© 2017 Peroxisome proliferator-activated receptors (PPARs) are nuclear receptors involved in the metabolism of lipids and carbohydrates. The exogenous ligands of these receptors are thiazolidinediones (TZDs), which are used to treat type 2 diabetes mellitus (DM2). However, drugs from this group produce adverse effects such as hepatic steatosis. Hence, the aim of this work was to design a set of small molecules that can activate the γ isoform of PPARs while minimizing the adverse effects. The derivatives were designed containing the polar head of TZD and an aromatic body, serving simultaneously as the body and tail. Two ligands were selected out of 130 tested. These compounds were synthesized in a solvent-free reaction and their physicochemical properties and toxicity were examined. Acute oral toxicity was determined by administering these compounds to female Wistar rats in increasing doses (as per the OECD protocol 425). The median lethal dose (LD50) of the compound substituted with a hydroxyl heteroatom was above 2000 mg/kg, and that of the compound substituted with halogens was 700–1400 mg/kg. The results suggest that the compounds can interact with PPARγ and elicit biological responses similar to other TZDs, but without showing adverse effects. The compounds will be subsequently evaluated in a DM2 animal model.
