Abstract
A concise asymmetric synthesis of clickable enantiomeric pyrrolidines was achieved using Crabbé-Ma allenation. The synthesized iminosugars were grafted by copper-free strain-promoted alkyne-azide cycloaddition onto phosphorus dendrimers. The hexavalent and dodecavalent pyrrolidines were evaluated as β-glucocerebrosidase inhibitors. The level of inhibition suggests that monofluorocyclooctatriazole group may contribute to the affinity for the protein leading to potent multivalent inhibitors. Docking studies were carried out to rationalize these results. Then, the iminosugars clusters were evaluated as pharmacological chaperones in Gaucher patients' fibroblasts. An increase in β-glucocerebrosidase activity was observed with hexavalent and dodecavalent pyrrolidines at concentrations as low as 1 µM and 0.1 µM, respectively. These iminosugar clusters constitute the first example of multivalent pyrrolidines acting as pharmacological chaperones against Gaucher disease.

Abstract
The first phosphorus dendrimers built on a cyclotriphosphazene core and decorated with six or twelve monofluorocyclooctyne units were prepared. A simple stirring allowed the grafting of N-hexyl deoxynojirimycin inhitopes onto their surface by copper-free strain promoted alkyne-azide cycloaddition click reaction. The synthesized iminosugars clusters were tested as multivalent inhibitors of the biologically relevant enzymes β-glucocerebrosidase and acid α-glucosidase, involved in Gaucher and Pompe lysosomal storage diseases, respectively. For both enzymes, all the multivalent compounds were more potent than the reference N-hexyl deoxynojirimycin. Remarkably, the final dodecavalent compound proved to be one of the best β-glucocerebrosidase inhibitors described to date. These cyclotriphosphazene-based deoxynojirimycin dendrimers were then evaluated as pharmacological chaperones against Gaucher disease. Not only did these multivalent constructs cross the cell membranes but they were also able to increase β-glucocerebrosidase activity in Gaucher cells. Notably, dodecavalent compound allowed a 1.4-fold enzyme activity enhancement at a concentration as low as 100 nM. These new monofluorocyclooctyne-presenting dendrimers may further find numerous applications in the synthesis of multivalent objects for biological and pharmacological purposes.

Abstract
A concise and asymmetric synthesis of the enantiomeric pyrrolidines 2 and ent-2 are herein reported. Both enantiomers were assessed as β-GCase inhibitors. While compound ent-2 acted as a poor competitive inhibitor, its enantiomer 2 proved to be a potent non-competitive inhibitor. Docking studies were carried out to substantiate their respective protein binding mode. Both pyrrolidines were also able to enhance lysosomal β-GCase residual activity in N370S homozygous Gaucher fibroblasts. Notably, the non-competitive inhibitor 2 displayed an enzyme activity enhancement comparable to that of reference compounds IFG and NN-DNJ. This work highlights the impact of inhibitors chirality on their protein binding mode and shows that, beyond competitive inhibitors, the study of non-competitive ones can lead to the identification of new relevant parmacological chaperones.

Abstract
Protein misfolding induced by missense mutations is the source of hundreds of conformational diseases. The cell quality control may eliminate nascent misfolded proteins, such as enzymes, and a pathological loss-of-function may result from their early degradation. Since the proof of concept in the 2000s, the bioinspired pharmacological chaperone therapy became a relevant low-molecular-weight compound strategy against conformational diseases. The first-generation pharmacological chaperones were competitive inhibitors of mutant enzymes. Counterintuitively, in binding to the active site, these inhibitors stabilize the proper folding of the mutated protein and partially rescue its cellular function. The main limitation of the first-generation pharmacological chaperones lies in the balance between enzyme activity enhancement and inhibition. Recent research efforts were directed towards the development of promising second-generation pharmacological chaperones. These non-inhibitory ligands, targeting previously unknown binding pockets, limit the risk of adverse enzymatic inhibition. Their pharmacophore identification is however challenging and likely requires a massive screening-based approach. This review focuses on second-generation chaperones designed to restore the cellular activity of misfolded enzymes. It intends to highlight, for a selected set of rare inherited metabolic disorders, the strategies implemented to identify and develop these pharmacologically relevant small organic molecules as potential drug candidates.

Abstract
Dysregulation of the ceramide transport protein CERT is associated to diseases such as cancer. In search for new CERT START domain ligands, N-dodecyl-deoxynojirimycin (N-dodecyl-DNJ) iminosugar was found to display, as a ceramide mimic, significant protein recognition. To reinforce the lipophilic interactions and strengthen this protein binding, a docking study was carried out in order to select the optimal position on which to introduce an additional O-alkyl chain on N-dodecyl-DNJ. Analysis of the calculated poses for three different regioisomers indicated an optimal calculated interaction pattern for N,O3-didodecyl-DNJ. The two most promising regioisomers were prepared by a divergent route and their binding to the CERT START domain was evaluated with fluorescence intensity (FLINT) binding assay. N,O3-didodecyl-DNJ was confirmed to be a new binder prototype with level of protein recognition in the FLINT assay comparable to the best known ligands from the alkylated HPA-12 series. This work opens promising perspectives for the development of new inhibitors of CERT-mediated ceramide trafficking.

Abstract
The enigmatical dichotomy between the two CERT/GPBP protein isoforms, their vast panel of biological implications and the scarcity of known antagonist series call for new ligand chemotypes identification. We report the design of iminosugar-based ceramide mimics for the development of new START domain ligands potentially targeting either protein isoforms. Strategic choice of (i) an iminoxylitol core structure and (ii) the positioning of two dodecyl residues led to an extent of protein binding comparable to that of the natural cargo lipid ceramide or the archetypical inhibitor HPA-12. Molecular docking study evidenced a possible mode of protein binding fully coherent with the one observed in crystalline co-structures of known ligands. The present study thus paves the way for cellular CERT inhibition studies en route to the development of pharmacological tools aiming at deciphering the respective function and therapeutic potential of the two CERT/GPBP protein isoforms.

Abstract
The synthesis of the thymidine 2-deoxypolyoxin C analogue 10 from a noncarbohydrate precursor was achieved in 10 steps and 9% yield starting from a chiral gamma,delta-epoxy-beta-hydroxy ester 11 readily available from cis-2-butene-1,4-diol. The main steps concern the stereo- and regioselective opening of the epoxide ring by an azide anion, the stereoselective introduction of the thymine base, and the transformation of the primary alcohol to the acid functionality of the final product. Two other approaches have also been investigated.
