Chemical constituents and antiproliferative effects of cultured Mougeotia nummuloides and Spirulina major against cancerous cell lines
AbstractIn this study, the effect ofMougeotia nummuloidesandSpirulina majoron Vero cells (African green monkey kidney), C6 cells (rat brain tumor cells) and HeLa cells (human uterus carcinoma) was investigatedin vitro. The antiproliferative effect of the methanol extract ofM. nummuloidesandS. majorcompared with 5-fluorourasil (5-FU) and cisplatin was tested at various concentrations using the BrdU Cell Proliferation ELISA. BothM. nummuloidesandS. majorextracts significantly inhibited the proliferation of Vero, HeLa and C6 cancer cell lines with IC50and IC75values. TheM. nummuloidesextract exhibited higher activity than 5-FU and cisplatin on Vero and C6 cells at high concentrations. TheS. majorextract revealed better antifproliferative activity than standards against Vero cells at 500 μg/mL. The compounds of methanol extracts were determined by GC-MS after the silylation process. Trehalose, monostearin and 1-monopalmitin were detected as major products in theM. nummuloidesextract where as in theS. majorextract; monostearin, 1-monopalmitin and hexyl alcohol were the main constituents.
