Preclinical Evaluation Of An Unconventional Ruthenium‐Gold‐ Based Chemotherapeutic: Rance‐1, In Clear Cell Renal Cell Carcinoma, Benelita Elie, Karen Hubbard, Yuriy Pechenyy, Buddhadev Layek, Swayam Prabha, Maria Contel

Publications and Research

Background: There are few effective treatments for patients with advanced clear cell renal cell carcinoma (CCRCC). Recent findings indicate that ruthenium‐gold containing compounds exhibit significant antitumor efficacy against CCRCC in vitro affecting cell viability as well as angiogenesis and markers driving those 2 phenomena. However, no in vivo preclinical evaluation of this class of compounds has been reported.

Methods: Following the dose‐finding pharmacokinetic determination, NOD. CB17‐Prkdc SCID/J mice bearing xenograft CCRCC Caki‐1 tumors were treated in an intervention trial for 21 days at 10 mg/kg/72h of RANCE‐1. At the end of the trial, tumor samples were analyzed for histopathological and …

Pharmacokinetics Of Ketamine At Dissociative Doses In An Adult Patient With Refractory Status Asthmaticus Receiving Extracorporeal Membrane Oxygenation Therapy., Edwin Lam, Ankit K. Rochani, Gagan Kaushal, Brandi N. Thoma, Julian Tanjuakio, Frances Mae West, Hitoshi Hirose

Department of Pharmacology and Experimental Therapeutics Faculty Papers

PURPOSE: First-line management of severe asthma exacerbations include the use of inhaled short-acting β-agonists, anticholinergics, and systemic corticosteroids. Continuous intravenous ketamine given at dissociative doses may be a pharmacologic option in patients who are intubated with life-threatening severe bronchospasm unresponsive to standard therapy. We describe the case of a 44-year-old man admitted to the intensive care unit for status asthmaticus requiring intubation and mechanical ventilation.

METHODS: The patient developed severe refractory hypercapnic respiratory failure necessitating additional respiratory support with veno-venous extracorporeal membrane oxygenation (ECMO) therapy. Ketamine treatment was initiated at 0.5 mg/kg/h continuous infusion on the day of admission for …

Development Of Topical Oil/Peg Creams Of Voriconazole, Abhishek Shivashankar Shettar

Electronic Theses and Dissertations

Voriconazole (VRC) was selected as a model drug for preparation of Oil/PEG cream consisting of PEG 2000, PEG 400 and propylene glycol after performing drug-excipient compatibility studies. Twin screw processor with a 10 mm co-rotating twin screw configuration was used for preparation of oil/PEG creams. Creams prepared using twin-screw processor were characterized for the following: Differential Scanning Calorimetry (DSC), pH, Solvent activity (as)), viscosity, drug content uniformity, in vitro drug release testing (IVRT) and in vitro permeation testing (IVPT) using human cadaver skin. Creams are heterogenous biphasic semi-solid preparations consisting of oil and aqueous phases, wherein one phase is dispersed …

Effect Of Sulfobutyl Ether Β-Cyclodextrins On Oral And Dermal Pharmacokinetics Of Drugs, Vijay Kumar Shankar

Electronic Theses and Dissertations

Silymarin is an extract of Milk Thistle, major constituents are taxifolin, silychristin, silydianin, silybin A, silybin B, isosilybin A and isosilybin B. The in vitro, preclinical and clinical studies have demonstrated silymarin possesses hepatoprotective, anticancer, hypocholesterolemic, cardioprotective effect and dermatological beneficial effect (treatment of UV induced erythema, melanoma, non-melanoma skin cancer, rosacea, melasma, vitiligo and psoriasis) both individually and collectively. Solubility enhancement of silymarin constituent is utmost important to increase bioavailability and to improve drug developability property. The solubility of silymarin in water was enhanced by SBE-β-CD by conventional and heating method, heating method was found to be more efficient …

Unraveling Anticancer Activity And Pharmacokinetics Of Dihydroartemisinin Dimer Oxime, Lu Dai

Electronic Theses and Dissertations

Artemisinin is currently used as an antimalaria drug. Studies have shown its monomeric form exhibited promising anticancer effects by inhibiting the proliferation, inducing apoptosis, and increasing oxidative stress of tumor cells. Recently, several dimeric forms of artemisinin have been synthesized with more potent anticancer activity. In this study, nine dihydroartemisinin dimers with diversely functionalized linkers exhibited similar cytotoxicity against human breast adenocarcinoma MDA-MB-231 in vitro. Among these nine DHA dimers, DHA dimer oxime was selected for further anticancer activity and pharmacokinetic study. Our preliminary study shothat DHA dimer oxime displayed more than a 10-fold increase of antiproliferation effect over its …

The Role Of Aryl Hydrocarbon Receptor (Ahr) In Drug-Drug Interaction And The Expression Of Ahr In Pichia Pastoris, Yujuan Zheng

University of the Pacific Theses and Dissertations

The aryl hydrocarbon receptor is a ligand-activated transcription factor that is involved in many important functions in the body. To study the role and function of AHR, an abundant amount of in vitro expressed and purified protein is needed. A baculovirus insect expression system is commonly employed to express AHR, however, there are several drawbacks with this method, such as mutation potential and high cost. A better in overexpression system is needed and we hypothesize that Pichia pastoris, a yeast expression system, could stably express AHR and ARNT (aryl hydrocarbon receptor nuclear translocator) in sufficient amount with reasonable cost. Codon …
