Abstract: Two series of 16 novel aminoalkylated chalcone derivatives 2a–h and 3a–h were synthesized from 2′-hydroxy-3,4,4′,6′-tetramethoxychalcone (1) through extending alkoxy side chain at the 2′-position, and introducting amine hydrogen bond receptor at the end of the side chain. Their in vitro antiproliferative activities were evaluated on a panel of three human cell lines (Hela, HCC1954, and SK-OV-3) by CCK-8 assay. The results showed that all the target compounds, except compound 3e, exhibited moderate to potent antiproliferative activities against these three human cancer cells with the IC50 values of 6.78–64.45 μmol/L, in particular compounds 2g (on Hela cells), 2c (on HCC1954 cells), and 2c, 2d (on SK-OV-3 cells) possess IC50 values below 10 μmol/L. It showed the introduction of aminoalkyl moiety at 2′-O-position of chalcone 1 resulted to produce the desired effect of increasing the antiproliferative activities, and the distance between the amino groups and chalcone moiety plays an important role, the optimal number of methylene units is two-carbon spacer. Graphical abstract: A series of 16 novel aminoalkylated chalcones were synthesized and their antiproliferative acivities on three human cancer cells were evaluated.

Changes in specialized metabolites were analyzed in barley (Hordeum vulgare) leaves treated with CuCl2 solution as an elicitor. LC-MS analysis of the CuCl2-treated leaves showed the induced accumulation of three compounds. Among them

Inflammation is a complex biological response to stimuli. Activated macrophages induced excessively release of pro-inflammatory cytokines and mediators such as endogenous radical nitric oxide (NO) play a significant role in the progression of multiple inflammatory diseases. Both natural and synthetic chalcones possess a wide range of bioactivities. In this work, thirty-nine chalcones and three related compounds, including several novel ones, based on bioactive kava chalcones were designed, synthesized and their inhibitory effects on NO production in RAW 264.7 cells were evaluated. The novel compound (E)-1-(2′-hydroxy-4′,6′-dimethoxyphenyl)-3-(3-methoxy-4-(3-morpholinopropoxy)phenyl)prop-2-en-1-one (53) exhibited a better inhibitory activity (84.0%) on NO production at 10 μM (IC50 = 6.4 μM) with the lowest cytotoxicity (IC50 > 80 μM) among the tested compounds. Besides, western blot analysis indicated that compound 53 was a potent down-regulator of inducible nitric oxide synthase (iNOS) protein. Docking study revealed that compound 53 also can dock into the active site of iNOS. Furthermore, at the dose of 10 mg/kg/day, compound 53 could both significantly suppress the progression of inflammation on collagen-induced arthritis (CIA) and adjuvant-induced arthritis (AIA) models. In addition, the structure-activity relationship (SAR) of the kava chalcones based analogs was also depicted.
