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

Andreana, Peter R.,Hossain, Farzana,Nishat, Sharmeen

, (2022/02/21)

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.

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.

Isosyringinoside (1) and 3-(O-β-D-glucopyranosyl)-α-(O-β-D-glucopyranosyl)-4-hydroxy phenylethanol (2), the natural bioactive compounds contained unique structures, were first totally synthesized using easily available materials in short convenient routes with overall yields of 20.2% and 27.0%, respectively. 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.

Scalable syntheses of piceatannol-3'-O-β-D-glucopyranoside and the 4'-methoxy congener thereof were achieved. This route features an early implemented Fischer-like glycosylation reaction, a regioselective iodination of phenolic glycoside under strongly acidic conditions, a highly telescoped route to access the styrene derivative, and a key Mizoroki.Heck reaction to render the desired coupled products in high overall yield.

A gulose moiety contributes to the belomycin (BLM) disaccharide selective targeting to lung cancer cells

Eight mono- or disaccharide analogues derived from BLM disaccharide, along with the corresponding carbohydate-dye conjugates have been designed and synthesized in this study, aiming at exploring the effect of a gulose residue on the cellular binding/uptake of BLM disaccharide and it possible uptake mechanism. Our evidence is presented indicating that, for the cellular binding/uptake of BLM disaccharide, a gulose residue is an essential subunit but unrelated to its chemical nature. Interestingly, D-gulose-dye conjugate is able to selectively target A549 cancer cells, but L-gulose-dye conjugate fails. Further uptake mechanism studies demonstrate D-gulose-dye derivatives similar to BLM disaccharide-dye ones behave in a temperature- and ATP-dependent manner, and are partly directed by the GLUT1 receptor. Moreover, D-gulose modifying gemcitabine 53a exhibits more potent antitumor activity compared to derivatives 53b-c in which gemcitabine is decorated with other monosaccharides. Taken together, the monosacharide D-gulose conjugate offers a new strategy for solving cytotoxic drugs via the increased tumor targeting in the therapy of lung cancer.

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

Chen, Zhenyu,Lin, Yan,Liu, Zhongbing,Luo, Zhongling,Lyu, Jiayao,Wang, Jianxin,Wei, Jun,Zhong, Zhirong

, p. 5016 - 5029 (2021/08/17)

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

Boltje, Thomas J.,Eerden, Nienke,Lefeber, Dirk J.,Merx, Jona,Noga, Marek J.,Pijnenborg, Johan F. A.,Rossing, Emiel,Titulaer, Willem H. C.,Veizaj, Raisa,White, Paul B.

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.

An alternative approach for the synthesis of sulfoquinovosyldiacylglycerol

Domey, Hendrik,Fischer, Judith,Rohn, Sascha,Sitz, Tobias

, (2021/07/28)

Sulfoquinovosyldiacylglycerol (SQDG) is a glycolipid ubiquitously found in photosyn-thetically active organisms. It has attracted much attention in recent years due to its biological ac-tivities. Similarly, the increasing demand for vegan and functional foods has led to a growing interest in micronutrients such as sulfolipids and their physiological influence on human health. To study this influence, reference materials are needed for developing new analytical methods and providing enough material for model studies on the biological activity. However, the availability of these materials is limited by the difficulty to isolate and purify sulfolipids from natural sources and the unavailability of chemical standards on the market. Consequently, an alternative synthetic route for the comprehensive preparation of sulfolipids was established. Here, the synthesis of a sulfolipid with two identical saturated fatty acids is described exemplarily. The method opens possibilities for the preparation of a diverse range of interesting derivatives with different saturated and unsatu-rated fatty acids.
