Last decade had witnessed enormous efforts to develop therapies to treat one or more components of metabolic syndrome, a cluster of diseases including diabetes, obesity and dyslipidemia. Several newer targets are identified and evaluated to treat these metabolic disorders. Microsomal triglyceride transfer protein (MTP) has been identified as one of the promising target for the treatment of dyslipidemia.

In an effort to develop safe and efficacious compounds for the treatment of metabolic disorders, novel thiophene substituted oxazole containing α-alkoxy-phenylpropanoic acid derivatives are designed as highly potent PPARα/γ dual agonists. These compounds were found to be efficacious at picomolar concentrations. Lead compound 18d has emerged as very potent PPARα/γ dual agonist demonstrating potent antidiabetic and lipid lowering activity at a very low dose and did not exhibit any significant signs of toxicity in rodents.

Design and synthesis of a novel 3-hydroxy-cyclobut-3-ene-1,2-dione derivatives are reported and their in vitro thyroid hormone receptor selectivity has been evaluated in the thyroid luciferase receptor assay. The 3-[3,5-dichloro-4-(4-hydroxy-3-isopropylphenoxy)-phenylamino]-4-hydroxy-cyclobut-3-ene-1,2-dione 21 has shown selectivity towards thyroid hormone receptor beta.

A number of analogues of diaryl dihydropyrazole-3-carboxamides have been synthesized. Their activities were evaluated for appetite suppression and body weight reduction in animal models. Depending on the chemical modification of the selected dihydropyrazole scaffold, the lead compounds--the bisulfate salt of (+/-)-5-(4-chlorophenyl)-1-(2,4-dichlorophenyl)-4,5-dihydro-1H-pyrazole-3-carboxylic acid morpholin-4-ylamide 26 and the bisulfate salt of (-)-5-(4-chlorophenyl)-1-(2,4-dichlorophenyl)-4,5-dihydro-1H-pyrazole-3-carboxylic acid morpholin-4-ylamide 30--showed significant body weight reduction in vivo, which is attributed to their CB1 antagonistic activity and exhibited a favorable pharmacokinetic profile.
