Metabolic-cell-death gene trio predicts survival and cuproptosis sensitivity in colorectal cancer. (PubMed, J Gastrointest Oncol) - "High-risk tumors were enriched for extracellular matrix (ECM)-receptor-interaction pathways, displayed abundant myeloid-derived suppressor cell (MDSC) infiltration and were more vulnerable to AZD8186, AZ960 and JAK inhibitors...We report the first MCD-derived prognostic platform for CRC that simultaneously predicts survival and therapeutic response. Targeting CDKN2A-enhanced cuproptosis represents a promising metabolic-precision strategy for high-risk patients."

Discovery of a triple-site inhibitor targeting bacterial methionyl-tRNA synthetase through combined drug repurposing screening and generative AI-assisted optimization. (PubMed, Nucleic Acids Res) - "In this study, a drug repurposing screen of a kinase inhibitor library identified AZD8186, a clinically investigated PI3Kβ modulator, as a promising inhibitor of Staphylococcus aureus MetRS (SaMetRS)...Importantly, MRS-9 selectively inhibited type 1 MetRS enzymes, while minimally affecting the tested type 2 MetRSs, including the human MetRS, thereby reducing potential adverse effects. This study reveals a novel triple-site inhibitory mechanism targeting MetRS and highlights an integrated strategy that combines knowledge-directed and AI-guided approaches in drug design."

Use of metabolic imaging to monitor heterogeneity of tumour response following therapeutic mTORC1/2 pathway inhibition. (PubMed, Dis Model Mech) - "An integrated multi-modal imaging workflow was developed to assess the heterogeneity of AZD2014 (mTORC1/2 inhibitor) response in a PTEN-null renal cancer model...Increasing PI3K-AKT inhibition by combining with AZD8186 (PI3Kβ inhibitor) further decreased the control-like metabolic signature, showing PI3K-dependent resistance. This demonstrates that MSI-based workflows yield novel insights into the pharmacodynamic effects of mTORC1/2 inhibition in tumours, which classical biomarkers do not resolve. Coupling these workflows with spatial-omics approaches can deliver greater insights into heterogeneity of treatment response."

Tumor adaptation to PI3K inhibition and its stability increases as a function of time and is overcome by combined inhibiting Bcl2 family proteins (EORTC-NCI-AACR 2024) - "Materials &Methods; Cell culture with cell lines BT474, SKbR3, MCF7 and breast PDXs, drug treatment with PI3K inhibitors BYL-719 (1uM) and AZD8186 (250nM), bulk RNA sequencing. Conclusions; The data suggests that induction of adaptive resistance is in part responsible for the continued persistence of tumor masses after the initial response to targeted therapy but also makes them more sensitive towards Mcl1/Bcl2 inhibitors due to upregulation of an anti-apoptotic program. This can be exploited in a pulsatile combination treatment strategy to circumvent chronic adaptive resistance and improve therapeutic outcomes in patients."

Dual inhibition of MEK and PI3Kβ/δ-a potential therapeutic strategy in PTEN-wild-type docetaxel-resistant metastatic prostate cancer.

Our findings on the activity of selumetinib+AZD8186 in PTEN-wt cells and in docetaxel-resistant xenograft mice provide an excellent rationale for a novel therapeutic strategy for PTEN-wt mCRPC patients resistant to docetaxel, in whom, unlike PTEN-loss patients, a clinical benefit of treatment with single-agent PI3K and AKT inhibitors has not been demonstrated. A phase I-II trial of this promising combination is warranted."

β1 integrin mediates unresponsiveness to PI3Kα inhibition for radiochemosensitization of 3D HNSCC models.
