Abstract
Efficient routes for the preparation of functional self-healing hydrogels from functional polymers are needed. In this study, we developed a strategy to effectively produce a vanillin-modified poly(vinyl alcohol) (PVA-vanillin) through the Hantzsch reaction. This polymer was cross-linked with a phenylboronic acid-containing polymer (PB) that was also prepared using the Hantzsch reaction to fabricate a hydrogel through borate ester linkages under mild conditions (25 °C, pH ∼ 7.4). This hydrogel had excellent antioxidant abilities due to the 1,4-dihydropyridine (DHP) rings and the vanillin moieties in the hydrogel structures; it was also self-healable and injectable owing to the dynamic borate ester linkages. Furthermore, the antioxidant self-healing hydrogel had low cytotoxicity and exhibited favorable safety in animal experiments, indicating its potential as a safe implantable cell or drug carrier. This study developed a method for preparing functional polymers and related self-healing hydrogels in a facile manner; it demonstrated the value of the Hantzsch reaction in exploiting antioxidant self-healing hydrogels for biomedical applications, which may provide insight into the design of other functional self-healing hydrogels through different multicomponent reactions.

Abstract
An efficient 1,4-dihydropyridine synthesis under mild conditions has been developed. Numerous substrates were tested, with yields of 1,4-dihydropridines ranging from good to excellent and a wide range of functional group tolerance. A549, HT-29, and HepG2 cancer cells were used to investigate the anticancer efficacy of each of the produced compounds. Additionally, in-silico docking studies were conducted to understand the structure-based features of the anticancer mechanism with the cancer medication target of Adenosine A2A receptor as well as the molecular level interactions of the compounds.

ACS OMEGA 2021; 6:23621-23629. [PMID: 34549160 PMCID: PMC8444320 DOI: 10.1021/acsomega.1c03872] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/21/2021] [Accepted: 08/19/2021] [Indexed: 05/22/2023]
Abstract
The purpose of this study is to investigate thermodynamic and kinetic properties on the hydrogen-atom-donating ability of 4-substituted Hantzsch ester radical cations (XRH•+), which are excellent NADH coenzyme models. Gibbs free energy changes and activation free energies of 17 XRH•+ releasing H• [denoted as ΔG HD o(XRH•+) and ΔG HD ≠(XRH•+)] were calculated using density functional theory (DFT) and compared with that of Hantzsch ester (HEH2) and NADH. ΔG HD o(XRH•+) range from 19.35 to 31.25 kcal/mol, significantly lower than that of common antioxidants (such as ascorbic acid, BHT, the NADH coenzyme, and so forth). ΔG HD ≠(XRH•+) range from 29.81 to 39.00 kcal/mol, indicating that XRH•+ spontaneously releasing H• are extremely slow unless catalysts or active intermediate radicals exist. According to the computed data, it can be inferred that the Gibbs free energies and activation free energies of the core 1,4-dihydropyridine radical cation structure (DPH•+) releasing H• [ΔG HD o(DPH•+) and ΔG HD ≠(DPH•+)] should be 19-32 kcal/mol and 29-39 kcal/mol in acetonitrile, respectively. The correlations between the thermodynamic driving force [ΔG HD o(XRH•+)] and the activation free energy [ΔG HD ≠(XRH•+)] are also explored. Gibbs free energy is the important and decisive parameter, and ΔG HD ≠(XRH•+) increases in company with the increase of ΔG HD o(XRH•+), but no simple linear correlations are found. Even though all XRH•+ are judged as excellent antioxidants from the thermodynamic view, the computed data indicate that whether XRH•+ is an excellent antioxidant in reaction is decided by the R substituents in 4-position. XRH•+ with nonaromatic substituents tend to release R• instead of H• to quench radicals. XRH•+ with aromatic substituents tend to release H• and be used as antioxidants, but not all aromatic substituted Hantzsch esters are excellent antioxidants.

[DOI: 10.2174/1389557519666190425184749] [Citation(s) in RCA: 23] [Impact Index Per Article: 4.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/21/2018] [Revised: 03/08/2019] [Accepted: 04/02/2019] [Indexed: 12/17/2022]
Abstract
:
Nowadays, heterocyclic compounds act as a scaffold and are the backbone of medicinal
chemistry. Among all of the heterocyclic scaffolds, 1,4-Dihydropyridine (1,4-DHP) is one of the most
important heterocyclic rings that possess prominent therapeutic effects in a very versatile manner and
plays an important role in synthetic, medicinal, and bioorganic chemistry. The main aim of the study is
to review and encompass relevant studies related to 1,4-DHP and excellent therapeutic benefits of its
derivatives. An extensive review of Pubmed-Medline, Embase and Lancet’s published articles was
done to find all relevant studies on the activity of 1,4-DHP and its derivatives. 1,4-DHP is a potent
Voltage-Gated Calcium Channel (VGCC) antagonist derivative which acts as an anti-hypertensive, anti-
anginal, anti-tumor, anti-inflammatory, anti-tubercular, anti-cancer, anti-hyperplasia, anti-mutagenic,
anti-dyslipidemic, and anti-ulcer agent. From the inferences of the study, it can be concluded that the
basic nucleus, 1,4-DHP which is a voltage-gated calcium ion channel blocker, acts as a base for its derivatives
that possess different important therapeutic effects. There is a need of further research of this
basic nucleus as it is a multifunctional moiety, on which addition of different groups can yield a better
drug for its other activities such as anti-convulsant, anti-oxidant, anti-mutagenic, and anti-microbial.
This review would be significant for further researches in the development of several kinds of drugs by
representing successful matrix for the medicinal agents.
