Exploring the Phytochemistry, Signaling Pathways, and Mechanisms of Action of Tanacetum parthenium (L.) Sch.Bip.: A Comprehensive Literature Review.

The traditional use of Tanacetum parthenium (L.) Sch.Bip., commonly known as feverfew, extends across various medical conditions, notably those associated with pain and inflammation. In alignment with the growing trend towards developing medications that target specific signaling pathways for enhanced efficacy and reduced side effects, extensive research has been conducted to investigate and validate the pharmacological effects of feverfew. Among its bioactive compounds, parthenolide stands out as the most potent, categorized as a germacranolide-type sesquiterpene lactone, and has been extensively studied in multiple investigations. Significantly, the anti-inflammatory properties of feverfew have been primarily attributed to its capacity to inhibit nuclear factor-kappa B (NF-κB), resulting in a reduction in pro-inflammatory cytokines like tumor necrosis factor-alpha (TNF-α). Furthermore, the anticancer properties of feverfew have been associated with the modulation of Mitogen-Activated Protein Kinase (MAPK) and NF-κB signaling pathways. This study further delves into the neuroprotective potential of feverfew, specifically in the management of conditions such as migraine headaches, epilepsy, and neuropathic pain through various mechanisms. The core objective of this study is to elucidate the phytochemical composition of feverfew, with a particular emphasis on understanding the molecular mechanisms and examining the signaling pathways that contribute to its pharmacological and therapeutic effects. Additionally, the safety, toxicity, and potential adverse effects of feverfew are comprehensively evaluated, with an overarching goal of providing valuable insights into the plant's potential for targeted and effective treatments.

INTRODUCTION: The Paeoniaceae family contains only the Paeonia genus and is considered the major group of flowering plants. Several traditional and pharmacological applications of Paeoniaceae herbs have been described. The current paper aimed to determine the pharmacological activities of the most prevalent herbs from the genus Paeonia by focusing on the underlying mechanism of action and signaling pathways to provide insight for further in-depth research on the medicinal resources of Paeonia. METHOD: The "Paeoniaceae" keyword was searched from 1st January 1995 to 15th May 2024 through the PubMed and Scopus databases. Only papers related to pharmacology, pharmaceutics, and toxicology were extracted. The possible pharmacological activity of the Paeonia plants underlying their mechanism of action and signaling pathways was subsequently discussed. RESULTS: Following our venture, only 15 Paeonia herbs were adequately evaluated for their pharmacological applications. Paeonia lactiflora Pall., Paeonia suffruticosa Andrews, and Paeonia emodi Royle are among the most prevalent Paeonia plants that have attracted increased amounts of attention in modern pharmacological studies. Paeonia herbs possess various pharmacological applications, such as anti-inflammatory, anti-allergic, anticancer, antimicrobial, cardiovascular protective, cosmetic and skincare, radical scavenging, hepatoprotective and anti-ulcerative, anti-diabetic, musculoskeletal, and neuroprotective effects, and can be used as alternative therapies under critical medical conditions. CONCLUSION: Among the applications of Paeonia herbs, anti-inflammatory and antioxidant activities are critical, as most of the other pharmacological effects are attributed to them. In other words, nuclear factor (NF)-κB and nuclear factor erythroid 2-related factor 2 (Nrf2) can be considered the most important signaling pathways involved in the pharmacological activity of Paeonia herbs.

Comparison of intravenous sodium bicarbonate and sodium chloride combination versus intravenous sodium chloride hydration alone in reducing amphotericin B nephrotoxicity: a randomized clinical trial.

BACKGROUND AND PURPOSE: The most important adverse reaction of amphotericin B (AmB) is nephrotoxicity. The aim of this study was to assess the potential effectiveness of intravenous saline + sodium bicarbonate versus intravenous sodium chloride hydration in preventing or attenuating AmB nephrotoxicity. EXPERIMENTAL APPROACH: A randomized, non-placebo-controlled, single-blinded clinical trial was conducted in two adult hematology-oncology wards of Namazi hospital. Eligible patients were randomly assigned into either the normal saline or normal saline + sodium bicarbonate groups by the ratio of 1:2. In the normal saline group, 1000 mL of sodium chloride 0.9% (154 meq sodium) was given intravenously as two equal 500 mL volumes before and during the infusion of AmB. Patients in the saline + sodium bicarbonate group received 500 mL sodium chloride 0.9% (72 meq sodium) before and 500 mL isotonic sodium bicarbonate (72 meq sodium) intravenously during AmB infusion. FINDINGS/RESULTS: The rate of AmB nephrotoxicity was comparable between normal saline and sodium bicarbonate groups (54.2% and 41.6%, respectively; P = 0.3). This difference did not reach the level of statistical significance after considering AmB dose and duration of the treatment. The frequency of hypokalemia and hypomagnesemia did not differ significantly between the two groups even after adjusting the results according to AmB dose and treatment duration. CONCLUSION AND IMPLICATIONS: The results of the current preliminary clinical trial suggested that the combination of sodium bicarbonate and normal saline compared to normal saline alone appears to have no superiority in preventing or attenuating different studied aspects of AmB nephrotoxicity in patients with hematological malignancies.
