Abstract
B vitamins and probiotics are commonly used dietary supplements with well-documented health benefits. However, their potential interactions remain poorly understood. This study aims to explore the effects and underlying mechanisms of the combined use of B vitamins and probiotics by liquid chromatography-triple quadrupole mass spectrometry analysis, pharmacokinetic modeling, and 16S rRNA gene sequencing. By intragastric administration of seven B vitamins and three Lactobacillus strains to healthy rats (n = 8 per group), we found that probiotics significantly promoted the absorption (by approximately 14.5% to 71.2%) of vitamins B1, B3, B5, and B12. By conducting in vitro experiments (n = 3 per group) and a pseudo-germ-free rat model-based pharmacokinetic study (n = 6 per group), we confirmed that probiotics primarily enhanced the B vitamin absorption through gut microbiota-mediated mechanisms, rather than by directly producing B vitamins. Furthermore, we evaluated the effects of B vitamins and probiotics on the colon and gut microbiota by treating the pseudo-germ-free rats with blank solution, B vitamins, probiotics, and B vitamins + probiotics (n = 5 per group), respectively. Histopathological examination showed that the combination of B vitamins and probiotics synergistically alleviated the rat colon damage. High-throughput genetic sequencing also revealed the synergistic effect of B vitamins and probiotics in modulating the gut microbiota, particularly increasing the abundance of Verrucomicrobia and Akkermansia. In summary, the combined administration of B vitamins and probiotics may have a higher efficacy than using them alone.

Quantification of nine bufadienolides of Shexiang Tongxin Dropping Pills in rat plasma and tissues using UPLC-MS/MS and its application to healthy and ischemia-reperfusion rats pharmacokinetic studies. J Pharm Biomed Anal 2024; 238:115852.

Abstract
Shexiang Tongxin Dropping Pill (STDP) is a well-known compound preparation used in traditional Chinese medicine for treating cardiovascular diseases. Bufadienolides are the major active compounds of toad venom and are the key to the seven medicinal herbs that comprise STDP. In this study, a reliable and sensitive high-performance liquid chromatography-tandem mass spectrometry method was developed and validated for the quantitative determination of nine bufadienolides (bufalin, gamabufotalin, resibufogenin, marinobufagin, arenobufagin, desacetylcinobufagin, telocinobufagin, hellebrigenin, and hellebrigenol) in rat plasma and tissues (heart and liver). The chromatography column used was a Waters ACQUITY UPLC HSS-T3 column with gradient elution using mobile phase consisting of acetonitrile-water (0.1% formic acid added) at a flow rate of 0.25 mL/min. This method passed the methodological validation of plasma and tissues and was successfully applied to pharmacokinetic and tissue distribution studies after oral administration of STDP in healthy and ischemia-reperfusion (I/R) rats. This indicated that most bufadienolides were well absorbed and quickly distributed in the heart and liver. The area-under-the-curve (AUC)(0-t) of most analytes increased in a dose-dependent manner. Moreover, most of the tested components showed lower plasma and higher tissue concentrations in I/R rats than in healthy rats. The above results on the oral pharmacokinetics and tissue distribution may be helpful for the clinical application of STDP.

Simultaneous quantification of seven B vitamins in human faeces by stable isotope label-based high-performance liquid chromatography-tandem mass spectrometry. J Pharm Biomed Anal 2024; 237:115784. [PMID: 37839265 DOI: 10.1016/j.jpba.2023.115784] [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: 08/07/2023] [Revised: 09/27/2023] [Accepted: 10/09/2023] [Indexed: 10/17/2023]
Abstract
B vitamins in the human distal gut are primarily derived from the gut microbiota because daily dietary vitamins are fully absorbed in the small intestine under normal dietary and physiological conditions. Quantitative determination of B vitamins in the distal gut and faecal samples is crucial for understanding the intricate relationship between gut B vitamins, gut microbiota, and host health. In this study, we developed a rapid, robust, and reliable method with a simple extraction procedure for the simultaneous analysis of seven B vitamins in human faeces using high-performance liquid chromatography-electrospray ionisation-tandem mass spectrometry (HPLC-ESI-MS/MS) with stable isotope-labelled internal standards. A protein precipitation approach using methanol as the precipitant was employed to extract vitamin B from human faecal samples. Seven B vitamins were adequately separated and quantified within 9 min by HPLC-ESI-MS/MS with a Pursuit PFP column (2.0 ×150 mm, 3.0 µm), including vitamins B1, B2, B3, B5, pyridoxic acid, pyridoxine, and B7. The lower limits of quantification were within the range of 0.1-25 ng mL-1. The intra-day and inter-day precision and accuracy were both within 15 %. The validated method was successfully applied to 55 faecal samples collected from healthy individuals, patients with type 2 diabetes, and obese patients. Compared with healthy controls, obese patients had lower faecal concentrations of vitamins B1 and B3 and pyridoxic acid, whereas patients with type 2 diabetes had lower faecal concentrations of vitamins B1 and B5.

Pralatrexate inhibited the replication of varicella zoster virus and vesicular stomatitis virus: An old dog with new tricks. Antiviral Res 2024; 221:105787.

Abstract
Varicella zoster virus (VZV) is associated with herpes zoster (HZ) or herpes zoster ophthalmicus (HZO). All antiviral agents currently licensed for the management of VZV replication via modulating different mechanisms, and the resistance is on the rise. There is a need to develop new antiviral agents with distinct mechanisms of action and adequate safety profiles. Pralatrexate (PDX) is a fourth-generation anti-folate agent with an inhibitory activity on folate (FA) metabolism and has been used as an anti-tumor drug. We observed that PDX possessed potent inhibitory activity against VZV infection. In this study, we reported the antiviral effects and the underlying mechanism of PDX against VZV infection. The results showed that PDX not only inhibited VZV replication in vitro and in mice corneal tissues but also reduced the inflammatory response and apoptosis induced by viral infection. Furthermore, PDX treatment showed a similar anti-VSV inhibitory effect in both in vitro and in vivo models. Mechanistically, PDX inhibited viral replication by interrupting the substrate supply for de novo purine and thymidine synthesis. In conclusion, this study discovered the potent antiviral activity of PDX with a novel mechanism and presented a new strategy for VZV treatment that targets a cellular metabolic mechanism essential for viral replication. The present study provided a new insight into the development of broad-spectrum antiviral agents.
