Ganoderenic acid D-loaded functionalized graphene oxide-based carrier for active targeting therapy of cervical carcinoma. Biomed Pharmacother 2023; 164:114947. [PMID: 37269813 DOI: 10.1016/j.biopha.2023.114947] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/13/2023] [Revised: 05/23/2023] [Accepted: 05/26/2023] [Indexed: 06/05/2023] Open
Abstract
Ganoderenic acid D (GAD), extracted from the Chinese herb Ganoderma lucidum, was loaded onto a graphene oxide-polyethylene glycol-anti-epidermal growth factor receptor (GO-PEG-EGFR) carrier to develop a targeting antitumor nanocomposite (GO-PEG@GAD). The carrier was fabricated from PEG and anti-EGFR aptamer modified GO. Targeting was mediated by the grafted anti-EGFR aptamer, which targets the membrane of HeLa cells. Physicochemical properties were characterized by transmission electron microscopy, dynamic light scattering, X-ray powder diffraction, and Fourier transform infrared spectroscopy. High loading content (77.3 % ± 1.08 %) and encapsulation efficiency (89.1 % ± 2.11 %) were achieved. Drug release continued for approximately 100 h. The targeting effect both in vitro and in vivo was confirmed by confocal laser scanning microscopy (CLSM) and imaging analysis system. The mass of the subcutaneous implanted tumor was significantly decreased by 27.27 ± 1.23 % after treatment with GO-PEG@GAD compared with the negative control group. Moreover, the in vivo anti-cervical carcinoma activity of this medicine was due to activation of the intrinsic mitochondrial pathway.

Abstract
Efficient delivery of adequate active ingredients to targeted malignant cells is critical, attributing to recurrent biophysical and biochemical challenges associated with conventional pharmaceutical delivery systems. These challenges include drug leakage, low targeting capability, high systemic cytotoxicity, and poor pharmacokinetics and pharmacodynamics. Targeted delivery system is a promising development to deliver sufficient amounts of drug molecules to target cells in a controlled release pattern mode. Aptameric ligands possess unique affinity targeting capabilities which can be exploited in the design of high pay-load drug formulations to navigate active molecules to the malignant sites. This study focuses on the development of a copolymeric and multifunctional drug-loaded aptamer-conjugated poly(lactide-co-glycolic acid)-polyethylenimine (PLGA-PEI) (DPAP) delivery system, via a layer-by-layer synthesis method, using a water-in-oil-in-water double emulsion approach. The binding characteristics, targeting capability, biophysical properties, encapsulation efficiency, and drug release profile of the DPAP system were investigated under varying conditions of ionic strength, polymer composition and molecular weight (MW), and degree of PEGylation of the synthetic core. Experimental results showed increased drug release rate with increasing buffer ionic strength. DPAP particulate system obtained the highest drug release of 50% at day 9 at 1 M NaCl ionic strength. DPAP formulation, using PLGA 65:35 and PEI MW of ∼800 Da, demonstrated an encapsulation efficiency of 78.93%, and a loading capacity of 0.1605 mg bovine serum albumin per mg PLGA. DPAP (PLGA 65:35, PEI MW∼25 kDa) formulation showed a high release rate with a biphasic release profile. Experimental data depicted a lower targeting power and reduced drug release rate for the PEGylated DPAP formulations. The outcomes from the present study lay the foundation to optimize the performance of DPAP system as an effective synthetic drug carrier for targeted delivery.
