One flavone ZN-006 [2-((5-hydroxy-4-oxo-2-phenyl-4H-chromen-7-yl)oxy)acetic acid], one benzofuran ZN-013 [(4-methoxybenzofuran-2-yl)(phenyl)methanone], and four quinolines VB-030 [2-(pyridin-4-yl)-4-(p-tolyl)quinoline], VB-031 [(E)-3-(3-(1H-benzo[d]imidazol-2-yl)acryloyl)-6-methyl-4-phenylquinolin-2(1H)-one], VB-037 [(E)-4-(3-(2-(5-nitroquinolin-2-yl)vinyl)quinolin-2-yl)morpholine] and VB-041 [2-(pyridin-4-yl)-N-(3-(N-(3,4,5,6-tetrahydro-2H-azepin-7-yl)sulfamoyl)phenyl)quinoline-4-carboxamide] were purchased from Enamine (Kyiv, Ukraine). Procedures for producing coumarins ZN-014 (ethyl 5-hydroxy-2-oxo- 2H-chromene-3-carboxylate) and ZN-015 [(E)-4-hydroxy-3-(3-(2-hydroxyphenyl)acryloyl)-2H-chromen-2-one] were as stated [28 (link)]. Congo red, kaempferol and 7,8-DHF, controls for cellular and/or biochemical assays were obtained from Sigma-Aldrich (St. Louis, MO, USA). In addition, LM-031 (3-benzoyl-5-hydroxychromen-2-one), a control for evaluating TRKB signaling, was synthesized as stated [30 (link)].
