dovitinib (TKI258)

This study highlights FGFR4, FLT1, and WNT5A as key diagnostic and therapeutic biomarkers for CRC, with their relevance varying based on the tumor's site of origin. Leveraging these findings, we propose Dovitinib and Nintedanib as promising targeted therapies for CRC. These insights can enhance current treatment strategies and pave the way for future in vivo and in vitro studies, driving progress in CRC research and therapy.

Additionally, Dov inhibited ferroptosis by regulating the NRF2/HMOX1 axis and lipid peroxidation and protected against concanavalin A-induced acute liver injury. Thus, our work revealed that Dov is a dual inhibitor of necroptosis and ferroptosis and provides a potential therapeutic drug or combination approach for treating necroptosis- and ferroptosis-related diseases.

Sunitinib, regorafenib, and ripretinib are currently approved as standard second-, third-, and fourth-line therapies, each demonstrating efficacy against distinct mutational profiles. Avapritinib, notably effective against PDGFRA D842V mutations, represents a milestone for previously untreatable subgroups. Several alternative agents-such as nilotinib, masitinib, sorafenib, dovitinib, pazopanib, and ponatinib-have shown varying degrees of success in refractory cases or specific genotypes. Investigational compounds, including crenolanib, bezuclastinib, famitinib, motesanib, midostaurin, IDRX-42, and olverembatinib, are under development to address resistant or wild-type GISTs...Future strategies include precision medicine approaches such as ctDNA-guided therapy, rational drug combinations, and novel drug delivery systems to optimize bioavailability and reduce toxicity. Ongoing research will be crucial for refining treatment sequencing and expanding therapeutic options, especially for rare GIST subtypes.

Among them, 3,5-di-O-caffeoylquinic acid, 3-O-caffeoylquinic acid, myricetin, quercetin, stigmasterol, kaempferol, isorhamnetin, rhamnetin, and hesperitin featured strong predicted binding affinities to the HER1, HER2, and HER4 growth factor receptors, comparable to those of standard anti-cancer drugs such as gefitinib and dovitinib. Further pharmacokinetic assessments, including bioavailability and toxicity analyses, identified compounds with favorable drug-likeness properties and minimal toxicity risks, except for myricetin and quercetin. These findings underscore the potential of Salicornia-derived phytochemicals as promising candidates for the development of safe, novel, and effective anti-cancer agents targeting GFRs, contributing to the advances in precision oncology, pending further validation through in vitro and/or in vivo experiments.

Additionally, we screened for potential small molecule inhibitors, identifying four promising candidates, including Dovitinib, S-Adenosylmethionine, Guanosine-5',3'-tetraphosphate, and Neomycin, which exhibited favorable drug-like characteristics. In conclusion, our multifaceted approach demonstrates the significant potential of LNA-anti-miR-19b-3p as a therapeutic option for TNBC patients, and the small molecule inhibitors we've uncovered could open new avenues for treating this aggressive form of breast cancer.

Then we detected 10 repurposable drug molecules (Irinotecan, Imatinib, Telaglenastat, Olaparib, RG-4733, Sorafenib, Sitravatinib, Cabozantinib, Abemaciclib, and Dovitinib.) by molecular docking with KGs-mediated receptor proteins. Their ADME/T analysis and cross-validation with the independent receptors, also supported their potent against ccRCC. Therefore, these outputs might be useful inputs/resources to the wet-lab researchers and clinicians for considering an effective treatment strategy against ccRCC.

Finally, sKGs-guided top-ranked three repurposable drug molecules (Digoxin, Imatinib, and Dovitinib) were recommended as the common treatment for both T2D and ccRCC by molecular docking and ADME/T analysis. Therefore, the results of this study may be useful for diagnosis and therapies of ccRCC patients who are also suffering from T2D.

Next, we explored the latest FLT3-targeting PROTACs developed in the past few years such as quizartinib-based PROTACs, dovitinib-based PROTACs, gilteritinib-based PROTACs, and others. Then, we followed with a deep analysis of their advantages regarding potency improvement and overcoming AML drug resistance. Finally, we discussed the challenges facing these chimeric molecules with proposed future solutions to circumvent them.

Current clinical trials, including those evaluating FGFR inhibitors like erdafitinib, lucitanib, and dovitinib, have demonstrated mixed outcomes, underscoring the complexity of FGFR signaling in breast cancer. In conclusion, targeting FGFR signaling in ER+ breast cancer presents both challenges and opportunities. A deeper understanding of the molecular mechanisms and resistance pathways is crucial for the successful integration of FGFR inhibitors into clinical practice, aiming to improve outcomes for patients with endocrine-resistant breast cancer.

Also, PharmacoGx data indicated that the expression level of SDHB was correlated with drug sensitivity to Crizotinib and Dovitinib. Our findings highlight the potential association between alterations in the expression of genes such as HOXC6, HOXC13, HOXC8, TBX15, SDHB, COX5A, and UQCRC1 and increased mortality rates in CRC patients. As revealed by the PPI network, these genes exhibited the most connections with other genes linked to survival.

Ligand-based virtual screening and molecular docking were performed, resulting in the selection of three lead compounds (CID_135698391, CID_135453100, CID_136599608) with superior binding affinities compared to the reference compound dovitinib...Overall, small-molecule compounds CID_135453100 and CID_136599608 showed promising binding interactions and stability, suggesting their potential as direct inhibitors of STK17B. These findings could contribute to the exploration of novel therapeutic options targeting STK17B in cancer treatment.Communicated by Ramaswamy H. Sarma.

Bortezomib and Axitinib exhibited high efficacy on the patient's sample...Other FGFR inhibitors, including Olverematinib, AZD4547, Axitinib, Cediranib, Dovitinib, and Lenvatinib, also demonstrated exquisite sensitivity. Despite extensive screening, no other single agents or drug combinations exhibited increased effectiveness in the ZMYM2: : FGFR1 transformed BaF3 cells except for Trametinib, a MEK inhibitor, and the combination of Belvarafenib (RAF inhibitor) and Gilteritinib (FLT3 inhibitor)... Ex vivo drug sensitivity assays demonstrated the highly selective efficacy of FGFR inhibitors in ZMYM2: : FGFR1 fusion-positive leukemia cells and a fusion-expressing BaF3 cell line. Mutations in the FGFR1 kinase domain (ZMYM2: : FGFR1 F1171L) could contribute to Ponatinib insensitivity. These ex vivo drug screening results provide further support for ongoing clinical trials which are investigating the use of single agent Pemigatinib and other FGFR1 inhibitors for the treatment of patients with FGFR1-fusion positive leukemias.
