The discovery of a second estrogen receptor (ER), called ERbeta, in 1996 sparked intense interest within the scientific community to discover its role in mediating estrogen action. However, despite more than 6 yr of research into the function of this receptor, its physiological role in mediating estrogen action remains unclear and controversial. We have(More)
A series of 2-(aminomethyl)chromans (2-AMCs) was synthesized and evaluated for their affinity and selectivity for both the high- and low-affinity agonist states (D2High and D2Low, respectively) of the dopamine (DA) D2 receptor. The 7-hydroxy-2-(aminomethyl)chroman moiety was observed to be the primary D2 agonist pharmacophore. The 2-methylchroman moiety was(More)
The 2-phenylnaphthalene scaffold was explored as a simplified version of genistein in order to identify ER selective ligands. With the aid of docking studies, positions 1, 4, and 8 of the 2-phenylnaphthalene template were predicted to be the most potentially influential positions to enhance ER selectivity using two different binding orientations. Both(More)
BACKGROUND Nonsteroidal agonists have been developed that selectively bind to and activate estrogen receptor beta (ERbeta) rather than estrogen receptor alpha (ERalpha). ERbeta is expressed equally in both male and female mammals in multiple extragonadal tissues. Work reported elsewhere has demonstrated that ERbeta agonists have beneficial effects in(More)
The synthesis of several bioisosteric analogs based on the 3-OH-N1-phenylpiperazine dopamine D2 agonist template (i.e., 4) is described. The indolone (5) and 2-CF3-benzimidazole (13) were observed to have excellent affinity for the D2 receptor. Several D4 selective compounds were also identified. Molecular modeling studies and a putative bioactive(More)
A new class of estrogen receptor beta (ERbeta) ligands based on the 6H-chromeno[4,3-b]quinoline scaffold has been prepared. Several C7-substituted analogues displayed high affinity and modest selectivity for ERbeta.
Leumedins are small organic molecules with anti-inflammatory properties in vivo. We report here that leumedins inhibit the CD11b/CD18 alpha M beta 2 (Mac-1)-dependent adherence of neutrophils to serum proteins. The activation of neutrophils leading to adherence via Mac-1 is associated with an increase in cell surface Mac-1 level, and with an increased(More)
Compounds containing a 5-carbamoyl-8-fluoro-3-amino-3,4-dihydro-2H-1-benzopyran and a 3-alkylindole moiety linked through a common basic nitrogen were prepared and evaluated for 5-HT1A affinity, serotonin rat transporter affinity, and functional antagonist activity in vitro. 26a was found to be the most potent and selective compound in this series and was(More)
A new class of estrogen receptor beta (ERbeta) ligands based on the 2-phenylquinoline scaffold was prepared. Several analogues with C4 substitution displayed high affinity (3-5 nM) and significant selectivity (up to 83-fold) for ERbeta. The best compound, 13b, was profiled as a selective partial agonist for ERbeta at 1 muM in a cell-based transcriptional(More)
