Hybrid of calix[4]resorcinarene and chitosan has been prepared via amide bond formation as the key step between ester groups attached on calix[4]resorcinarene and amine group of chitosan. The synthesis was commenced by functionalizing hydroxyl group of vanillin with methyl-2-chloroacetate via Williamson synthesis. The acid catalyzed-tandem condensation-cyclization of vanillin derivative and resorcinol gave C-4-methoxycarbonylmethoxy-3-methoxyphenylcalix[4]resorcinarene. The calix[4]resorcinarene installed with the ester group was then coupled with amine group of chitosan to form hybrid of calix[4]resorcinarene and chitosan. The IR, XRD and SEM analyses of the hybrid revealed that physical properties of the hybrid were similar to chitosan.

A series of highly potent antihyperlipidemic agents constituted by a fibrate-based structure was recently reported by our group, whose synthesis started from isovanillin derivatives. In the interest of evaluating the bioisosteric effect of the vanillin-based isomers on their antihyperlipidemic activity, the present study focuses on the synthesis of 5-acyl-1-phenoxyacetic methyl esters 5a–c and their saturated side-chain 5-alkyl-1-phenoxyacetates 6a–c. Their strong in vivo effect was associated with the inhibition of HMG-CoA reductase. Since 1,2-dihydroquinolines inhibit this enzyme, a series of such heterocycles (9a–d) was prepared by our efficient regioselective, one-step, solvent-free method. Apart from showing hypolipidemic activity in vivo, some of the compounds displayed antifungal, antioxidant and cytotoxic activity in vitro. The binding mode of four compounds at the active site of HMGRh was examined with docking simulations, observing an interaction with most of the amino acids targeted by simvastatin.
Targeting receptor tyrosine kinase VEGFR-2 in hepatocellular cancer: Rational design, synthesis and biological evaluation of 1,2-disubstituted benzimidazoles

In this study, a novel series of 1,2-disubstituted benzo[d]imidazoles was rationally designed as VEGFR-2 inhibitors targeting hepatocellular carcinoma. Our design strategy is twofold; it aimed first at studying the effect of replacing the 5-methylfuryl moiety of the well-known antiangiogenic 2-furylbenzimidazoles with an isopropyl moiety on the VEGFR-2 inhibitory activity and the cytotoxic activity. Our second objective was to further optimize the structures of the benzimidazole derivatives through elongation of the side chains at their one-position for the design of more potent type II-like VEGFR-2 inhibitors. The designed 1,2-disubstituted benzimidazoles demonstrated potent cytotoxic activity against the HepG2 cell line, reaching IC50 = 1.98 μM in comparison to sorafenib (IC50 = 10.99 μM). In addition, the synthesized compounds revealed promising VEGFR-2 inhibitory activity in the HepG2 cell line, e.g., compounds 17a and 6 showed 82% and 80% inhibition, respectively, in comparison to sorafenib (% inhibition = 92%). Studying the effect of 17a on the HepG2 cell cycle demonstrated that 17a arrested the cell cycle at the G2/M phase and induced a dose-dependent apoptotic effect. Molecular docking studies of the synthesized 1,2-disubstituted benzimidazoles in the VEGFR-2 active site displayed their ability to accomplish the essential hydrogen bonding and hydrophobic interactions for optimum inhibitory activity.

, p. 384 - 391 (2014/01/06)
A practical eight-step synthesis of lignanamide cannabisin F starting from vanillin is reported for the first time. This synthetic strategy applies the aldol reaction followed by the Wittig reaction to afford the key 8-O-4′-neolignan intermediate diacid. The diacid was condensed with N,O-protected tyramine giving, after deprotection, cannabisin F.
