Novel sulfonylurea derivatives as H3 receptor antagonists. Preliminary SAR studies
摘要:
The combination of antagonism at histamine H-3 receptor and the stimulation of insulin secretion have been proposed as an approach to new dual therapeutic agents for the treatment of type 2 diabetes mellitus associated with obesity. We have designed and synthesized a new series of non-imidazole derivatives, based on a basic amine ring connected through an alkyl spacer of variable length to a phenoxysulfonylurea moiety. These compounds were initially evaluated for histamine H-3 receptor binding affinities, suggesting that a propoxy chain linker between the amine and the core ring could be essential for optimal binding affinity. Compound 56, 1-(naphthalen-1-yl)-3-[(p-(3-pyrrolidin-1-ylpropoxy) benzene)]sulfonylurea exhibited the best H-3 antagonism affinity. However, since all these derivatives failed to block K-ATP channels, the link of these two related moieties should not be considered a good pharmacophore for obtaining new dual H-3 antagonists with insulinotropic activity, suggesting the necessity to propose a new chemical hybrid prototype.

Novel Fluorinated Derivatives of the Broad-Spectrum MMP Inhibitors <i>N</i>-Hydroxy-2(<i>R</i>)-[[(4-methoxyphenyl)sulfonyl](benzyl)- and (3-picolyl)-amino]-3-methyl-butanamide as Potential Tools for the Molecular Imaging of Activated MMPs with PET
An approach to the in vivo imaging of locally upregulated and activated matrix metalloproteinases (MMPs) found in many pathological processes is offered by positron emission tomography (PET). Hence, appropriate PET radioligands for MMP imaging are required. Here, we describe the syntheses of novel fluorinated MMP inhibitors (MMPIs) based on lead structures of the broad-spectrum inhibitors N-hydrox
