(66) stated that the substitution of urea/thiourea on disubstituted cinnamic-based hydroxamates (10) has a remarkable HDAC inhibitory effect and antiproliferative activity against tumor cell lines.
Also, being disubstituted affords the ability to vary functional groups, offering greater control of polymer properties, according to the company.
The main sign of polymerization of monomers is the dramatic decrease of characteristic bands around 930-940 [cm.sup.-1], attributed to the out-of-plane deformation mode of the [alpha],[beta]- disubstituted naphthalene ring, which indicates the opening of the oxazinic ring.
Hence, [WA-f.sub.50] and [WB-f.sub.75] had significantly different inhibition potency towards [alpha]-glucosidase activity despite having similar relative proportions unsubstituted (un-Xylp), monosubstituted, (2-Xylp or 3-Xylp), and disubstituted xylose residues (2,3-Xylp) and degree of substitution but different ferulic acid content.

A recent comparative study of the antioxidant activity of several coumarins showed that 4-methylumbelliferone was completely inactive against liver toxicity induced by carbontetrachloride, whereas other C-6 and C-7 disubstituted coumarins (esculetin and scoparone) significantly prevented oxidative stress induced by carbon-tetrachloride (Bilgin et al., 2011).
