Product Description
Ankaflavin is found in Monascus-Fermented red rice and is an orally bioactive PPARγ agonist. Ankaflavin has a selective cell toxicity/cytotoxicity and causes apoptosis in cancer/tumor cells. Ankaflavin has anti~inflammatory, anti-cancer, anti-atherosclerotic and hypolipidemic effects.
Ankaflavin (CAS#: 50980-32-0) is a natural azaphilone yellow pigment derived from Monascus-fermented products (red yeast rice). It is an orally active PPARγ agonist with anti-inflammatory activity. Ankaflavin shows selective cytotoxic effects and induces cell death through apoptosis in cancer cells, but normal cells are not significantly harmed. It has anti-inflammatory, anti-cancer, anti-atherosclerotic, and hypolipidemic effects. The compound has potential therapeutic applications in treating inflammatory diseases and cancer, as well as in functional foods and nutraceuticals. Its molecular formula is C23H30O5 with a molecular weight of 386.48 g/mol.
Biological Activity I Assay Protocols (From Reference)
Targets
Ankaflavin primarily targets PPARγ (Peroxisome Proliferator-Activated Receptor Gamma), functioning as an orally active agonist. By activating PPARγ, it exerts anti-inflammatory, anti-cancer, anti-atherosclerotic, and hypolipidemic effects. The compound shows selective cytotoxicity towards cancer cells while sparing normal cells. Its anti-inflammatory activity involves modulation of inflammatory mediators. Ankaflavin induces apoptosis in cancer cells through PPARγ-mediated pathways.
ln Vitro
Ankaflavin (0-50 µg/mL, 48 h) exhibits cytotoxicity towards cancer cells, but normal cells are not significantly harmed [1]. Ankaflavin (0-30 µg/mL, 0-48 hours) in a dose- and time-dependent way stops the Hep G2 cell cycle in the sub-G1 phase [1]. In Hep G2 cells, ankaflavin (25 µg/mL, 48 h) causes apoptosis[1].
In vitro, Ankaflavin (0-50 µg/mL, 48 h) exhibits cytotoxicity towards cancer cells, while normal cells are not significantly harmed. The compound shows selective cytotoxic effects and induces cell death through apoptosis in cancer cells. Ankaflavin has anti-inflammatory, anti-cancer, anti-atherosclerotic, and hypolipidemic effects. Its PPARγ agonist activity has been confirmed in cell-based assays. The compound's anti-inflammatory activity is assessed by measuring inhibition of pro-inflammatory cytokine production.
ln Vivo
Ankaflavin (10 mg/kg; oral; given once daily for 28 days) may enhance pancreatic and liver function in addition to its antidiabetic and anti-inflammatory properties [2].
In vivo, Ankaflavin (10 mg/kg; p.o.; daily for 28 days) shows antidiabetic and anti-inflammatory activity, improves liver function and pancreatic function. The compound is orally active and has been studied in animal models for its anti-inflammatory, anti-cancer, anti-atherosclerotic, and hypolipidemic effects. It shows selective cytotoxic effects towards cancer cells. Ankaflavin has potential therapeutic applications in treating inflammatory diseases and cancer. Further in vivo studies are ongoing to fully characterize its therapeutic potential.
Enzyme Assay
Ankaflavin PPARγ binding assays involve measuring agonist activity at PPARγ. PPARγ activation is assessed using reporter gene assays or coactivator recruitment assays in cell-free systems. The compound's EC50 for PPARγ activation is determined through dose-response curves. Anti-inflammatory activity is assessed by measuring inhibition of pro-inflammatory cytokine production (e.g., TNF-α, IL-6) in cell-free systems. Anti-cancer activity is evaluated by assessing inhibition of cancer cell proliferation or induction of apoptosis. Assays are performed in appropriate buffer systems with positive controls such as known PPARγ agonists (e.g., rosiglitazone).

Tested Concentrations: 25 µg/mL
Incubation Duration: 48 hrs (hours)
Experimental Results: Hoechst staining shows significant chromatin condensation (fluorescent spots).
Ankaflavin cell-based assays are conducted in cancer cell lines and normal cells. Cells are cultured in appropriate media at 37°C with 5% CO2 and treated with Ankaflavin at varying concentrations (0-50 µg/mL, 48 h). Cell viability is assessed by MTT or CCK-8 assays. Apoptosis is evaluated by Annexin V/PI staining and caspase activity assays. PPARγ activation is assessed by measuring target gene expression. Inflammatory markers are measured by ELISA. Selectivity is confirmed by comparing effects on cancer cells versus normal cells. Experiments are performed in triplicate with appropriate positive and negative controls.
Animal Protocol
Animal/Disease Models: Wistar rats (4 weeks old), treated with methylglyoxal (MG) (600 mg/kg; oral) for 4 weeks to induce diabetes [2]
Doses: 10 mg/kg
Route of Administration: Oral administration 28-day
Experimental Results: PPARγ agonist activity exerted. Effectively reduces AGE (advanced glycation end products) levels in serum, liver and pancreas of MG-induced rats.
Ankaflavin in vivo studies are conducted in rodent models of inflammation, cancer, diabetes, and atherosclerosis. Animals are treated with Ankaflavin via oral administration (e.g., 10 mg/kg; p.o.; daily for 28 days). Disease progression is monitored by appropriate endpoints. For anti-diabetic studies, blood glucose and insulin levels are measured. For anti-inflammatory studies, cytokine levels are measured. For anti-cancer studies, tumor growth is monitored. For anti-atherosclerotic studies, lipid profiles and atherosclerotic plaque formation are assessed. Animals are monitored for clinical signs. Tissues and blood samples are collected for histopathological and biomarker analysis.

Its anti-inflammatory, anti-cancer, anti-atherosclerotic, and hypolipidemic effects have been demonstrated with acceptable safety profiles. No significant adverse effects have been reported in the available literature at research-use concentrations. The compound is intended for research use only. Standard safety precautions should be followed when handling. Comprehensive toxicological evaluation would be required for therapeutic development.
