Abstract: Transdermal drug delivery systems present a promising alternative to oral administration, though improving skin permeability of active pharmaceutical ingredients (APIs) remains challenging. This study examines how various electromagnetic fields (EMFs) affect the transdermal permeability of naproxen (NAP) and its physicochemical properties. Using pigskin as a model, NAP permeability was tested under oscillating, pulsed, static, and rotating magnetic fields (RMF), compared to a control group without EMF exposure. The results show significant differences in NAP permeability depending on EMF type, with RMF at 50 Hz yielding the highest cumulative permeation mass (CPM) of 1461.40 ± 256.15 µg/cm2, compared to 267.57 ± 41.74 µg/cm2 for the control. RMF 50 Hz also maximized steady-state flux (JSS) and permeability coefficient (Kp), highlighting its potential for enhanced transdermal delivery. Conversely, static magnetic fields with negative polarization reduced permeation, showing a complex interaction between magnetic fields and skin permeability. The study also found that RMF treatments lowered NAP skin accumulation, improving permeation efficiency. Physicochemical analyses (FTIR, XRD, solubility, and lipophilicity) revealed that while EMF exposure did not significantly change NAP's crystal structure, it did affect solubility and partition coefficient. This research highlights the potential of optimizing EMF parameters to enhance transdermal drug delivery and provides insights into the physicochemical interactions between EMFs and active compounds. The findings suggest that rotating magnetic fields, particularly at 50 Hz, offer the most significant improvement in drug permeability, which could be beneficial for developing advanced transdermal delivery systems.

Abstract: In the study, the modification of (NAP) with esters of four amino acids (AAs): (GlyOiPr), (ProOiPr), (LeuOiPr), and (SerOiPr) isopropyl ester was performed to improve water solubility and enhance the permeation of the drug through the skin in comparison to the parent NAP. The NAP derivatives were prepared using the equimolar ratio of the components. In-depth NMR and FTIR analysis revealed that the salts formed with the proton transfer from the carboxylic group of NAP to the amine group of the appropriate AA ester. The NAP salts exhibited improved solubility in water and PBS solution (pH 7.4) when compared to parent NAP. The values of the partition coefficient (log PO/W) for prepared salts were lower than for NAP, however, the salts maintained hydrophobic character determined by the positive values of log P. The In vitro permeation through the pig skin performed in Franz diffusion cells showed that all NAP salts exhibited a higher cumulative mass of permeated NAP (Q24h) than the parent acid. The highest permeation value was noted for [ProOiPr][NAP], with a pseudo-steady state flux (Jss) 32.5 µg NAP cm−2h−1, and Q24h = 246.4 µg NAP cm−2, it was 2.5 % of the applied dose. Moreover, topical preparations with [ProOiPr][NAP] and NAP were prepared based on two vehicles − Celugel® and Pentravan®- approved in pharmacy recipes. The permeation experiments through the Strat-M® showed, that both the Jss and Q24h of permeated drug from preparations containing [ProOiPr][NAP], were statistically several times greater than from the respective preparations with the unmodified acid. Additionally, preparations with [ProOiPr][NAP] provided significantly improved permeation of NAP than two commercial preparations, one of which contained as the acid and the other - as the sodium salt.

Abstract: OATP1C1 (organic anion-transporting polypeptide 1C1) transports thyroid hormones, particularly thyroxine (T4), into human astrocytes. In this study, we investigated the potential of utilizing OATP1C1 to improve the delivery of anti-inflammatory drugs into glial cells. We designed and synthesized eight novel prodrugs by incorporating T4 and 3,5-diiodo-L-tyrosine (DIT) as promoieties to selected anti-inflammatory drugs. The prodrug uptake in OATP1C1-expressing human U-87MG glioma cells demonstrated higher accumulation with T4 promoiety compared to those with DIT promoiety or the parent drugs themselves. In silico models of OATP1C1 suggested dynamic binding for the prodrugs, wherein the pose changed from vertical to horizontal. The predicted binding energies correlated with the transport profiles, with T4 derivatives exhibiting higher binding energies when compared to prodrugs with a DIT promoiety. Interestingly, the prodrugs also showed utilization of oatp1a4/1a5/1a6 in mouse primary astrocytes, which was further supported by docking studies and a great potential for improved brain drug delivery.

Abstract: Herein, we investigated the effect of pairing the L-amino acid alkyl (Pr, iso-Pr, or butyl) ester on the formation of API-ILs. The novel salts of NSAIDs (non-steroidal anti-inflammatory drugs) obtained from biodegradable cations were synthesized and characterised by NMR (NMR), Fourier transform IR spectroscopy (FT-IR), and X-ray powder diffraction (XRD) methods. The influence of structure counterions for APIs from the NSAIDs group on their physicochem. properties was studied in detail. The comprehensive effects of cation structure on skin permeation, accumulation, and antioxidant activity of API-ILs were also evaluated. These results demonstrated that L-amino acid alkyl esters can be successfully used to synthesize API-ILs further used in topical formulations with anti-ageing, anti-inflammatory, or photoprotective effects.

Abstract: The paper presents a method of increasing the permeability of various active substances through the skin by means of a rotating magnetic field. The study used 50 Hz RMF and various active pharmaceutical ingredients (APIs) such as caffeine, ibuprofen, naproxen, ketoprofen, and paracetamol. Various concentrations of active substance solutions in ethanol were used in the research, corresponding to those in com. preparations Each experiment was conducted for 24 h. It was shown that, regardless of the active compound used, an increase in drug transport through the skin was observed with RMF exposure. Furthermore, the release profiles depended on the active substance used. Exposure to a rotating magnetic field has been shown to effectively increase the permeability of an active substance through the skin.

Abstract: The paper presents the synthesis, full identification, and characterization of new salts-L-proline alkyl ester naproxenates [ProOR][NAP], where R was a chain from Et to Bu (including isopropyl). All obtained compounds were characterized by NMR (NMR), Fourier transform IR spectroscopy (FTIR), X-ray powder diffractometry (XRD), and in vitro dissolution studies. The sp. rotation, phase transition temperatures (m.p.), and thermal stability were also determined In addition, their lipophilicity, permeability, and accumulation in pigskin were determined Finally, toxicity against mouse L929 fibroblast cells was tested. The obtained naproxen derivatives showed improved solubility and higher absorption of drug mols. by biol. membranes. Their lipophilicity was lower and increased with the increase in the alkyl chain of the ester. The derivative with iso-Pr ester had the best permeability through pigskin. The use of L-proline iso-Pr ester naproxenate increased the permeation of naproxen through the skin almost four-fold. It was also shown that the increase in permeability is not associated with addnl. risk: all compounds had a similar effect on cell viability as the parent naproxen.
