Network pharmacology identified 78 EL-metastatic TNBC (mTNBC) overlapping targets as potential therapeutic targets of EL against mTNBC, with PPI and GMFA network enrichment uncovering key metastasis-associated pathways including Notch, TGF-β, TNF, and ErbB signaling. Molecular docking and 100 ns molecular dynamics simulations revealed stable binding of EL to several core oncogenic proteins (e.g., EGFR, PARP1, AURKB, SMAD4, CDK4), suggesting poly-pharmacological engagement. Genome-wide transcriptomic profiling of EL-treated cells coupled with GSEA revealed coordinated downregulation of oncogenic programs including E2F, G2/M checkpoint, MYC targets, EMT, and metabolic plasticity, alongside induction of NRF2 signaling and ferroptosis. This study reports, for the first time, transcriptome-wide effects of EL in MDA-MB-231 cells, linking its activity to the repression of stemness, invasion, and immune-evasive traits. Experimental validation via qPCR confirmed EL-mediated suppression of key molecular targets of TGF-β and Notch signaling pathways. EL also impaired cortactin expression and disrupted cytoskeletal remodeling, validated by immunofluorescence and flow cytometry studies, indicating attenuation of invasive machinery. Furthermore, EL reduced metastatic dissemination in a zebrafish xenograft model, reinforcing its in vivo anti-metastatic potential.

Onvansertib is currently under Phase II investigation to evaluate its safety and efficacy in patients with relapsed small cell lung cancer (SCLC). In this study, the efficacy, tolerability, and toxicity of onvansertib were comprehensively profiled using a large panel of 144 cancer cell lines and mouse models. We identified that SCLC cell lines are highly responsive to onvansertib. SCLC xenograft assays showed that daily oral administration of onvansertib at 60 mg/kg was more effective in tumor regression without inducing significant changes in body weight compared to a treatment cycle of 3 days of administration followed by 4 days of rest over a 3-week experimental period. However, in vivo toxicity studies revealed onvansertib-related mortality, clinical signs, and hematological adverse effects at the 60 mg/kg dose. Our findings collectively provide experimental evidence to support combination therapies or toxicity-salvaging low-dose regimens, as reflected in current clinical trials of onvansertib. Additionally, we conducted single-cell RNA-sequencing to elucidate the pharmacological mechanisms of onvansertib in SCLC with unprecedented resolution.

Preliminary screening for cytotoxicity and anti-inflammatory activity revealed that these structural modifications critically influenced bioactivity. Among the derivatives, compound 1a, bearing a β-D-galactosyl group at the para-position of the cinnamaldehyde phenyl ring, exhibited the most promising therapeutic potential. In contrast, replacing the β-D-galactosyl group with β-D-glucosyl (1b) or α-D-mannosyl (1c) residues resulted in loss of anti-inflammatory activity. Similarly, shifting the β-D-galactosyl group to the meta (1d) or ortho (1e) positions also abolished activity, highlighting the importance of both sugar identity and its positional attachment in determining function. Subsequent mechanistic studies focused on compound 1a and its effect on the NOD-, LRR- and pyrin domain-containing protein 3 (NLRP3) inflammasome, a central mediator in inflammatory disorders. Compound 1a effectively suppressed NLRP3 inflammasome activation by reducing mitochondrial damage and disrupting inflammasome complex assembly in macrophages. Furthermore, 1a promoted Sirt1-mediated autophagy, which contributed to additional inhibition of inflammasome activation. Notably, 1a inhibited not only the NLRP3 inflammasome but also the NLRC4 inflammasome in macrophages.
