Tert-butyl esters 3 and 3-cyanopyrrolidines 6 are prepared by phase-transfer-catalysed reactions of symmetrical 4,4′-disubstituted N-(benzylidene)benzylamines with tert-butyl cinnamate and α-phenylcinnamonitrile, respectively; similar reactions of mono-substitited N-(benzylidene)benzylamines afforded mixtures of compounds 3, respectively 6, and their regioisomers 3(A) and 6(A).

Further Development

Background: A series of novel cinnamic acid piperazine amide derivatives has been designed and synthesized, and their biological activities were also evaluated as potential tyrosinase inhibitors. Methods: Compounds 9, 11 and 17 showed the most potent biological activity (IC50 = 66.5, 61.1 and 66 µM, respectively). In silico docking simulation was performed to position compound 11 into the Agaricus bisporus mushroom tyrosinase’s active site to determine the putative binding interactions. Results and Conclusion: The results indicated that compound 11 could serve as a promising lead compound for further development of potent tyrosinase inhibitors.

A new triterpene saponin, named as 23-hydroxy-3α-[O-α-L-1C4-rhamnopyranosyl-(1´´4´)- O-α-L-4C1-arabinopyranosyl-oxy]olean-12-en-28-oic acid O-α-L-1C4-rhamnopyranosyl- (1´´´´´→4´´´´)-O-β-D-4C1-glucopyranosyl-(1´´´´→6´´´)-O-β-D-4C1-glucopyranosyl ester (9), was isolated from the leaves of Bauhinia variegata Linn. In addition, six flavonoid compounds along with two cinnamic acid derivatives were isolated and identified based on their chromatographic properties, and chemical and spectral data (ESI-high resolution-MSn, 1H NMR, 13C NMR, 1H-1H COSY, HSQC, and HMBC). Compound 9 was found to be nontoxic (LD50) and to have significant anti-inflammatory and antinociceptive activities. It also showed a slight antischistosomal activity.
