In this research, the effect of synthesized polyphenoliccompounds 4 and 5 at the cellular and molecular levels was examined. Within this framework, related substances effects on prostate cell (PC3) viability were evaluated by MTT analysis, and their effects on migration were examined by in vitro scratch analysis. Additionally, mRNA expression levels of gene regions known to be associated with metastasis

We are attempting to develop the novel phenolic synthetic antioxidants aimed at retarding the effects of free radicals and oxidants. The phenolic compounds (7-12) were synthesized by Friedel-Crafts alkylation of isoeugenol (1) and phenol derivatives (2-6) and their structures were determined by spectroscopic methods. All the synthesized phenolic compounds (7-12) except 12 are new. Antioxidant and radical scavenging activities of synthesized compounds (7-12) were determined by using various in vitro assays such as 1,1-diphenyl-2-picrylhydrazyl free radicals (DPPH), 2,2-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) radicals (ABTS(+)), and superoxide anion radicals (O-2(-)) scavenging, ferric reducing antioxidant power (FRAP) and total antioxidant activity by ferric thiocyanate. The antioxidant activities of compounds were compared with standard antioxidants such as butylated hydroxyanisole (BHA), butylated hydroxytoluene (BHT) and trolox as positive controls. The results showed that the synthesized compounds, especially 10 and 11, had better properties than standard antioxidants (BHT. BHA and trolox). (C) 2011 Elsevier Masson SAS. All rights reserved.

Phenolic compounds mainly benefit human health and have many biological activities. Their activities are related to their structure, which allows them to interact with enzymes. The inhibition potencies of synthesized polyphenolic compounds (3a and 3b) were investigated on cholinesterases, α‑Gly, and tyrosinase activities. The structures of 3a and 3b were determined based on spectral data (NMR, UV–vis
