Host angiogenic reprogramming by Echinococcus multilocularis protoscoleces protein via PDGFR/PI3K/AKT cascade. (PubMed, Front Microbiol)
Interventions utilizing a range of inhibitors at the in vitro level, including the PDGFR-β inhibitor AG1296, the PI3K inhibitor LY294002, the AKT inhibitor MK2206, and the FAK inhibitor Y15, demonstrated that E. multilocularis protoscoleces protein (EmP) induces angiogenesis through PDGFR/PI3K/AKT/FAK signaling pathway. Our findings provide new perspectives on how E. multilocularis infection triggers pathological angiogenesis in the host liver, and may provide a novel anti-angiogenic therapeutic strategy against E. multilocularis infection.

Metabolite identification of ripretinib by UPLC-ESI-MS/MS: in silico prediction, in vitro metabolism, and stability assessment. (PubMed, Food Chem Toxicol)
Results highlighted neurotoxicity as a significant concern for RTB and its metabolites, while metabolite 1 exhibited hepatotoxicity and nephrotoxicity. The current study unveils metabolic profiles of RTB and helps to understand the biotransformation products-related toxicity.

Selective EV Protein Sorting and Pathway Perturbation in AML Upon Synergistic FLT3 and Hedgehog Pathway Inhibition. (PubMed, J Extracell Vesicles)
These findings were corroborated by comparative proteomics of EVs derived from AML patients and healthy donors. Ribosomal and ErbB signalling pathway proteins may play an important role in microenvironmental modulation by EVs, and Crenolanib treatment potentially acts by interfering with leukaemia niche formation.

Design, synthesis and biological evaluation of novel platelet-derived growth factor receptor-α (PDGFR-α) inhibitors based on 4-anilinoquinoline and 4-anilinoquinazoline scaffolds. (PubMed, Eur J Med Chem)
Novel 4-anilinoquinoline and 4-anilinoquinazoline hybrids were designed and synthesized as PDGFR-α inhibitors based on lenvatinib, ripretinib and sorafenib. Furthermore, molecular docking results showed that 6o could stably bind to the ATP site of PDGFR-α rationalizing their potent anti-PDGFR-α activity. Based on the above findings, compound 6o could be considered an effective anti-angiogenesis candidate.

Pharmacokinetics and Safety of Ripretinib in Participants with Hepatic Impairment: A Phase 1 Study. (PubMed, Adv Ther)
On the basis of the known safety profile of ripretinib, these increased ripretinib and combined ripretinib + DP-5439 exposures in participants with hepatic impairment are unlikely to be clinically relevant. Therefore, no dose adjustments are recommended for patients with gastrointestinal stromal tumor and hepatic impairment.

Gastrointestinal Stromal Tumor: Current Approaches and Future Directions in the Treatment of Advanced Disease. (PubMed, Hematol Oncol Clin North Am)
It covers the role of tyrosine kinase inhibitors (TKIs), specifically imatinib, and further treatment options, such as sunitinib, regorafenib, and ripretinib, as well as avapritinib for platelet-derived growth factor receptor alpha D842V mutations. In addition, this review emphasizes individualized treatment strategies within multidisciplinary expert teams, including surgery and other locoregional therapies, together with the importance of mutation-guided approaches, particularly for wild-type GISTs. Finally, it explores the potential of next-generation KIT inhibitors, combination therapies, and other investigational approaches.

Targeting ceramide transfer protein sensitizes AML to FLT3 inhibitors via a GRP78-ATF6-CHOP axis. (PubMed, Nat Commun)
Additionally, co-treatment of HPA-12 and Crenolanib is effective in FLT3-ITD+ and FLT3-TKD+ AML patients. The synergistic effects are found to be mediated by the endoplasmic reticulum stress-GRP78/ATF6/CHOP axis and mitophagy. Our data provide an effective strategy to enhance the efficacy of FLT3 inhibitors in AML.
