Description:
Context: It was found that flavonoids and frankincense exert anti-cancer
effect through their antioxidant and anti-inflammatory activities.
Aims: To evaluate the cytotoxic effect against MCF-7 cells of flavonoids
isolated from Physalis pubescens L., frankincense ethanol extract and the
combined therapy with epirubicin to reduce the resistance and the side
effects.
Methods: MTT assay against MCF-7 was carried out for rutin, quercitrin,
myricitrin and frankincense. The compound or extract with the best
anti-cancer effect was tested against WI-38 cells. 50% inhibitory
concentration (IC50) of the different treatments and the combined
therapy with epirubicin against MCF-7 was determined. Assessment the
effect on expression of ABCB1, TGF-?1 and ATG7 genes was done by
RT-qPCR.
Results: Isolation and identification of myricitrin from leaves of Physalis
pubescens L. was carried out for the first time. IC50 (µg/mL) regarding
MCF-7 cells was of epirubicin (0.8 ± 0.052), rutin (350.16 ± 1.241),
quercitrin (259.6 ± 1.45), myricitrin (114.0 ± 0.517), frankincense ethanol
extract (86.8 ± 0.91), combined epirubicin + myricitrin (EM) (0.37 ±
0.087), combined epirubicin + frankincense (EF) (0.50 ± 0.1732). The IC50
µg/mL regarding WI-38 cells was of epirubicin (1.26 ± 0.0057),
myricitrin (462.0 ± 1.062) and frankincense (299.5 ± 1.32). All assays were
done at 48 h time interval. Myricitrin and EM reduced ABCB1
expression and upregulated expression of TGF-?1 and ATG7 genes.
Frankincense and EF downregulated expression of ABCB1, TGF-?1 and
ATG7 genes.
Conclusions: Myricitrin and frankincense would be a promising adjuvant
therapy to improve epirubicin anticancer activity with minimal adverse
effect
