Structures, antitrypanosomal activity, cytotoxicity and biological half-life t1/2 of benzoxaboroles 110 and 111 (Adapted from [98]). (Adapted from [98]).Chalcones have attracted considerable scientific attention and continue to become a versatile scaffold in anticancer and antiprotozoal research. Previously, chalcone-type compounds had been identified to inhibit the growth of T. b. brucei and Trypanosoma cruzi parasites [101]. A novel class of chalcone enzoxaborole hybrid molecules was synthesized and evaluated as an antitrypanosomal agent. The 4-NH2 derivative 112a and 3-OMe derivative 112b (Figure 12A) were discovered to have outstanding potency against T. b. brucei (112a, IC50 : 0.024 / ; 112b, IC50 : 0.022 / ) and good cytotoxicity (L929 cells, IC50 10 /mL). The synergistic 4-NH2 -3-OMe compound 112c presented a higher toxicity (L929 cells, IC50 : 1.45 /mL) [102]. The 6-pyrrolobenzoxaboroles, 113, represent a new class of potent antitrypanosomal agents. These compounds showed an antiparasitic activity ranging from 0.03 /mL to four.02 /mL [103]. Three of your leading compounds (113a ) demonstrated higher in vitro activity against T. b. brucei (IC50 : 0.09 /mL for 113a; 0.03 /mL for 113b; 0.07 /mL for 113c) and excellent cytotoxicity (L929 cells, IC50 10 /mL for 113a an.
