Development Of Novel Alkaloid Derivatives For The Treatment Of Chronic Myeloid Leukemia, Lindsay Michelle Renn
Development Of Novel Alkaloid Derivatives For The Treatment Of Chronic Myeloid Leukemia, Lindsay Michelle Renn
Theses and Dissertations
The majority of chronic myeloid leukemia (CML) patients can be treated with and respond to imatinib mesylate (Gleevec). Imatinib is known to inhibit BCR-ABLl kinase activity, and is effective for the treatment of the majority of CML patients. Multiple mutations have been found in patients resistant to imatinib treatment, including many located in the BCR-ABLl tyrosine kinase domain (e.g. E255K and T315I). Matrine is a bioactive alkaloid from Sophora flavescens and has been shown to inhibit several types of cancers and is used in Chinese medicine. The goal of this study is to develop new matrine derivatives that inhibit growth …
Cytotoxic And Antimicrobial Effects Of Silver-Containing Surfaces, Sarah Goderecci
Cytotoxic And Antimicrobial Effects Of Silver-Containing Surfaces, Sarah Goderecci
Theses and Dissertations
This study examines applications of sputtered silver coatings as alternatives to traditional antibiotic treatments. Given the increase in reports of antibiotic-resistant bacteria, new treatments and coatings for in-dwelling medical devices such as catheters and orthopedic implants are necessary. Silver oxide films were deposited onto Ti surfaces to examine the efficacy of such coatings against a variety of bacterial species both in vitro and in vivo. Bacterial growth studies showed that coatings exhibited antimicrobial activity against a range of bacterial species acting either in a bacteriostatic or bactericidal mechanism, depending on the target. Limited toxicity to in vitro mammalian cells was …
