Benazepril-based novel trizole derivatives are being explored as potential anticancer agents, designed with an N-substituted 1,2,3-triazole moiety linked to Benazepril's N-1 position via a methylene bridge. An ultrasound irradiated CuAAC method was used to prepare all these compounds and evaluated their anti-proliferative activities against cancer and drug-resistant cell lines. While some of these compounds demonstrated anti-proliferative activity towards leukemic cancer cell line K562, two of them displayed complete inhibitory activity. Interestingly, the compounds 5n and 5o showed potent activity against imatinib-resistant cell lines suggesting their promise to overcome cancer drug resistance. Furthermore, molecular docking analysis revealed that compounds 5n and 5o have higher predicted sensitivity towards ACE protein when compared to benazepril and lisinopril indicating their value as potential drug lead molecules. This research introduces a distinctive approach by employing ultrasound to facilitate CuAAC reactions in medicinal chemistry.

Patients with metastatic breast cancer face reduced quality of life and increased mortality rates, necessitating more effective anti-cancer strategies. Building on previous research that identified metastatic-niche-specific metabolic vulnerabilities, we investigated how a ketogenic diet enhances estrogen receptor (ER)-positive liver metastatic breast cancer's response to Fulvestrant (Fulv) treatment. Using in vitro cell lines and in vivo xenograft metastasis mouse models, we examined the molecular mechanisms of combining ER targeting with a ketogenic diet.

The orphan nuclear receptor NR2E3 has emerged as a potential tumor suppressor, yet its precise mechanisms in tumorigenesis require further investigation. Here, we demonstrate that the full-length protein isoform of NR2E3 instead of its short isoform activates wild-type p53 and is capable of rescuing certain p53 mutations in various cancer cell lines. Importantly, we observe a higher frequency of NR2E3 mutations in three solid tumors compared to the reference population, highlighting its potential significance in tumorigenesis.

The development of stable and standardized in vitro cytotoxicity testing models is essential for drug discovery and personalized medicine. Microfluidic technologies, recognized for their small size, reduced reagent consumption, and control over experimental variables, have gained considerable attention. However, challenges associated with external pumps, particularly inconsistencies between individual pumping systems, have limited the real-world application of cancer-on-a-chip technology.

The transforming growth factor β (TGF-β) type 1 receptor (ALK5) plays a key role in tumor microenvironment. Small-molecule inhibitors of TGFβR1 provides a prospective approach for the treatment of malignant tumors. In this study, a series of 4-((3-(tetrahydro-2H-pyran-4-yl)-1H-pyrazol-4-yl)oxy)quinoline derivatives were identified as novel, potential TGFβR1 inhibitors.
