Journal ArticleDOI
C-Phycocyanin from Oscillatoria tenuis exhibited an antioxidant and in vitro antiproliferative activity through induction of apoptosis and G0/G1 cell cycle arrest.
Ramar Thangam,Veeraperumal Suresh,W. Asenath Princy,Mayan Rajkumar,Namasivayam Senthilkumar,Palani Gunasekaran,Ramasamy Rengasamy,Chinnathambi Anbazhagan,Krishnasamy Kaveri,Soundarapandian Kannan +9 more
TL;DR: CPC exhibited antioxidant and antiproliferative activity against human cancer cells through apoptosis; nuclear apoptosis induction was accompanied by G0/G1 phase arrest and DNA fragmentation, and CPC is a natural pigment with potential as an anticancer agent.
Journal ArticleDOI
Separation, purification and preliminary characterization of sulfated polysaccharides from Sargassum plagiophyllum and its in vitro anticancer and antioxidant activity
Veeraperumal Suresh,Namasivayam Senthilkumar,Namasivayam Senthilkumar,Ramar Thangam,Ramar Thangam,Mayan Rajkumar,Chinnathambi Anbazhagan,Ramasamy Rengasamy,Palani Gunasekaran,Soundarapandian Kannan,P. Palani +10 more
TL;DR: Results indicated that the anticancer activity of F2 could be related to its sulfate content, however, the antioxidant activities of F1–F3 were low at their tested concentrations.
Journal ArticleDOI
Isolation and characterization of macromolecular protein R-Phycoerythrin from Portieria hornemannii.
Namasivayam Senthilkumar,Veeraperumal Suresh,Ramar Thangam,Ramar Thangam,Chidambaram Kurinjimalar,Ganapathy Kavitha,Pitchai Murugan,Soundarapandian Kannan,Ramasamy Rengasamy +8 more
TL;DR: The preparative procedures of the R- PE extraction and purification established based on the experiments exhibit advantages and can offer a reference for R-PE preparation from other marine red macro-alga P. hornemannii.
Journal ArticleDOI
Further studies and biological activities of macromolecular protein R-Phycoerythrin from Portieria hornemannii.
Namasivayam Senthilkumar,Namasivayam Senthilkumar,Chidambaram Kurinjimalar,Ramar Thangam,Veeraperumal Suresh,Ganapathy Kavitha,Palani Gunasekaran,Ramasamy Rengasamy +7 more
TL;DR: Moderate to low antioxidant activities were observed in R-PE in relation to total antioxidant activities as well as characteristic apoptotic features like cell shrinkage, membrane blebbing and nuclear DNA fragmentation.
Journal ArticleDOI
Stabilization of mitochondrial and microsomal function of fucoidan from Sargassum plagiophyllum in diethylnitrosamine induced hepatocarcinogenesis.
Veeraperumal Suresh,Chinnathambi Anbazhagan,Ramar Thangam,Ramar Thangam,Dharmaraj Senthilkumar,Namasivayam Senthilkumar,Soundarapandian Kannan,Ramasamy Rengasamy,P. Palani +8 more
TL;DR: The inhibition of carcinogen metabolic activation indicates the anticancer activity of fucoidan in DEN induced liver cancer.
