Over the last decade, there has been substantial interest in the use of melatonin (MLT) and MLT-like compounds in the treatment of several diseases. MLT can scavenge different reactive oxygen species and can also stimulate the synthesis of antioxidant enzymes. Our ongoing study relies on changing the groups in the different modifiable sites of the indole ring to increase the antioxidant activity. In this study a new approach for substitution of indole ring as indole based MLT analogue was proposed. We report the synthesis and characterization of a series of new indole-7-aldehyde hy-drazide/hydrazone derivatives as indole-based MLT analogues. Anticancer potential of the compounds were evaluated both by their antioxidant and CYP1 inhibitory activities. In vitro antioxidant capacity of the compounds was investigated both in a cell-based (DCFH assay) and a cell-free (DPPH assay) assay. Potential inhibitory effects of the compounds on CYP1 catalytic activity were investigated via EROD assay. Cytotoxic activity of the compounds was further evaluated by the MTT assay in CHO-K1 cells. MLT analogues having an o halogenated aromatic moiety exhibited effective antioxidant properties without having any cytotoxic effect. In conclusion, MLT derivatives represent promising scaffolds for discovery of effective antioxidant agents.

Cancer continues to be the second leading cause of death worldwide. Discovery of novel therapeutic agents has crucial importance for improvement of our medical management capabilities. Dysregulation of the MET receptor tyrosine kinase pathway plays an important role in cancer progression, making this receptor an attractive molecular target for anticancer drug discovery. In this study, twenty-seven 3,4-dihydropyrimidin-2(1H)-one C5 amide derivatives were synthesized and their cancer cell growth inhibitory activity was examined against MCF-7, HT-29 and MOLT-4 cells and also NIH/3T3 non-cancer cells by MTT assay. The antipmliferative effect of the most potent derivatives were tested against MET-dependent EBC-1 and MKN-45, lung and gastric cancer cell lines, respectively. MET kinase inhibition was measured by a Homogenous Time Resolved Fluorescence (HTRF) Assay. The influence of the test compounds on cell cycle was examined by RNase/PI flow cytometric assay. A number of compounds exhibited considerable antiproliferative effects against breast and colon cancer and leukemia cell lines, relatively sparing non-cancer cells. Some derivatives bearing benzothiazolyl carboxamide moiety at C5 position (15, 21, 23, 31, and 37) showed the highest activities with IC50 values as low as 10.9 mu M. These compounds showed antiproliferative effects also against MET-amplified cells and dose-dependently inhibited MET kinase activity. They also induced G0/G1 cell cycle arrest at lower doses and apoptosis at higher doses. Molecular docking and dynamics simulation studies confirmed the interaction of compound 23 with the active site of the MET receptor. These findings demonstrate that 3,4-dihydropyrimidin-2(1H)-one analogues may represent promising targeted anticancer agents.

alpha-Methylene-delta-valerolactone (MVL) is a bifunctional monomer comprising of a highly stable six-membered delta-valerolactone ring and highly reactive C(sic)C bond. Previously, the vinyl-addition polymerization (VAP) product, namely P(MVL)(VAP), has been formed exclusively. In this study, this conventional chemoselectivity is reversed, wherein organic catalysts are used to enable the first ring-opening polymerization (ROP) of MVL, exclusively affording a metal-free, unsaturated polyester, namely P(MVL)(ROP). This challenging goal is achieved by investigating different catalysts, initiators, and reaction conditions. In addition, the formation of two polymers, namely P(MVL)(ROP) and P(MVL)(VAP), is easily regulated by varying the polymerization solvent. The resulting P(MVL)(ROP) can be easily post-functionalized to form crosslinked or sulfurized materials; notably, it can be almost completely converted into its monomer thermochemically.

A novel series of bicyclic fluorescent heterocalixarenes – C-alkyl coumarin[4]arenes – with built-in chirality has been synthesized successfully in excellent yields under well-optimized, improved reaction conditions. Further, structural elaboration (including pi-extension) of coumarin[4]arenes has been demonstrated by using Pd-catalyzed Suzuki and Sonogashira cross-coupling methods. All of these macrocycles are shown to possess averaged C-4-symmetric conformation in solution as opposed to the coumarin[4]arene tetratriflate derivative of C-2 symmetry in the solid state. Finally, the macrocyclic coumarin[4]arenes reveal UV/near-UV absorption and visible blue emission in solution. Such a visible blue luminescence of this macrocycle highlights its potential for sensing, bioimaging, and light-emissive applications.

The gram-scale synthesis of important flavoring ketones via alkylation of acetoacetic ester on substituted benzylic carbon followed by decarboxylation using a heterogeneous, commercial, solid acid catalyst is reported. The flavoring ketones were synthesized by the alkylation of acetoacetic ester, which proceeds through an S(N)1-type reaction to generate an alkylated (beta-ketoester) intermediate at the benzylic carbon, which is decarboxylated under the acidic condition. Among the solid acid catalysts used, Amberlyst-15 was found to be the best catalyst under the solvent-free condition. This protocol was successfully employed for the synthesis of various flavoring ketones such as raspberry ketone and ginger ketone with almost complete conversion and 82% isolated yield. The para-donating groups on the benzylic alcohol showed a high rate of reaction. The catalyst was easily recovered and reused 6 times without losing its activity and selectivity. Moreover, this reaction was demonstrated at a 10 g scale, which implicated the potential applicability of the protocol in the industry.
