Investigation of ribociclib, abemaciclib and palbociclib resistance in ER+ breast cancer cells reveal potential therapeutic opportunities`. (PubMed, Sci Rep) - "CDK4/6i-resistant cell lines (MCF7rR, MCF7rA, MCF7rP, T47DrR, T47DrA, and T47DrP) were isolated and evaluated for their aggressive phenotypes, cross-resistance, transcriptomic changes, and sensitivity to volasertib (PLK1 inhibitor) and barasertib (AukB inhibitor). We conclude that cell cycle upregulation leading to G2/M progression is a key route for CDK4/6i resistance. AukB or PLK1 inhibitors that block G2/M phase could be a promising strategy."

The current landscape of quinazoline derivatives with in vivo anticancer therapeutic potential-part I. (PubMed, Future Med Chem) - "Moreover, several quinazoline hybrids, exemplified by Fruquintinib (quinazoline-benzofuran hybrid) and Barasertib (quinazoline-pyrazole hybrid), have already been applied in clinics for cancer therapy, indicating that the rational design of quinazoline hybrids may provide valuable chemotherapeutics for cancer therapy. This review outlines the current scenario of the in vivo anticancer therapeutic potential of quinazoline hybrids, together with modes of action, toxicity, and pharmacokinetic properties, developed from 2015 onwards, aiming to provide promising candidates for further preclinical/clinical evaluations and to facilitate further rational design."

Evaluation of the effects of MDM2 inhibitor and epigenetic modifiers in combination with AURKB inhibitors for treating lung cancer (AACR 2025) - "We also examined the anti-cancer effects of RG-7388, SAHA, CM-272, and Barasertib (an AURKB inhibitor), in modulating cell cycle regulation...Our findings confirm that AURKB levels can be down-regulated by using the combination of MDM2 inhibitors and epigenetic regulators such as SAHA and CM-272. However, the therapeutic efficiency of these combinations needs to be verified using in vivo experimental models."

Concurrent inhibition of the serine/threonine protein kinase AURKB and the fatty acid oxidation enzyme CPT1A demonstrates synthetic lethality in preclinical glioblastoma models (AACR 2025) - "Remarkably, the selective AURKB inhibitor barasertib was found to potently suppress the growth of established GBM cell lines, patient-derived xenograft models, and neurosphere cultures at low, nanomolar concentrations. Furthermore, the BH3-mimetic ABT263 was found to reduce the growth of GBM lines in the context of AURKB loss of function, likely due to the heightened dependence on mitochondrial metabolism. These findings uncover a previously unappreciated role for AURKB in regulating GBM metabolism and provide a strong rationale for further developing AURKB-targeted therapies, potentially in combination with metabolic inhibitors and BH3-mimetics, to improve clinical outcomes for patients with GBM."

Co-inhibition of Aurora kinase B and SUV4-20H induces synthetic lethality in Wild-type p53 deficient cancer cells. (PubMed, Mol Cancer Ther) - "Barasertib (AZD2811) targets the mitotic kinase Aurora B (AURKB) and is in current clinical trials for various cancers. Lastly, we found in two different p53 mutated cell line tumor models that barasertib plus A196 has greater anti-tumor activity than either single agent. Our results suggest co-targeting of AURKB and SUV4-20H1/2 could be effective against p53-mutated or deficient cancers, including TNBCs in which approximately 80% of cases are p53 mutated."

Structural characterization of Aurora kinase B modulation by Epigallocatechin gallate: Insights from docking and dynamics simulations. (PubMed, J Mol Graph Model) - "Synthetic inhibitors like AZD1152 and ZM447439 show selectivity for AURKB but often lack specificity due to high homology within the aurora kinase family. The study also noted transitions in the overall protein secondary structures, such as turn to coil, coil to sheet, and coil to helix, contributing to a stable structure upon EGCG binding. These findings highlight the complex interplay between EGCG and AURKB, providing insights into the conformational dynamics and structural alterations induced by this interaction, which has implications for reducing glioma cell chemosensitivity to therapeutic drugs."

Evaluation of ribociclib, abemaciclib and palbociclib resistance in ER+ breast cancer cells reveal novel therapeutic opportunities in ER+/HER2- breast cancers (SABCS 2024) - "CDK4/6i resistant and sensitive cells were evaluated for spheroid forming ability, cell cycle progression, apoptosis, cross resistance to other CDK4/6i, whole genome RNA sequencing, and cisplatin/volasertib (PLK1 inhibitor)/barasertib (Arora kinase B inhibitor) sensitivity. In ER+/ HER2− BCs, pathways to resistance to CDK4/6i therapy are complex and diverse. PLK1 or Aurora Kinase B targeting could be an attractive therapeutic strategy in certain CDK4/6i resistant ER+ BCs."

Cell cycle inhibitors activate hypoxia-induced DDX41-STING pathway to mediate anti-tumor immune response in liver cancer. (PubMed, JCI Insight) - "We demonstrated that Paclitaxel (microtubule stabilizer), Palbociclib (cyclin dependent kinase 4/6 inhibitor), AZD1152 and GSK1070916 (aurora kinase B inhibitors) have anti-cancer functions beyond arresting cell cycle. We observed a trend that Paclitaxel suppressed STINGWT HCC more effectively than STINGKO HCC, suggesting that STING might contribute to the anti-tumor effects of Paclitaxel. Our study revealed the immune-mediated tumor-suppressing properties of cell cycle inhibitors and suggested combined treatment with immunotherapy as a potential therapeutic approach."

Aurora B and Aurora C pools at two chromosomal regions collaboratively maintain chromosome alignment and prevent aneuploidy at the second meiotic division in mammalian oocytes. (PubMed, Front Cell Dev Biol) - "We found that kinetochore-microtubule attachments at single chromatids were corrected at both prometaphase II and metaphase II stages, but that single chromatids compared to paired chromatids were more prone to misalignments following treatment of oocytes with the Aurora B/C inhibitory drugs AZD1152 and GSK1070916. We conclude that the Aurora B/C pool at the inner central region stabilizes chromosome alignment during metaphase II arrest, while Aurora B/C localized at the kinetochore assist in re-establishing chromosome positioning at the metaphase plate if alignment is lost. Collaboratively these two pools prevent missegregation and aneuploidy at the second meiotic division in mammalian oocytes."
