Triterpenoids as novel natural inhibitors of human cathepsin L.[Pubmed:25238076]
Chem Biodivers. 2014 Sep;11(9):1354-63.
Cathepsins L (catL) and B play an important role in tumor progression and have been considered promising therapeutic targets in the development of novel anticancer agents. Using a bioactivity-guided fractionation, a series of triterpenoids was identified as a new class of competitive inhibitors towards cathepsin L with affinity values in micromolar range. Among the 14 compounds evaluated, the most promising were 3-Epiursolic acid (3), 3-(hydroxyimino)oleanolic acid (9), and 3-(hydroxyimino)masticadienoic acid (13) with IC50 values of 6.5, 2.4, and 2.6 muM on catL, respectively. Most of the evaluated triterpenoids do not inhibit cathepsin B. Thus, the evaluated compounds exhibit a great potential to help in the design of new inhibitors with enhanced potency and affinity towards catL. Docking studies were performed in order to gain insight on the binding mode and SAR of these compounds.
Antiinflammatory activity and chemical composition of extracts of Verbena officinalis.[Pubmed:10960904]
Phytother Res. 2000 Sep;14(6):463-5.
In an attempt to locate the biologically active fraction(s) of the plant Verbena officinalis Linn. (Verbenaceae), a preliminary screening of successive petroleum ether, chloroform and methanol extracts of aerial parts for antiinflammatory activity using carrageenan paw oedema model was carried out. All three extracts were found to exhibit antiinflammatory activity with the chloroform extract being the most active. Chemical investigations of petroleum ether and chloroform extracts led to the isolation of beta-sitosterol, ursolic acid, oleanolic acid, 3-Epiursolic acid, 3-epioleanolic acid, and minor triterpenoids of derivatives of ursolic acid and oleanolic acids. Chromatographic purification of the methanol extract yielded two iridoid glucosides, verbenalin and hastatoside, a phenylpropanoid glycoside, verbascoside and beta-sitosterol-D-glucoside.
