Abstract
Glycorandomization is a natural product derivatization strategy in which different sugar moieties are linked to the aglycone part of the naturally existing glycosides to create glycorandomized libraries. Sugars attached to the natural products are responsible for affecting their solubility, mechanism of action, target recognition, and toxicity and thus, by changing the sugar part, these properties could be modified. Glycorandomization can be done via two approaches (i) a synthetic approach known as neoglycorandomization, and (ii) chemoenzymatic approach including in-vitro and in-vivo glycorandomization. Glycorandomization can be a promising technology for the drug discovery that has proved its potential to improve pharmacokinetic (solubility) and pharmacodynamic profile (mechanism of action, toxicity, and target recognition) of the parent compounds. The substrate flexibility of glycosyltransferases and other enzymes towards sugars and/or aglycone substrates has made this technique versatile. Further, the enzymes can be altered by genetic engineering to generate glycorandomized libraries of diverse natural product scaffolds. This technique has the potential to produce new compounds that can be helpful to the mankind by treating the threatening disease states. This review covers the different strategies for glycorandomization as a tool in drug discovery and development. The fundamentals of glycorandomization, different types, and further development of differentially glycorandomized libraries of natural products and small molecule based drugs have been discussed.

Abstract
Amphiphilicity is one of the desirable features in the process of drug development which improves the biological as well as the pharmacokinetics profile of bioactive molecule. Carbohydrate moieties present in anti-cancer natural products and synthetic molecules influence the amphiphilicity and hence their bioactivity. This review focuses on natural and synthetic amphiphilic anti-cancer glycoconjugates. Different classes of molecules with varying degree of amphiphilicity are covered with discussions on their structure-activity relationship and mechanism of action.

Abstract
Glycan arrays have become a technique of choice to screen glycan-protein interactions in a high-throughput manner with high sensitivity and low sample consumption. Here, the synthesis of a new multifunctional fluorescent linker for glycan labeling via aminoxy ligation and immobilization is described; the linker features a fluorescent naphthalene group suitable for highly sensitive high-performance liquid chromatography-based purification and an azido- or amino-modified pentanoyl moiety for the immobilization onto solid supports. Several glycoconjugates displaying small sugar epitopes via chemical or chemoenzymatic synthesis were covalently attached onto a microarray support and tested with lectins of known carbohydrate binding specificity. The glycan library was extended using glycosyltransferases (e.g. galactosyl-, sialyl- and fucosyltransferases); the resulting neoglycoconjugates, which are easily detected by mass spectrometry, mimic antennal elements of N- and O-glycans, including ABH blood group epitopes and sialylated structures. Furthermore, an example natural plant N-glycan containing core α1,3-fucose and β1,2-xylose was also successfully conjugated to the fluorescent linker, immobilized and probed with lectins as well as antihorseradish peroxidase. These experiments validate our linker as being a potentially valuable tool to study glycozyme and lectin specificities, sensitive enough to allow purification of natural glycans.

Abstract
This review covers the literature published in 2013 for marine natural products (MNPs), with 982 citations (644 for the period January to December 2013) referring to compounds isolated from marine microorganisms and phytoplankton, green, brown and red algae, sponges, cnidarians, bryozoans, molluscs, tunicates, echinoderms, mangroves and other intertidal plants and microorganisms. The emphasis is on new compounds (1163 for 2013), together with the relevant biological activities, source organisms and country of origin. Reviews, biosynthetic studies, first syntheses, and syntheses that lead to the revision of structures or stereochemistries, have been included.

Abstract
![]()
A facile
route to perillyl alcohol (POH) differential glycosylation
and the corresponding synthesis of a set of 34 POH glycosides is reported.
Subsequent in vitro studies revealed a sugar dependent antiproliferative
activity and the inhibition of S6 ribosomal protein phosphorylation
as a putative mechanism of representative POH glycosides. The most
active glycoside from this cumulative study (4′-azido-d-glucoside, PG9) represents one of the most cytotoxic
POH analogues reported to date.

Abstract
Neoglycosylations are increasingly being employed in the synthesis of natural products, drug candidates, glycopeptide mimics, oligosaccharide analogues, and other applications, but the efficiency of these reactions is usually limited by slow reaction times. Here, we show that aniline derivatives such as 2-amino-5-methoxybenzoic acid enhance the rate of acid-catalyzed neoglycosylation for a range of sugar substrates up to a factor of 32 relative to the uncatalyzed reaction.

Abstract
A set of 37 doxycycline neoglycosides were prepared, mediated via a C-9 alkoxyamino-glycyl-based spacer reminiscent of that of tigecycline. Subsequent in vitro antibacterial assays against representative drug-resistant Gram negative and Gram positive strains revealed a sugar-dependent activity profile and one doxycycline neoglycoside, the 2'-amino-α-D-glucoside conjugate, to rival that of the parent pharmacophore. In contrast, the representative tetracycline-susceptible strain E. coli 25922 was found to be relatively responsive to a range of doxycycline neoglycosides. This study also extends the use of aminosugars in the context of neoglycosylation via a simple two-step strategy anticipated to be broadly applicable for neoglycorandomization.
