Current antimicrobial drug discovery and advancement attempts are aimed to identify new complexes that can work effectively against the infections caused by microbes. The aim of present study was synthesize diorganotin(IV) N'-((8-hydroxy-1,2,3,5,6,7-hexahydropyrido[3,2,1-ij]quinolin-9-yl)methylene)-2-nitrobenzohydrazide (H2L1), N'-((8-hydroxy-1,2,3,5,6,7-hexahydropyrido[3,2,1-ij]quinolin-9-yl)m...
Baicalein (1), 6-hydroxyapigenin (6), 6-hydroxygalangin (13) and 6-hydroxy-kaempferol (14), which are naturally occurring flavonoids from a set of 14 hydroxy-flavones tested, exhibited high inhibitory effects on tyrosinase with respect to L-DOPA, while each of the 5,6,7-trihydroxyflavones 1, 6, 13 or 14 acted as a cofactor to monophenolase. Moreover, 6-hydroxykaempferol (14) showed the highest ...
Four new secondary metabolites, 3α-((E)-Dodec-1-enyl)-4β-hydroxy-5β-methyldihydrofuran-2-one (1), linderinol (6), 4'-O-methylkaempferol 3-O-α-L-(4''-E-p-coumaroyl)rhamnoside (11) and kaempferol 3-O-α-L-(4''-Z-p-coumaroyl)rhamnoside (12) with eleven known compounds-3-epilistenolide D1 (2), 3-epilistenolide D2 (3), (3Z,4α,5β)-3-(dodec-11-ynylidene)-4-hydroxy-5-methylbutanolide (4), (3E,4β,5β)-3-(...
SBA-15 was prepared and then functionalized with N-methyl-N’-propyltrimethoxysilyl imidazolium chloride as ionic liquid moiety. The ionic liquid functionalized SBA-15 (SBA-IL) was characterized by different analytical techniques including FT-IR, N2 adsorption-desorption, TGA and SEM image. According to the obtained results it was found that the organic groups were g...
Abstract There is zero tolerance for dicamba and metabolite residue in tomato ( Solanum lycopersicum L.) fruit following exposure to dicamba. Field trials were conducted 2020 2021 determine the persistence of (5-hydroxy 3,6-dichlorosalicylic acid [DCSA]) processing shoots fruits. Dicamba was applied 49 d after transplanting at 0, 0.53, 5.3, 53 g ae ha −1 . Tomato plants harvested 5, 10, 20, 40,...
