1. The metabolism of stobadine, a gamma-carboline antiarrhythmic and cardioprotective agent, was investigated in vitro using fortified rat liver microsomal preparations. 2. Two metabolic products, N-desmethyl stobadine and stobadine N-oxide were isolated and identified by means of t.l.c.,g.l.c. -mass spectrometry, n.m.r. spectrometry and comparison with(More)
To speed drug discovery, we developed an approach for identification of individual peptides with a desired biological activity from a library containing millions of peptides. The approach uses sequential orthogonal release of chemically synthesized peptides from insoluble beads, followed by testing in solution. In this system, each bead within a library of(More)
The synthesis and likely conformational structure of rigid spirocyclic bislactams and lactam-lactones derived from pyroglutamic acid, and their suitability as lead structures for applications in drug development programmes using cheminformatic analysis, has been investgated.
BACKGROUND Amyloid beta (Aβ) oligomers play a critical role in the pathogenesis of Alzheimer's disease (AD) and represent a promising target for drug development. Tramiprosate is a small-molecule Aβ anti-aggregation agent that was evaluated in phase III clinical trials for AD but did not meet the primary efficacy endpoints; however, a pre-specified subgroup(More)
BACKGROUND ALZ-801 is an orally available, valine-conjugated prodrug of tramiprosate. Tramiprosate, the active agent, is a small-molecule β-amyloid (Aβ) anti-oligomer and aggregation inhibitor that was evaluated extensively in preclinical and clinical investigations for the treatment of Alzheimer's disease (AD). Tramiprosate has been found to inhibit(More)
