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, …

Dr. Cho-Chung from the NIH first thought to use halogenated cAMP derivatives as competitive inhibitors of cAMP to slow down cancer cell mitosis. While the iodine and bromine substituted versions showed very little therapeutic actions, 8-Chloro cAMP has been shown to have strong anti-cancer effects. This has been shown in the phase II clinical trials this drug has undergone. However, these trials have had issues with solubility and toxicity. The drug is similar to vitamin C and is excreted quickly. Scientists tried to overcome this by using a peristaltic pump to give patients a continuous dosage, but this proved too …


Toxicity And Cosmesis Outcomes For Single Fraction Intra-Operative Electron Radiotherapy (Ioert) For Breast Cancer, Monica Hanna, Robert Ash, Wesley Babaran, Michele M. Carpenter, Afshin Forouzannia, Jay K. Harness, Brian Kaltenecker, Snehith Maddula, Venita Williams, Lawrence Wagman Dec 2014

Background: Adjuvant radiation therapy is proven to reduce local recurrence in patients with early stage breast cancer. To reduce toxicity, improve geographic accuracy, and reduce treatment time, IOERT can be utilized as an alternative to external beam radiation therapy. The study’s objective was to determine the short term toxicity and cosmesis profile of single fraction IOERT given as definitive treatment in a community setting. Materials and Methods: From Mar 2012 to Jul 2014, 84 patients (3 bilateral), ages 45-91 y.o. with stage 0-II were treated with IOERT (Mobetron, IntraOp Medical, Sunnyvale, CA). A single 21 Gy fraction was administered to …


Effective Non-Viral Delivery Of Sirna To Acute Myeloid Leukemia Cells With Lipid-Substituted Polyethylenimines, Breanne Landry Jan 2012

Use of small interfering RNA (siRNA) is a promising approach for AML treatment as the siRNA molecule can be designed to specifically target proteins that contribute to aberrant cell proliferation in this disease. However, a clinical-relevant means of delivering siRNA molecules must be developed, as the cellular delivery of siRNA is problematic. Here, we report amphiphilic carriers combining a cationic polymer (2 kDa polyethyleneimine, PEI2) with lipophilic moieties to facilitate intracellular delivery of siRNA to AML cell lines. Complete binding of siRNA by the designed carriers was achieved at a polymer:siRNA ratio of ~0.5 and led to siRNA/polymer complexes of …
