A series of novel coumarin-based N-hydroxycinnamamide derivatives were designed and synthesized as histone deacetylase (HDAC) inhibitors. Most of the synthesized compounds showed potent HDAC inhibitory activity and significant antiproliferative activity a

A series of (3-hydroxypyridin-4-one)-coumarin hybrids were developed and investigated as potential multitargeting candidates for the treatment of Alzheimer's disease (AD) through the incorporation of iron-chelating and monoamine oxidase B (MAO-B) inhibition. This combination endowed the hybrids with good capacity to inhibit MAO-B as well as excellent iron-chelating effects. The pFe3+ values of the compounds were ranging from 16.91 to 20.16, comparable to more potent than the reference drug deferiprone (DFP). Among them, compound 18d exhibited the most promising activity against MAO-B, with an IC50 value of 87.9 nM. Moreover, compound 18d exerted favorable antioxidant activity, significantly reversed the amyloid-β1-42 (Aβ1-42) induced PC12 cell damage. More importantly, 18d remarkably ameliorated the cognitive dysfunction in a scopolamine-induced mice AD model. In brief, a series of hybrids with potential anti-AD effect were successfully obtained, indicating that the design of iron chelators with MAO-B inhibitory and antioxidant activities is an attractive strategy against AD progression.

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).

Two homologous series of mesomorphic esters containing coumarin nucleus have been synthesized and mesomorphic behaviour of their members studied.In series Ia (cholesteryl esters of 7-n-alkoxycoumarin-3-carboxylic acids), all the members exhibit enantiotropic cholesteric mesomorphism.The smectic phase commences from the hexyl derivative as a monotropic phase, octyl to hexadecyl derivatives are enantiotropic smectic.In series II , first five members are non-mesomorphic.Both smectic and nematic phases appear as monotropic phases from hexyl to octyl derivatives.The nonyl to dodecyl derivatives show monotropic smectic phase only.The last three members are enantiotropic smectic.Plots of transition temperatures against the number of carbon atoms in alkyl chain in series Ia behave in a normal manner whereas similar plots show an ascending tendency in series II.In series II, the smectic-nematic curve merges with the odd number curve of the nematic-isotropic transitions at the nonyl derivative.
