Application of monocarbonyl curcumin compound in preparation of medicine for preventing and treating periodontitis

The invention belongs to the technical field of medicines, and particularly relates to application of a specific monocarbonyl curcumin analogue in preparation of a medicine for preventing and treating periodontitis. Experiments prove that the monocarbonyl curcumin analogues not only can play a better anti-oxidation protection role by activating an Nrf2/HO-1 signal channel, but also can play an anti-inflammatory role by inhibiting release of inflammatory factors TNF alpha and IL1-beta, so that the monocarbonyl curcumin analogues have a remarkable prevention and treatment effect on rat periodontitis, have good potential value and significance for prevention and treatment of periodontitis, and have a good research and development prospect.

Synthesis and antiproliferative activity of cyclic arylidene ketones: a direct comparison of monobenzylidene and dibenzylidene derivatives

Abstract To give further insight into the influence of the structural modifications of enones and dienones on their antiproliferative properties, 25 derivatives of enones: (E)-2-benzylidene-1-cyclohexanones, (E)-2-benzylidene-1-tetralones, (E)-2-benzylidene-1-indanone, and dienones: (E,E)-2,5- or 2,6-dibenzylidene-1-cyclanones, (E,E)-3,5-dibenzylidene-4-piperidones were synthesized using a newly developed "one-pot" synthetic method. Due to the fact that all of them have the same aryl substituents (phenyl or 4-chlorophenyl) in the arylidene moiety, it is possible to compare the relevant contribution of the single-point structural modifications (type of ring or N-substitution) on their potency on the basis of their IC 50 values. Their antiproliferative activity was evaluated against the following four human adherent cancer cell lines: HeLa, A431, A2780, and MCF7. The cytotoxicity screen has revealed that the dibenzylidene dienones in general dominate the monobenzylidene enones in this respect. The nitrogen-containing heterocyclic dienones at the same time displayed higher inhibitory properties toward these human carcinoma cell lines compared with their homocyclic dienone analogs. One of the eight newly prepared 4-piperidone derivatives, N-(γ-oxobutyl)-(E,E)-3,5-bis(p-chlorobenzylidene)-4-piperidone is as potent a cell growth inhibitor (IC 50 of 0.438-1.409 μM) as the N-methyl-(E,E)-3,5-bis(p-chlorobenzylidene)-4-piperidone (IC 50 of 0.447-1.048 μM), one of the most active among the previously described compounds in this series. Catalytic hydrogen-transfer isomerization of compounds with two exocyclic benzylidene double bonds to derivatives with endocyclic double bonds results in the complete loss of antiproliferative activity. The structural modifications and 50 % inhibitory concentration (IC 50) values resulted in correlations which can promote the design of more potent derivatives of the 4-piperidone dienones.

Amino functionalized mesoporous silica decorated with iron oxide nanoparticles as a magnetically recoverable nanoreactor for the synthesis of a new series of 2,4-diphenylpyrido[4,3-d]pyrimidines

(Fe2O3)-MCM-41-nPrNH2 as a magnetically recoverable nanoreactor, was prepared through the reaction of (Fe 2O3)-MCM-41 with 3-aminopropyltriethoxysilane in refluxing dry toluene. The catalyst with 10 wt% of loaded iron oxide nanoparticles was found to be a highly efficient nanocatalyst for the synthesis of a new class of 2,4-diphenylpyrido[4,3-d]pyrimidines under solvent free conditions in high to quantitative yields. By using an external magnet the catalyst was recovered and reused several times without any loss of efficiency. The prepared catalyst was characterized by transmission electron microscopy (TEM), Fourier transform infrared (FT-IR) spectroscopy, X-ray powder diffraction (XRD), and nitrogen physisorption measurements.
