“Previously we described a series of 5-acylaminobenzophenones

with considerable antimalarial activity. Unfortunately, most compounds also displayed high cytotoxicity resulting in low selectivity towards malaria parasites. Through the replacement GW786034 manufacturer of the 5-acylamino moiety by simple chlorine and further modifications of the 2-acylamino residue we could obtain inhibitors with improved selectivity towards malaria parasites combined with an acceptable reduction of antimalarial activity.

“Objective: Aclidinium bromide is a novel antimuscarinic being developed for the treatment of chronic obstructive pulmonary disease. The objective of this Phase I study

was to determine the maximum tolerated dose (MTD) as well as the tolerability, safety and pharmacokinetics of aclidinium in healthy subjects. Materials and methods: 16 healthy Subjects were randomized to receive 5 single ascending doses of aclidinium 600 – 6,000 mu g or placebo inhaled via dry powder inhaler, with 7 day washouts. Anti-infection Compound Library solubility dmso Safety measurements included adverse events (AEs), physical examination, vital signs, pupillometry examination, clinical laboratory tests, and 12-lead electrocardiogram. Pharmacokinetic parameters of aclidinium and its metabolites were assessed. Results: The incidence of AEs was comparable between aclidinium and placebo at all doses. Most AEs were mild to moderate with no dose-related or anticholinergic/cardiac AEs. At doses >= 2,400 mu g. only 13 AEs were considered treatment related. Aclidinium (600 – 6,000 mu g) did not produce function-limiting or severe AEs in >= 50% of subjects; hence, the prospectively-defined MTD was not established. Aclidiniurn was rapidly converted in https://www.selleckchem.com/products/Vorinostat-saha.html plasma into alcohol and carboxylic acid metabolites, and was no longer detectable after 3 hours post-dose for all doses. At lower doses, aclidinium was quantifiable only up to 1 hour

post-dose in the majority Of Subjects. Maximum plasma concentrations for aclidinium were reached within 5 – 7 minutes (all doses) and declined rapidly. Mean elimination half-lives of aclidinium > 2,400 mu g were approximately 1 hour. AUC and C(max) increased proportionately up to 4,800 mu g. Conclusions: Aclidiniurn appears to be safe and well tolerated in single doses of 600 – 6,000 mu g.”
