Colloids and Interfaces

A 2D imine-linked covalent organic framework (COF) with good biocompatibility was synthesized using o-Dianisidine and 1,3,5-Triformylbenzene. The synthesized COF was characterized by using the Fourier transform infrared (FTIR), thermogravimetry analysis (TGA), scanning electron microscopy (SEM), and transmission electron microscopy (TEM). The synthesized COF was subsequently utilized for the delivery of gemcitabine (Gem), an FDA-approved drug for the treatment of pancreatic cancer. The COF demonstrated a remarkable drug loading of 30 µg/mg and better drug release at pH 5.0. The biocompatibility of the COF was evaluated in the L929 (mouse fibroblast) cell line, while the cytotoxicity of the Gem-loaded COF (COF-Gem) was evaluated against the MIA-PaCa-2 and PANC-1 (pancreatic cancer) cell lines using MTT (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide) assay. The results indicated that the COF was safe at concentrations up to 200 µg/mL, while the COF-Gem led to superior cytotoxicity as compared to native Gem, with IC50 values of 8.1 ± 1.2 µM in MIA-PaCa-2 cells and 6.0 ± 1.3 µM in PANC-1 cells after 48 h. This study offers a new perspective of utilizing COF as a promising delivery system for Gem delivery.

Gemcitabine (GEM), a chemotherapeutic agent, is widely used to treat various neoplastic conditions, such as pancreatic, lung, breast, and ovarian cancer. However, its therapeutic effectiveness is often hindered by its short half‐life and susceptibility to enzymatic degradation. To address these limitations, in this research, five new conjugates of GEM were synthesized by conjugating its N‐4 amino group with five different acids [4‐decenoic acid (4Dec), lipoic acid (Lipo), lauric acid (Laur), 5‐benzyl N‐(tert‐butoxycarbonyl)‐ L‐glutamate (Glu), and decanoic acid (Dec)]. The anticancer potential of these conjugates was evaluated using CCK‐8 assay. Among the synthesized conjugates, 4Dec‐GEM demonstrated comparable cytotoxic activity to native GEM. The mechanistic insight of 4Dec‐GEM was investigated using annexin‐V FITC/propidium iodide staining, reactive oxygen species generation, and mitochondrial membrane potential loss assays. To further enhance its therapeutic efficacy, 4Dec‐GEM was encapsulated into poly(lactic‐co‐glycolic acid) (PLGA) nanoparticles using single‐emulsion method using high‐pressure homogenization. The developed nanoparticles were characterized by various techniques (TEM, FT‐IR, DSC, p‐XRD) and demonstrated successful entrapment of 4Dec‐GEM inside PLGA nanoparticles. Finally, the cytotoxicity of developed nanoparticles demonstrated improved anticancer activity as compared to native GEM in cancerous cell lines. Our study demonstrated that the combination of prodrug and nanoparticle approach can be a promising approach to augment the therapeutic efficacy of GEM.

In this study, a hybrid conjugate of formononetin (FMN) and vitamin E (VESylated‐FMN) was synthesized through succinic acid linker and investigated for its synergistic effect in diabetes. The conjugate was characterized through Ultra Performance Liquid Chromatography – Mass Spectrometry (UPLC‐MS), High‐Resolution Mass Spectrometry (HRMS), Nuclear Magnetic Resonance (NMR), and Differential Scanning Calorimetry (DSC). The ability of VESylated‐FMN to promote adipogenesis and ameliorate insulin resistance brought on by oxidative stress was evaluated in differentiated preadipocytes. Interestingly, VESylated‐FMN promoted intracellular glucose absorption, which in turn increased lipid and triglyceride accumulation and thereby encouraged adipogenesis. VESylated‐FMN attenuated oxidative stress and promoted cell survival by reducing reactive oxygen species (ROS) generation and reversing apoptosis. Additionally, VESylated‐FMN improved insulin sensitization by upregulating the gene and protein expression of insulin‐sensitizing markers. Overall, FMN in conjugation with vitamin E can effectively augment prior insulin sensitivity by reducing oxidative stress for efficient glycemic control in hyperglycemia.

... The synthesized COF was further explored for the delivery of Gemcitabine (Gem), a pyrimidine nucleoside analog. Gem is widely used, either alone or in combination with other chemotherapeutic agents or radiation therapy, to treat a range of cancers, including pancreatic, ovarian, bladder, breast, and non-small-cell lung cancers [24]. Further, Gem exhibits poor loading efficiency when entrapped into polymeric and lipid-based nanoparticles. ...

... In a rodent model of epilepsy induced by pentylenetetrazol via an Nrf2 pathway, treatment with ALA improved behavioral dysfunction and significantly reduced the number of epileptic seizures . Unfortunately, as a drug candidate, ALA has poor pharmacokinetic properties that limit its therapeutic potential (Kumari et al., 2022;Salehi et al., 2019;Steliou et al., 2015;Usacheva et al., 2022). Ongoing efforts in design and chemical synthesis aim to overcome these deficiencies using ALA prodrugs prepared from analogues, derivatives or conjugates as potential therapeutics with more favorable pharmacological properties (Javaid et al., 2022;Kong et al., 2022;Kumari et al., 2022;Lv et al., 2022;Moos et al., 2022;Steliou et al., 2015;Wang et al., 2020;Zielonka et al., 2017). ...
