Use Of Small Molecule Fanconi Anemia Pathway Inhibitors As Sensitizing Agents To Laromustine., Sam W. Marchant Jan 2021

Use Of Small Molecule Fanconi Anemia Pathway Inhibitors As Sensitizing Agents To Laromustine., Sam W. Marchant

Honors Theses

Laromustine is an experimental chemotherapeutic sulfonyl hydrazine prodrug shown in clinical trials to be effective against acute myeloid leukemia. The mechanism of action of laromustine involves interstrand crosslinking, via chloroethylation, and enzyme inhibition, caused by carbamoylation. The work described herein aims to investigate whether inhibition of the replication-dependent interstrand crosslink repair Fanconi Anemia pathway further sensitizes cells to laromustine. By measuring metabolic activity immediately after drug exposure, we find laromustine to be equally as cytotoxic towards Fanconi Anemia deficient and wild type cells. However, through clonogenic assays we show Fanconi Anemia mutations sensitize cells to laromustine’s anti-proliferative effect. Furthermore, we …


Assay Development For Isolation And Characterization Of Anticancer Properties Of Marine Fungi, Kyra Ricci Apr 2020

Assay Development For Isolation And Characterization Of Anticancer Properties Of Marine Fungi, Kyra Ricci

Honors Theses

Metabolites from fungi have potential use in the drug discovery process and have been used in the past to develop therapeutic agents for human use. Initial characterization of potential therapeutic properties of fungi is thus an important first step in identifying novel therapeutic compounds. In the present study, marine fungi were isolated from Myrtle Beach and assayed for anticancer properties using the soft agar colony formation assay in a 3D in vitro cellular environment. Many species were isolated from environmental samples, displaying unique morphologies and growth patterns. To optimize the soft agar assay in a six-well cell culture plate for …
