Abstract
Anacardic acid (AA) is a natural active ingredient that accounts for 65% of the liquid extract from the shell of the cashew nut. Due to the stronger cytotoxic activity of hydrogenated AA (HAA) against NTERA-2 cancer stem cells (CSCs) than AA itself, HAA was co-conjugated with CD133 monoclonal antibody (mAb^CD133) into nanoliposomal particles (AMC). This nanoliposomal complex is expected to improved HAA activities against CSCs based on the targeting capacity of mAb^CD133 toward CD133, a typical CSCs’ surface marker. AMC was manufactured with a mean size of 100.9 nm, a zeta potential of −40.7 mV, and a PDI of 0.283. We report a 100% encapsulation efficiency of HAA into liposomes and a 90.7% conjugation efficiency with mAb^CD133. The penetration of AMC into NTERA-2 CSCs after 2 h was 83.7%. The AMC complex inhibited NTERA-2 growth with an IC50 (inhibition concentration at 50%) value of 75.83 ± 6.70 µM, showing the targeting ability and lower toxicity (IC50 > 100 µM) on healthy cells. The AMC nanoparticles also demonstrated significant potential apoptotic induction by activating caspase 3 activity by up to 2.57 and 2.06 folds compared to that of the negative control at 20 and 4 µM, respectively. This induction was significant improvement in comparison with that of unconjugated HAA ( P < .05). AMC presented a clear effect on the solid structure of NTERA-2 spheroids and significantly suppressed the proliferation of CSCs in the 3D tumorspheres with an IC50 = 64.25 ± 3.15 µM, compared to the free form with an IC50 = 82.22 ± 0.65 µM ( P < .05). Therefore, this nanoliposomal complex exhibits promising capacities as an effective material against NTERA-2 CSCs.

Abstract
Black pepper ( Piper nigrum L.) is widely grown in the Chu-se district of Gia Lai province in Vietnam. The pepper, used as a spice, also serves as a traditional medicine in many countries. Black pepper contains many different substances; the most active of these is piperine, which exerts anti-oxidant, anti-inflammatory, and anti-cancer effects. However, piperine is a poorly absorbed alkaloid, and high concentrations may be toxic. Therefore, its medicinal uses remain limited. Here, we extracted piperine from black peppers collected at Chu Se, created piperine and anti-CD133 monoclonal antibodies (mAb^CD133) containing nanoliposomal complexes (PMCs), and evaluated their inhibitory effects on cancer stem cells (CSCs) in vitro. The physical properties of PMCs showed an approximated diamater of 170 nm, a PDI of 0.23, zeta potential of −9.38 mV, and an encapsulated efficiency of 73.33 ± 9.09%. The PMCs significantly inhibited NTERA-2 cell growth (IC50 = 435.3 ± 4.3 µM), but were not toxic to healthy cells (IC50 >500 µM). The PMCs remarkably affected the CSC surface marker expressed level of which the CD44+/CD133+ population was only 2.12% compared with 21.72% for blank nanoliposomes. The NTERA-2 antiproliferative activities of PMCs might be associated with their G2 cell cycle phase arresting and caspase-3 inducible activities (up to 1.51 times) ( P < 0.05). The nanoliposomal complex also significantly inhibited the proliferation of NTERA-2 cells in three dimensional tumorspheroids with an IC50 = 245.82 ± 11.44 µM and reduced the size by up to 41.50 ± 4.31% ( P < 0.05). Thus, the PMCs proved their enhanced potential biomedical and pharmacological applications in targeted cancer therapies.
