Abstract
In this current research, we conceptualized a novel nanotechnology-enabled synthesis approach of targeting HIV-harboring tissues via second-generation (G2) polyamidoamine (PAMAM) mannosylated (MPG2) dendrimers for programmed delivery of anti-HIV drugs efavirenz (EFV) and ritonavir (RTV). Briefly, here mannose served purpose of ligand in this EFV and RTV-loaded PAMAM G2 dendrimers, synthesized by divergent techniques, denoted as MPG2ER. The developed nanocarriers were characterized by different analytical tools FTIR, NMR, zeta potential, particle size, and surface morphology. The results of confocal microscopy showed substantial alterations in the morphology of H9 cells, favored by relatively higher drug uptake through the MPG2ER. Interestingly, the drug uptake study and cytotoxicity assay of MPG2ER demonstrated that it showed no significant toxicity up to 12.5 µM. A typical flow cytometry histogram also revealed that MPG2ER efficiently internalized both drugs, with an increase in drug uptake of up to 81.2 %. It also enhanced the plasma pharmacokinetics of EFV, with Cmax7.68 μg/ml, AUC of 149.19 (μg/ml) * hr, and MRT of 26.87 hrs. Subsequently, tissue pharmacokinetics further evidence that MPG2ER accumulated more in distant Human immunodeficiency virus (HIV) reservoir tissues, such as the lymph nodes and spleen, but without exhibiting significant toxicity. Abovementioned compelling evidences strongly favored translational roles of MPG2 as a potential therapeutic strategy in the clinical eradication of HIV from viral reservoir tissue.
