Abstract: Abemaciclib (Abm) is a CDK inhibitor that specifically targets the CDK4/6 cell cycle
pathway and has potential anticancer activity. Unfortunately, it has a low solubility and dissolution
rate.
Aim: The aim of this study is to enhance the solubility of ABM by loading it onto a chitosan (CS)
polymer.
Method: Polymer nanoparticle (NP) and Abm-CSNPs nanocomposites were prepared. Minitab 18
software was used to design 18 run samples to study the effects of CS, tripolyphosphate, and pH as
independent variables on the loading efficiency and particle size (dependent variable). The response
surface methodology (RSM) was also used to determine how the variables affected the response.
The graphical analysis used surface plots, main effects plots, contour plots, and interaction graphs.
The study includes F values, P values, variance inflation factors (VIFs), adjusted sums of square
(Adj SSs), adjusted mean squares (Adj MSs) and square error of the coefficient (SE Coef). The
carriers and loaded samples were also examined using the results of tests, including Fourier transform
infrared spectroscopy, X-ray diffraction, and scanning electron microscopy. Furthermore, the
release of Abm from Abm-CSNPs nanocomposite was studied in vitro.
Results: The results revealed an ability to produce particle sizes ranging from (168-192) nm and
loading efficiencies from (56.7-62.1).
Conclusion: Abm-CSNPs nanocomposite may be used as an alternative drug delivery system for
Abm to increase the release time of Abm to 1400 minutes.
