We found that bcl-2 inhibitor (Obatoclax Mesylate) and TKI (Gefitinib) may have less sensitivity in our high-risk group ( P<0. 05), while some unconventional drugs (paclitaxe, dactinomycin, camptothecin, irinotecan and vinorelbine) may benefit in patients with higher FRGs expression (Figure J). In summary, we identified and validated 10 FRGs signature to well predict the prognosis and drug sensitivity of AML. Based on our findings, appropriate combination of new drugs at the time of treatment may achieve unexpected therapeutic outcomes, but still need to go through further verification.

The highest synergies were observed in the drug combinations Lapatinib with Thapsigargin and Lapatinib with Obatoclax Mesylate, both targeting epidermal growth factor receptor and affecting the apoptosis pathway. To further elaborate on the apoptosis cascade, we investigated other, more clinically relevant, apoptosis inducers and observed a strong synergistic effect while combining Venetoclax (BCL targeting) and AZD5991 (MCL1 targeting). Overall, we have identified via a high-throughput drug screening several new treatment strategies for GBM. Moreover, an exceptionally strong synergistic interaction was discovered between kinase targeting and apoptosis induction which is suitable for further clinical evaluation as multi-targeted combination therapy.

Further, in silico docking of phytochemicals present in C. lanceolatus with anti-apoptotic Bcl-2 protein endorsed apoptosis by its inhibition and thus corroborated the experimental findings. Obatoclax, a known inhibitor of Bcl-2 was used as a reference compounds.

We also found that obatoclax mesylate, NPK76-II-72-1, gemcitabine, TAK-715 are potential drugs for the treatment of refractory GBM based on drug sensitivity models of different immune subtypes. Therefore, we demonstrated that the immune subtypes of GBM have independent prognostic efficacy and can be used as clinical guidance for predicting the progression of GBM and drug sensitivity. Most importantly, this study is expected to provide a pathway for the development of effective drugs for treatment of refractory GBM.

Patients with low-PP scores were more sensitive to PD-L1, Cisplatin, Gefitinib, Obatoclax. Mesylate, Paclitaxel, Sorafenib and Vinorelbine (all p < 0.05). While, patients with low-PP scores were more sensitive to Axitinib and Camptothecin (all p < 0.05)...Our study revealed that phenotypic plasticity may be involved in the lymph node metastasis in LSCC through regulating cell responses and cell contraction. Evaluation of phenotypic plasticity will assist clinicians in making treatment strategies.

Furthermore, our national network of brain metastasis (RENACER) provided us with fresh neurosurgeries and, in a limited cohort of 10 surgeries with extended resections, we were able to identify invasive fronts with metastatic cells co-opting the vasculature. The use of obatoclax to target these cancer cells, which are the seeds of relapse post-surgery, confirmed that targeting vascular co-option could be a novel strategy to prevent metastasis in a clinically relevant situation.

However, the lowest binding energy (-10.1 kcal/mol) was offered by Friedelin against Bcl-2 protein when compared to other metabolites and the standard drug Obatoclax (-8.4 kcal/mol)...The ADMET profiling of selected compounds supported their in silico drug-likeness properties. Based on the computational analyses, the present study concluded that Friedelin of W. trilobata was found to be the potential inhibitor of the Bcl-2 protein, which merits attention for further in vitro and in vivo studies before clinical trials.

Treatments with BI.2536, Epothilone.B, Gemcitabine, Mitomycin.C, Obatoclax. Mesylate, and Sunitinib may profit high-risk patients...Our data highlight FRGs and CRGs in clinical practice and suggest ferroptosis and cuproptosis may be therapeutic targets for HCC patients. To validate the model's clinical efficacy, more HCC cases and prospective clinical assessments are needed.

DLST-altered cell lines were more sensitive to 7 approved drugs, among these obatoclax mesylate, a BCL2 inhibitor that reduces OXPHOS in human leukemia stem cells...We therefore conclude that, in addition to OXPHOS, protein kinases could be potential targets of therapy in the presence of DLST amplifications or high mRNA levels. The new drug candidates proposed here could serve in experimental testing on drug efficacy in knock-in cell lines and DLST-activated tumors.

Subsequently, the drug design specifications based on regulation ability, sensitivity and toxicity were employed as filter criteria for screening the potential drug combinations of Embelin and Obatoclax for MIBC, and Obatoclax, Entinostat and Imiquimod for ABC from their candidate drugs. In conclusion, we not only investigated the oncogenic mechanisms of MIBC and ABC, but also provided promising therapeutic options for MIBC and ABC, respectively.

Targeting the mTOR pathway with the dual mTORC1/2 inhibitor TAK-228 slows tumor growth and extends survival in mice bearing orthotopic xenografts. Combination therapy is well tolerated in mice bearing orthotopic xenografts of AT/RT, slows tumor growth, and extends median overall survival. This novel combination therapy could be added to standard upfront therapies or used as a salvage therapy for relapsed disease to improve outcomes in AT/RT.

We further found that compared to patients with low-risk score, patients with high-risk score had higher sensitivity to some drugs of targeting the immune microenvironment, including TGFβ receptor inhibitors SB525334 ( P <0.0001) and SB505124 ( P <0.0001) and immunomodulator Lenalidomide ( P =0.041), as well as NF-κB inhibitors Parthenolide ( P <0.0001) and TPCA-1 ( P <0.0001) and JAK inhibitors Ruxolitinib ( P =0.014) and TG101348 ( P =0.0053), accompanying with significantly lower IC50 values. In addition, another common chemotherapeutic drug Gemcitabine was also predicted to be more sensitive for patients with high-risk score ( P =0.047). Other targeted drugs such as Aurora kinase inhibitors VX-680 ( P <0.0001) and ZM-447439 ( P =0.014), Bcl-2 inhibitors Obatoclax Mesylate ( P =0.00036) and Navitoclax ( P <0.0001), and CDK inhibitors Roscovitine ( P =0.0012), AT-7519 ( P =0.0033), PHA-793887 ( P <0.0001) and THZ2-49 ( P =0.0053) also exhibited higher drug sensitivity for patients with high-risk score. Conclusions : PIM1 mutations play a vital role in patient risk stratification and provide novel insights into therapeutic decision making for DLBCL patients with high-risk score.

Many compounds with higher sensitivity for treating bladder cancer patients in the low-TNFRSF14-expression group were identified, with obatoclax being a potential drug most likely to treat patients in the low-TNFRSF14-expression group...We conducted a study to establish a 5-gene score model, providing reliable prediction for the outcome of bladder cancer patients and therapeutic drugs to individualize therapy. Our findings provide a signature that might help determine the optimal treatment for individual patients with bladder cancer.

The market pan-Bcl-2 inhibitor, obatoclax, was the lead framework compound for adopted structural modifications...Significant improvement was seen at the compound's cytotoxic activity. In conclusion, 8b is introduced as a promising anti-cancer lead candidate that worth future fine-tuned lead optimization and development studies while exploring its potentiality through in-vivo preclinical investigation.

We further revealed that, depending on the cell context, Obatoclax suppresses WNT/β-catenin signaling in HCT 116 cells likely via inducing β-catenin destabilization, or by downregulating LEF1 in DLD-1 cells. Collectively, we for the first time define survivin downregulation as a novel, pro-apoptotic mechanism of Obatoclax as a consequence of Obatocalx acting as an antagonist to WNT/β-catenin signaling.

Our results indicate that obatoclax reduces cell viability in AML cells, regardless of their sensitivity to venetoclax, suggesting that pan-BCL2 inhibition by this drug may overcome intrinsic resistance in AML cellular models. These findings provide pharmacological tools for direct additional investigation of molecular mechanisms involved in intrinsic resistance to venetoclax and highlighted obatoclax as a potential therapeutic option in this context.

The expressions of E-Cadherin(P＜0.01)and p53(P＜0.01) protein were increased significantly compared with GEM group. Under hypoxia condition, OBX combined with a low-dose of GEM can significantly inhibit the growth, migration and invasion of breast cancer cells, and enhance the pro-apoptotic effect of GEM, but the specific mechanism needs further study.

Proteasome inhibitors, bortezomib (BTZ), and carfilzomib (CFZ) are approved drugs for hematological malignancies, but lack anticancer activities against most solid tumors. In nude mice bearing in SCLC H82 xenografts, both BTZ-OBX, and CFZ-OBX combinations exhibited remarkable antitumor activities against SCLC tumors evidenced by significant reduction of tumor size and the proliferation marker Ki-67 signals in tumor tissues as compared with single agent alone. Thus, proteasome inhibitor-OBX combinations are worth immediate assessments for SCLC in clinical settings.

Furthermore, RBCm-OM/PLGA nanoparticles exerted stronger antitumor efficacy in vivo against lung cancer progression with superior safety. Therefore, RBCm-OM/PLGA nanoparticles provided new potential for lung cancer therapy with the improved safety and therapeutic effect.

We have previously demonstrated that Sapanisertib combines synergistically with cisplatin to extend survival in AT/RT. Combination treatment was well tolerated and more than doubled median survival. Our data supports a new clinical trial combining Sapinisertib with Obatoclax to extend survival in AT/RT.

Molecular docking studies showed that both molecules bind more tightly with the BH3 domain of Bcl-2 proteins compared to obatoclax (a pan-Bcl-2 inhibitor)...This small molecule-mediated mitochondrial damage induced remarkably high cervical cancer cell death. These unique small molecules can be further explored as chemical biology tools and next-generation organelle-targeted anticancer therapy.
