- Synthesis and Pharmacological Evaluation of Heterocyclic Carboxamides: Positive Allosteric Modulators of the M1 Muscarinic Acetylcholine Receptor with Weak Agonist Activity and Diverse Modulatory Profiles
-
Targeting allosteric sites at M1 muscarinic acetylcholine receptors is a promising strategy for the treatment of Alzheimer's disease. Positive allosteric modulators not only may potentiate binding and/or signaling of the endogenous agonist acetylcholine (ACh) but also may possess direct agonist activity (thus referred to as PAM-agonists). Recent studies suggest that PAM-agonists with robust intrinsic efficacy are more likely to produce adverse effects in vivo. Herein we present the synthesis and pharmacological evaluation of a series of pyrrole-3-carboxamides with a diverse range of allosteric profiles. We proposed structural modifications at top, core, or pendant moieties of a prototypical molecule. Although generally there was a correlation between the degree of agonist activity and the modulatory potency of the PAMs, some derivatives displayed weak intrinsic efficacy yet maintained strong allosteric modulation. We also identified molecules with the ability to potentiate mainly the affinity or both affinity and efficacy of ACh.

- Inhibitors of acyl-coA:cholesterol O-acyltransferase. 2. Identification and structure-activity relationships of a novel series of N-alkyl-N- (heteroaryl-substituted benzyl)-N'-arylureas
-
A series of N-alkyl-N-(heteroaryl-substituted benzyl)-N'-arylurea and related derivatives represented by 2 and 3 have been prepared and evaluated for their ability to inhibit acyl-CoA:cholesterol O-acyltransferase in vitro and to lower plasma cholesterol levels in cholesterol-fed rats in vivo. Among these novel compounds, the type 3 series was superior. A pyrazol-3-yl group on the N-benzyl group of this trisubstituted urea (i.e. 3, Ar1 = pyrazol-3- yl) was identified as a heteroaromatic ring providing a good profile of biological activity. As a result of optimization of the combination with the N-alkyl group (R) and N-aryl group (At3), compound 3aq (FR186054) was identified as a new, orally efficacious ACAT inhibitor, which exhibited potent in vitro ACAT inhibitory activity (rabbit intestinal microsomes IC50 = 99 nM) and excellent hypocholesterolemic effects in cholesterol-fed rats, irrespective of administration mode (ED50 = 0.046 mg/kg dosed via the diet, ED50 = 0.44 mg/kg administered by gavage in PEG400 vehicle). Moreover, a toxicological study revealed compound 3aq to be nontoxic to the adrenal glands of dogs when tested at a single dose of 10 mg/kg po.
