephrotoxicity.
