Abstract
Aldolase A (ALDOA) promotes hepatocellular carcinoma (HCC) growth and is a potential therapeutic target. A previous study found an α-D-glucan (α-D-(1,6)-Glcp-α-D-(1,4)-Glcp, 10.0:1.0), named HDPS-4II, that could specifically inhibit ALDOA but its activity was not high enough. In this study, the derivatives of α-D-glucan binding to ALDOA were optimized using molecular docking, and its sulfated modification demonstrated the highest affinity with ALDOA among sulfated, carboxylated, and aminated derivatives. Sulfated HDPS-4II and dextrans with different molecular weights (1000 Da, 3000 Da, and 4000 Da) were prepared. Using MST assay, 3-O-sulfated HDPS-4II (SHDPS-4II) and 1000 Da dextran (SDextran1) showed higher affinities to ALDOA with Kd of 1.83 μM and 85.04 μM, respectively. Furthermore, SHDPS-4II and SDextran1 markedly inhibited the proliferation of HCC cells both in vitro and in vivo by blocking ALDOA. These results demonstrate that sulfated modification of α-D-glucans could enhance their affinities with ALDOA and anti-HCC effects.

Abstract
Hepatocellular carcinoma (HCC) is a malignant tumor of the digestive system that poses a serious threat to human life and health. Chemotherapeutic drugs commonly used in the clinic have limited efficacy and heavy adverse effects. Therefore, it is imperative to find effective and safe alternatives, and natural polysaccharides (NPs) fit the bill. This paper summarizes in detail the anti-HCC activity of NPs in vitro, animal and clinical trials. Furthermore, the addition of NPs can reduce the deleterious effects of chemotherapeutic drugs such as immunotoxicity, bone marrow suppression, oxidative stress, etc. The potential mechanisms are related to induction of apoptosis and cell cycle arrest, block of angiogenesis, invasion and metastasis, stimulation of immune activity and targeting of MircoRNA. And on this basis, we further elucidate that the anti-HCC activity may be related to the monosaccharide composition, molecular weight (Mw), conformational features and structural modifications of NPs. In addition, due to its good physicochemical properties, it is widely used as a drug carrier in the delivery of chemotherapeutic drugs and small molecule components. This review provides a favorable theoretical basis for the application of the anti-HCC activity of NPs.

Abstract
Alfalfa polysaccharides (AP) receive wide attention in the field of medicine, because of their anti-inflammatory property. However, AP has high molecular weight and poor water solubility, resulting in low biological activity. We wanted to obtain highly bioactive alfalfa polysaccharides for further research. Herein, we successfully synthesized highly substituted sulfated alfalfa polysaccharides (SAP) via the chlorosulfonic acid (CSA)-pyridine (Pyr) method, which was optimized using response surface methodology (RSM). Under the best reaction conditions, that is, the reaction temperature, time, and ratio of CSA to Pyr being 55 °C, 2.25 h, and 1.5:1, respectively, the maximum degree of substitution of SAP can reach up to 0.724. Fourier transform infrared spectroscopy also confirmed the existence of sulfonic acid groups on SAP. Despite the increased average molecular weight of SAP, its water solubility is improved, which is beneficial for its biological activity. Further in vitro results showed that SAP exhibited better antioxidant activity and antibacterial ability than AP. Besides, the former can efficiently enhance the viability of oxidatively stressed intestinal epithelial cells compared with the latter. Furthermore, SAP has the potential to inhibit obesity. It is concluded that sulfation modification could improve the antioxidant, antibacterial, bovine intestinal epithelial cells’ proliferation-promoting, and the obesity inhibition abilities of AP. The improvement of AP biological activity may provide references for the utilization of plant extracts that have weaker biological activity.
