| Abstract |
Annonaceous acetogenins (ACGs) have shown superior antitumor activity against a variety of cancer cell lines, but their clinical application has been limited by their poor solubility. In this study, ACGs-nanosuspensions (NSps) were successfully prepared by a precipitation ultrasonic method using monomethoxypoly (ethylene glycol)2000-poly (ε-caprolactone)2000 (mPEG2000-PCL2000) as a stabilizer. The resultant ACGs-NSps had a mean particle size of 123.2 nm, a zeta potential of -20.17 mV, and a high drug payload of 73.68%. ACGs-NSps were quite stable in various physiological solutions, and they exhibited sustained drug release. Compared to free drug, ACGs-NSps exhibited stronger cytotoxicity against 4T1, MCF-7, and HeLa cells. An in vivo real-time biodistribution investigation after labeling with 1,1'-dioctadecyltetramethyl indotricarbocyanine iodide, a noninvasive near-infrared fluorescence probe, demonstrated that ACGs-NSps could effectively accumulate in tumor. An in vivo antitumor activity study in 4T1 tumor-bearing mice revealed that ACGs-NSps achieved much better therapeutic efficacy than the traditional dosage form (oil solution) even at 1/10 of the dose (74.83% vs 45.53%, P<0.05), demonstrating that NSp was a good dosage form for ACGs to treat cancer. |

Attention Score in Context
This research output has an Altmetric Attention Score of 1. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 19 July 2016.
All research outputs
#17,286,379
of 25,374,647 outputs
Outputs from International Journal of Nanomedicine
#2,469
of 4,123 outputs
Outputs of similar age
#237,606
of 367,269 outputs
Outputs of similar age from International Journal of Nanomedicine
#101
of 121 outputs
Altmetric has tracked 25,374,647 research outputs across all sources so far. This one is in the 21st percentile – i.e., 21% of other outputs scored the same or lower than it.
So far Altmetric has tracked 4,123 research outputs from this source. They receive a mean Attention Score of 4.7. This one is in the 28th percentile – i.e., 28% of its peers scored the same or lower than it.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 367,269 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 27th percentile – i.e., 27% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 121 others from the same source and published within six weeks on either side of this one. This one is in the 7th percentile – i.e., 7% of its contemporaries scored the same or lower than it.
