“…Production of excessive NO has been associated with a range of inflammatory diseases including arteriosclerosis, ischemic reperfusion, hypertension and septic shock (25,26). Recent studies have demonstrated that the plant foods including fruits, vegetables and medicinal herbs are an excellent source of antioxidant molecules that effectively inhibit the inflammatory process by affecting different molecular targets (27,28). In this study, methanol extract of D. atrovirens bark exhibited a higher level of total phenolics when compared with other extracts.…”

In traditional systems of medicine, the bark of Dolichandroneatrovirens has been used to treat various disorders. The main aim of this study was to determine the anti-inflammatory effect of D. atrovirens bark through the inhibition of nitric oxide (NO) production in lipopolysaccharide-stimulated RAW 264.7 cells.For this purpose, preliminary phytochemical composition and in vitro antioxidant activities of various solvent extracts of D. atrovirens bark were evaluated to select the most effective extract.The methanol extract of D.atrovirens registered the highest amount of total phenolics (476.2 mg GAE/g) and flavonoid (129.0 mg RE/g)contents witha strong antioxidant activity as measured in DPPH (IC50 of 19.52 μg/mL) and ABTS (IC50of 10.82 μg/mL) scavenging activities.Hence, the methanol extract was selected for cell line study. Further, the methanol extract of D. atrovirens effectively inhibited the production of NO in RAW 264.7 cells induced by LPS (13.1 μM at the concentration of 80 μg/mL). It could be concluded that the presence of higher level of total phenolic components in the methanol extract of D. atrovirens bark might be responsible for reducing the NO level in cells.

Chlorogenic acid (CGA) has been considered as one of important active components in a number of medicinal herbs. Recently our group demonstrated that caffeoyl salicylate scaffold derived from CGA can be employed for the development of novel anti-inflammatory agents. The most active compound D104 can be a very promising starting point for the further structural optimization. A series of novel caffeoyl salicylate analogs were designed, synthesized, and evaluated by preliminary biological evaluation. The obtained results showed that the two compounds B12 and B13 can not only inhibit production of nitric oxide (NO) in RAW264.7 cells induced by lipopolysaccharides (LPS) effectively, but also have high safety in in vitro cytotoxic test, which could be comparable with D104. Molecular docking study on the peroxisome proliferatoractivated receptor γ (PPARγ) protein revealed that compounds B12 and B13 can follow the same binding mode with D104, and the carboxyl group of caffeoyl salicylate scaffold might play a key role in the interaction with protein target, which implied the carboxyl group should be retained in the further optimization.

Retinoid N-(1H-benzo[d]imidazol-2-yl)-5,5,8,8-tetramethyl-5,6,7,8-tetrahydronaphthalene-2-carboxamide induces p21-dependent senescence in breast cancer cells

Retinoids have been implicated as pharmacological agents for the prevention and treatment of various types of cancers, including breast cancers. We analyzed 27 newly synthesized retinoids for their bioactivity on breast, liver, and colon cancer cells. Majority of the retinoids demonstrated selective bioactivity on breast cancer cells. Retinoid 17 had a significant inhibitory activity (IC50 3.5 μM) only on breast cancer cells while no growth inhibition observed with liver and colon cancer cells. The breast cancer selective growth inhibitory action by retinoid 17 was defined as p21-dependent cell death, reminiscent of senescence, which is an indicator of targeted receptor mediated bioactivity. A comparative analysis of retinoid receptor gene expression levels in different breast cancer cells and IC50 values of 17 indicated the involvement of Retinoid X receptors in the cytotoxic bioactivity of retinoid 17 in the senescence associated cell death. Furthermore, siRNA knockdown studies with RXRγ induced decrease in cell proliferation. Therefore, we suggest that retinoid derivatives that target RXRγ, can be considered for breast cancer therapies.
