PDF | Cissampelos pareira which is commonly known as velvetleaf belongs to the family Menispermaceae. Numbers of species are available all over the world . Cissampelos pareira f. emarginato-mucronata Chod. & Hassl. Synonym. Cissampelos pareira f. reniformis Chodat & Hassl. Synonym. Cissampelos pareira var. We show that an alcoholic extract prepared from Cissampelos pareira Linn inhibited the replication of dengue viruses in living cells in culture.
Traditional medicine-inspired approaches to drug discovery: To this end, extracts were prepared from Cipa plants collected during different seasons from multiple geographical locations within India. The authors are grateful to Prof.
Known or potential benefits of the species for humans, at a direct economic level, as instruments of education, prospecting, eco-tourism, etc. At a dose of 10 6 PFU given i.
As a standardized reference is not available to assess the efficacy of DENV inhibitory potency, PRNT data of monoclonal antibodies mAbs were used to decide on the cut-off value in the type-1 assay.
However, benefits to ecosystems not specific to humans are best treated under Risk statement what happens when the organism is removed. Further, it would be desirable to be able to inhibit the viruses both before as well as after entry into susceptible cells.
Additions to Asterinaceous Ascomycetes fungi in India Pareirx Cissampelos pareira Illustration Credit: The rest were effective at least against two other DENV serotypes. S1 Table Mean body weight and food intake of Wistar rats treated with Cipa extract. Where is the hope for drug discovery?
In this context, it also becomes important to assess if Cipa would have any effect on RBCs and platelets. In the context of antiviral screening, this assay had the following possible outcomes: Cell-based bioassays for antiviral screening The initial antiviral screening assay, designated as the type-1 assay, was based on the plaque reduction neutralization test PRNT described earlier for determining DENV-neutralizing antibody titres in sera [ 20 ].
Dengue disease predisposes some patients to hemorrhagic manifestations and tends to be associated with lowered platelet counts. Update on the global spread of dengue. Views Read Edit View history. A hallmark of severe dengue disease is the elevation of inflammatory cytokines which are implicated in triggering events that culminate in vascular permeability and haemorrhage [ 24 ].

Nani Daman, Daman Plot No. In a dengue-endemic resource-poor country as India, the C. Natural products in drug discovery. If you would like to support this site, please consider Donating. In the experiment, the results of which are summarized in Table 4Cipa extracts were prepared from plants obtained during the flowering season from four different locations, and evaluated using the type-1 assay described above.
Retrieved from ” https: Possible outcomes in the type-2 assay are as follows: Flora of Fergusson College campus, Pune, India: A Mini Review Desc: If you have any useful information about this plant, please leave a comment.
This observation has led drug pareiira to hypothesize that lowering viremia by 1—2 logs may be associated with a favourable prognosis [ 14 ]. Therefore, DENV infection preceded exposure to the herbal extract.
One of these, chosen for further study to assess its in vivo efficacy and clinical relevance, was found to be a promising candidate for further development as a pan-DENV inhibitory formulation.
Thiruvananthapuram District harbours more than 1, medicinal plants of which plants cissampekos hosts Author information Article notes Copyright and License information Disclaimer.
Analysis of these extracts revealed that the anti-DENV inhibitory cisssampelos is evident in plants collected during the flowering season of April to September [ 26 ].
Open in a separate window. Habitat in Napaulia, Buchnan-Hamilton. Introduction Dengue disease is a major public health concern around the world. These concerns were addressed in the following experiments. Plants shortlisted on this basis from the vast indigenous herbal bio-resource available in India were screened for anti-DENV activity. A type-1 assay was carried out in which DENV-3 was pre-incubated with serial dilutions of a Cipa extract.
The final possibility is that the extract would reduce the plaque count, indicating antiviral activity. After this, the samples were spun down, and the absorbance of the supernatant measured at nm to determine the extent of erythrocyte lysis. To assess any potential cytotoxicity, cells were exposed to the herbal extracts in the same concentration range in the absence of DENV infection. The blood samples, withdrawn from the Wistar rats given Cipa extract, described abovewere also analysed for erythrocyte cell counts.
Preliminary toxicological evaluation An exploratory toxicological study to assess any adverse effect of repeat dosing over a 1 week span with Cipa extract was carried out in Wistar rats.

The plant is very common in hedges at the foothills and up to c. Technology partner Strand Life Sciences. Groups of 5 adult Wistar rats were orally administered 4 ml 0. Another herb — Cyclea peltata is also used in the name of Patha.

Two, the Cipa extract could be the starting point for developing a carefully standardized herbal formulation for human use. For this, we used the AG mouse which has emerged in cissampells years as a promising dengue model [ 2127 ] for testing potential DENV inhibitors [ 28 ]. In the next set of experiments, whole blood from human volunteers was collected and platelets counts obtained before and after cissammpelos hours post-mixing with Cipa extract.
Flowers are small in size, pedicels filiform. As a result, all subsequent studies were carried out using the methanolic extracts. TX represents a control in which an equivalent aliquot of erythrocytes were treated with Triton X to achieve complete lysis.
