2-Mercaptoimidazoles, a new class of potent CCR2 antagonists
摘要:
We describe the synthesis and SAR of a new class of CCR2 antagonists based on a 2-mercaptoimidazole scaffold. The initial lead 1a was optimized to the 3,4-disubstituted analogues 1p-(S) and 1q-(S), which have IC50 values in the MCP-1 induced Ca-flux below 0.01 muM. (C) 2004 Elsevier Ltd. All rights reserved.

a search for medications for cocaine abuse. Herein we describe the synthesis and biologicalevaluation of an array of 2-aminopentanophenones. This array has yielded selective inhibitors of the dopamine and norepinephrinetransporters with little effect upon serotonin trafficking. A subset of compounds had no significant affinity at 5HT1A, 5HT1B, 5HT1C, D1, D2, or D3 receptors. The lead compound, racemic

coupling-redox isomerization to form branched ketones. Use of the less strongly coordinating ligand, PPh3, promotes vinyl- to allylrhodium isomerization en route to linear ketones. This method bypasses the 3-step sequence often used to convert aldehydes to ketones involving the addition of pre-metalated reagents to Weinreb or morpholine amides.
The reactions of p-toluenesulfonylmethyl isocyanide (TosMIC) with α-bromocarbonyl compounds leading efficiently to α-sulfonated ketones, esters, and amides were reported, in which an explicit new role of TosMIC as the sulfonylating agent was uncovered for the first time. Mechanistic study by control experiments and DFT calculations suggested that the reaction is initiated by Cu(OTf)2-catalyzed hydration

The invention provides bupropion analogue compounds capable of inhibiting the reuptake of one or more monoamines. The compounds may selectively bind to one or more monoamine transporters, including those for dopamine, norepinephrine, and serotonin. Such compounds may be used to treat conditions that are responsive to inhibition of the reuptake of monoamines, including addiction, depression, and obesity.

New compounds that bind to monoamine transporters are described. The compounds of the present invention can be racemic or pure R— or S-enantiomers. Certain preferred compounds of the present invention have a high selectively dopamine transporter versus the serotonin transporter. Preferred monoamine transporters for the practice of the present invention include the dopamine transporter, the serotonin transporter and the norepinephrine transporter.
