7-Arylsulfonyl substituted benzofuropiperidine was discovered as a novel scaffold for 5HT(6) receptor antagonists. Optimization by substitution at C-1 position led to identification of selective, orally bioavailable, brain penetrant antagonists with reduced hERG liability. An advanced analog tested in rat social recognition model showed significant activity suggesting potential utility in the enhancement of short-term memory. (C) 2011 Elsevier Ltd. All rights reserved.

Compounds in a structurally novel series of substituted 10H-benzo[4,5]furo[3,2-b]indole-1-carboxylic acids and related 5,10-dihydro-indeno[1,2-b]indole-1-carboxylic acids were prepared and shown to possess potent, bladder-selective smooth muscle relaxant properties and thus are potentially useful for the treatment of urge urinary incontinence.

kinase-related apoptosis-inducing kinase-2 (DRAK2) is a serine/threonine kinase that plays a key role in a wide variety of cell death signaling pathways. Inhibition of DRAK2 was found to efficiently protect islet β-cells from apoptosis and hence DRAK2inhibitors represent a promising therapeutic strategy for the treatment of diabetes. Only very few chemical entities targeting DRAK2 are currently known. We carried
fluorinated and iodinatedradiotracer as a probe for PET/SPECT to detect of β-amyloid (Aβ) plaques in the brain of patients with Alzheimer’s disease (AD). We successfully designed and synthesized the fluorinated and iodinated aurone derivative (3) and its radiolabels ([125I]3 and [18F]3). In binding experiments in vitro, 3 showed high affinity for Aβ aggregates (Ki = 6.81 nM). In brain sections of AD

aggregates. In the present study, we designed and synthesized four radioiodinated phenylbenzofuranone (PBF) derivatives: [123/125I]IDPBF-2, [123/125I]INPBF-2, [123/125I]IDPBF-3, and [123/125I]INPBF-3, as candidates for α-syn imaging probes. All fourcompounds exhibited high binding affinity for recombinant α-syn aggregates in an inhibition assay. However, brainuptake of all fourcompounds was insufficient
