-
The invention discloses a diaryl-containing imidazole compound. The invention further discloses application of the diaryl-containing imidazole compound to preparation of drugs for preventing or treating Alzheimer's disease. The inventor screens butyrylcholine esterase and IDO1 as carriers for inhibiting the activity to evaluate the effect of the diaryl imidazole compound to treat Alzheimer's disease, and finds that the diaryl imidazole compound has good in vitro activity, and can be further developed as a precursor substance for performing the Alzheimer's disease resistant effect by inhibitingthe activity of cholinesterase. (The formula is shown in the description).

- Synthesis and evaluation of 2-(2-arylmorpholino)ethyl esters of ibuprofen hydrochlorides as COX-2 and serotonin reuptake inhibitors
-
Based on the positive effects of COX-2 inhibitors on depressive symptoms and the desirable physicochemical and biological properties of the morpholine group, a series of novel 2-(2-arylmorpholino)ethyl esters of ibuprofen hydrochlorides were designed, synthesized, and tested for their COX-2 inhibitory and serotonin reuptake inhibitory activities in vitro. The structure-activity relationships of the 2-(2-arylmorpholino)ethyl esters of ibuprofen hydrochlorides as dual COX-2 and serotonin reuptake inhibitors were determined and discussed in detail. The biological assays indicated that five of the compounds possess good COX-2 selectivity (selectivity index COX-1/COX-2 42.8-158.1). The compound 2-[2-(4-benzyloxyphenyl)morpholino]ethyl 2-(4-iso-butylphenyl)-propanoate hydrochloride (1k) shows better COX-2 inhibitory activity (IC50 = 0.78 μM) than ibuprofen (IC 50 = 7.6 μM), and it simultaneously possesses favorable serotonin reuptake inhibitory activity. A series of novel 2-(2-arylmorpholino)ethyl esters of ibuprofen were tested for their COX-2 inhibitory and serotonin reuptake inhibitory activities in vitro. Most of the compounds possess good COX-2 selectivity. Compound 1k shows better COX-2 inhibitory activity than ibuprofen and possesses favorable serotonin reuptake inhibitory activity. According to the results of the biological assays, 2-arylmorpholine-substituted ibuprofen could be used as a core structure to design novel dual COX-2 and serotonin reuptake inhibitors.

- Design, synthesis and biological evaluation of 2-(2-aryl-morpholino-4-yl) ethyl esters of indomethacin as potential cyclooxygenase-2 (COX-2) inhibitors
-
A number of novel 2-(2-arylmorpholino-4-yl)ethyl 1-(4-chlorobenzoyl)-5- methoxy-2-methyl-1H-indol-3-acetate hydrochlorides were synthesized and tested for their cyclooxygenase (COX-1 and COX-2) inhibition properties in vitro. Many of these compounds exhibited moderate to good selective COX-2 inhibition, and subtle structural changes in the substituents on the side chain of the ester moiety altered the inhibitory properties significantly. 2-[2-(4-Butoxyphenyl) morpholino-4-yl]ethyl 1-(4-chlorobenzoyl)-5-methoxy-2-methyl-1H-indol-3-acetate hydrochloride (1f), showed good selective COX-2 inhibitory activity (Selective index (SI) 182), which is comparative with celecoxib (SI 214), a COX-2 inhibitor of diarylpyrazoles. While 2-[2-(2,4-dichloro-5-fluorophenyl)morpholino-4-yl] ethyl 1-(4-chlorobenzoyl)-5-methoxy-2-methyl-1H-indol-3-acetate hydrochloride (1g), showed greater selective COX-2 inhibitory activity (SI 358) than celecoxib. Both compounds were identified as compromising derivatives in this class to reduce the side effects generated by nonsteroidal anti-inflammatory drugs (NSAIDs) indomethacin.

- Synthesis, spectral characterization and biological evaluation of a novel series of 6-arylsubstituted-3-[2-(4-substitutedphenyl)propan-2-yl]-7H-[1,2,4] triazolo[3,4-b][1,3,4]thiadiazines
-
On account of the reported anticancer activity of triazolothiadiazines, we have synthesized a novel series of 6-arylsubstituted-3-[2-(4-substitutedphenyl) propan-2-yl]-7H-[1,2,4]triazolo[3,4-b][1,3,4]thiadiazines and tested for in-vitro cytotoxicity by trypan blue exclusion and MTT assay. These compounds were also evaluated for their in-vivo anthelmintic activity, as well as in-vitro antimicrobial studies. Amongst the tested compounds, the compound 7j was the most promising cytotoxic agent with IC50 value of 10.54 μM in MCF-7 cells. The compounds 7l and 7q exhibited excellent anthelmintic activity. The compounds 7d, 7f, 7j, 7l, 7o, 7p and 7r showed good antibacterial activity, whereas compounds 7e and 7k exhibited excellent antifungal activity. The structures of newly synthesized compounds were characterized by IR, 1H NMR, 13C NMR and LCMS analysis.

-
A series of arylthioureas (1), aromatic aldehyde thiosemicarbazones (2) and 5-aryl-2-furfuraldehyde thiosemicarbazones (3) were condensed with 2,4-dichloro-5-fluorophenacyl bromide to yield respective arylaminothiazoles, arylidene/5-aryl-2-furfurylidene hydrazinothiazoles (4). The newly synthesized compounds were characterized by IR, 1H-NMR and mass spectral studies. These compounds were also screened for their antibacterial and anti-inflammatory activities. Two of the newly synthesized compounds showed anti-inflammatory activity comparable with that of Ibuprofen.
