Fluorofenidone Attenuates Renal Interstitial Fibrosis by Enhancing Autophagy and Retaining Mitochondrial Function.

Article

作者: Lu, Miaomiao ; Zhou, Hongli ; Liu, Wenlin ; Xing, Di ; Dong, Haonan

BACKGROUNDFluorofenidone (AKF-PD) is a novel pyridone agent and has potent anti-NLRP3 inflammasome and anti-fibrotic activities. However, the mechanisms underlying its pharmacological actions are not fully understood.METHODSA renal fibrosis rat model was established by the unilateral ureteral obstruction (UUO) procedure and the rats were randomized and treated with, or without, AKF-PD for 3 and 7 days. The levels of renal fibrosis, NLRP3 inflammasome activation, mitochondrial function, and autophagy were tested in rat kidney tissues. Macrophages following lipopolysaccharides (LPS) and adenosine 5'-triphosphate (ATP) stimulation were examined by Western blot, spectrophotometry, and TEM.RESULTSCompared with the untreated UUO rats, AKF-PD treatment significantly mitigated the UUO procedure-induced renal fibrosis in rats. AKF-PD treatment decreased mitochondrial dysfunction and IL-Iβ and caspase-1 expression in rat kidney tissues and reduced mitochondrial reactive oxygen species production in activated macrophages. Mechanistically, AKF-PD treatment significantly attenuated the PI3K/AKT/mTOR signaling, increased Beclin-1 and LC3 II expression and autophagosome formation, and ameliorated the mitochondrial damage in renal tissues and activated macrophages.CONCLUSIONThe results indicated that AKF-PD treatment inhibited renal interstitial fibrosis by regulating the autophagy-mitochondria-NLRP3 inflammasome pathway.

Fluorofenidone enhances cardiac contractility by stimulating CICR and CaV1.2

Article

作者: Ávila, Guillermo

Fluorofenidone (AKF-PD) is a novel pyridone derivative that inhibits fibrosis and inflammation in many tissues. Accordingly, it has been effective in disease models, such as liver failure, nephropathy, and pulmonary fibrosis. However, its potential role in cardiac physiology and pathology has yet to be elucidated. Thus, this paper investigated a possible functional impact of AKF-PD on adult rat cardiac myocytes. Cells were kept in culture for 1-2 days under either control conditions or the presence of AKF-PD (500 μM). They were next examined concerning cell contractility, intracellular Ca²⁺ homeostasis, and activity of voltage-gated Ca²⁺ channels. Remarkably, AKF-PD enhanced the percentage of cell shortening and rates of both contraction and relaxation by nearly 100%. A stimulus in Ca²⁺-induced Ca²⁺ release (CICR) most likely accounts for these effects because AKF-PD also increased the magnitude of electrically evoked Ca²⁺ transients. Of note, the compound did not alter the peak value of caffeine-elicited Ca²⁺ transients, indicating stimulation of CICR at constant sarcoplasmic reticulum Ca²⁺ load. Since CICR is triggered by the entry of Ca²⁺ through Ca_V1.2 (I_Ca), a possible effect on these Ca²⁺ channels was also investigated. AKF-PD increased the magnitude of both I_Ca and maximal macroscopic Ca²⁺ conductance (G_max) by about 50%. However, no differences were found in either voltage dependence of inactivation or the amount of maximal immobilization-resistant charge movement (Q_max). Thus, the effect on I_Ca could be explained by a higher channel's open probability (P_o) rather than a greater abundance of channel proteins. Additional data indicate that AKF-PD reduces the rate of Ca²⁺ extrusion in the presence of caffeine, suggesting inhibition of the Na/Ca exchanger. Overall, these results indicate that AKF-PD upregulates the P_o of Ca_V1.2 and then sequentially enhances I_Ca, CICR, and contractility. Therefore, the novel compound is also a candidate to be tested in cardiac disease models.

Complexation of Fluorofenidone by Cucurbit[7]uril and β-Cyclodextrin: Keto-Enol Tautomerization to Enhance the Solubility.

Article

作者: Lu, Tong-Bu ; Chen, Hua-Yu ; Huang, Yong-Liang ; Chen, Jia-Mei ; Ma, Wen-Juan

This study is designed to compare drug encapsulation by cucurbit[7]uril and β-cyclodextrin, using fluorofenidone as a model drug. Single-crystal X-ray diffraction analysis was employed to successfully determine the crystal structures of fluorofenidone·H⁺@cucurbit[7]uril Form, fluorofenidone@cucurbit[7]uril Form, and fluorofenidone@β-cyclodextrin Form. Keto-enol tautomerization of fluorofenidone mediated by cucurbit[7]uril in acid solution is confirmed by crystal structures, pH titration, and nuclear magnetic resonance experiments. However, β-cyclodextrin cannot cause the keto-enol tautomerization of fluorofenidone under similar conditions. The phase solubility study demonstrates that cucurbit[7]uril has a much higher solubilization capacity for fluorofenidone than β-cyclodextrin in 0.1 M HCl since the K_c values of fluorofenidone with cucurbit[7]uril and β-cyclodextrin were 1223.97 ± 452.68 and 78.49 ± 10.56 M^-1, respectively. Excellent solubility can be attributed to the keto-enol tautomerization of fluorofenidone under the conditions of cucurbit[7]uril in acid solution. The enol form of fluorofenidone is encapsulated by cucurbit[7]uril by hydrogen bonding interaction and hydrophobic interaction to increase binding affinity. Rat pharmacokinetic studies demonstrate that the area under the plasma concentration-time curve from time 0 to 7 h value of fluorofenidone@cucurbit[7]uril complex is 1.70-fold greater than that of free fluorofenidone, and the mean residence time from time 0 to 7 h is slightly prolonged from 1.29 to 1.76 h (P < 0.01) after oral administration. However, no significant difference is found between fluorofenidone and fluorofenidone@β-cyclodextrin complex. This work indicates that the induction of keto-enol tautomerization of drugs using macrocyclic molecules has the potential to be an effective method to improve their solubility and bioavailability, providing valuable insights for the application of macrocyclic molecules in the biomedical field.
