A new class of antimuscarinic drugs was designed and synthesized. The compounds are "soft" quaternary ammonium esters in which there is only one carbon atom separating the ester oxygen and the quaternary head. The compounds are potent anticholinergics when derived

Four new soft anticholinergic agents based on tropyl alpha-phenylcyclopentylacetate, 15a, 15b, 18a, and 18b, were designed and synthesized. Receptor binding studies on the cloned human muscarinic receptors indicated that the new soft anticholinergic agents possessed moderate potency as pKi ranged

Ester hydrolysis represents an important biotransformation pathway for various parasympatholytic agents. Cleavage of the ciclotropium ester bond results in the formation of alpha-phenylciclopentylacetic acid (PCA). The relevance of this metabolic route for ciclotropium bromide (HIT-PCE, CAS 85166-20-7) including its stereochemical

TTK kinase was identified by in-house siRNA screen and pursued as a tractable, novel target for cancer treatment. A screening campaign and systematic optimization, supported by computer modeling led to an indazole core with key sulfamoylphenyl and acetamido moieties at
