Since the major approach in searching for potential anticancer agents over the last 50 years has been based on selective cytotoxic effects on mammalian cancer cell lines, cell-based methods for cytotoxicity are described and compared. The sulphorhodamine B (SRB) assay is described in detail as the preferred method and also a novel approach has been developed which is based on the hypothesis tha...

Lichen phenolic compounds exhibit antioxidant, antimicrobial, antiproliferative, and cytotoxic activities. The purpose of this study was to evaluate the anticancer activity of lecanoric acid, a secondary metabolite of the lichen Parmotrema tinctorum, and its derivatives, orsellinates, obtained by structural modification. A cytotoxicity assay was carried out in vitro with sulforhodamine B (SRB) ...

Background: Natural products have gained importance recently for the treatment of obesity and its complications, partly because of the side effects of modern drugs.Hence, we aimed to study and compare the effect of varying concentrations of Momordicacharantiaon adipogenesis and adipolysis using 3T3-L1 pre-adipocyte cell lines. Methods: 3T3-L1 pre-adipocytes were procured from the National Ce...

BACKGROUND The aim of this study was to investigate the effects of methionine depletion with cytotoxic agents that are potentially influenced by depletion of methionine, and are known to have a role in CNS tumour treatments for children. MATERIALS AND METHODS Cytotoxicity studies and synergistic interactions were assayed by SRB assay. Glutathione levels were assayed by HPLC after derivatizati...

Heteronemin is a bioactive marine sesterterpene isolated from the sponge Hyrtios sp. Previous reports have shown that heteronemin possesses anticancer activity. Here, heteronemin displayed cytotoxic effects against three human cancer cell lines (A549, ACHN, and A498) and exhibited potent activity in A498 human renal carcinoma cells, with an IC₅₀ value of 1.57 μM by MTT assay and a GI50 value of...

Anticancer potential of Piper longum fruit against human cancer cell lines (DU-145 prostate, A549 lung, THP-1 leukemia, IGR-OVI-1 ovary and MCF-7 breast) as well as its in vitro and in vivo biochemical efficacy in A1Cl3-induced hepatotoxicity were evaluated in the rats. Dried samples were extracted with several solvents using soxhlet apparatus. Flavonoid content in chloroform, benzene, ethyl al...

OBJECTIVE This study aimed to investigate the cytotoxicity, apoptosis induction, and mechanism of action of steviol on human breast cancer cells (Michigan Cancer Foundation-7 [MCF-7]). MATERIALS AND METHODS Sulforhodamine-B assay was performed to analyze cytotoxic potential of Steviol whereas flow cytometer was used to analyze cell cycle, apoptosis, and reactive oxygen species generation. R...

BACKGROUND The role of plants for discovery of therapeutic potential accentuates the need to know their biological attributes. The present study aims to comprehend the biological attributes of Rhus punjabensis, an unexplored traditional medicinal plant. METHODS Leaf and stem extracts of R. punjabensis prepared in 11 different organic solvents are evaluated for multimode antioxidant potential,...

Objective: This study is to investigate the antioxidant and antitumor effects of the extract fractions of the Ferula sinkiangensis K. M. Shen. Methods: Four different fractions of the Ferula sinkiangensis K. M. Shen were obtained by the extraction with petroleum ether, ethyl acetate, n-butanol, and methanol, respectively, which were used to treat the HCT116, Caco-2, HepG2, and MFC cells. Free r...

BACKGROUND Hepatocellular carcinoma (HCC), the most common type of liver cancer accounts for more than one million deaths worldwide. Current treatment modality for HCC is marginally effective. Plants belonging to Mistletoe family (Loranthaceae) have been used in chemotherapy for many years. The present study was aimed at exploring the anti-proliferative, pro-oxidant and pro-apoptotic potential ...
