Great Expectations: Phosph(On)Ate Prodrugs In Drug Design—Opportunities And Limitations, Victoria Yan Dec 2020

Great Expectations: Phosph(On)Ate Prodrugs In Drug Design—Opportunities And Limitations, Victoria Yan

Dissertations & Theses (Open Access)

Phosphate and phosphonates are chemical moieties with historical precedence in anticancer and antiviral nucleotide analogues. Synchronous to modern efforts identifying novel therapeutic targets in cancer, such chemical moieties are being investigated in the design of novel inhibitors with antineoplastic potential. A central challenge to the delivery of phosph(on)ate-containing drugs is their anionic character at physiological pH, which portends poor membrane permeability. This limitation has been successfully overcome through the use of prodrugs. When attached to the phosph(on)ate moiety, prodrugs mask the negative charge and easily enable cell permeability. Upon cellular entry, the promoieties are enzymatically or environmentally cleaved to unveil …


Remdesivir-Warfarin Interaction: A Case Report, Kayihura Manigaba, Josh Hawks, Marie Kima Nov 2020

Remdesivir-Warfarin Interaction: A Case Report, Kayihura Manigaba, Josh Hawks, Marie Kima

HCA Healthcare Journal of Medicine

A greater than 65-year-old Caucasian woman receiving long-term anticoagulation with warfarin for atrial fibrillation experienced a sudden rise in an international normalized ratio (INR) after she was started on remdesivir for management of 2019 Novel Coronavirus (COVID-19). Patient INR was maintained within the target therapeutic range of 2–3 with a warfarin dose of 11 mg/week before starting remdesivir. After 2 days of remdesivir therapy, the patient’s INR increased significantly and remained elevated during the 5 day course of remdesivir therapy. Patient required an interruption of her warfarin therapy for 7 days, and her INR did not return to the targeted …

Currently, a global pandemic era of public health concerns is going on with the Coronavirus Disease 2019 (COVID-19), which is caused by severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2). The first case of COVID-19 was reported from Wuhan’s Huanan seafood market in China late December 2019. Bats, pangolins, and snakes have been nominated as salient carriers of the virus. Thanks to its high pathogenicity, it can cause severe respiratory infections. Fever, dry cough, sore throat, pneumonia, septic shock, and ground-glass opacities are the foremost clinical manifestations of COVID-19. Immunocompromised patients are at high risk for COVID-19 infection and may lead to …


Foundational Research And Nih Funding Enabling Emergency Use Authorization Of Remdesivir For Covid-19, Ekaterina Galkina Cleary, Matthew J. Jackson, Zoë Folchman-Wagner, Fred D. Ledley Jul 2020

Emergency Use Authorization for remdesivir months after discovery of COVID-19 is unprecedented. Typically, decades of research and public-sector funding are required to establish the mature body of foundational research requisite for efficient, targeted drug discovery and development. This work quantifies the body of research related to remdesivir’s biological target, RNA-dependent RNA polymerase (RdRp), or parent chemical structure, nucleoside analogs (NcAn), through 2019, as well as NIH funding for this research 2000–2019. There were 6,567 RdRp-related publications in PubMed, including 1,263 with NIH support, and 11,073 NcAn-related publications, including 2,319 with NIH support. NIH support for RdRp research comprised 2,203 Project …


Comparative Antiviral Activity Of Remdesivir And Anti-Hiv Nucleoside Analogs Against Human Coronavirus 229e (Hcov-229e), Keykavous Parang, Naglaa Salem El-Sayed, Assad J. Kazeminy, Rakesh Tiwari May 2020

Remdesivir is a nucleotide prodrug that is currently undergoing extensive clinical trials for the treatment of COVID-19. The prodrug is metabolized to its active triphosphate form and interferes with the action of RNA-dependent RNA polymerase of SARS-COV-2. Herein, we report the antiviral activity of remdesivir against human coronavirus 229E (HCoV-229E) compared to known anti-HIV agents. These agents included tenofovir (TFV), 4′-ethynyl-2-fluoro-2′-deoxyadenosine (EFdA), alovudine (FLT), lamivudine (3TC), and emtricitabine (FTC), known as nucleoside reverse-transcriptase inhibitors (NRTIs), and a number of 5′-O-fatty acylated anti-HIV nucleoside conjugates. The anti-HIV nucleosides interfere with HIV RNA-dependent DNA polymerase and/or act as chain terminators. …
