Synthesis and biological evaluation of some stilbene derivatives
摘要:
Several trans and cis stilbenes with substitution on the olefinic bridge were synthesized and characterized by IR, NMR and mass spectroscopy in an effort to obtain substances that could be more readily formulated. All the synthesized compounds were screened against Molt4/C8, CEM and L1210 cell lines. None of these compounds were endowed with pronounced cytostatic activity. However, Schiff derivatives emerged as cytostatic agents (IC(50): 0.77-10 mu g/ml) that deserve further investigation.

deals with the preparation of stilbene-based resveratrol analogs by employing the Perkin reaction, aiming at synthesizing potential antitumor lead compounds and evaluating their pharmacological activities. The proliferation inhibitor test against tumor cell lines identified analogs 9 and 11 as the most active among all synthesized derivatives, presenting IC50 in micromolar range for certain cell lines

Antioxidant, anti-tyrosinase and anti-melanogenic effects of (E)-2,3-diphenylacrylic acid derivatives
(E)-2,3-DPA derivatives 1a-1n and one (Z)-2,3-DPA-derivative 1l' using a Perkin reaction with phenylacetic acid and appropriate substituted benzaldehydes. In our mushroomtyrosinase assay, 1c showed higher tyrosinase inhibitory activity (76.43 ± 3.53%, IC50 = 20.04 ± 1.91 µM) with than the other 2,3-DPA derivatives or kojic acid (21.56 ± 2.93%, IC50 = 30.64 ± 1.27 μM). Our mushroomtyrosinase inhibitory
