When compared to medical procedures and radiotherapy, chemotherapy has a distinct advantage in the treatment of malignant growth. Despite the production of medications with various systems for various cancers, patients experience severe side effects due to the unintended dispersion of free medications in common organs. For instance, the chemotherapy drug doxorubicin (DOX) is used to treat a wide range of cancers, including hepatic disease, breast disease, ovarian cancer, cellular breakdown in the lungs and delicate tissue sarcoma [1,2]. However, DOX's significant defects, such as its unfortunate objective person, low dissolvability, inadequate blood flow, heart harm and so on, significantly hinder its antitumor use. However, specific chemotherapeutic strategies that not only reduce medication dispersion in common organs but also increase medication gathering at growth sites are urgently required [3]. Through improved penetrability and maintenance (EPR) effects, the nano-sized vehicles can gather at growth locations; Second, these nanocarriers are able to detect cancer cells after being altered by specific ligands through unambiguous ligand-receptor cooperation. This provides a fantastic opportunity to overcome the inherent limitations of conventional disease treatments. Glycopolypeptide has recently received a lot of attention in clinical materials due to its unique subatomic structure and similar design to that of regular glycoproteins. Oligosaccharides typically appeared as sign particles near the end of glycoproteins. In addition, the presence of oligosaccharides prevents proteases from directly reaching the polypeptide, thereby reducing glycopolypeptide degradation and improving the materials' strength [4]. Even more so, some monosaccharides and polysaccharides, like -lactose (Lac), sialic acid (SA) and hyaluronic acid (HA), have shown the ability to target cancer cells. As a result, glycopolypeptide might be an excellent option for specific chemotherapy.


In order to function as a transporter, the glycopolypeptide could selfcollect into micelles of nanometer size through hydrophobic cooperation. Free DOX was chosen to serve as a model drug and it was then stacked into the center of GPM in close cooperation with the phenylalanine block [5] [solid -] In comparison to free DOX, the DOX-stacked GPM (i.e., GPM/DOX) displayed unparalleled properties: 1) The EPR impact of GPM/DOX could accumulate at the growth locations based on the appropriate size; 2) The medication stacking content (DLC) of GPM was clearly enhanced by the - stacking impact; (3) A 500 MHz Avance III HD atomic attractive reverberation spectrometer and a fourier change infrared spectrometer confirmed that the compound designs of these polymers could effectively target hepatic cells through particular recognition of Lac and ASGP-R. The liver fluorescence of the mice in the free DOX group was higher than that of the GPM/DOX group, indicating that the liver processed free DOX more rapidly. Similar results were observed in the hearts and kidneys of mice treated with free DOX, indicating a stronger poisoning of these two organs. However, the GPM/ DOX group had lower fluorescence power in the heart or kidney. Given that the mice injected with the GPM/DOX micelle displayed significantly more grounded DOX fluorescence force at growth sites than the free DOX group, it was warranted.

Histopathology and immunohistochemistry (IHC) examinations of mouse cancer tissues confirmed the antitumor effects of GPM/DOX. Hematoxylineosin (H&E) staining was used to prepare the areas of cancer tissue. Figure 4C (H&E) shows that the cancer cells in the benchmark group developed successfully, whereas the growth cells in the free DOX and GPM/ DOX groups began to die off. In addition, the growth corruption regions were the largest of all groups, approximately 1.2 times larger than the free DOX group. The growth restraint rates overall and the information for the cancer corruption regions remained constant. The capacity of cancer cells to expand was examined using a multiplying cell atomic antigen (PCNA) stain. Histopathology further concentrated the GPM/DOX security in vivo. As shown in Figure S4, the free DOX and GPM/DOX bunches showed some obsessive changes in H&E in the obsessive areas of the primary organs. The most important changes are as follows: I) aggravation and destruction of myocardial structure; (ii) The renal case depression diminished or disappeared. The fact that mice in the free DOX group had higher levels of damage to their hearts or kidneys than those in the GPM/DOX group further demonstrated that GPM/DOX was more secure than free DOX.


A micelle based on glycopolypeptide was prepared for designated hepatic risk chemotherapy. The GPM/DOX could lessen drug dispersion in nontargeted tissues and increase drug gathering in growths. Particularly, the medication concentration in the heart of the GPM/DOX groups was only one third that of the free DOX group, significantly reducing the cardiotoxicity of DOX, which unquestionably demonstrated a strong antitumor effect and high safety in vivo. GPM/DOX's straightforward interaction and excellent execution make clinical application possible.
