Mitochondria are pivotal energy production sources for cells to maintain necessary metabolism activities. Targeting dysfunctional mitochondrial features has been a hotspot for mitochondrial-related disease researches. Investigation with cancerous mitochondrial metabolism is a continuing concern within tumor therapy. Herein, we set out to assess the anti-cancer activities of a novel family of TPP-thiazole derivatives based on our earlier research on mitochondrial targeting agents. Specifically, we designed and synthesized a series of TPP-thiazole derivatives and revealed by the MTT assay that most synthesized compounds effectively inhibited three cancer cell lines (HeLa, PC3 and MCF-7). After structure modifications, we explored the SAR relationships and identified the most promising compound R13 (IC50 of 5.52 μM) for further investigation. In the meantime, we performed ATP production assay to assess the selected compounds inhibitory effect on HeLa cells energy production. The results displayed the test compounds significantly restrained ATP production of cancer cells. Overall, we have designed and synthesized a series of compounds which exhibited significant cytotoxicity against cancer cells and effectively inhibited mitochondrial energy production.

We synthesized a directed library of compounds to explore the structure-activity relationships of peroxisome proliferator-activated receptor δ(PPARδ) activation relative to mesenchymal stem cell (MSC) osteogenesis. Our scaffold used para-substituted cinnamic acids as a polar headgroup, a heteroatom and heterocycle core connecting units, and substituted phenyl groups for the lipophilic tail. Compounds were screened for their ability to increase osteogenesis in MSCs, and the most promising were examined for subunit specificity using a quantitative PPAR transactivation assay. Six compounds were selected for in vivo studies in an ovariectomized mouse model of human postmenopausal osteoporosis. Four compounds improved bone density in vivo, with two (12d and 31a) having activity comparable to that of GW0742, a well-studied PPARδ-selective agonist. 31a (2-methyl-4-[N-methyl-N-[5-methylene-4-methyl-2-[4-(trifluoromethyl)phenyl]thiazole]]aminocinnamic acid) had the highest selectivity for PPARδcompared to other subtypes, its selectivity far exceeding that of GW0742. Our results confirm that PPARδis a new drug target for possible treatment of osteoporosis via in situ manipulation of MSCs.

The increase in antibiotic resistance due to multiple factors has warranted the need for search of new compounds which are active against multidrug resistant pathogens. In this context a small focused library of thiosemicarbazide derivatives of 2-arylthiazole-4-carbaldehyde, 4-methyl-2-arylthiazole-5-carbaldehyde and 1-(4-methyl-2-arylthiazol-5-yl) ethanone, (5a–l) has been synthesized. The title compounds were screened for inhibitory activity against Mycobacterium tuberculosis H37Ra (ATCC 25177) and Mycobacterium bovis Bacille Calmette Guerin (ATCC 35743) strains. The synthesized compounds, 5a–l were further assayed for their cytotoxic activity against the two human cancer cell lines, HeLa and human colon carcinoma 116 cell lines and showed no significant cytotoxic activity against these two cell lines at the maximum concentration evaluated. Further, the synthesized compounds were found to have potential antibacterial activity against Gram-negative bacteria, Escherichia coli, Pseudomonas flurescence and Gram-positive bacteria, Staphylococcus aureus, Bacillus subtilis. Most of the synthesized compounds showed moderate activity against fungal strain Candida albicans. This study provides valuable directions to our ongoing endeavor of rationally designing more potent antimycobacterial agent.

The free fatty acid receptor 1 (FFA1/GPR40) has attracted interest as a novel target for the treatment of type 2 diabetes. Several series of FFA1 agonists including TAK-875, the most advanced compound terminated in phase III studies due to concerns about liver toxicity, have been hampered by relatively high molecular weight and lipophilicity. Aiming to develop potent FFA1 agonists with low risk of liver toxicity by decreasing the lipophilicity, the middle phenyl of TAK-875 was replaced by 11 polar five-membered heteroaromatics. Subsequently, systematic exploration of SAR and application of molecular modeling, leads to the identification of compound 44, which was an excellent FFA1 agonist with robustly hypoglycemic effect both in normal and type 2 diabetic mice, low risks of hypoglycemia and liver toxicity even at the twice molar dose of TAK-875. Meanwhile, two important findings were noted. First, the methyl group in our thiazole series occupied a small hydrophobic subpocket which had no interactions with TAK-875. Furthermore, the agonistic activity revealed a good correlation with the dihedral angle between thiazole core and the terminal benzene ring. These results promote the understanding of ligand-binding pocket and might help to design more promising FFA1 agonists.

Therapeutics of metastatic or triple-negative breast cancer are still challenging in clinical. Herein we demonstrated the design and optimization of a series of hybrid of 2,4-diaminopyrimidine and arylthiazole derivatives for their anti-proliferative properties against two breast cancer cell lines (MCF-7 as human breast cancer and MDA-MB-231 as triple-negative breast cancer). More importantly, some of those compounds with potent antiproliferative activities also indicated excellent inhibitory activities against MDA-MB-231 cell migration. These results suggested that the new series of hybridation of aryl-thiazoles and aminopyrimidines could be identified and developed as novel highly potential anticancer agents against the triple-negative breast cancer as well as metastatic one in the future.
