Additionally, we found that PIK-75 oc-HDL NP, but not free PIK-75 or oc-HDL NP alone, reduced the IC50 in the NCI-60 cell line panel and additional pancreatic cancer cell lines. These data demonstrate the first example of drug-loaded oc-HDL NP that actively target SR-B1 and kill cancer cells in vitro and in vivo, encouraging further development and translation to human patients.

It induced apoptosis activity in HepG2 cancer cells. Accordingly, compound 9 was proven to be an effective chemotherapeutic drug that targets PIM-1 in treating liver cancer.

These cyclin-dependent kinase (CDK)12/CDK13, CDK7, and phosphoinositide 3-kinase inhibitors, respectively, decreased metabolic activity in TNBC cell lines and promote a gene expression profile consistent with the reversal of the epithelial-to-mesenchymal transition, indicating these kinase networks potentially mediate metastatic behavior. These data identified novel kinase targets and kinase signaling pathways that drive metastasis in TNBC.

The latter group of cases with a recessive genetic pattern (GG vs. GC+ CC) showed enhanced susceptibility to promoting PDAC (OR = 1.7; 95% CI: 1.2-2.9; p = 0.04). Our findings indicate that genetic variation in CDKN2A was linked to the susceptibility of extending PDAC, suggesting the need for additional research in a broader, multi-center context to approve the possible significance of this gene as a novel indicator for the stratification of PDAC.

We demonstrate in our exploratory study that biomarkers involved in the process of EMT could have a prognostic impact in a cohort of patients with BC uniformly treated and with long-term follow-up. Genes known to be involved in EMT were associated with improved eribulin efficacy, while suggesting a poorer outcome with CDK4/6i.

Notably, CDDO-Me attenuates TNBC progression by accelerating EGFR degradation in cell-derived xenografts and patient-derived organoid models, highlighting its clinical application potential. Consequently, induction of EGFR degradation through MG degraders represents a viable therapeutic strategy for TNBC.

In contrast, related Type I1/2 inhibitors target wild-type EGFR but are less effective against resistant mutants. This shift in selectivity demonstrates that mutant-selective AABIs classify as "Type V" bivalent inhibitors.

Critical pharmacophoric features were extracted from the crystal structures of ErbB4-lapatinib, followed by virtual screening of the Chembl database to discover potential small molecule candidates. Furthermore, the ADMET profiles of 11 shortlisted candidates were assessed to verify their pharmacokinetic and toxicity properties, identifying Chembl310724, Chembl521284, and Chembl4168686 as promising inhibitors of ErbB4 kinase activity with the binding free energy (ΔGbind) values of -99.84, -89.42 and -86.06 kcal/mol, respectively. This integrated methodology not only enhances our understanding of ErbB4 inhibition but also sets a foundation for the rational design of targeted therapies addressing breast cancer with ErbB4 dependency.

We observed that phosphorylated proteoforms in the same proteoform family, such as eukaryotic initiation factor 4E binding protein 1 (4EBP1), were differentially regulated relative to the unphosphorylated proteoforms. Combining relative profiling of proteoforms within these proteoform families with individual proteoform profiling results in a more comprehensive picture of STS treatment-induced proteoform abundance changes that cannot be achieved using bottom-up methods.

Both docking studies revealed perfect binding of all identified ligands in active site pockets of AAK protein with similar amino acids of active sites as compared with standard BindingDB_50433632 compound and co-crystal ligand VX-680 binding mode of AAK protein. Therefore, it can be concluded that computational drug discovery approaches are meticulously implemented to identify potential AAKs inhibitors/modulators, and credential of the work was substantiated through the identification of three potential AAKs inhibitors/modulators that may hold significant promise for improving cancer management, however, need extensive biological assays or pre-clinical trials for assessing the efficacy profile of the identified compounds.

Among 86 compounds identified from M. charantia L., five molecules such as α-spinasterol (-9.7 kcal × mol-1), stigmasterol (-9.6 kcal × mol-1), stigmasta-7,22,25-trienol (-9.5 kcal × mol-1), campesterol (-9.5 kcal × mol-1), and stigmasta-7,25-dien-3beta-ol (-9.5 kcal × mol-1) and standard drug CCT245737 (-8.3 kcal × mol-1) displayed highest binding affinity with Chk-1...The estimation of binding free-energy derived from molecular docking was fully recognized by the Molecular Mechanics-Generalized Born Surface Area (MM-GBSA) produced from the MD simulation paths. Altogether, these five compounds may serve as effective inhibitors of Chk-1, thereby could be used to develop new medications for cancer treatment.

Given the rarity of ALK-positive NSCLC, this study contributes to add evidence through an expanded database and increased sample size, supporting previous suggestions that ICIs have limited effectiveness in patients positive for ALK.

Among the promising inhibitors tested, vatalanib, a VEGF-R inhibitor, demonstrated significant in vivo efficacy at inhibiting tumor growth and reducing tumor-associated myeloid cells, thereby underscoring its potential as a therapeutic agent. Our findings highlight specific kinase inhibitors with differential modulatory effects on HNSCC-associated myeloid subsets and caution the application of some as anti-cancer drugs. This experimental system may provide a robust platform for identifying new agents targeting tumor-associated myeloid cells in HNSCC and beyond, and for elucidating mechanistic insights into tumor-myeloid cell interaction.

Our results suggest that TFAM-induced changes of the mitochondrial genome lead to upregulated CDKN1A/p21 expression in colorectal cancer cells identifying p21 as a new possible linker between mitochondria and nucleus.

The combination of CDK4/6i and ET significantly improves PFS and OS compared to ET alone in both Asian and non-Asian patients with HR+/HER2-aBC. Although the magnitude of benefit appears to be independent of ethnicity, future clinical trials should devise a standardized method for stratifying patients by ethnicity to more effectively assess potential differences in treatment benefits.

The Herceptin-resistant breast cancer cell line JIMT-1 was used in an in vivo tumor model, and MMTV-erbB2 (Fo5) transgenic mice models were used to evaluate the efficacy and safety of ER121 as neoadjuvant. ER121 is a non-toxic small-molecule erbB kinase inhibitor and holds promise as an oral and systemic therapeutic agent for treating progressive erbB-driven tumors in therapeutic settings. Moreover, ER121 shows potential as a preventive therapy in neoadjuvant settings for erbB2-associated tumors and when administered systemically can dramatically limit erbB2 brain metastases in animal models.

The lead compound 2D7 (a.k.a. eCCA352) induces pan-OC activity and cell cycle arrest in the submicromolar range and was determined to inhibit Aurora kinase A, providing a new starting point to develop anticancer targeted agents against OC.

4i also demonstrated a high potential for oral bioavailability due to its adherence to Lipinski's rule of five. The molecular docking studies of 4i analog showed good binding mode with CDK6 active pocket through the formation of multiple interactions with its key amino acids.

MammaPrint Risk groups were then correlated to an 11-gene signature profile that measures absence of CDK4 phosphorylation, corresponding to Rb loss-of-function and, therefore, predictive of resistance to the CDK4i, Palbociclib... These data identify High 2 tumors as least likely to respond to CDK targeted inhibition compared to other MammaPrint Risk groups. The increasing scores of Rb loss-of-function signature, 'Rbsig,' was closely correlated with MammaPrint High 2. The 11-gene signature profile, defined by absent CDK phosphorylation and high cellular proliferation, was significantly more likely to be associated with MammaPrint High 2 Risk tumors.

The current state of knowledge on ALK inhibitors used in clinical practice is summarised in this research paper. Methods of diagnosis of abnormalities in ALK have been shown, and the review of research that contributed to the development of the next generation of ALK inhibitors has been presented.

We regarded ABL1, EGFR, and LCK as on-target kinases; among the two corresponding on-target kinase inhibitors, osimertinib and ponatinib emerged as on-target drugs whose target kinases were significantly activated. The remaining 26 kinases and seven kinase inhibitors were excluded as off-targets. Our pharmacoproteomic approach enabled the identification of on-target kinase inhibitors that are useful for drug repositioning.

Aim: We conducted network meta-analysis to assess cardiovascular toxicity of anaplastic lymphoma kinase-tyrosine kinase inhibitors (ALK-TKIs).Materials & Eleven articles involving 2855 patients and six interventions including crizotinib, alectinib, ceritinib, lorlatinib, brigatinib and chemotherapy were analyzed. No significant difference was observed in overall cardiovascular risk among ALK-TKIs. For vascular toxicity, crizotinib and ceritinib had a higher risk of thrombotic events than brigatinib. Crizotinib and lorlatinib were more likely to cause blood pressure abnormalities. Clinicians should carefully monitoring cardiovascular events when ALK-TKIs used in NSCLCs patients with baseline cardiovascular diseases.

Combination kinase inhibitors with immunotherapy as first-line therapy are safe and effective for the treatment of unresectable ATC, especially with BRAF V600E mutation.

These results underscore the pivotal role of CERK inhibition in bolstering OAcGD2 synthesis, thus, presenting a promising strategy to increase the efficacy of anti-OAcGD2-based immunotherapy in patients with neuroectodermal tumors. By shedding light on this intricate interplay, our study paves the way for innovative therapeutic strategies poised to revolutionize the treatment landscape for these aggressive malignancies.

The three promising anti-proliferative hybrids (1a, 8a, 13a) were selected for the assessment of their in vitro inhibitory kinase activity against CDK2/GSK3β using roscovitine (IC50 = 0.88 μg mL-1) and CHIR-99021 (IC50 = 0.07 μg mL-1) as references, respectively...Moreover, it resulted in an increase in Bax and caspase-3 with a decrease in Bcl-2 levels in HepG2 cells compared with untreated cells. Finally, in silico drug likeness/ADME prediction for the three potent compounds as well as a molecular docking simulation study were conducted in order to explore the binding affinity and interactions in the binding site of each enzyme, which inspired their usage as anti-proliferative leads for further modification.

Additionally, the binding affinity, residence time, and even JNK isoform specificity can be fine-tuned by adjusting the substitution pattern or using divergent and orthogonal synthetic elaboration of the warhead. Taken together, the cyclic warheads presented in this study will be a useful tool for medicinal chemists for the deliberate design of safer and functionally fine-tuned covalent inhibitors.

Finally, we show that ERK activation promotes resistance to TRK kinase inhibition and identify MEK inhibition as a potential combination therapy. These models will be invaluable tools to study therapy resistance of NTRK fusion tumors.

Molecular simulation studies revealed Dabrafenib's thermodynamically stable interactions (ΔG), tighter binding, and less structural deviation in the order EGFR > HER-2 > ER > PR as compared to Palbociclib (HER-2 > ER > PR = EGFR). These results indicate that Dabrafenib, compared to Palbociclib, more effectively regulates breast cancer cell proliferation through specific interactions with hormonal and growth factor receptors towards a repurposing approach.

This analysis culminated in the identification of a hydroxylamine-bearing, dual cSRC/BCR-ABL1 kinase inhibitor 16a that exhibits a marked reduction in P-gp-mediated efflux ratio and potent activity in a Ph+ patient-derived cell line (K562) and an MDR-Ph+ patient-derived cell line (K562/Dox) overexpressing P-gp. Overall, we demonstrate that the P-gp-mediated efflux ratio can be minimized by computationally driven optimization of the molecular dipole and/or cpKa without recourse to intramolecular hydrogen bonds.
