A series of nine novel thiazole linked chalcones, (E)-3-(4-methyl-2-(4(trifluoromethyl)phenyl)thiazol-5-yl)-1-phenylprop-2-en-1-one derivatives 7–15 were synthesized. To establish the structure–activity relationship (SAR), furthermore, the corresponding, ring-closed pyrimidine analogs 17–23 were synthesized. The derivatives thus obtained were evaluated for their anti-cancer activity against three genetically different colorectal cancer (CRC) cell lines. Thiazole derivatives 7, 9, and10 showed anti-cancer activity with GI50 values ranging from 0.19 to 100 μM. Importantly, compounds 7 and 10 outperformed the standard drug cisplatin in the tested cell lines and thus show promise for further optimization. Some of pyrimidine derivatives retain activity comparable to cisplatin in the HT-29 cell line, e.g. compounds 17 and 18 with IC50 of 25?μM, however, none of these compounds demonstrated improved antiproliferative activity as compared with the starting thiazole, thus the enone linker was critical for obtaining more active compounds in this series.

The peroxisome proliferator activated receptors PPARα, PPARγ, and PPARδ are ligand-activated transcription factors that play a key role in lipid homeostasis. The fibrates raise circulating levels of high-density lipoprotein cholesterol and lower levels of triglycerides in part through their activity as PPARα agonists; however, the low potency and restricted selectivity of the fibrates may limit their efficacy, and it would be desirable to develop more potent and selective PPARα agonists. Modification of the selective PPARδ agonist 1 (GW501516) so as to incorporate the 2-aryl-2-methylpropionic acid group of the fibrates led to a marked shift in potency and selectivity toward PPARα agonism. Optimization of the series gave 25a, which shows EC50 = 4 nM on PPARα and at least 500-fold selectivity versus PPARγ and PPARγ. Compound 25a (GW590735) has been progressed to clinical trials for the treatment of diseases of lipid imbalance.
