Summary: Cardiac glycoside neriifolin inhibits the malignancy of prostate cancer cells by activating endoplasmic reticulum stress (ERS), which increases DNA damage and apoptosis. This study found that neriifolin significantly inhibits cell growth and induces apoptosis in prostate cancer cells. Transcriptome sequence analysis shows that neriifolin induces DNA damage and double strand breaks (DSBs), and activates ERS pathway. Overall, Neriifolin may be a potential chemotherapeutic agent for prostate cancer treatment.

Summary: Fifteen cardiac glycosides (CGs) were isolated from Digitalis lanata Ehrh, including three new compounds (1-3). Their structures were determined and confirmed using various spectroscopic techniques. The cytotoxic activities of these CGs were evaluated against three human cancer cell lines, showing strong activities. Compound 1 was found to induce cell cycle arrest and inhibit the expression of vasohibin-2 (VASH2). Moreover, it exhibited concentration-dependent inhibition of angiogenesis in the chorioallantoic membrane (CAM) model.

Summary: Caspases play a crucial role in apoptosis initiation and are also involved in non-apoptotic functions like proliferation and differentiation. Altered caspase function in cancer can have both preventive and promoting effects on tumor formation, impacting cancer treatment strategies. A comprehensive understanding of the dual role of caspases is essential for the development of successful cancer therapeutic approaches.

Summary: Ovarian cancer is a major issue in gynecological oncology, and research on diagnostic markers like caspase-3, -8, and -9 is ongoing. This study found significantly decreased levels of these caspases in ovarian cancer patients compared to healthy controls, suggesting a link to immune system disturbances and potential for future diagnostic use, pending further research.

Summary: Cytotoxic drugs kill cancer cells through apoptosis, but recent research has found that pyroptosis can inhibit cell proliferation and shrink tumors. Pyroptosis and apoptosis are caspase-dependent programmed cell death processes. Inflammasomes activate caspase-1 and latent cytokines, including IL-1 beta and IL-18, to induce pyroptosis by cleaving gasdermin E (GSDME). Understanding the cellular and molecular mechanisms of caspase-3 and GSDME-mediated programmed cell death, specifically pyroptosis, may lead to potential targets for cancer treatment.

Summary: This article presents the hypothesis that premature placenta apoptosis could be a potential cause of preterm birth, supported by evaluating gene expression. The study found that during pregnancy, the expression of apoptosis-related genes in the placenta is low, but the expression of the apoptosis inhibitor XIAP is high. However, at the onset of preterm labor, the expression of apoptosis-related genes increases significantly, potentially initiating preterm birth.

Summary: This study explores the mechanism of chemotherapy-induced pyroptosis and its role in mediating the progression and chemoresistance of pancreatic ductal adenocarcinoma (PDAC). It is found that first- and second-line chemotherapeutic drugs against PDAC induce concurrent pyroptosis and apoptosis. Moreover, it is demonstrated that pyroptosis promotes the invasiveness and chemoresistance of PDAC cells, and targeting pyroptosis can enhance the sensitivity of PDAC cells to chemotherapy.

Summary: Two unnatural regioisomeric glycosylated Gilvocarcin analogues were proposed as model compounds to study the biosynthetic origin of Gilvocarcins and the proposed O- to C-glycoside migration in the evolution of Angucycline antibiotics. The analogue with weak antibiotic activity compared to Gilvocarcin M was synthesized using a regio-divergent synthetic pathway with a Mitsunobu-like invertive cyclictolization reaction to install the carbasugar motif.

Summary: A one pot alkylative carboxylation reaction of 2-acetylfuran was developed for the synthesis of methyl beta-ketoesters. The beta-keto-ester product was used for the asymmetric synthesis of a C-7 pyranone precursor for a Pd-glycosylation reaction, with the ultimate goal of synthesizing natural products containing pyran rings, such as Aspergillide C.

Summary: The development and application of asymmetric synthesis of oligosaccharides from achiral starting materials are reviewed in this article. This approach involves the use of asymmetric catalysis to synthesize optically pure furan alcohols, in combination with Achmatowicz oxidative rearrangement for the synthesis of various pyranones. Additionally, diastereoselective palladium-catalyzed glycosylation and subsequent diastereoselective post-glycosylation transformation are used for the synthesis of oligosaccharides.

Summary: The full account of a de novo asymmetric total synthesis of (+)-monanchorin, a guanidine alkaloid natural product, has been reported. The optimized synthesis route enables the access to both enantiomers of the compound in nine steps starting from the commodity chemicals furan and caproic acid. The synthesis relied on various reactions, including asymmetric Noyori hydrogen transfer reduction, Achmatowicz rearrangement, diastereoselective palladium-catalyzed glycosylation, reductive amination, and acid-catalyzed bicyclic guanidine mixed acetal formation.

Summary: The study identified a natural product, SL0101, that binds specifically to RSK1/2 by inducing conformational rearrangement, but not to RSK3/4 due to a single amino acid difference. Kinetic analysis revealed that regions outside of the N-terminal kinase domain also contribute to stable inhibitor binding towards RSK2. Additionally, a modification on SL0101 was discovered to form a highly stable inhibitor complex with RSK2, suggesting potential for identifying RSK2-specific inhibitors.
