Journal ArticleDOI
Molecular properties that influence the oral bioavailability of drug candidates.
Daniel F. Veber,Stephen R. Johnson,Hung-Yuan Cheng,Brian R. Smith,Keith W. Ward,Kenneth D. Kopple +5 more
TL;DR: Reduced molecular flexibility, as measured by the number of rotatable bonds, and low polar surface area or total hydrogen bond count are found to be important predictors of good oral bioavailability, independent of molecular weight.
Journal Article
Design and Characterization of Orally Active Arg-Gly-Asp Peptidomimetic Vitronectin Receptor Antagonist SB 265123 for Prevention of Bone Loss in Osteoporosis
Michael W. Lark,George B. Stroup,Shing Mei Hwang,Ian E. James,David J. Rieman,F. Drake,Jeremy N. Bradbeer,A. Mathur,Karl F. Erhard,Kenneth A. Newlander,Stephen T. Ross,Kevin L. Salyers,Brian R. Smith,William H. Miller,William F. Huffman,Maxine Gowen +15 more
TL;DR: This is the first report of an orally active alpha(v)beta(3) antagonist that is effective at inhibiting bone resorption when dosed in a pharmaceutically acceptable fashion and may provide a novel therapeutic agent for the treatment of postmenopausal osteoporosis.
Journal ArticleDOI
Antagonists of the calcium receptor I. Amino alcohol-based parathyroid hormone secretagogues
Robert W. Marquis,Lago Amparo M,James F. Callahan,Robert E. Lee Trout,M. Gowen,Eric G. Delmar,Bradford C. Van Wagenen,Sarah Logan,Scott Shimizu,John Fox,Edward F. Nemeth,Zheng Yang,Theresa J. Roethke,Brian R. Smith,Keith W. Ward,John C. Lee,Richard M. Keenan,Pradip K. Bhatnagar +17 more
TL;DR: Pharmacokinetic characterization of 38 in the rat revealed that this molecule had a large volume of distribution, which resulted in a prolonged systemic exposure, protracted increases in the plasma levels of PTH, and an overall lack of net bone formation effect in a rodent model of osteoporosis.
Journal ArticleDOI
Assessment of oral bioavailability enhancing approaches for SB-247083 using flow-through cell dissolution testing as one of the screens.
TL;DR: The reasonable correlation found between the FTC dissolution results and the oral bioavailability data demonstrate that FTC dissolution testing can be a valuable tool for aiding in salt (solid-state form) and formulation selection in the early stages of development of drug candidates.
Journal ArticleDOI
Phenylbutyrates as potent, orally bioavailable vitronectin receptor (integrin αvβ3) antagonists
William H. Miller,Manley Peter J,Russell D. Cousins,Karl F. Erhard,Dirk A. Heerding,Chet Kwon,Stephen T Ross,James Samanen,Dennis T. Takata,Irene N. Uzinskas,Catherine C.K. Yuan,R. Curtis Haltiwanger,Catherine J. Gress,M.W. Lark,Shing Mei Hwang,Ian E. James,David J. Rieman,Robert N. Willette,Tian Li Yue,Leonard M. Azzarano,Kevin L. Salyers,Brian R. Smith,Keith W. Ward,Kyung O. Johanson,William F. Huffman +24 more
TL;DR: A new series of phenylbutyrate derivatives, exemplified by 16, which have good potency and excellent oral bioavailability and are derived conceptually from opening of the seven-membered ring of SB-265123.
