Engineered s-Triazine-Based Dendrimer-Honokiol Conjugates as Targeted MMP-2/9 Inhibitors for Halting Hepatocellular Carcinoma. ChemMedChem 2021; 16:3701-3719. [PMID: 34547831 DOI: 10.1002/cmdc.202100465] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/01/2021] [Revised: 09/20/2021] [Indexed: 12/17/2022]
Abstract
Despite the advances in developing MMP-2/9 inhibitors, off-target side effects and pharmacokinetics problems remain major challenges hindering their clinical success in cancer therapy. However, recent targeting strategies have clearly revitalized MMP research. Herein, we introduce new s-triazine-based dendrimers endowed with intrinsic MMP-2/9 inhibitory potential and tetherable to hepatocellular carcinoma-specific targeting ligands and anticancer agents via biodegradable linkages for targeted therapy. The designed dendrimeric platform was built with potential zinc-binding branching linkers (hydrazides) and termini (carboxylic acids and hydrazides) to confer potency against MMP-2/9. Preliminary cytotoxicity screening and MMP-2/9 inhibition assay of the free dendrimers revealed promising potency (MMP-9; IC50 =0.35-0.57 μM, MMP-2; IC50 =0.39-0.77 μM) within their safe doses (EC100 =94.15-42.75 μM). The hydrazide dendrimer was comparable to NNGH and superior to the carboxylic acid analogue. MTT assay showed that the free dendrimers were superior to the reference anticancer agent honokiol. Their anticancer potency was enhanced by HK conjugation, targeting ligands installation and PEGylation as exemplified by the hydrazide dendrimer conjugate (TPG3 -NH2 )-SuHK-FA-SuPEG (Huh-7; IC50 =5.54 μM, HepG-2; IC50 =10.07 μM) being 4 folds more active than HK, followed by the carboxylic acid conjugate (TPG3 -OH)-HK-LA-PEG (Huh-7; IC50 =14.97, HepG-2; IC50 =21.29 μM). This was consistent with apoptosis studies.

Abstract
AbstractOxymaPure [ethyl 2-cyano-2-(hydroxyimino)acetate] is an exceptional reagent with which to suppress racemization and enhance coupling efficiency during amide bond formation. The tremendous popularity of OxymaPure has led to the development of several Oxyma-based reagents. OxymaPure and its derived reagents are widely used in solid- and solution-phase peptide chemistry. This review summarizes the recent developments and applications of OxymaPure and Oxyma-based reagents in peptide chemistry, in particular in solution-phase chemistry. Moreover, the side reaction associated with OxymaPure is also discussed.1 Introduction2 Oxyma-Based Coupling Reagents2.1 Aminium/Uronium Salts of OxymaPure2.2 Phosphonium Salts of OxymaPure2.3 Oxyma-Based Phosphates2.4 Sulfonate Esters of OxymaPure2.5 Benzoate Esters of OxymaPure2.6 Carbonates of OxymaPure Derivatives3 OxymaPure Derivatives4 Other Oxime-Based Additives and Coupling Reagents5 Side Reactions Using OxymaPure Derivatives6 Conclusion7 List of Abbreviations

Abstract
AbstractA new protocol for the oxidative coupling of ketone oximes with dialkyl/diarylphosphine oxides to synthesize O-(dialkylphosphinyl)ketone oximes has been developed. Hydrogen peroxide is used as a green oxidizing agent, and molecular iodine is used as a nonmetal catalyst. The reaction has a high atom economy, with water as the only byproduct. O-(Dialkylphosphinyl)ketone oximes with 26 examples have been obtained with high yields. Furthermore, the product may be transformed into other molecules, i.e., by reduction.

Abstract
Gymnopeptides A and B are unprecedented highly N-methylated cyclic β-hairpin octadecapeptides with striking antiproliferative activities isolated from the mushroom Gymnopus fusipes. Using Fmoc-based solid-phase peptide synthesis, followed by macrolactamization of the resulting linear peptides, the first total synthesis of gymnopeptides A and B was successfully achieved in this study. The coupling methods used for the solid-phase synthesis and the cyclization were optimized, and the configuration of the Ser1/Thr1 residue in gymnopeptide A/B was determined to be l.

Abstract
Here we describe two novel uronium salts, TOMBU and COMBU, derived from the recently described Oxyma-B for use in peptide bond synthesis. These coupling reagents are more stable than COMU in DMF. Furthermore, using various peptide synthetic models in solution and solid-phase synthesis, we reveal that they show better performance than HBTU in terms of preserving chiral integrity and coupling yields, but slightly worse performance than COMU.
