Synthesis of malformin-A1, C, a glycan, and an aglycon analog: Potential scaffolds for targeted cancer therapy

Improvement in therapeutic efficacy while reducing chemotherapeutic side effects remains a vital objective in synthetic design for cancer treatment. In keeping with the ethos of therapeutic development and inspired by the Warburg effect for augmenting biological activities of the malformin family of cyclic-peptide natural products, specifically anti-tumor activity, a β-glucoside of malformin C has been designed and synthesized utilizing precise glycosylation and solution phase peptide synthesis. We optimized several glycosylation procedures utilizing different donors and acceptors. The overarching goal of this study was to ensure a targeted delivery of a glyco-malformin C analog through the coupling of D-glucose moiety; selective transport via glucose transporters (GLUTs) into tumor cells, followed by hydrolysis in the tumor microenvironment releasing the active malformin C a glycon analog. Furthermore, total synthesis of malformin C was carried out with overall improved strategies avoiding unwanted side reactions thus increasing easier purification. We also report on an improved solid phase peptide synthesis protocol for malformin A1.

Synthesis of Glycosyl Fluorides by Photochemical Fluorination with Sulfur(VI) Hexafluoride

This study describes a new convenient method for the photocatalytic generation of glycosyl fluorides using sulfur(VI) hexafluoride as an inexpensive and safe fluorinating agent and 4,4′-dimethoxybenzophenone as a readily available organic photocatalyst. This mild method was employed to generate 16 different glycosyl fluorides, including the substrates with acid and base labile functionalities, in yields of 43%-97%, and it was applied in continuous flow to accomplish fluorination on an 7.7 g scale and 93% yield.

Rh2(II)-Catalyzed intermolecular N-Aryl aziridination of olefins using nonactivated N atom precursors

The development of the first intermolecular Rh2(II)-catalyzed aziridination of olefins using anilines as nonactivated N atom precursors and an iodine(III) reagent as the stoichiometric oxidant is reported. This reaction requires the transfer of an N-aryl nitrene fragment from the iminoiodinane intermediate to a Rh2(II) carboxylate catalyst; in the absence of a catalyst only diaryldiazene formation was observed. This N-aryl aziridination is general and can be successfully realized by using as little as 1 equiv of the olefin. Di-, tri-, and tetrasubstituted cyclic or acylic olefins can be employed as substrates, and a range of aniline and heteroarylamine N atom precursors are tolerated. The Rh2(II)-catalyzed N atom transfer to the olefin is stereospecific as well as chemo- and diastereoselective to produce the N-aryl aziridine as the only amination product. Because the chemistry of nonactivated N-aryl aziridines is underexplored, the reactivity of N-aryl aziridines was explored toward a range of nucleophiles to stereoselectively access privileged 1,2-stereodiads unavailable from epoxides, and removal of the N-2,4-dinitrophenyl group was demonstrated to show that functionalized primary amines can be constructed.

Total synthesis of three natural phenethyl glycosides

Phenethyl glycosides having phenolic or methoxy functions at benzene rings are substances widely occurring in nature. This kind of compounds has been shown to have anti-oxidant, anti-inflammatory, and anticancer activities. However, some of them are not naturally abundant, thus the synthesis of such molecules is desirable. In this paper, natural phenethyl glycosides 3 and 4 were first totally synthesized from easily available materials with overall yields of 50.5% and 40.1%, respectively. And a new synthetic route to obtain natural phenethyl glycoside 2 in 46.2% yield was also described.

First total syntheses of two natural glycosides

An efficient total synthesis of 1 was developed in six steps, which contained two key steps of highly regioselective glycosylation without any selective protection steps. The seven-step synthesis of 2 involved two steps of regioselective glycosylations using BF3–O(C2H5)2 and TMSOTf as catalysts, respectively.

Preparation and formulation optimization of methotrexate-loaded human serum albumin nanoparticles modified by mannose

Background: Methotrexate (MTX) is the representative drug among the dis-ease-modifying anti-rheumatic drugs. However, the conventional treatment with MTX showed many limitations and side effects. Objective: To strengthen the targeting ability and circulation time of MTX in the treatment of rheumatoid arthritis, the present study focused on developing a novel drug delivery system of methotrexate-loaded human serum albumin nanoparticles (MTX-NPs) modified by mannose, which are referred to as MTX-M-NPs. Methods: Firstly, mannose-derived carboxylic acid was synthesized and further modified on the surface of MTX-NPs to prepare MTX-M-NPs. The formulation of nanoparticles was optimized by the method of central composite design (CCD), with the drug lipid ra-tio, oil-aqueous ratio, and cholesterol or lecithin weight as the independent variables. The average particle size and encapsulation efficiency were the response variables. The response of different formulations was calculated, and the response surface diagram, con-tour diagram, and mathematical equation were used to relate the dependent and independent variables to predict the optimal formula ratio. The uptake of MTX-M-NPs by neu-trophils was studied through confocal laser detection. Further, MTX-M-NPs were subject-ed to assessment of the pharmacokinetics profile after intravenous injection with Sprague-Dawley rats. Results: This targeting drug delivery system was successfully developed. Results from Nuclear Magnetic Resonance and Fourier Transform Infrared Spectroscopy analysis can verify the successful preparation of this drug delivery system. Based on the optimized for-mula, MTX-M-NPs were prepared with a particle size of 188.17 ± 1.71 nm and an encapsulation rate of 95.55 ± 0.33%. MTX-M-NPs displayed significantly higher cellular uptake than MTX-NPs. The pharmacokinetic results showed that MTX-M-NPs could pro-long the in vivo circulation time of MTX. Conclusion: This targeting drug delivery system laid a promising foundation for the treatment of RA.

Fluorinated rhamnosides inhibit cellular fucosylation

The sugar fucose is expressed on mammalian cell membranes as part of glycoconjugates and mediates essential physiological processes. The aberrant expression of fucosylated glycans has been linked to pathologies such as cancer, inflammation, infection, and genetic disorders. Tools to modulate fucose expression on living cells are needed to elucidate the biological role of fucose sugars and the development of potential therapeutics. Herein, we report a class of fucosylation inhibitors directly targeting de novo GDP-fucose biosynthesis via competitive GMDS inhibition. We demonstrate that cell permeable fluorinated rhamnose 1-phosphate derivatives (Fucotrim I & II) are metabolic prodrugs that are metabolized to their respective GDP-mannose derivatives and efficiently inhibit cellular fucosylation.
