Histone deacetylases (HDACs) are attractive therapeutic targets for the treatment of cancer and other diseases. It has four classes (I-IV), among them especially class I isozyme are involved in promoting tumor cells proliferation, angiogenesis, differentiation, invasion and metastasis and also viable targets for cancer therapeutics. A novel series of coumarin-based benzamides was designed and synthesized as HDAC inhibitors. The cytotoxic activity of the synthesized compounds (8a-u) was evaluated against six human cancer cell lines including HCT116, A2780, MCF7, PC3, HL60 and A549 and a single normal cell line (Huvec). We evaluated their inhibitory activities against pan HDAC and HDAC1 isoform. Four compounds (8f, 8q, 8r and 8u) showed significant cytotoxicity with IC50 in the range of 0.53–57.59?μM on cancer cells and potent pan-HDAC inhibitory activity (consists of HDAC isoenzymes) (IC50?=?0.80–14.81?μM) and HDAC1 inhibitory activity (IC50?=?0.47–0.87?μM and also, had no effect on Huvec (human normal cell line) viability (IC50?>?100?μM). Among them, 8u displayed a higher potency for HDAC1 inhibition with IC50 value of 0.47?±?0.02?μM near equal to the reference drug Entinostat (IC50?=?0.41?±?0.06?μM). Molecular docking studies and Molecular dynamics simulation of compound 8a displayed possible mode of interaction between this compound and HDAC1enzyme.

A number of N-(2-(1H-indol-3-yl)ethyl)-2-oxo-2H-chromene-3-carboxamides were synthesized and tested against AChE and BuChE. The in?vitro assessment of the synthesized compounds 4a-o revealed that most of them had significant activity toward AChE. The SAR study demonstrated that the introduction of benzyloxy moiety on the 7-position of coumarin scaffold can improve the anti-AChE activity. The best result was obtained with 7-(4-fluorobenzyl)oxy moiety in the case of compound 4o, displaying IC50value of 0.16?μM. Based on the docking study of AChE, the prototype compound 4o was laid across the active site and occupied both peripheral anionic site (PAS) and catalytic anionic site (CAS).

(Chemical Equation Presented) A new series of 3-acyl-6,7,8-substituted coumarin derivatives has been synthesized in high yields (79-99%) and characterized by means of elemental analysis, mass spectrometry, IR, and 1H NMR spectroscopy. We examined with particular attention the presence of an acyl group at position 3 (ethyl ester, carboxylic acid, and acyl chloride), and of a hydroxyl group at position 7 or a functionalized one like benzyloxy or phthalimido. The hydroxyl group has been modified by an etherification in presence of crown ether with substituted benzyl bromide or chloride to evaluate the influence on chemical characteristics and lipophilicity of coumarin nucleus. Halogens (Cl, Br) and methyl group were introduced in position 6 and 8 of the coumarin ring, respectively, in order to study their effect on reaction feasibility. Some of these 3-acyl derivatives have been recently assayed as MAO inhibitors and as intermediates (i.e. reactive chloride derivative) to design new anti-Helicobacter pylori agents.

A novel class of selective anti-Helicobacter pylori agents, 2-oxo-2H-chromene-3-carboxamide derivatives, were prepared and evaluated for their anti-bacterial activity. All synthesized compounds showed little or no activity against different species of Gram-positive and Gram-negative bacteria and against various strains of pathogenic fungi. Some of them exhibited a potent and specific inhibitory effect on the growth of H. pylori, including metronidazole-resistant strains, in the 0.0039-16 μg/mL MIC range. A cytotoxic screening by the Trypan blue dye exclusion assay was also carried out on the most active compounds as anti-H. pylori agents. Among the derivatives examined for their cytotoxic potential, a number of them induced low cytotoxic effects.
