[PMID: 38704941 DOI: 10.1016/j.ejmech.2024.116457] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/21/2024] [Revised: 04/20/2024] [Accepted: 04/25/2024] [Indexed: 05/07/2024]
Abstract
It is well-known that pharmacotherapy plays a pivotal role in the treatment and prevention of cerebral ischemia. Nevertheless, existing drugs, including numerous natural products, encounter various challenges when applied in cerebral ischemia treatment. These challenges comprise poor brain absorption due to low blood-brain barrier (BBB) permeability, limited water solubility, inadequate bioavailability, poor stability, and rapid metabolism. To address these issues, researchers have turned to prodrug strategies, aiming to mitigate or eliminate the adverse properties of parent drug molecules. In vivo metabolism or enzymatic reactions convert prodrugs into active parent drugs, thereby augmenting BBB permeability, improving bioavailability and stability, and reducing toxicity to normal tissues, ultimately aiming to enhance treatment efficacy and safety. This comprehensive review delves into multiple effective prodrug strategies, providing a detailed description of representative prodrugs developed over the past two decades. It underscores the potential of prodrug approaches to improve the therapeutic outcomes of currently available drugs for cerebral ischemia. The publication of this review serves to enrich current research progress on prodrug strategies for the treatment and prevention of cerebral ischemia. Furthermore, it seeks to offer valuable insights for pharmaceutical chemists in this field, offer guidance for the development of drugs for cerebral ischemia, and provide patients with safer and more effective drug treatment options.

Comparative pharmacokinetics of 11 major bioactive components between two dosage forms of Qixue Shuangbu Prescription in rats by ultra-high-performance liquid chromatography-tandem mass spectrometry. J Sep Sci 2024; 47:e2300677. [PMID: 37994256 DOI: 10.1002/jssc.202300677] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/22/2023] [Revised: 11/02/2023] [Accepted: 11/10/2023] [Indexed: 11/24/2023]
Abstract
Although Qixue Shuangbu Prescription (QSP) is a classic Chinese medicine prescription for treating chronic heart failure. Low bioavailability due to the insolubility and poor biofilm permeability of the main bioactive ingredients of QSP is still a key factor limiting its efficacy. In this study, a novel self-microemulsifying drug delivery system was proposed to effectively improve the bioavailability of QSP. The qualified ultra-high-performance liquid chromatography-tandem mass spectrometry methodology was established to investigate the pharmacokinetics characteristics of the QSP self-microemulsifying drug delivery system. Our results showed that 11 components in the self-microemulsifying drug delivery system group had prolonged T1/2 and MRT0-t values compared with QSP extract. The Cmax of calycosin-7-glucoside (CG), vanillic acid and paeoniflorin increased 2.5 times, 2.4 times and 2.3 times, respectively. The relative bioavailability values of CG, paeoniflorin and ononin were most significantly affected, increasing by 383.2%, 336.5% and 307.1%, respectively. This study promoted the development of new dosage forms of QSP and provided a useful reference for improving dosage forms to solve the problem of low bioavailability of traditional Chinese medicine.

Abstract
PURPOSE Febuxostat is a non-purine xanthine oxidase inhibitor which belongs to the BCS class II. Main aim of this study is to enhance dissolution and bioavailability of a drug by formulating a liquid self-micro emulsifying drug delivery system (SMEDDS) in different capsule shells. METHOD Compatability of gelatin and cellulose capsule shells was checked with different oils, surfactants and co-surfactants. Solubility studies were then carried out in selected excipients. Capryol 90, labrasol, and PEG 400 were used in a liquid SMEDDS formulation based on phase diagram and the drug loading. Further SMEDDS was characterized for zeta potential, globule size and shape, thermal stability and in vitro release. Based on the in vitro release, pharmacokinetic study was carried out using SMEDDS in gelatin capsule shells. RESULT The diluted SMEDDS had globule size of 157.9±1.5d.nm, zeta potential of -16.2±0.4mV and they were thermodynamically stable. The formulation was found stable for 12 months in capsule shells. When tested in different media (0.1N HCl and pH 4.5 acetate buffer), the in vitro release of newly produced formulations differed substantially from that of commercially available tablets, while the release rate in alkaline medium (pH 6.8) was comparable and the highest. According to in vivo findings in rats, a threefold increase in plasma concentration, a fourfold increase in AUC0-t, and a reduction in oral clearance increased fuxostat's oral bioavailability. CONCLUSION This investigation revealed that the novel liquid SMEDDS formulation sealed in capsules has considerable potential as a vehicle for enhancing the bioavailability of febuxostat.

Abstract
Anethol trithione (ATT) has a wide range of physiological activities, but its use is limited due to its poor water solubility. To improve the solubility of ATT, we synthesized and characterized a novel phosphate prodrug (ATXP) relying on the availability of the hydroxy group in 5-(4-hydroxyphenyl)-3H-1,2-dithiole3-thione (ATX), which was transformed from ATT rapidly and extensively in vivo. Our results showed that ATXP significantly improved drug solubility. ATXP was rapidly converted to ATX and reached a maximum plasma concentration with a T max of approximately 5 min after intravenous (iv) administration. Furthermore, after the oral administration of ATXP, the C max was 3326.30 ± 566.50 ng/mL, which was approximately 5-fold greater than that of the parent drug form, indicating that ATXP has greater absorption than that of ATT. Additionally, the oral phosphate prodrug ATXP increased the ATX in the area under the plasma concentration vs time curves (AUC0-t = 3927.40 ± 321.50 and AUC0-∞ = 4579.0 ± 756.30), making its use in practical applications more meaningful. Finally, compared to the vehicle, ATXP was confirmed to maintain the bioactivity of the parent drug for a significant reduction in infarct volume 24 h after reperfusion. Based on these findings, the phosphate prodrug ATXP is a potentially useful water-soluble prodrug with improved pharmacokinetic properties.

Abstract
In this study, an examination of the potential effect of lipids on the first-pass metabolism of anethol trithione (ATT) was investigated. ATT is metabolized rapidly and extensively in liver into 4-hydroxy-anethole trithione (ATX), which was confirmed using the rat intestinal perfusion with the mesenteric cannulation model. Male Sprague-Dawley rats were orally administered of the lipid-based formulations (prepared by medium chain triglycerides (MCT)), the cyclodextrin formulation and the suspension formulation, respectively. For 6.75 mg/kg groups, ATX/ATT area under the plasma concentration-time curve (AUC) ratio decreased by 87% and 76% after administration of the MCT-based formulations and the cyclodextrin formulation, when compared with the suspension formulation (p < 0.05), respectively; for 2.25 mg/kg groups, it decreased by 53% in the MCT group when compared with the cyclodextrin group (p < 0.05). The saturation of pre-system metabolism of ATT was observed after administration of the MCT-based formulations and the cyclodextrin formulation, likely as a result of enhanced absorption and therefore presentation of higher drug concentrations to liver, when compared with the suspension formulation. A trend toward lower systemic metabolite to parent ratios was evident after administration of the lipid formulations, when compared with the cyclodextrin formulation; however, this was not statistically significant. Further studies on the potential for lipids to inhibit hepatic metabolism are therefore warranted.

Abstract
A selective, rapid and sensitive method for the quantitation of 4-hydroxy-anethole trithione (ATX) in human plasma based on high-performance liquid chromatography-tandem mass spectrometry (HPLC-MS/MS) was developed and validated. Paracetamol was used as the internal standard (I.S.). After liquid-liquid extraction of 500 μL plasma with ethyl acetate, ATX and the I.S. were chromatographed on an Inertsil(®) ODS-3 column. The mobile phase was consisted of methanol-water (75:25, v/v) with a flow rate of 0.25 mL/min. The detection was performed on a triple quadrupole tandem mass spectrometer by multiple reaction monitoring (MRM) mode via electrospray ionization (ESI) source. The calibration curve was linear over the range of 0.452-603 ng/mL (r(2)≥0.99) with a lower limit of quantitation (LLOQ) of 0.452 ng/mL. The intra- and inter-day precision (relative standard deviation, R.S.D.) values were below 13% and the accuracy (relative error, R.E.) was from -2.7% to -7.5% at three quality control levels. The assay herein described was successfully applied to a pharmacokinetic study of anethole trithione (ATT) tablet in healthy volunteers after oral administration.

Abstract
Cefpodoxime proxetil (CP) is a prodrug, the third generation cephem-type broad-spectrum antibiotic administered orally. However, CP was found to be a poorly water-soluble drug with low bioavailability when orally administered. In the present investigation, the spray-dried cefpodoxime proxetil nanosuspension (SDN) was prepared. The physicochemical properties were characterized by rheological evaluation, particle size measurement and its distribution, dynamics of reconstitution, in-vitro dissolution testing, surface morphology, surface area and pore size measurements. The pharmacokinetic study of SDN, in comparison to a marketed cefpodoxime proxetil for oral suspension (MS), was also performed in rabbits after a single oral dose. It was found that SDN exhibited a significant decrease in t(max), a 1.60-fold higher area under curve (AUC) and 2.33-fold higher maximum plasma concentration (C(max)) than MS.

Abstract
A panel of new drugs obtained by grafting a sulfurated moiety, i.e. 5-(4-hydroxyphenyl)-3H-1,2-dithiole-3-thione (ADTOH) onto existing drugs have been synthesized and their in vivo action is under preclinical evaluation. In the present paper we describe rapid HPLC methods to detect ADTOH derivatives of valproic acid (ACS2), sildenafil (ACS6), aspirin (ACS14) and diclofenac (ACS15) in plasma. These methods allow the simultaneous detection of the potential drugs and of ADTOH moiety. In the case of ACS14 the de-acetylated metabolite (ACS21) can also be concomitantly measured. The chromatographic separation was performed on a C18 column, applying a mobile phase consisting of a mixture of trifluoroacetic acid and acetonitrile. ADTOH, ACS6, ACS14, ACS21 were separated isocratically whereas ACS2 and ACS15 were separated applying gradient elution. The methods are precise and accurate, with a low quantification limit of 200 nM for ACS2, ACS15 and ACS21 or 100 nM for ADTOH, ACS6 and ACS14. The mean absolute recovery for all tested molecules was always found to be close to 100%. The methods are shown to be selective and linear in the range 0.2-50 microM and thus appear suitable for pharmacokinetic studies with ADTOH containing compounds, as indicated by exemplificative experiments performed with intravenous administration of the drugs to rats.

Abstract
A rapid, sensitive and reliable high performance liquid chromatographic method coupled with tandem mass spectrometry via electrospray ionization (ESI) source (HPLC-MS/MS) has been developed and validated for the determination of anethole trithione (ATT) in human plasma. Diazepam was employed as the internal standard (IS). Sample extracts following liquid-liquid extraction were injected into the HPLC-MS/MS system. The analyte and IS were eluted isocratically on a C18 column, with a mobile phase consisting of methanol and aqueous ammonium acetate solution (5 mM) (80:20, v/v) . The ions were detected by a triple quadrupole mass spectrometric detector in the positive mode. Quantification was performed using selected reaction monitoring (SRM) of the transitions m/z 240.88-->197.91 and m/z 285.01-->193.02 for ATT and for the IS, respectively. The analysis time for each run was 5.0 min. The calibration curve fitted well over the concentration range of 0.02-5 ng mL(-1), with the regression equation y = 1.1014x + 0.0003631, r = 0.9992. The intra-batch and inter-batch R.S.D.% were less than 15% at all concentration levels within the calibration range. The recoveries were more than 80%. The present method provides a modern, rapid and robust procedure for the pharmacokinetic study of ATT. Some important pharmacokinetic parameters of ATT in healthy Chinese volunteers are also given for the first time.
