BACKGROUND The clinical use of mefloquine (MQ) has declined due to dose-related neurological events. Next generation quinoline methanols (NGQMs) that do not accumulate in the central nervous system (CNS) to the same extent may have utility. In this study, CNS levels of NGQMs relative to MQ were measured and an early lead chemotype was identified for further(More)
UNLABELLED Acinetobacter baumannii is recognized as an emerging bacterial pathogen because of traits such as prolonged survival in a desiccated state, effective nosocomial transmission, and an inherent ability to acquire antibiotic resistance genes. A pressing need in the field of A. baumannii research is a suitable model strain that is representative of(More)
Ketotifen is known to exhibit antimalarial activity in mouse and monkey malaria models. However, the low plasma levels and short half life of the drug do not adequately explain its in vivo efficacy. We synthesized most of the known metabolites of ketotifen and evaluated their antimalarial activity and pharmacokinetics in mice. Norketotifen, the(More)
WR319691 has been shown to exhibit reasonable Plasmodium falciparum potency in vitro and exhibits reduced permeability across MDCK cell monolayers, which as part of our screening cascade led to further in vivo analysis. Single-dose pharmacokinetics was evaluated after an IV dose of 5 mg/kg in mice. Maximum bound and unbound brain levels of WR319691 were 97(More)
The use of mefloquine (MQ) for antimalarial treatment and prophylaxis has diminished largely in response to concerns about its neurologic side effects. An analog campaign designed to maintain the efficacy of MQ while minimizing blood–brain barrier (BBB) penetration has resulted in the synthesis of a prodrug with comparable-to-superior in vivo efficacy(More)
The effect of copper interconnects on memories is investigated. HSPICE simulations indicate a 30% improvement in the access time of a 2K×16 bit SRAM with copper interconnects compared to aluminum. Circuit techniques that utilize the transmission-line effect of copper interconnects for low-power operation are presented. HSPICE simulation results indicate(More)
