“…Heterocycles display an impressively high biological potential and were also used as important intermediates in the area of organic synthesis. Derivatives containing the 2-thioxothiazolidin-4-one (rhodanine) substructure are an interesting and important part of this wide library of bioactive compounds and exhibit a wide variety of biological activities, 1,2 as anti-fungal, 3 antibacterial, [4][5][6][7] anti-inflammatory, [8][9][10] anti-cancer, [11][12][13] anti-Alzheimer, 14,15 anti-viral [16][17][18] and anti-diabetic (Figure 1). [19][20][21][22] More precisely, they act, for example, as inhibitors of aldose reductase, protein tyrosine phosphatase PTP, aggregation of Tau proteins, HIV-1 integrase, hepatitis C virus, protease and - In addition, they are versatile synthetic intermediates since they can undergo many chemical transformations, such as hydrolysis in basic medium to lead to mercaptoacrylic acids, 23 Michael-type addition, 24 Diels Alder reactions to access dihydropyrans 25 and 2-thioxopyrano [2,3-d] [1,3]thiazoles.…”
