Marine algae can serve as sources of bioactive compounds and currently have been shown their potential biological and pharmaceutical applications. Marine algae lectins have been shown to be effective at controlling inflammatory processes. This work aimed to analyze the immunostimulatory properties of lectins from the marine algae Solieria filiformis (SfL),(More)
Cramoll 1,4 is a lectin extracted from Cratylia mollis Mart. seeds that has shown antitumor and lymphocyte mitogenic activities in other studies. The aim of this work was to investigate, in vitro, the immunomodulatory activity of Cramoll 1,4 on experimental cultures of mice lymphocytes through cytotoxic assays, nitric oxide (NO) concentrations and IL-10 and(More)
Cramoll 1,4 is a lectin extracted from seeds of Cratylia mollis Mart. Many assays have shown the cytokine release activity and pro-inflammatory profile of this lectin. Here, we used Cramoll 1,4 in the treatment of cutaneous wounds in normal and immunocompromised mice for available your cicatricial power. Surgical wounds were treated daily with a topical(More)
Parkia pendula seed lectin was used to treat cutaneous wounds of normal and immunocompromised mice, inducing cicatrization. Methotrexate (0.8 mg/kg/week) was used as immunosuppressive drug. Wounds were produced in the dorsal region (1 cm(2)) of female albino Swiss mice (Mus musculus), health and immunocompromised. Wounds were daily topically treated with(More)
We modified the thiazolidinic ring at positions N3, C4, and C5, yielding compounds 6-24. Compounds with a phenyl at position N3, 15-19, 22-24, exhibited better inhibitory properties for cruzain and against the parasite than 2-iminothiazolidin-4-one 5. We were able to identify one high-efficacy trypanocidal compound, 2-minothiazolidin-4-one 18, which(More)
Cramoll 1,4 is a lectin with specific glucose/mannose binding, which is extracted from seeds of Cratylia mollis Mart. Many assays have shown the cytokine expression activity and anti-inflammatory profile of this lectin. The aim of this study was to evaluate the immunostimulatory response, in vitro, of splenocytes in mice previously inoculated, in vivo, with(More)
The mitogenic lectins are invaluable tools to study the biochemical changes associated with lymphocyte activation and proliferation of various immune cells. Rachycentron canadum lectin (RcaL) was detected and purified from serum of cobia fish. The aim of this study was to evaluate the proliferative response and cytokine production in splenocytes of mice in(More)
Lectins are proteins or glycoproteins with the ability to link to carbohydrates at the cell surface in a specific and reversible manner. Studies have showed that lectins are demonstrate immunomodulatory and antitumor agents. This study aims to evaluate the effect of lectin extracted from the seeds of Canavalia brasiliensis (ConBr) on murine melanoma B16F10(More)
An increasing number of biological activities presented by medicinal plants has been investigated over the years, and they are used in the search for new substances with lower side effects. Eugenia uniflora L. and Eugenia malaccensis L. (Myrtaceae) have many folk uses in various countries. This current study was designed to quantify the polyphenols and(More)
Alpinia purpurata is an ornamental crop known as a source of bioactive molecules. This is the first study to report isolation of a lectin (carbohydrate-binding protein) from A. purpurata inflorescences (ApuL). The immunomodulatory potential of ApuL was evaluated by investigating its effects on the production of cytokines and release of nitric oxide by human(More)
