Kimmel Cancer Center Faculty Papers
Breast cancer brain metastasis (BCBM) typically results in an end-stage diagnosis and is hindered by a lack of brain-penetrant drugs. Tumors in the brain rely on the conversion of acetate to acetyl-CoA by the enzyme acetyl-CoA synthetase 2 (ACSS2), a key regulator of fatty acid synthesis and protein acetylation. Here, we used a computational pipeline to identify novel brain-penetrant ACSS2 inhibitors combining pharmacophore-based shape screen methodology with absorption, distribution, metabolism, and excretion (ADME) property predictions. We identified compounds AD-5584 and AD-8007 that were validated for specific binding affinity to ACSS2. Treatment of BCBM cells with AD-5584 and AD-8007 leads to …

Bcl2 Mediated Targeted Drug Delivery For The Treatment Of Kidney Fibrosis And Stomach Cancer, Humayra Afrin
Open Access Theses & Dissertations
Apoptosis, the programmed death of cells, is primarily regulated by a delicate balance between pro-apoptotic and anti-apoptotic signals. The Bcl-2 (B-cell lymphoma 2) family of proteins acts as anti-apoptotic agents, promoting cell survival. Dysregulation of these proteins is a common occurrence in conditions such as cancer and fibrosis, where overexpression of anti-apoptotic members can foster tumor cell survival and fibroblast activation. In this study, our aim was to explore the therapeutic potential of Bcl-2 inhibitors, both as a small molecule (specifically Navitoclax (Navi)), inhibitor and as Bcl-2 siRNA, for targeted treatment. Intravenous administration of Navi often leads to thrombocytopenia, necessitating …

Targeting Strategies To Optimize The Therapeutic Potential Of Gold Compounds Against Her2-Positive Breast Cancers, Afruja Ahad
Dissertations, Theses, and Capstone Projects
The overexpression of HER2 accounts for 20-30% of breast cancer tumors and not only serves as a marker for poor predictive clinical outcomes but also as a target for treatment. Antibody-drug conjugates (ADCs) combine the selectivity of monoclonal antibodies (mAbs) with the efficacy of chemotherapeutic drugs to provide targeted treatment without toxicity to normal tissue. Most of the ADCs currently in the clinic for cancer chemotherapy are based on complex organic molecules. In contrast, the conjugation of metallodrugs to mAbs has been overlooked when there is enormous potential in this area with the resurgence of metal-based drugs as prospective cancer …

Gene therapy is currently being studied as a treatment for a variety of indications, including cancer, infectious disease, and cardiovascular diseases, among others. While many of the early treatments in the field involved the use of viral delivery methods, various safety, ethical, and financial concerns limit the potential uses of this methodology. As such, more recent research has focused on developing non-viral delivery platforms to alleviate some of the issues inherent in viral delivery. Recently, the release of the COVID-19 vaccines from Pfizer and Moderna represents a promising use of non-viral delivery as both utilized a lipid-based delivery vector.

Long-Term Prescription Opioid Use, Cancer Stage, And Economic Burden Among Older Cancer Survivors With Non-Cancer Chronic Pain Conditions, Rudi Safarudin
Long-Term Prescription Opioid Use, Cancer Stage, And Economic Burden Among Older Cancer Survivors With Non-Cancer Chronic Pain Conditions, Rudi Safarudin
Graduate Theses, Dissertations, and Problem Reports
Opioids are commonly prescribed to treat pain conditions, which are highly prevalent among older adults (≥65 years). Recent evidence shows that opioids may have carcinogenic effects through immunosuppression and free-radical pathways, which could promote cancer growth. Two population-based studies have reported an association of opioid use with incident cancer. Many individuals with non-cancer chronic pain conditions (NCPCs) may use opioids for a long term. However, the association of long-term prescription opioid (LPO) use with cancer stage at diagnosis is still unknown. Furthermore, evidence suggests that individuals with cancer and pre-existing NCPCs may persistently use opioids, even in the absence of …

Identification Of Translesion Synthesis Inhibitors That Target Rev7/Rev3 Protein-Protein Interactions, Seema Patel
Identification Of Translesion Synthesis Inhibitors That Target Rev7/Rev3 Protein-Protein Interactions, Seema Patel
Honors Scholar Theses
Translesion synthesis (TLS) is a cellular mechanism utilized by cancer cells to tolerate DNA damage caused by chemotherapeutics, like cisplatin, by replicating past unrepaired lesions. This increases the rate of mutations, which leads to the emergence of drug-resistant cancer cells. Preliminary studies have shown that disrupting the protein-protein interactions (PPI) in the TLS heteroprotein complex increases cells’ sensitivity to first-line genotoxic chemotherapy, illustrating how inhibiting TLS assembly and function can significantly increase cancer cell death. These results underscore the therapeutic potential of targeting TLS PPI. Our current work in this area is focusing on inhibitors capable of disrupting the Rev7/Rev3 …
The Effects Of Paclitaxel On Cellular Migration And The Cytoskeleton, Ashley Salguero-Gonzalez
The Effects Of Paclitaxel On Cellular Migration And The Cytoskeleton, Ashley Salguero-Gonzalez
Thinking Matters Symposium
In a clinical setting, some patients are exposed to an anti-cancer chemotherapy agent, paclitaxel. Cancerous cells undergo rapid, continuous cell division without control. Chemotherapy treatments try to slow and stop the uncontrollable cell division cycles and eliminate cancerous cells in the process. Paclitaxel serves as a treatment for some types of cancers, including lung, melanoma, bladder, and esophageal. Because it targets the cytoskeleton, paclitaxel can also influence cell migration. This project utilizes a cellular migration assay and an immunohistochemistry assay to analyze the effects of paclitaxel on the movement of cells and on the cytoskeleton of neuroglia rat cells with …

Mediator Kinase Inhibitors For Breast Cancer Therapy, Xiaokai Ding
Theses and Dissertations
Breast cancers (BrCa) that overexpress oncogenic tyrosine kinase receptor HER2 are treated with HER2-targeting antibodies (such as trastuzumab) or small-molecule kinase inhibitors (such as lapatinib). However, most patients with metastatic HER2+ BrCa have intrinsic resistance and nearly all eventually become resistant to HER2-targeting therapy. Resistance to HER2-targeting drugs frequently involves transcriptional reprogramming associated with constitutive activation of different signaling pathways. We have investigated the role of CDK8/19 Mediator kinase, a regulator of transcriptional reprogramming, in the response of HER2+ BrCa to HER2-targeting drugs. Selective CDK8/19 inhibitors (senexin B and SNX631) showed synergistic interactions with lapatinib and trastuzumab in a panel …

Optimization Of The Structure Of Ttr Ligands For Half-Life Extension (Tlhe), Guanming Jiang
University of the Pacific Theses and Dissertations
Many potential therapeutic agents face challenges for their clinical development due to short circulation half-life. As a result, prolonging the half-life of therapeutic drugs in circulation while preserving their hydrophilicity and small size will be a key step toward more effective and safe pharmacological molecules. Our lab developed a new approach for enhancing the safety and efficacy of therapeutic agents. By endowing therapeutic agents with a hydrophilic small molecule (a derivative of the clinical candidate, AG10) which reversibly binds to the serum protein transthyretin (TTR), the half-life of the therapeutic agent should be extended by binding to the TTR in …

Background
In estimating the global burden of cancer, adolescents and young adults with cancer are often overlooked, despite being a distinct subgroup with unique epidemiology, clinical care needs, and societal impact. Comprehensive estimates of the global cancer burden in adolescents and young adults (aged 15–39 years) are lacking. To address this gap, we analysed results from the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2019, with a focus on the outcome of disability-adjusted life-years (DALYs), to inform global cancer control measures in adolescents and young adults.Methods

The Development Of Novel Cdk8 And Cdk19 Inhibitors And Degraders As Potential Anti-Cancer Agents, Li Zhang
The Development Of Novel Cdk8 And Cdk19 Inhibitors And Degraders As Potential Anti-Cancer Agents, Li Zhang
Theses and Dissertations
CDK8 and its homolog CDK19 are essential for transcription regulation and their dysregulation has been identified in numerous diseases, especially in cancers. CDK8 and CDK19 have been implicated in cancer development through their kinase activity and kinase independent functions. Despite the existing CDK8/19 inhibitors, there is still a need to develop novel CDK8/19 inhibitors with improved potency and PK profile. It is also necessary to develop CDK8/19 degraders that are able to eliminate the kinase-independent functions. Although two CDK8-degrading PROteolysis Activating Chimeras (PROTACs) have been reported, they have limited CDK8 degradation efficacy and no effect on CDK19. PROTACs with improved …

Pharmacy Faculty Articles and Research
Doxorubicin (Dox) is used for breast cancer, leukemia, and lymphoma treatment as an effective chemotherapeutic agent. However, Dox use is restricted due to inherent and acquired resistance and an 8-fold increase in the risk of potentially fatal cardiotoxicity. Hybrid cyclic-linear peptide [R5K]W7A and linear peptide R5KW7A were conjugated with Dox through a glutarate linker to afford [R5K]W7A-Dox and R5KW7A-Dox conjugates to generate Dox derivatives. Alternatively, [R5K]W7C was conjugated with Dox via a disulfide linker to generate [R5K]W7C–S–S-Dox conjugate, where S–S is a disulfide bond. Comparative antiproliferative assays between conjugates [R5K]W7A-Dox, [R5K]W7C–S–S-Dox, linear R5KW7A-Dox, the corresponding physical mixtures of the peptides, …

Design And Synthesis Of Macrocyclic Peptide Braf-Wt Dimerization Inhibitors For The Treatment Of Metastatic Melanoma, Chad Mulloy Beneker
Theses and Dissertations
In cases of metastatic melanoma, BRAF is frequently mutated to the V600E oncoprotein causing uncontrolled cell proliferation driven by the MAPK-ERK pathway. There are several BRAF inhibitors, such as vemurafenib, which are FDA approved, but patients treated with these Type-I kinase inhibitors frequently observe relapse under mutant RAS and BRAF-wt conditions due to paradoxical activation. The mechanism of this resistance occurs through binding of the inhibitor to BRAF-wt initiating conformational changes which leads to BRAF dimerization. Once in the dimerized state, the inhibited monomer induces allosteric transactivation of the second monomer. This drug-induced activation of BRAF in cells with mutant …
