Design, synthesis and biological evaluation of the positional isomers of the galactose conjugates able to target hepatocellular carcinoma cells via ASGPR-mediated cellular uptake and cytotoxicity. Eur J Med Chem 2024; 264:115988. [PMID: 38039790 DOI: 10.1016/j.ejmech.2023.115988] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/23/2023] [Revised: 11/19/2023] [Accepted: 11/20/2023] [Indexed: 12/03/2023]
Abstract
Galactose as a recognizing motif for asialoglycoprotein receptor (ASGPR) is a widely accepted vector to deliver cytotoxic agents in the therapy of hepatocellular carcinoma (HCC), however, the individual hydroxyl group of galactose (Gal) contributed to recognizing ASGPR is obscure and remains largely unanswered in the design of glycoconjugates. Herein, we designed and synthesized five positional isomers of Gal-anthocyanin Cy5.0 conjugates and three Gal-doxorubicin (Dox) isomers, respectively. The fluorescence intensity of Gal-Cy5.0 conjugates accumulated in cancer cells hinted the optimal modification sites of positions C2 and C6. Comparing to the cytotoxicity of other conjugates, C2-Gal-Dox (11) was the most potent. Moreover, Gal-Dox conjugates significantly the toxicity of Dox. A progressively lower internalization capacity and siRNA technology implied the cellular uptake and cytotoxicity directly related to the ASGPR expression level. Accordingly, position C2 of galactose may be the best substitution site via ASGPR mediation in the design of anti-HCC glycoconjugates.

Li M, Ye W, Fu K, Zhou C, Shi Y, Huang W, Chen W, Hu J, Jiang Z, Zhou W. Oligosaccharide-camptothecin conjugates as potential antineoplastic drugs: Design, synthesis and biological evaluation. Eur J Med Chem 2020; 202:112509. [PMID: 32668379 DOI: 10.1016/j.ejmech.2020.112509] [Citation(s) in RCA: 12] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/15/2020] [Revised: 05/20/2020] [Accepted: 05/23/2020] [Indexed: 10/24/2022]
Abstract
Thirty novel 20 (S)-O-linked camptothecin (CPT) glycoconjugates were synthesized. They showed more potent in vitro cytotoxicities over irinotecan, but very weak direct topoisomerase I (Topo I) inhibition was observed at 100.0 μM. Oligosaccharide types, length of a PEG linker and acetyl groups exerted obvious effects on cytotoxicity, selectivity, water solubility and stability of the newly synthesized CPT glycoconjugates. Construct 40, with a bleomycin (BLM) disaccharide linked to diethylene glycol in the introduced ester moiety, demonstrated a superior antitumor activity and a distinct selectivity compared to CPT. No toxicity was detectable in animal acute toxicity intravenously (160 mg/kg). Collectively, attachment of oligosaccharides with tumor targeting to 20 (S)-OH of CPT could offer a solution to the daunting problems posed by current Topo I poisons.

Abstract
The development of glycobiology relies on the sources of particular oligosaccharides in their purest forms. As the isolation of the oligosaccharide structures from natural sources is not a reliable option for providing samples with homogeneity, chemical means become pertinent. The growing demand for diverse oligosaccharide structures has prompted the advancement of chemical strategies to stitch sugar molecules with precise stereo- and regioselectivity through the formation of glycosidic bonds. This Review will focus on the key developments towards chemical O-glycosylations in the current century. Synthesis of novel glycosyl donors and acceptors and their unique activation for successful glycosylation are discussed. This Review concludes with a summary of recent developments and comments on future prospects.
