The xanthine oxidase (XO) plays an important role in producing uric acid, and therefore XO inhibitors are considered as one of the promising therapies for hyperuricemia and gout. We have previously reported a series of XO inhibitors with pyrazole scaffold to extend the chemical space of current XO inhibitors. Herein, we describe further structural optimization to explore the optimal heterocycle by replacing the thiazole ring of Febuxostat with 5 heterocycle scaffolds unexplored in this field. All of these efforts resulted in the identification of compound 8, a potent XO inhibitor (IC50 = 48.6 nM) with novel 2-phenylthiazole-4-carboxylic acid scaffold. Moreover, lead compound 8 exhibited hypouricemic effect in potassium oxonate-hypoxanthine-induced hyperuricemic mice. These results promote the understanding of ligand-receptor interaction and might help to design more promising XO inhibitors.

In this paper we report a synthesis of a series of nonlinear optical donor-acceptor chromophores, derivatives of bisphenol A. The studied compounds contain azo bonds with substituted thiazole ring as side groups. Their molecular first hyperpolarizablities were measured by solvatochromic method. The experimental values were compared with the results of semi-empirical calculations. The structures of obtained compounds were confirmed by infrared, 1H NMR and ultraviolet spectroscopy. Design of nonlinear-optical polymers with included chromophores was also performed.

Treatment of 4,5-bis(dlbromomethyl)thiazole (1a) with sodium iodide in DMF led to 4,5-bis(bromomethylene)-4,5-dihydrothiazole (2a). Trapping the latter in situ with dienophiles afforded directly the aromatized cycloadducts. Starting with 5-hydroxynaphthoquinone or its 2- and 3-bromo derivatives 6 gave a mixture of the tetracyclic quinones 10 + 11 from which the 1,6-regioisomer 10 predominates. Using acrylate dienophiles gave 6-substituted benzothiazoles 13 as the major products. The regiochemistry of the cycloadditions between 2a and naphthoquinones 6 agrees with the predictions of the frontier molecular orbital theory. In contrast, the regioselectivity observed from 2a and acrylate dienophiles 12, similar to that previously obtained with 5-bromomethylene-4-methylene-4,5-dihydrothiazole (2b), is opposite to that predicted and could be better accomodated by a competitive Michael addition followed by a cyclization-elimination step.
