Summary: Cancer is a serious health issue with available chemotherapeutic drugs being highly toxic and lacking selectivity. Advances in science have illuminated molecular pathways responsible for cancer, leading to the development of targeted anticancer agents, such as quinazoline derivatives. These agents act by inhibiting various protein kinases and other molecular targets, offering new opportunities for more effective cancer treatment.

Summary: This study designed a series of novel G9a/GLP covalent inhibitors and discovered that compound ZZM-1220 exhibited strong anti-proliferative activity against triple-negative breast cancer. The drug could covalently bind to G9a/GLP and inhibit the production of H3K9me2, induce tumor cell apoptosis, and block the cell cycle progression. Moreover, ZZM-1220 demonstrated persistent inhibitory effects. Thus, ZZM-1220 holds promise as a lead compound for the development of G9a/GLP covalent inhibitors for the treatment of triple-negative breast cancer.

Summary: Hematopoietic progenitor kinase 1 (HPK1) is a validated target in pre-clinical immune oncology due to its regulation of critical signaling pathways in immune cells. Inhibiting HPK1 enhances T cell sensitivity to activation and anti-tumor activity in mice, suggesting its potential for enhancing anti-tumor immune response. Through structure-based drug design, potent HPK1 inhibitors were discovered with nanomolar potency in biomarkers and sustained elevation of IL-2 cytokine secretion.

Summary: Dynamic changes in protein-protein interaction networks have significant implications for cellular functions and human diseases. Our study presents a quantitative mass spectrometry-based chemoproteomic method called kinobead competition and correlation analysis (kiCCA) that enables rapid and extensive profiling of kinase interactomes. Using kiCCA, we identified context-dependent kinase interactome changes in diverse cancer lines and discovered potential drug targets. Our findings highlight the importance of studying kinase interactome dynamics for understanding cellular signaling in health and disease.

Summary: The efficacy of quinazoline-based antiglioma agents is attributed to their effects on microtubule dynamics and inhibition of multiple intracellular targets. Quinazolines not only cause microtubule depolymerization, but also act as low nanomolar inhibitors of EGFR, VEGFR-2, and PDGFR-α. This multitarget activity demonstrates their potential antitumor effects by targeting multiple pathways.

Summary: Compound 1 with pyrazolo[1,5-a]quinoxalin-4(5H)-one scaffold was identified as a hit for inhibiting PI3K alpha activity through virtual screening. Structural modifications based on similarity search and molecular docking yielded a novel series of pyrazolo[1,5-a]quinoxalin-4(5H)-one derivatives. The most potent compound 49b exhibited improved PI3K alpha inhibitory activity with good isoform selectivity and demonstrated promising pharmacokinetic properties. Further development of compound 49b as a potential PI3Ka inhibitor is warranted.

Summary: PRMTs are emerging as attractive therapeutic targets due to their regulation of essential biological processes such as transcription, splicing, RNA biology, DNA damage response, and cell metabolism, which are often disrupted in diseases. Understanding how these enzymes support cancer cell growth in specific metabolic contexts or in the presence of certain mutations has provided the rationale for targeting them in oncology, with ongoing inhibitor development and in-depth mechanistic investigations guiding future clinical development.

Summary: Combining denaturant dependence of hydrogen-deuterium exchange (HDX) and molecular dynamics (MD) allows for accurate identification of individual hydrogen bonds breaking and mapping the free energy surface (FES) of proteins. The new and extremely fast MD package Upside has been shown to accurately model protein folding compared to all-atom methods. By modifying the energy function using machine-learning, Upside's accuracy has significantly improved in replicating HDX data and protein stability. However, challenges remain in accurately calculating FESs in simulations.

Summary: Autophagy plays a crucial role in tumor initiation and progression, but targeting it in cancer treatment is challenging due to genetic or epigenetic factors. However, dysregulation of mitochondrial translation caused by CBFB deficiency can sensitize tumors to autophagy inhibition. CBFB deficiency leads to elevated autophagy and mitophagy in estrogen receptor-positive breast tumors, making them hypersensitive to autophagy inhibition. Inhibiting autophagy selectively eliminates breast tumor cells with mitochondrial translation defects resulting from CBFB deficiency.

Summary: DCAF1 serves as a subunit for RING-type CRL4(DCAF1) and HECT family EDVPDCAF1 E3 ubiquitin ligases in substrate recruitment. The WDR domain of DCAF1 acts as a binding platform for substrate proteins and is targeted by HIV and SIV lentiviral adaptors. This study used a proteome-scale drug-target interaction prediction model to identify ligands for the DCAF1 WDR domain through biophysical screening and X-ray crystallography, confirming the selective binding of a predicted ligand. The findings demonstrate the successful application of artificial intelligence-enabled virtual screening methods in the absence of previously known ligands.

Summary: Cbl-b, a RING-type E3 ubiquitin ligase, negatively regulates immune cell activity and is considered an attractive target for cancer immunotherapy. A novel Cbl-b inhibitor, C7683, binds strongly to Cbl-b and inhibits its activity by locking the protein in an inactive conformation. This study provides structural insights into the inhibition mechanism of Cbl-b.
