Developing Curcumin Analogues For Treating Breast Cancer, Tulasi Laxmi Nutalapati

Theses, Dissertations and Capstones

Breast cancer is still one of the most common types of cancer and one of the most common causes of cancer-related deaths in women around the world. Despite significant advances in early detection and treatment strategies, drug resistance, systemic toxicity, and poor outcomes in aggressive subtypes continue to limit the overall effectiveness of cancer therapy. Natural compounds have become promising anticancer agents because they can target many different things and are not very toxic. Curcumin has shown promise as an anticancer drug, but it cannot be used in the clinic because it does not absorb well, breaks down quickly, and …

Dual Role Of Triphala Extracts In Breast Cancer Therapy: Enhanced Paclitaxel Cytotoxicity By Ethanolic Extract And Cytoprotection By Aqueous Extract, Supamas Charucharana, Poonlarp Cheepsunthorn Ph.D., Chalisa L. Cheepsunthorn Ph.D.

Chulalongkorn Medical Journal

Background: Combining antioxidants with chemotherapy is an emerging strategy to reduce chemotoxicity in normal cells. Triphala (TPL), a polyphenol-rich Thai herbal formulation, has shown promise in enhancing chemotherapy efficacy, but its interaction with paclitaxel (PX) in breast cancer treatment remains underexplored.

Objective: This study evaluates the effects of aqueous (TPL-w) and ethanolic (TPL-a) TPL extracts combined with low-dose PX on breast cancer cells and non-tumorigenic mammary epithelial cells.

Methods: The bioactive components of TPL-w and TPL-a were identified using high-performance liquid chromatography (HPLC). Thiazolyl blue tetrazolium bromide (MTT) and chloromethyl 2′,7′-dichlorodihydrofluorescein diacetate (CM-H₂DCFDA) assays assessed cell viability and …

Antioxidant And Chemotherapeutic Synergy: Triphala Enhances Doxorubicin Cytotoxicity In Breast Cancer Cells And Reduces Toxicity In Non-Tumorigenic Cells, Supamas Charucharana, Poonlarp Cheepsunthorn Ph.D., Chalisa Louicharoen Cheepsunthorn Ph.D.

Chulalongkorn Medical Journal

Background: The combining of antioxidants with chemotherapy is increasingly explored to minimize toxicity in non-cancerous cells during breast cancer treatment. Triphala (TPL), a Thai herbal compound rich in antioxidants, shows potential as a complementary candidate for breast cancer chemotherapy.

Objective: This study investigated the combined effects of TPL and low-dose doxorubicin (DOX) on human breast cancer and non-tumorigenic mammary epithelial cells.

Methods: TPL’s bioactive compounds were analyzed via high-performance liquid chromatography (HPLC). Cell viability and reactive oxygen species (ROS) levels were assessed in breast cancer (MDA-MB-231, MCF-7) and epithelial (MCF-10A) cells using thiazolyl blue tetrazolium bromide (MTT) and chloromethyl 2′,7′-dichlorodihydrofluorescein …

Enhancing The Anticancer Effects Of Apiaceae Spice Phytochemicals., Jared Lee Scott

Electronic Theses and Dissertations

Breast cancer (BC) is a leading contributor to the death of women and is the most common type of cancer. Many chemotherapy drugs are developed from plants, and some plant extracts can exhibit significant anticancer activities while also having less toxic side effects. The Apiaceae plant family consists of several species that are used as culinarily spices which have demonstrated antioxidant, chemopreventive, and anticancer activities. The encapsulation of anticancer phytochemicals into naturally produced membrane-bound nanoparticles known as exosomes could improve their systemic distribution and efficacy. Exosomes are involved in cell-to-cell communication through the delivery of proteins, nucleic acids, and small …

Proteomic Characterization And Cytotoxic Potential Of Proteins From Cuscuta (Cuscuta Epithymum (L.) Crude Herbal Product Against Mcf-7 Human Breast Cancer Cell Line, Umaima Akhtar, Yamna Khurshid, Bishoy El-Aarag, Basir Syed, Ishtiaq A. Khan, Keykavous Parang, Aftab Ahmed

Pharmacy Faculty Articles and Research

Background

The burden of breast cancer, the second leading cause of death worldwide, is increasing at an alarming rate. Cuscuta, used in traditional medicine for different ailments, including cancer, is known for containing phytochemicals that exhibit anticancer activity; however, the bioactivities of proteins from this plant remain unexplored. This study aimed to screen the cytotoxic potential of proteins from the crude herbal product of Cuscuta epithymum(L.) (CE) harvested from the host plants Alhagi maurorum and Medicago sativa.

Methods

The proteins from CE were extracted using a salting-out method, followed by fractionation with a gel filtration chromatography column. Gel-free shotgun …

Isolation And Total Synthesis Of Sigma-2 Ligands From Marine Cyanobacteria, Andrea Hough

Electronic Theses and Dissertations

Cyanobacteria have been studied for over 50 years as a source of new antibiotics, antiviral, and anticancer drugs. The research described in this dissertation investigates marine cyanobacteria as a source of natural products with activity within the central nervous system and with cytotoxicity against breast cancer cells. Barbamide (1) is a known cyanobacterial metabolite that has been re-isolated from a variety of species and collection sites suggesting broad utility as a signaling molecule. Utilizing the psychoactive drug screening program, we screened barbamide for CNS activity and found that barbamide exhibited affinity for the kappa opioid receptor (KOR) and …

Phytochemical Analysis, Antioxidant And Anticancer Effects Of Clitoria Ternatae Extract On Breast T47d Cancer Cells, Ade Arsianti, Shahjahan Pasha Mahindra, Norma Nur Azizah, Ajeng Megawati Fajrin, Lince Dameria Nadapdap

Indonesian Journal of Medical Chemistry and Bioinformatics

Background: Breast cancer is one of the most common and deadly forms of cancer in the world. Cancer is a multi-factorial disease. Genetic factors, environment and lifestyle have a role in the development of cancer. One of the mechanisms of cancer development is when an imbalance between free radicals and antioxidants in the human body occurs. Uncontrolled and excessive amount of free radicals and cause cell damage and uncontrolled cell growth. Clitoria ternate is a plant that is often found in Asia and many of the benefits of this flower have been studied. This study aims to determine the phytochemical …

Paclitaxel Enhances Oncolytic Potential Of Herpes Simplex Virus Type-1 In Cancer Cells, Misagh Naderi

LSU Master's Theses

Taxanes are spindle poisons that bind to and stabilize microtubules resulting in mitotic arrest. Herpes simplex Typ-1 (HSV-1) virions utilize the microtubular network for intracellular transport during both virus entry and virus egress from infected cells. It has been reported previously that taxanes may synergize with oncolytic herpes simplex viruses in the treatment of experimental prostate and breast tumors in mice. Other reports have indicated that taxanes may inhibit viral replication in infected cells. In this study the previously characterized Oncolytic Herpes Simplex Virus type 1 (OSVP), which was constructed in Kousoulas lab was used in conjugation with paclitaxel (taxol) …
