Activity and kinetics of dissociation and transfer of amphotericin B from a novel delivery formAAPS PharmSci - Tập 1 - Trang 1-11 - 1999
Bradley Baas, katie Kindt, Angela Scott, Jessica Scott, Peter Mikulecky, Scott C. Hartsel
Recently it has been demonstrated that moderate heat treatment of Amphotericin B/deoxycholate solutions (HAmB-DOC) leads to a therapeutically interesting supramolecular rearrangement that can be observed by significant changes in light scattering, CD, and absorbance. In this study, we continue the investigation of the physical properties of this new form by evaluating the activity and kinetics of ...... hiện toàn bộ
Solvation and hydration characteristics of ibuprofen and acetylsalicylic acidAAPS PharmSci - Tập 6 - Trang 1-9 - 2015

Human proton/oligopeptide transporter (POT) genes: Identification of putative human genes using bioinformaticsAAPS PharmSci - Tập 2 - Trang 1-22 - 2000

Purpose: The proton-dependent oligopeptide transporters (POT) gene family currently consists of ∼70 cloned cDNAs derived from diverse organisms. In mammals, two genes encoding peptide transporters, PepT1 and PepT2 have been cloned in several species including humans, in addition to a rat histidine/peptide transporter (rPHT1). Because the Candida elegans genome contains five putative POT genes, we...... hiện toàn bộ
The composite solubility versus pH profile and its role in intestinal absorption predictionAAPS PharmSci - Tập 5 - Trang 1-15 - 2015
Barry A. Hendriksen, Manuel V. Sanchez Felix, Michael B. Bolger
The purpose of this study was to examine absorption of basic drugs as a function of the composite solubility curve and intestinally relevant pH by using a gastrointestinal tract (GIT) absorption simulation based on the advanced compartmental absorption and transit model. Absorption simulations were carried out for virtual monobasic drugs having a range of pKa, log D, and dose values as a function ...... hiện toàn bộ
