Compounds, pharmaceutical compositions and methods are provided that are useful in the treatment or prevention of lipid disorders, metabolic disorders and cell-proliferative diseases. In particular, the invention provides compounds which modulate the expression and/or function of proteins involved in cholesterol metabolism. The subject compounds are particularly useful in the treatment of obesity, diabetes, hypercholesterolemia, atherosclerosis and hypolipoproteinemia.
A compound represented by general formula (I) (in the formula, all symbols are as described in the description) or a salt thereof has a potent nerve-protecting and/or -repairing activity, and therefore can be used as a therapeutic agent for neuropathy (e.g., chronic inflammatory demyelinating polyneuropathy, Guillain-Barre syndrome, periarteritis nodosa, allergic vasculitis, diabetic peripheral neuropathy, entrapment neuropathy, peripheral neuropathy associated with the administration of a chemotherapeutic drug, or peripheral neuropathy associated with Charcot-Marie-Tooth disease).

Microwave-induced syntheses of sulfonamides, without using base under solvent-free conditions, have been developed. The process finds its utility because of its simple operational procedure and high yields. Moreover, the process is fast and accommodative to different substituents on aromatic as well as heteroaromatic rings rendering sulfonamides (28 examples).

The phosphoinositide 3-kinases (PI3Ks) have been linked to an extraordinarily diversified group of cellular functions making these enzymes compelling targets for the treatment of disease. A large body of evidence has linked PI3K gamma to the modulation of autoimmune and inflammatory processes making it an intriguing target for drug discovery. Our high-throughput screening (HTS) campaign revealed two hits that were nominated for further optimization studies. The in vitro activity of the first HTS hit, designated as the sulfonylpiperazine scaffold, was optimized utilizing structure-based design. However, nonoptimal pharmacokinetic properties precluded this series from further studies. An overlay of the X-ray structures of the sulfonylpiperazine scaffold and the second HTS hit within their complexes with PI3K gamma revealed a high degree of overlap. This feature was utilized to design a series of hybrid analogues including advanced leads such as 31 with desirable potency, selectivity, and oral bioavailability.
