Based on the hybrid pharmacophore design concept, a novel series of dual diaryl urea and N-acylhydrazone derivatives were synthesized and evaluated for their in vitro cytotoxicity by the standard MTT assay. The pharmacological results indicated that most compounds exhibited moderate to excellent activity. Moreover, compound 2g showed the most potent cytotoxicity against HL-60, A549 and MDA-MB-231 cell lines, with IC50 values of 0.22, 0.34 and 0.41 μM, respectively, which was 3.8 to 22.5 times more active than the reference compounds sorafenib and PAC-1. The promising compound 2g thus emerges as a lead for further structural modifications.

A series of polyoxygenated cinnamoylcoumarins was synthesized as conformationally constrained analogs of cytotoxic diarylpentanoids. The title compounds were tested against the viability of human chronic myelogenous leukemia (K562), human acute lymphoblastic leukemia (MOLT-4) and human breast adenocarcinoma (MCF-7) cell lines by using MTT (3-(4,5-dimethylthiazol-2-yl)-2, 5-diphenyltetrazolium bromide) assay. Among them, all 6- or 7-hydroxylated compounds 6a-h exhibited remarkable cytotoxic activity. Particularly, 7-hydroxycoumarin analog 6h showed good antiproliferative activity against all tested cell lines (IC50 values ≤ 5.5 μM). The preliminary study with selected compounds 6e and 6f showed that reactivity towards mitochondrial thiol compounds cab be considered as cytotoxic mechanism of designed compounds. Furthermore, the antioxidant activity evaluation of synthesized compounds showed that hydroxylated compounds had antioxidative potential at higher concentrations.

A new series of diaryl urea derivatives bearing N-acylhydrazone moiety were designed and synthesized. All the target compounds were evaluated for their cytotoxic activities in vitro against human lung adenocarcinoma epithelial cell line (A549), human breast cancer cell line (MDA-MB-231) and human leukemia cell line (HL-60) by standard 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay. Several compounds (1a, 1f and 1h) were further evaluated against human embryonic fibroblast, lung-derived cell line (WI38). The pharmacological results indicated that some compounds exhibited promising anticancer activities. In particular, compound 1f showed the most potent cytotoxicity against the tested three cell lines with IC50 values of 0.41 μM, 0.24 μM and 0.23 μM, respectively.
Characterization of scavengers of γ-ketoaldehydes that do not inhibit prostaglandin biosynthesis

Expression of cyclooxygenase-2 (COX-2) is associated with the development of many pathologic conditions. The product of COX-2, prostaglandin H2 (PGH2), can spontaneously rearrange to form reactive γ-ketoaldehydes called levuglandins (LGs). This γ-ketoaldehyde structure confers a high degree of reactivity on the LGs, which rapidly form covalent adducts with primary amines of protein residues. Formation of LG adducts of proteins has been demonstrated in pathologic conditions (e.g., increased levels in the hippocampus in Alzheimer's disease) and during physiologic function (platelet activation). On the basis of knowledge that lipid modification of proteins is known to cause their translocation and to alter their function, we hypothesize that modification of proteins by LG could have functional consequences. Testing this hypothesis requires an experimental approach that discriminates between the effects of protein modification by LG and the effects of cyclooxygenase-derived prostanoids acting through their G-protein coupled receptors. To achieve this goal, we have synthesized and evaluated a series of scavengers that react with LG with a potency more than 2 orders of magnitude greater than that with the ε-amine of lysine. A subset of these scavengers are shown to block the formation of LG adducts of proteins in cells without inhibiting the catalytic activity of the cyclooxygenases. Ten of these selective scavengers did not produce cytotoxicity. These results demonstrate that small molecules can scavenge LGs in cells without interfering with the formation of prostaglandins. They also provide a working hypothesis for the development of pharmacologic agents that could be used in experimental animals in vivo to assess the pathophysiological contribution of levuglandins in diseases associated with cyclooxygenase up-regulation.
