, (2018/08/29)
Disclosed are 3-indolyl furanoid compounds which are useful as potent anti-inflammatory agents and prevent gastric ulcer by inhibiting matrix metalloproteinase-9 (MMP-9) expression in gastric mucosal layer. For example, disclosed is a compound of formula 1, wherein: R1 to R6 is selected from H, OH, CH3, OCH3, Br, Cl, Ph or o-OHC6H4, OCH2—CH═CH2, or OCH2CH2CH3, and R1 to R6 is having at least one substituent with alkyl, aryl and heteroaryl groups other than H, wherein the carbon in alkyl, aryl and heteroaryl is in the range of C1 to C8. Various embodiments relate to representative compounds of Formula 1 and method of preparation thereof. Further embodiments relates to the use of representative compounds of Formula 1 in treating diseases associated with gastric ulcer and other inflammatory diseases. A noted feature of an embodiment is the IC50 value of 50 μM of one of the 3-indolyl furanoids.

A new simple catalytic system consisting of copper-aluminium and hydrotalcite (CuAl-HT) has been developed using a facile one-pot method without harm to the environment. The catalyst was characterized using TEM, XRD and XPS. It could be used as an efficient catalyst for the synthesis of both indole and phenyl ether. As expected, the catalyst afforded high catalytic activity for the selective synthesis of indole via intramolecular dehydrogenative N-heterocyclization of 2-(2-aminophenyl)ethanol. Meanwhile, it also exhibited superior catalytic properties for an Ullmann-type coupling reaction to synthesise phenyl ether from iodobenzene and phenol. The CuAl-HT catalyst showed higher activity than conventional catalysts based on copper and could be recycled several times with stable catalytic activity. This procedure has real economic advantages since no expensive materials were used.

This study is focused on a new series of benzylindole derivatives with various substituents at the benzene-fused ring, suggested by our 3D pharmacophore model developed for HIV-1 integrase inhibitors (INIs). All synthesized compounds proved to be active in the nanomolar range (6-35 nM) on the strand-transfer step (ST). In particular, derivative 4-[1-(4-fluorobenzyl)- 5,7-dimethoxy-1H-indol-3-yl]-2-hydroxy-4-oxobut-2-enoic acid (8e), presenting the highest best-fit value on pharmacophore model, showed a potency comparable to that of clinical INSTIs GS 9137 (1) and MK-0518 (2). The binding mode of our molecules has been investigated using the recently published crystal structure of the complex of full-length integrase from the prototype foamy virus in complex with its cognate DNA (PFV-IN/DNA). The results highlighted the ability of derivative 8e to assume the same binding mode of MK-0518 and GS 9137.

In a search for inducers of neuronal differentiation to treat neurodegenerative diseases such as Alzheimer's disease, a series of indole fatty alcohols (IFAs) were prepared, 13c (n = 18) was able to promote the differentiation of neural stem cell derived neurospheres into neurons at a concentration of 10 nM. Analysis of the expression of the Notch pathway genes in neurospheres treated during the differentiation phase with 13c (n = 18) revealed a significant decrease in the transcription of the Notch 4 receptor.
