Abstract
Multivalent glycosidase inhibitors based on 1-deoxynojirimycin derivatives against α-glucosidases have been rapidly developed. Nonetheless, the mechanism based on self-assembled multivalent glucosidase inhibitors in living systems needs to be further studied. It remains to be determined whether the self-assembly possesses sufficient stability to endure transit through the small intestine and subsequently bind to the glycosidases located therein. In this paper, two amphiphilic compounds, 1-deoxynojirimycin and α-peptoid conjugates (LP-4DNJ-3C and LP-4DNJ-6C), were designed. Their self-assembling behaviors, multivalent α-glucosidase inhibition effect, and fluorescence imaging on living organs were studied. LP-4DNJ-6C exhibited better multivalent α-glucosidase inhibition activities in vitro. Moreover, the self-assembly of LP-4DNJ-6C could effectively form a complex with Nile red. The complex showed fluorescence quenching effect upon binding with α-glucosidases and exhibited potent fluorescence imaging in the small intestine. This result suggests that a multivalent hypoglycemic effect achieved through self-assembly in the intestine is a viable approach, enabling the rational design of multivalent hypoglycemic drugs.

Abstract
Synthetic glycoconjugates as chemical probes have been widely developed for the detection of glycosidase enzymes. However, the binding interactions between iminosugar derivatives and glycosidases were limited, especially for the binding interactions between multivalent glycosidase inhibitors and α-glycosidases. In this paper, three naphthalimide-DNJ conjugates were synthesized. Furthermore, the binding interactions and glycosidase inhibition effects of them were investigated. It was found that the strong binding interactions of multivalent glycosidase inhibitors with enzymes were related to the efficient inhibitory activity against glycosidase. Moreover, the lengths of the chain between DNJ moieties and the triazole ring for the naphthalimide-DNJ conjugates influenced the self-assembly properties, binding interactions and glycosidase inhibition activities with multisource glycosidases. Compound 13 with six carbons between the DNJ moiety and triazole ring showed the stronger binding interactions and better glycosidase inhibition activities against α-mannosidase (jack bean) and α-glucosidase (aspergillus niger). In addition, compound 13 showed an effective PBG inhibition effect in mice with 51.18 % decrease in blood glucose at 30 min. This result opens a way for detection of multivalent glycosidase inhibition effect by a fluorescent sensing method.

Abstract
5-C-Alkyl-DNJ and 5-C-alkyl-l-ido-DNJ derivatives have been designed and synthesized efficiently from an l-sorbose-derived cyclic nitrone. The DNJ and l-ido-DNJ derivatives with C-5 alkyl chains ranging from methyl to dodecyl were assayed against various glycosidases to study the effect of chain length on enzyme inhibition. Glycosidase inhibition study of DNJ derivatives showed potent and selective inhibitions of α-glucosidase; DNJ derivatives with methyl, pentyl to octyl, undecyl and dodecyl as C-5 branched chains showed significantly improved rat intestinal maltase inhibition. In contrast, most 5-C-alkyl-l-ido-DNJ derivatives were weak or moderate inhibitors of the enzymes tested, with only three compounds found to be potent α-glucosidase inhibitors. Docking studies showed different interaction modes of 5-C-ethyl-DNJ and 5-C-octyl-DNJ with ntMGAM and also different binding modes of 5-C-alkyl-DNJ and 5-C-alkyl-l-ido-DNJ derivatives; the importance of the degree of accommodation of the C-5 substituent in the hydrophobic groove and pocket may account for the variation of glycosidase inhibition in the two series of derivatives. The results reported herein are helpful in the design and development of α-glucosidase inhibitors; this may lead to novel agents for the treatment of viral infection and type II diabetes.

Abstract
Although multivalent glycosidase inhibitors have shown enhanced glycosidase inhibition activities, further applications and research directions need to be developed in the future. In this paper, two positional isomeric perylene bisimide derivatives (PBI-4DNJ-1 and PBI-4DNJ-2) with 1-deoxynojirimycin conjugated were synthesized. Furthermore, PBI-4DNJ-1 and PBI-4DNJ-2 showed positional isomeric effects on the optical properties, self-assembly behaviors, glycosidase inhibition activities, and hypoglycemic effects. Importantly, PBI-4DNJ-1 exhibited potent hypoglycemic effects in mice with 41.33 ± 2.84 and 37.45 ± 3.94% decreases in blood glucose at 15 and 30 min, respectively. The molecular docking results showed that the active fragment of PBI-4DNJ-1 has the highest binding energy (9.649 kcal/mol) and the highest total hydrogen bond energy (62.83 kJ/mol), which were related to the positional isomeric effect on the hypoglycemic effect in mice. This work introduced a new means to develop antihyperglycemic agents in the field of multivalent glycomimetics.

Abstract
Monoclonal antibodies have been developed as anticancer agents to block immune checkpoint pathways associated with programmed cell death 1 (PD-1) and its ligand PD-L1. However, the high cost of antibodies has encouraged researchers to develop other inhibitor types. Here, biphenyl compounds were conjugated with poly(ethylene glycol) (PEG) to enhance the activity of small molecular inhibitors. Immunoassay results revealed the decrease in the inhibition activity following conjugation with linear PEG, suggesting that the PEG moiety reduced the interaction between the biphenyl structure and PD-L1. However, the inhibitory effect on PD-1/PD-L1 interaction was further enhanced by using branched PEG conjugates. The increase in the number of conjugated biphenyl compounds resulted in increased inhibitory activity. The highest IC50 value was 0.33 μM, which was about 5 times higher than that observed for a non-conjugated monovalent compound. The inhibitory activity was more than 20 times the activity reported for the starting compound. Considering the increase in the inhibition activity, this multivalent strategy can be useful in the design of new immune checkpoint inhibitors.

Abstract
Glycosidases are ubiquitous enzymes involved in a diversity of key biological processes such as energy uptake or cell wall degradation. The design of specific glycosidase inhibitors has been therefore the subject of intense research efforts in academia and pharmaceutical industry. However, until recently, the study of the impact of multivalency on glycosidase inhibition was almost completely neglected. The following account will review our ten year journey on the design of multivalent glycomimetics within our research group, from the discovery of the first strong multivalent effect in glycosidase inhibition to the high-resolution crystal structures of Jack bean α-mannosidase in complex with the multimeric inhibitor displaying the largest binding enhancements reported so far.
