Mechanistic Investigation Of C—C Bond Activation Of Phosphaalkynes With Pt(0) Complexes, Roberto M. Escobar, Abdurrahman C. Ateşin, Christian Müller, William D. Jones, Tülay Ateşin
Research Symposium
Carbon–carbon (C–C) bond activation has gained increased attention as a direct method for the synthesis of pharmaceuticals. Due to the thermodynamic stability and kinetic inaccessibility of the C–C bonds, however, activation of C–C bonds by homogeneous transition-metal catalysts under mild homogeneous conditions is still a challenge. Most of the systems in which the activation occurs either have aromatization or relief of ring strain as the primary driving force. The activation of unstrained C–C bonds of phosphaalkynes does not have this advantage. This study employs Density Functional Theory (DFT) calculations to elucidate Pt(0)-mediated C–CP bond activation mechanisms in phosphaalkynes. Investigating the …

Research Symposium
Background: CARF (Collaborator of ARF)/CDKN2AIP is an essential protein, first cloned as a binding partner of ARF. It was subsequently shown to interact with p53, HDM2 proteins and regulate growth arrest and apoptosis by its multimodal mechanism of action. Over-expression of CARF caused senescence like growth arrest of cells, its knock-down triggered apoptosis. Intriguingly, malignantly transformed cells showed high level of CARF expression. Based on these findings, we hypothesized that level of CARF expression may be a key determinant of cell proliferation fates; where an increase in its levels causes growth arrest/senescence, but beyond a threshold it activates carcinogenesis.

Research Symposium
Background: Cancer is one of the most common destructive diseases and the second leading cause of death in humans. Among cancer, cervical cancer is the second most common malignancy among women globally. Thus, there is a continuous need to search for chemotherapeutic chemicals or naturally occurring drugs to resolve this global health problem. Piperine (1-piperoylpeperdine) is present in the fruits of black pepper (Piper nigrum Linn.) and long pepper (Piper longum Linn.). It possesses several pharmacological properties and in the present study we have evaluated its anti-cancer potential on human cervical adenocarcinoma (HeLa) cells.
Methods: The anti-proliferative effect …

Research Symposium
Background: To guide the treatment with monoclonal antibodies (MAbs) against the epidermal growth factor receptor (EGFR) of metastatic colorectal cancer (mCRC), the FDA recommends prior companion molecular diagnosis (CMDx). It initially recommended screening for mutations in exon 2 of the KRAS gene, and most recently to extend to screening to exons 2, 3, and 4 of KRAS and 2, 3, and 4 of NRAS genes; furthermore, to evaluate the BRAF exon 15 mutation status (including V600E). To date, no studies have been done to compare the cost-benefit of these different CMDXs.
Methods: We have compared the cost of treatment without …

Background: Biochanin A, an isoflavone that is mainly present in red clover, has potent chemopreventive properties against many cancers. Ovarian carcinoma is fifth most common and deadliest gynaecological malignancy that causes the highest mortality in females worldwide. Hence a substantial need for new therapies for combating this gynaecological malignancy arises.
Methods: The present study aimed to investigate anti-cancerous potentials of biochanin A on cultured human ovarian carcinoma PA-1 cells through the cell viability assay, cellular apoptosis, disruption of mitochondrial membrane potential (MMP), involvement of ROS, cell cycle kinetics, and expression of apoptosis-related genes namely, p53, Bax, Bcl-2, Noxa and Puma. …

Worldwide female breast cancer is the most commonly diagnosed cancer, with an estimated 2.3 million new cases in 2020, reason for the need of targeted therapies that can maximize treatment success and minimize toxicity. Nanoparticles of gold (AuNps) exhibit cytotoxic properties against certain types of cancer cell lines. Nanofibers have been use in the drug delivery systems due to its degradability and high surface area. We proposed a membrane with nanometric fibers using polivinilic alcohol (PVA) and chitosan (Qts) loaded with AuNps and Doxorubicin (Doxo) with the purpose of diminish tumor regression.
PVA-Qts membrane was develop with electrospinning, the injection, …

Research Symposium
Epithelial Growth Factor (EGF) is the primary source in regeneration and stimulation of essential fibroblasts cells commonly found in epithelium. Studies have shown that snake venom components are becoming a growing factor in treating illnesses such as cancer, muscular dystrophy, chronic pain, blood pressure, blood clotting, etc. EGF in human cells contains a promising quaternary structure that can bind to snake venom metalloproteinases, proposing a means of activating biochemical responses through protein-protein interactions to regulate unwanted cellular functions. This supports promising research in achieving a greater understanding of regulation along cellular pathways through ligands, increasing the likelihood of targeting unwanted …

Research Symposium
Background: The misuse of opioids, including prescription opioids, heroin, and fentanyl, has reached epidemic proportions in the US, resulting in more than 68,000 overdose deaths in 2020, and a total of $78.5 billion a year of economic burden. In response to this crisis, the US Department of Health and Human Services (DHHS) released a strategic plan to combat opioid abuse and misuse, recommending a multidisciplinary approach, including the inclusion of pharmacists in the efforts. The aim of this study is to examine pharmacists’ perception of their role in the provision of medication for opioid use disorders (MOUD) in addition to …

Research Symposium
Background: Hypoxia, a suboptimal level of oxygen, evokes stress response in cells and activated hypoxia signaling has been largely established as a pro-metastasis and pro-angiogenic factor for tumor cells. On the other hand, age-related neurodegenerative disorders are characterized by hypoxic environment, accumulation of molecular garbage and induction of premature senescence. Several recent studies have reported anti-stress impact of the intermittent induction of hypoxia signaling in these cells.
Methods: Screening of a phytochemical library using Hypoxia Responsive Element (HRE) driven luciferase as a reporter was carried out to identify hypoxia-modulating phytochemicals. Activation of HIF-1a (master regulator of hypoxia signaling) was validated …
