Eicosanoids like leukotrienes and prostaglandins play a considerable role in inflammation. Produced within the arachidonic acid (AA) cascade, these lipid mediators are involved in the pathogenesis of pain as well as acute and chronic inflammatory diseases like rheumatoid arthritis and asthma. With regard to the lipid cross-talk within the AA pathway, a promising approach for an effective anti-inflammatory therapy is the development of inhibitors targeting more than one enzyme of this cascade. Within this study, thirty N-4-diaryl-1,3-thiazole-2- amine based compounds with different substitution patterns were synthesized and tested in various cell-based assays to investigate their activity and selectivity profile concerning five key enzymes involved in eicosanoid metabolism (5-, 12-, 15-lipoxygenase (LO), cyclooxygenase-1 and -2 (COX-1/-2)). With compound 7, 2-(4-phenyl)thiazol-2-ylamino)phenol (ST-1355), a multi-target ligand targeting all tested enzymes is presented, whereas compound 9, 2-(4-(4-chlorophenyl)thiazol-2-ylamino)phenol (ST-1705), represents a potent and selective 5-LO and COX-2 inhibitor with an IC50 value of 0.9 ± 0.2 μM (5-LO) and a residual activity of 9.1 ± 1.1% at 10 μM (COX-2 product formation). The promising characteristics and the additional non-cytotoxic profile of both compounds reveal new lead structures for the treatment of eicosanoid-mediated diseases.

Androgen receptor (AR) is ligand-inducible nuclear hormone receptor which has been focused on key molecular target in growth and progression of prostate cancer. We synthesized a series of 4-aryl 2-substituted aniline-thiazole analogs and evaluated their anti-cancer activity in AR-dependent human prostate cancer LNCap cells. Among them, the compound 6 inhibited the tumor growth in LNCap-inoculated xenograft model.

Biological evaluation of N-aryl-4-aryl-1,3-thiazole-2-amine derivatives was examined for anti-inflammatory activity in in vitro and in vivo assays. The thiazole compounds showed direct inhibition of 5-lipoxygenase (LOX) that is a key enzyme of leukotrienes synthesis and involved in the inflammation-related diseases, including asthma and rheumatoid arthritis. To optimize biological activity, we synthesized 1,3-thiazole-2-amine derivatives and investigated for structure and activity relationship. Especially, N-(3,5-dimethylphenyl)-4-(4-chlorophenyl)-1,3-thiazole-2-amine was shown to have a potent anti-inflammatory activity as a 5-LOX inhibitor.

The identification of a proper lead compound for fructose 1,6-bisphosphatase (FBPase) is a critical step in the process of developing novel therapeutics against type-2 diabetes. Herein, we have successfully generated a library of allosteric inhibitors against FBPase as potential anti-diabetic drugs, of which, the lead compound 1b was identified through utilizing a virtual high-throughput screening (vHTS) system, which we have developed. The thiazole-based core structure was synthesized via the condensation of α-bromo-ketones with thioureas and substituents on the two aryl rings were varied. 4c was found to inhibit pig kidney FBPase approximately fivefold better than 1b. In addition, we have also identified 10b, a tight binding fragment, which can be use for fragment-based drug design purposes.
