Small Molecule Inhibitors of Regulators of G Protein Signaling (RGS) Proteins
摘要:
Recently, regulators of G protein signaling (RGS) proteins have emerged as potential therapeutic targets since they provide an alternative method of modulating the activity of G protein-coupled receptors, the target of so many drugs. Inhibitors of RGS proteins must block a protein protein interaction (RGS-G alpha) but also be cell and, depending on the therapeutic target, blood brain barrier permeable. A lead compound (la) was identified as an inhibitor of RGS4 in a screening assay, and this has now been optimized for activity, selectivity, and solubility. The newly developed ligands (11b and 13) display substantial selectivity over the closely related RGS8 protein, lack the off-target calcium mobilization activity of the lead la, and have excellent aqueous solubility. They are currently being evaluated in vivo in rodent models of depression.
The invention relates to compositions having RGS (regulator of G-protein Signaling) inhibiting activity, and methods of use thereof. In some embodiments, RGS-inhibiting compositions find use in research on or treatment of disease states (e.g., diabetes, epilepsy, neuropathic pain, depression and other diseases).

A room temperature curable organopolysiloxane composition is provided. The composition contains a diorganopolysiloxane having at least two groups represented by the following formula (1):
per molecule as its main component. In the formula, X is —R′
d
—NH— or —R′
d
—S—, R is a substituted or unsubstituted C
1-12
monovalent hydrocarbon group, R′ is a C
1-8
divalent hydrocarbon group, Y is a hydrolyzable group, b is 2 or 3, and d is 0 or 1. The composition has excellent room temperature curability, and the cured product has excellent moisture resistance. The composition is useful as an adhesive or sealant used at a site where hardness, water resistance, and moisture resistance are required, and in particular, for an adhesive in construction applications and electric and electronic applications where steam resistance and water resistance are required.
