Estimation of the metabolic stability of omipalisib in human liver microsomes employing an ultra-fast UPLC-MS/MS approach: in silico screening for structural alarms and metabolic lability. (PubMed, Anal Methods) - "OMP and duvelisib (internal standard) were evaluated using an SB-C18 column. In silico analysis indicates that slight structural modifications to the methoxy group or the pyridazine ring in the process of drug design may increase the safety profile and metabolic stability of new derivatives compared with those of OMP. The integrated in vitro/in silico approach provides a resource-efficient strategy for preliminary metabolic screening and advancing new therapeutic developments aimed at enhancing metabolic stability."

Modulating Metabolic Reprogramming By Phosphoglycerate Dehydrogenase (PHGDH) Inhibitors in Omipalisib-Refractory AML (ASH 2023) - "The OCI-AML3-R cell line was the most refractory one and showed cross-resistance to another PI3K/mTOR inhibitor dactolisib and multi-tyrosine kinase inhibitor dasatinib, in addition to omipalisib. Transcriptomic and metabolomic analyses revealed that OCI-AML3-R upregulated PPP and SSP, leading to increased nucleotide synthesis, which contribute cell growth and survival. Targeting PHGDH could significantly suppress omipalisib-refractory in AML and may have implications for future clinical trials."

Construction of a Myeloid Gene Signature Revealing Novel Therapeutic Targets for Myeloid Malignancies (ASH 2024) - "Omipalisib treatment significantly ameliorated features of myeloid malignancies including splenomegaly and leukocytosis which were both significantly reduced following 4 weeks of treatment, without affecting body weight.In summary, our MR analyses reveal that MPN predicts the risk of AML and enabled the construction of a novel myeloid signature which risk stratified AML patients across two different cohorts. We further demonstrate shared activation of PI3K/AKT/mTOR pathway across myeloid malignancies, with in vitro and in vivo data providing a rationale for therapeutic targeting of PI3K/AKT/mTOR pathway in these diseases."

Targeting serine metabolism vulnerability in omipalisib-resistant acute myeloid leukemia with phosphoglycerate dehydrogenase inhibitors. (PubMed, Biomed Pharmacother) - "Furthermore, we found that, like OCI-AML cells, the exportin 1 (XPO1) inhibitors selinexor and eltanexor significantly induced cell cycle arrest and reduced PHGDH expression in OCI-AML3-OR cells. Therefore, treatment with PHGDH inhibitors could be a therapeutic strategy for refractory AML to PI3K/mTOR inhibitors. Relevant clinical trials are warranted."

Changes in Melanoma Cell Morphology Following Inhibition of Cell Invasion by Third-Generation mTOR Kinase Inhibitors. (PubMed, Int J Mol Sci) - "The study used mTOR kinase inhibitors: Everolimus and Torkinib; dual PI3K/mTOR inhibitors BEZ-235 and Omipalisib; and the mTORC1/2 inhibitor OSI-027. These compounds were used both as monotherapy and in combination with the MEK1/2 inhibitor AS-703026...The morphology of cells also changed significantly: their thickness, volume, roughness, convexity of shape, and irregularity, which may be a good diagnostic and prognostic factor for the response to treatment. Our studies to date on the effect of three generations of mTOR kinase inhibitors on the inhibition of the invasion process, the activation of apoptosis, and the reduction in cell proliferation suggest that they may be an important target for anticancer therapy."

Downstream Signaling Mediators of CXCL6-driven Synthesis of Collagen in Human Fibroblasts (ATS 2025) - "Doxycycline was used to induce CXCL6 expression and secretion in BJ13 cells. A panel of specific pathway inhibitors were added to cells, including SR11302 (AP1), MK2206 (AKT), SB203850 (p38), SP600125 (JNK), PD184352 (MEK), FASUDIL (ROCK/RHO), SLV2436 (MNK1/2), Omipalisib (mTOR/PI3K), Torin (mTOR), and Reparixin (CXCR1/2)... We identified that CXCL6 induces collagen production through multiple pathways including mTOR, p38, JNK and MEK. Targeting a combination of these pathways may be a potential therapeutic direction for IPF treatment."

Navitoclax, a Bcl-2/xL Inhibitor, and YM155, a Survivin Inhibitor, in Combination with Carboplatin, Effectively Inhibit Ovarian Cancer Tumor Growth. (PubMed, Mol Cancer Ther) - "Initial results showed that omipalisib, verteporfin, CA3, mitoxantrone, navitoclax, venetoclax, and YM155 had significant single-drug activity in either the ALDHlo or both the ALDHlo/ALDHhi cell populations...In vivo, the combination of navitoclax/YM155/carboplatin decreased ovarian cancer metastasis, decreased the percentage of ALDHhi ovarian cancer cells in tumors, and increased survival when compared with carboplatin treatment alone in xenograft models. Our results suggest that the combination of navitoclax/YM155/carboplatin has promise as a therapy for treating ovarian cancer."

Combined Omipalisib and MAPK Inhibition Suppress PDAC Growth. (PubMed, Cancers (Basel)) - "In vivo oral administration of combined Omipalisib/Trametinib treatment was significantly more effective than Omipalisib/SHP099 in reducing implanted tumor growth, and the Omipalisib/Trametinib treatment more effectively reduced tumor progression and prolonged survival in an aggressive genetically engineered mouse model of PDAC than either Omipalisib or Trametinib alone. Altogether, our data support a rationale for a dual treatment strategy targeting both PI3K and MAPK pathways in pancreatic cancers."

A Novel 3D High-Throughput Phenotypic Drug Screening Pipeline to Identify Drugs with Repurposing Potential for the Treatment of Ovarian Cancer. (PubMed, Adv Healthc Mater) - "This approach has expedited the identification of promising candidates, such as rapamycin, which demonstrated limited activity as a monotherapy but synergized effectively with standard treatments like cisplatin and paclitaxel in vitro. In combination with platinum-based therapy, Rapamycin led to significant in vitro cytotoxicity and a marked reduction in tumor burden in a syngeneic in vivo model. This proof-of-concept study underscores the potential of drug repurposing to rapidly advance new treatments into clinical trials for OC, offering renewed hope for patients with advanced disease."
