Abstract

complex of dimethyl[(4-benzhydrylpiperazin-1-yl)(2-fluorophenyl)methyl]phosphonate with beta-Cyclodextrin ((<bold><italic>o</italic>-Fph</bold>)<bold>PPh beta CD</bold>)

immunomodulation

Acute pneumonia is frequently accompanied by immune suppression, particularly affecting T-cell subsets, such as CD4+, CD4+CD25+, and CD4+CD25+FoxP3+, which are critical for immune regulation. This study evaluates the immunomodulatory potential of a novel fluorinated piperazine-based aminophosphonate, complexed with β-cyclodextrin ((o-Fph)PPhβCD), comparing it with the clinically approved agent Polyoxidonium (PO) in a rat model of oleic acid-induced acute pneumonia. Flow cytometric analysis revealed that (o-Fph)PPhβCD significantly restored CD4+ and CD4+CD25+ T-cell levels and induced a sustained reduction in regulatory CD4+CD25+FoxP3+ cells, suggesting enhanced effector immune activity. While PO provided early immunorestorative effects, (o-Fph)PPhβCD exerted a more prolonged response, which was particularly evident by day 14. Structural confirmation of the inclusion complex was achieved through IR and NMR spectroscopy. These findings highlight (o-Fph)PPhβCD as a promising immunotherapeutic candidate that is capable of rebalancing immune cell populations and supporting host defense mechanisms during acute pulmonary inflammation.
