Pharmaceutical Formulation For Poorly Water Soluble Camptothecin Analogues, Tiang-Xiang Xiang, Bradley D. Anderson Nov 2003

Pharmaceutical Formulation For Poorly Water Soluble Camptothecin Analogues, Tiang-Xiang Xiang, Bradley D. Anderson

Pharmaceutical Sciences Faculty Patents

The present invention provides a general method to retard the precipitation inception time for poorly water-soluble camptothecin analogues from a supersaturated solution by a chemical conversion approach via pH alteration. This method is successfully utilized to prepare stable parenteral formulations for silatecan 7-t-butyldimethylsilyl-10-hydroxycamptothecin (DB-67), a poorly water-soluble lipophilic camptothecin analogue, in aqueous solutions containing β-cyclodextrin sulfobutyl ether (SBE-CD) or other solubilizing agents. The formulations manufactured by this method are more simple and cost-effective, of higher doses and better quality in terms of manufacture loss and formulation stability, and can be free of organic solvents (e.g., DMSO or N-methyl-2-pyrrolidinone).

Maria Cekanova MS, RNDr, PhD

Distinct luteinizing hormone receptor (LHR) protein variants exist due to the posttranslational modifications. Besides ovaries, LHR immunoreactivity (LHRI) was also found in other tissues, such as the brain, fallopian tube, endometrium, trophoblast and resident tissue macrophages. The 3B5 mouse monoclonal antibody was raised against purified rat LHR. In rat, porcine and human ovaries, the 3B5 identified six distinct LHR bands migrating at approximately 92, 80, 68, 59, 52 and 48 kDa. Characteristic LHRI was detected in rat, human and porcine corpora lutea. During cellular differentiation, subcellular LHR distribution changed from none to granular cytoplasmic, perinuclear, surface, nuclear and no staining. …

Bifunctional Abietadiene Synthase: Mutual Structural Dependence Of The Active Sites For Protonation-Initiated And Ionization-Initiated Cyclizations, Reuben J. Peters, Ora A. Carter, Yan Zhang, Brian W. Matthews, Rodney B. Croteau Mar 2003

Bifunctional Abietadiene Synthase: Mutual Structural Dependence Of The Active Sites For Protonation-Initiated And Ionization-Initiated Cyclizations, Reuben J. Peters, Ora A. Carter, Yan Zhang, Brian W. Matthews, Rodney B. Croteau

Reuben J. Peters

Abietadiene synthase from grand fir catalyzes two sequential, mechanistically distinct cyclizations, of geranylgeranyl diphosphate and of copalyl diphosphate, in the formation of a mixture of abietadiene isomers as the committed step of diterpenoid resin acid biosynthesis. Each reaction is independently conducted at a separate active site residing in what were considered to be structurally distinct domains typical of terpene cyclases. Despite the presence of an unusual 250-residue N-terminal insertional element, a tandem pair of charged residues distal to the insertion was shown to form a functional part of the C-terminal active site. Because abietadiene synthase resembles the ancestral plant terpene …

Faculty Publications and Other Works -- Biochemistry, Cellular and Molecular Biology

Estrogens play an important role in the regulation of placental function, and 17-beta-estradiol (E2) production rises eighty fold during human pregnancy. Although term placenta has been found to specifically bind estrogens, cellular localization of estrogen receptor alpha (ER-alpha) in trophoblast remains unclear. We used western blot analysis and immunohistochemistry with h-151 and ID5 monoclonal antibodies to determine the expression and cellular localization of ER-alpha protein in human placentae and cultured trophoblast cells. Western blot analysis revealed a ~65 kDa ER-alpha band in MCF-7 breast carcinoma cells (positive control). A similar band was detected in five normal term placentae exhibiting strong …

Publications and Research

The delineation of dopamine dysfunction in the mentally ill has been a long-standing quest of biological psychiatry. The present study focuses on a recently recognized group of dopamine receptor- interacting proteins as possible novel sites of dysfunction in schizophrenic and bipolar patients. We demonstrate that the dorsolateral prefrontal cortex in schizophrenia and bipolar cases from the Stanley Foundation Neuropathology Consortium display significantly elevated levels of the D2 dopamine receptor desensitization regulatory protein, neuronal calcium sensor-1. These levels of neuronal calcium sensor-1 were not influenced by age, gender, hemisphere, cause of death, postmortem period, alcohol consumption, or antipsychotic and mood stabilizing …

Pharmaceutical Sciences Faculty Publications

Manganese (Mn) is an essential element and a neurotoxicant. Regulation of Mn movement across the blood–brain barrier (BBB) contributes to whether the brain Mn concentration is functional or toxic. In plasma, Mn associates with water, small molecular weight ligands and proteins. Mn speciation may influence the kinetics of its movement through the BBB. In the present work, the brain influx rates of 54Mn2+, 54Mn citrate and 54Mn transferrin (54Mn Tf) were determined using the in situ brain perfusion technique. The influx rates were compared to their predicted diffusion rates, which were determined from …


Clinical Issues Surrounding Once-Daily Aminoglycoside Dosing In Children, Chad A. Knoderer, Julie A. Everett, William F. Buss Jan 2003

Clinical Issues Surrounding Once-Daily Aminoglycoside Dosing In Children, Chad A. Knoderer, Julie A. Everett, William F. Buss

Scholarship and Professional Work – COPHS

Aminoglycoside antibiotics are first-line treatment for many infectious diseases in the pediatric population and are effective in adults. The traditional dosing interval in children is every 8–12 hours. Studies in adults reported equivalent efficacy and equal or less toxicity with once-daily regimens. Despite many studies in the adult population, this approach has yet to become standard practice in most pediatric hospitals. Reasons for lack of acceptance of this strategy in children include rapid aminoglycoside clearance, unknown duration of postantibiotic effect, safety concerns, and limited clinical and efficacy data.

During human pregnancy, the production of 17-beta-estradiol (E2) rises steadily to eighty fold at term, and placenta has been found to specifically bind estrogens. We have recently demonstrated the expression of estrogen receptor alpha (ER-alpha) protein in human placenta and its localization in villous cytotrophoblast (CT), vascular pericytes, and amniotic fibroblasts. In vitro, E2 stimulated development of large syncytiotrophoblast (ST) aggregates. In the present study we utilized ER-beta affinity purified polyclonal (N19:sc6820) and ER-alpha monoclonal (clone h-151) antibodies. Western blot analysis revealed a single ~52 kDa ER-beta band in chorionic villi (CV) protein extracts. In CV, strong cytoplasmic ER-beta immunoreactivity …


Toxicity Potential Of Aqueous Kava Extracts On Liver Function Tests In Rats, Ashwini K. Devkota Jan 2003

Toxicity Potential Of Aqueous Kava Extracts On Liver Function Tests In Rats, Ashwini K. Devkota

The Journal of Undergraduate Research

Kava, prepared as the traditional aqueous infusion, was tested in the rat for possible effects on liver function tests. Extracts were administered in dosages containing 200 or 500 mg of the active kavalactones per kg for two or four weeks. Sera were assayed for four enzymes that are markers of liver toxicity and liver homogenates for malondiadehyde formation that indicates changes in lipid peroxidation. The data showed that none of the enzymes, alanine aminotransferase, aspartate aminotransferase, alkaline phosphatase, and lactate dehydrogenase, nor malondialdehyde levels were elevated, in fact in some cases they were significantly reduced, suggesting the lack of a …

Equilibrative Nucleoside Transporter Family Members From Leishmania Donovani Are Electrogenic Proton Symporters, Alex Stein, Gayatri Vaseduvan, Nicola S. Carter, Buddy Ullman, Scott M. Landfear, Michael Kavanaugh

Biomedical and Pharmaceutical Sciences Faculty Publications

Leishmania donovani express two members of the equilibrative nucleoside transporter family; LdNT1 encoded by two closely related and linked genes, LdNT1.1 and LdNT1.2, that transport adenosine and pyrimidine nucleosides and LdNT2 that transports inosine and guanosine exclusively. LdNT1.1, LdNT1.2, and LdNT2 have been expressed in Xenopus laevis oocytes and found to be electrogenic in the presence of nucleoside ligands for which they mediate transport. Further analysis revealed that ligand uptake and transport currents through LdNT1-type transporters are proton-dependent. In addition to the flux of protons that is coupled to the transport reaction, LdNT1 transporters mediate a variable constitutive proton …
