title: Synergistic Chemotherapeutic Activity of Curcumin Bearing Methoxypolyethylene Glycol-g-Linoleic Acid Based Micelles on Breast Cancer Cells.
abstract: Although curcumin (Cur), has been poised to be an anticancer boon for quite some, its progress from bench to bed has been strained due to various pharmaceutical hurdles. Consequently curcumin has been entrapped in methoxy poly ethylene glycol and linoleic acid conjugated polymeric micelles (PMs) to not only tackle the routine issues but to also provide a synergetic effect against MCF-7 breast cancer cells. Optimized PMs of Cur had size 186.53 ± 12.10 nm with polydispersity index 0.143 ± 0.031 and zeta potential -30.1 ± 3.2 mV. Developed formulation (Mpeg-Cla-Cur PMs) was hemocompatible and had high cytotoxicity (IC50 55.80 ± 4.63 µ/mL) against MCF-7 cells in comparison to pure Cur suspension (IC50 75.05 ± 5.75 µg/mL). As postulated cell cycle arrest and apoptosis studies revealed synergetic effect of Mpeg-Cla-Cur PMs with higher cell population in G1 phase in addition to high apoptosis of MCF-7 cells as compared to pure Cur suspension and con- trol group. Pharmacokinetic studies also show PMs enhanced MRT and T1/2 of Cur indicating its longer retention time in body. Mpeg-Cla-Cur PMs might become as an excellent chemotherapeutic alternative candidate for treatment of breast cancer with higher commercial value.
