Biological Activity of Picroside I

DescriptionPicroside I is a hepatoprotective agent which is reported to be antimicrobial and used against hepatitis B. It has antioxidant, and anti-inflammatory activities, it may be the valuable anti-invasive drug candidates for cancer therapy by suppressing Collagenases and Gelatinases. Picroside I can enhance basic fibroblast growth factor(bFGF)-, staurosporine- or dbc-mitogen-activated protein (MAP)-induced neurite outgrowth from PC12D cells.

Picrosides I and II, selective enhancers of the mitogen-activated protein kinase-dependent signaling pathway in the action of neuritogenic substances on PC12D cells.[Pubmed: 12151059]

Life Sci. 2002 Aug 30;71(15):1821-35.


METHODS AND RESULTS:
Picroside I and Picroside II caused a concentration-dependent (> 0.1 microM) enhancement of basic fibroblast growth factor (bFGF, 2 ng/ml)-, staurosporine (10 nM)- and dibutyryl cyclic AMP (dbcAMP, 0.3 mM)-induced neurite outgrowth from PC12D cells. Furthermore, picrosides-induced enhancements of the bFGF-action were markedly inhibited by GF109203X (0.1 microM), a protein kinase C inhibitor. The expression of phosphorylated MAP kinase was markedly increased by bFGF (2 ng/ml) and dbcAMP (0.3 mM), whereas that was not enhanced by staurosporine (10 nM). Picrosides had no effect on the phosphorylation of MAP kinase induced by bFGF or dbcAMP and also unaffected it in the presence of staurosporine. These results suggest that Picroside I and Picroside II enhance bFGF-, staurosporine- or dbcAMP-induced neurite outgrowth from PC12D cells, probably by amplifying a down-stream step of MAP kinase in the intracellular MAP kinase-dependent signaling pathway.
CONCLUSIONS:
Picroside I and Picroside II may become selective pharmacological tools for studying the MAP kinase-dependent signaling pathway in outgrowth of neurites induced by many kinds of neuritogenic substances including bFGF.

In vivo

Antiinflammatory activity of the iridoids kutkin, picroside-1 and kutkoside from Picrorhiza kurrooa[Reference: WebLink]

Phytother. Res., 1993, 7(6):402-7.

Powdered roots of Picrorhiza kurrooa (PK), its alcoholic extract (AEPK) and active constituents kutkin, Picroside I and kutkoside demonstrated antiinflammatory activity (AIA) in a variety of test models. Significant AIA was recorded in adjuvant-induced and formaldehyde arthritis in rats and mice. In carrageenan-induced oedema inhibitory activity was remarkably enhanced upon intraperitoneal treatment in rats and mice. Kutkin exhibited significant action in dextran-induced oedema in rats. It inhibited acetic acid induced vascular permeability in mice and leucocyte migration in rats. Kutkin lacked any analgesic, antipyretic or ulcerogenic effect.

Protocol of Picroside I

Kinase Assay

Picroliv, picroside-I and kutkoside from Picrorhiza kurrooa are scavengers of superoxide anions.[Pubmed: 1321626]

Biochem Pharmacol. 1992 Jul 7;44(1):180-3.

Picroliv, the active principle of Picrorhiza kurrooa, and its main components which are a mixture of the iridoid glycosides, Picroside I and kutkoside, were studied in vitro as potential scavengers of oxygen free radicals.
METHODS AND RESULTS:
The superoxide (O2-) anions generated in a xanthine-xanthine oxidase system, as measured in terms of uric acid formed and the reduction of nitroblue tetrazolium were shown to be suppressed by picroliv, Picroside I and kutkoside. Picroliv as well as both glycosides inhibited the non-enzymic generation of O2- anions in a phenazine methosulphate NADH system. Malonaldehyde (MDA) generation in rat liver microsomes as stimulated by both the ascorbate-Fe2+ and NADPH-ADP-Fe2+ systems was shown to be inhibited by the Picroliv glycosides. Known antioxidants tocopherol (vitamin E) and butylated hydroxyanisole (BHA) were also compared with regard to their antioxidant actions in the above system. It was found that BHA afforded protection against ascorbate-Fe(2+)-induced MDA formation in microsomes but did not interfere with enzymic or non-enzymic O2- anion generation; and tocopherol inhibited lipid peroxidation in microsomes by both prooxidant systems and the generation of O2- anions in the non-enzymic system but did not interfere with xanthine oxidase activity.
CONCLUSIONS:
The present study shows that picroliv, Picroside I and kutkoside possess the properties of antioxidants which appear to be mediated through activity like that of superoxide dismutase, metal ion chelators and xanthine oxidase inhibitors.

Cell Research

Iridoid glycosides-Kutkin, Picroside I, and Kutkoside from Picrorrhiza kurroa Benth inhibits the invasion and migration of MCF-7 breast cancer cells through the down regulation of matrix metalloproteinases 1st Cancer Update[Reference: WebLink]

Arab. J. Chem. 2011, 6(1):49-58.

Aim of the study Here, MCF-7 cell lines (Human breast cancer) were used to test whether P. kurroa extract (PE) and its isolated iridoid glycosides Picroside I (PS), Kutkoside (KS), and Kutkin (KT) exerts the anti-invasion activity via down-regulation of the expression of matrix metalloproteinases (MMPs). MMPs play an important role in solid tumor invasion and migration.
METHODS AND RESULTS:
The activity and expression of gelatinases (MMP-2 and MMP-9) and collagenases (MMP-1 and MMP-13), protein, and mRNA were detected by gelatin zymography, and RT-PCR. The migratory and invasive capacities of MCF-7 cell lines were measured by the wound scratch migration assay. The preliminary cytotoxicity testing was done by MTT assay and propidium iodide staining. Further the inhibition of inflammatory mediators was also done by quantification of nitrite inflammatory mediators. The study showed that PE and its isolated iridoids glycosides PS, KS, and KT exhibited considerable cytotoxic potential in a dose-dependent manner. Further PE, PS, KS, and KT inhibited MCF-7 cell invasion and migration, and decreased MMP-2, 9 and MMP-1, 13 activities. Furthermore, PS, KS, and KT reduced MMPs expression at protein and mRNA levels, and suppression of the inflammatory mediators was also exhibited.
CONCLUSIONS:
Our results suggest that PS, KS, and KT may be the valuable anti-invasive drug candidates for cancer therapy by suppressing Collagenases and Gelatinases. PS, KS, and KT showed good results in comparison with PE. PS and KS exhibit almost comparable down regulation while KT exhibited maximum suppression of invasion, migration, and expression of MMPs.

A proposed biosynthetic pathway of picrosides linked through the detection of biochemical intermediates in the endangered medicinal herb Picrorhiza kurroa.[Pubmed: 23696248]

Picrorhiza kurroa Royle ex Benth is an important medicinal herb used in the preparation of several herbal drug formulations due to the presence of Picroside I (P-I) and picroside-II (P-II) along with other iridoid-glucosides derivatives. The endangered status of P. kurroa coupled with lack of information on biosynthesis of Picroside Iand P-II necessitate deciphering the biosynthetic pathway for picrosides.
METHODS AND RESULTS:
LC with electrospray ionisation (ESI) and quadrupole time of flight combined with MS/MS was used to detect intermediates and assemble the picrosides biosynthetic pathway in P. kurroa. The presence of catalpol and aucubin, the major backbone structures of picrosides, along with intermediate metabolites boschnaloside, bartsioside and mussaenosidic acid, was confirmed in ESI negative mode with pseudomolecular ion peaks, that is, m/z 361, m/z 343, m/z 345, m/z 329 and m/z 375 ions and their fragmentation patterns.
CONCLUSIONS:
The picrosides biosynthetic pathway is expected to provide a reliable platform towards understanding the molecular components (genes/enzymes) of Picroside I and P-II biosynthesis in P. kurroa for their eventual utilisation in various applications.

Picrosides I and II, selective enhancers of the mitogen-activated protein kinase-dependent signaling pathway in the action of neuritogenic substances on PC12D cells.[Pubmed:12151059]

Picrosides I and II caused a concentration-dependent (> 0.1 microM) enhancement of basic fibroblast growth factor (bFGF, 2 ng/ml)-, staurosporine (10 nM)- and dibutyryl cyclic AMP (dbcAMP, 0.3 mM)-induced neurite outgrowth from PC12D cells. PD98059 (20 microM), a potent mitogen-activated protein (MAP) kinase kinase inhibitor, blocked the enhancement of bFGF (2 ng/ml)-, staurosporine (10 nM)- or dbcAMP (0.3 mM)-induced neurite outgrowth by picrosides, suggesting that picrosides activate MAP kinase-dependent signaling pathway. However, PD98059 did not affect the bFGF (2 ng/ml)-, staurosporine (10 nM)- and dbcAMP (0.3 mM)-induced neurite outgrowth in PC12D cells, indicating the existence of two components in neurite outgrowth induced by bFGF, staurosporine and dbcAMP, namely the MAP kinase-independent and the masked MAP kinase-dependent one. Furthermore, picrosides-induced enhancements of the bFGF-action were markedly inhibited by GF109203X (0.1 microM), a protein kinase C inhibitor. The expression of phosphorylated MAP kinase was markedly increased by bFGF (2 ng/ml) and dbcAMP (0.3 mM), whereas that was not enhanced by staurosporine (10 nM). Picrosides had no effect on the phosphorylation of MAP kinase induced by bFGF or dbcAMP and also unaffected it in the presence of staurosporine.
