Antitumor Activity of C-phycocyanin from Arthronema africanum (Cyanophyceae)
Pure C-phycocyanin (C-PC) was isolated from Arthronema africanum to evaluate its potential antitumor effects in vivo and in vitro. Experimental myeloid Graffi tumor in hamsters was used as a model. The cell proliferation assay showed that C-PC treatment, at concentration of 100 μg mL for 24 h, significantly inhibited the growth of Graffi tumor cells (51.4% viability). Agarose gel electrophoresi...
متن کاملMembrane Metabolites of Arthronema Africanum Strains from Extreme Habitats
Two strains of scarcely studied Arthronema africanum (Cyanoprokaryota), originating from two desert habitats in Kuwait and Kathmandu (Nepal) were investigated. Both algae possess good adaptability and grow in a wide range of temperatures and light intensities. The lethal temperature for the Kuwait strain was 50 ± 1 oÑ while the one of Nepal origin died at 47 ± 1 oÑ. The content of phycobiliprot...
متن کاملCleavage of phycocyanobilin from C-phycocyanin.
The chromophore of C-phycocyanin, phycocyanobilin, was cleaved from the protein with methanol, concentrated hydrochloric acid, or subtilisin BPN’. The pigments obtained were converted to their dimethyl esters and purified by preparative high pressure liquid chromatography and examined for purity by analytical high pressure liquid chromatography on silica gel. They were characterized by proton t...
متن کاملIn-vitro Antitumor Activity and Antifungal Activity of Pennogenin Steroidal Saponins from paris Polyphylla var. yunnanensis
Paris polyphylla Smith var. yunnanensis, has been used in traditional Chinese medicine for its antibiotic and anti-inflammatory properties; in addition it has been used to cure liver cancer in particular. In this current study, β-ecdysterone (1) and three pennogenin steroidal saponins (2-4) were isolated from the EtOH extract of Paris polyphylla var. yunnanensis, and then tested for their antit...
