Safety, tolerability and pharmacokinetics of forsythin in healthy subjects: a double-blinded, placebo-controlled single-dose and multiple-dose escalation and food effect study. Ann Med 2023; 55:2274512. [PMID: 37980573 PMCID: PMC10836277 DOI: 10.1080/07853890.2023.2274512] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/18/2023] [Accepted: 10/18/2023] [Indexed: 11/21/2023] Open
Abstract
BACKGROUND Forsythin, an active compound from Forsythiae Fructus, has the potential to treat the common cold and influenza through its antipyretic-analgesic, anti-inflammatory and antiviral effects. The safety, tolerability and pharmacokinetic (PK) profile of forsythin were evaluated in healthy Chinese subjects. METHODS This phase 1a study included three parts: double-blind, randomized, placebo-controlled single-ascending-dose (SAD) (50, 100, 200, 400, 600 or 800 mg), food effect investigation (100 mg) and multiple-ascending-dose (MAD) (50, 100 or 200 mg TID for 5 days). RESULTS Forsythin is safe and tolerable in healthy Chinese subjects. The rates of adverse events (AEs) in the forsythin cohort were similar to those in the placebo cohort. Forsythin is well-absorbed after single or multiple doses and is extensively metabolized. The primary metabolites were aglycone M1, M1 sulphate (M2) and M1 glucuronide (M7). Exposure to forsythin (100 mg) was higher after food intake by approximately 1.4-fold, whereas M2 and M7 did not change. The steady state was reached around three days in the MAD study. Forsythin, M2 and M7 accumulation on day 5 was 1, 3 and 2, respectively. CONCLUSIONS The safety and PK profiles of forsythin support further evaluation of its efficacy in individuals with the common cold or influenza.

The Sesquiterpene Lactone-Rich Fraction of Inula helenium L. Enhances the Antitumor Effect of Anti-PD-1 Antibody in Colorectal Cancer: Integrative Phytochemical, Transcriptomic, and Experimental Analyses. Cancers (Basel) 2023; 15:cancers15030653. [PMID: 36765611 PMCID: PMC9913754 DOI: 10.3390/cancers15030653] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/15/2022] [Revised: 01/13/2023] [Accepted: 01/17/2023] [Indexed: 01/24/2023] Open
Abstract
Treatment strategies combining immune checkpoint inhibitors with sesquiterpene lactones have attracted much attention as a promising approach for cancer treatment. We systemically analyzed gene expression profiles of cells in response to two major sesquiterpene lactones, alantolactone and isoalantolactone, and determined whether the sesquiterpene lactone-rich fraction of Inula helenium L. (SFIH) enhances the antitumor effect of anti-PD-1 antibody in MC38 colorectal cancer-bearing mice. Gene expression and pathway analysis using RNA sequencing data were used to identify the SFIH-driven combined activity with anti-PD-1 antibody. The results showed that SFIH significantly enhanced the antitumor effect of anti-PD-1 antibody by reducing tumor growth and increasing the survival time of mice. Specifically, SFIH exhibited antitumor activity when combined with anti-PD-1 antibody, and the effects were further enhanced compared with monotherapy. An analysis of immune cells indicated that combination treatment with SFIH and anti-PD-1 antibody significantly increased the proportion of CD8+ T cells. Moreover, combination treatment enhanced antitumor immunity by decreasing the population of myeloid-derived suppressor cells and increasing the number of M1-like macrophages. Pathway enrichment analysis revealed that combination therapy activated immune-related pathways to a greater extent than monotherapy. In conclusion, our integrative analysis demonstrates that SFIH enhances the response of murine tumors to anti-PD-1 antibody. These findings provide insight into developing integrative therapeutics and molecular data for the use of natural products as an adjunct treatment for colorectal cancer.

Abstract
Cardiac hypertrophy (CH) is the main compensatory response to chronic heart stress and often progresses to a decompensation state potentially leading to heart failure. Phillyrin (PHI) is a novel compound derived from Forsythia, which has shown anti-inflammatory and anti-virus activities as well as renal protective effects on diabetic nephropathy. Therefore, we investigated the effects of PHI on CH induced by isoproterenol (ISO). Cardiac hypertrophy was induced by ISO in vivo, and the H9C2 cells were treated with ISO. PHI treatment alleviated CH in isoproterenol-induced mice in 7 and 14 days. Echocardiography showed that the PHI improved ISO-induced CH heart function and structure. PHI significantly decreased heart weight/body weight (HW/BW) and heart weight/tibia length (HW/TL) ratios and improved left ventricular (LV) function in ISO-treated mice. Hematoxylin and eosin staining revealed cardiomyocyte areas of the ISO group were significantly increased, and PHI was significantly reduced at 7 and 14 days, PHI-100 groups showed significantly better improvements than PHI-50. Sirius red staining indicated PHI significantly decreased collagen deposition in heart cross-sections induced by ISO, and PHI repressed ISO-induced cTn-I and NT-proBNP expression in mouse serum. In vitro data from H9C2 cells showed that PHI decreased cell areas and total cell protein levels in cells induced by ISO, whereas ANP, BNP, IL-6, and IL-1β expression was significantly inhibited by PHI. Also, PHI simultaneously inhibited P65 and P38 phosphorylation in vivo and in vitro. In conclusion, this study demonstrated the protective effect of PHI on CH in in vivo and in vitro, and this effect was related to the suppression of inflammation through the activation of the P38/NF-κB pathway.

A Unified Model of Age-Related Cardiovascular Disease. BIOLOGY 2022; 11:biology11121768. [PMID: 36552277 PMCID: PMC9775230 DOI: 10.3390/biology11121768] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 10/27/2022] [Revised: 11/18/2022] [Accepted: 11/27/2022] [Indexed: 12/12/2022]
Abstract
Despite progress in biomedical technologies, cardiovascular disease remains the main cause of mortality. This is at least in part because current clinical interventions do not adequately take into account aging as a driver and are hence aimed at suboptimal targets. To achieve progress, consideration needs to be given to the role of cell aging in disease pathogenesis. We propose a model unifying the fundamental processes underlying most age-associated cardiovascular pathologies. According to this model, cell aging, leading to cell senescence, is responsible for tissue changes leading to age-related cardiovascular disease. This process, occurring due to telomerase inactivation and telomere attrition, affects all components of the cardiovascular system, including cardiomyocytes, vascular endothelial cells, smooth muscle cells, cardiac fibroblasts, and immune cells. The unified model offers insights into the relationship between upstream risk factors and downstream clinical outcomes and explains why interventions aimed at either of these components have limited success. Potential therapeutic approaches are considered based on this model. Because telomerase activity can prevent and reverse cell senescence, telomerase gene therapy is discussed as a promising intervention. Telomerase gene therapy and similar systems interventions based on the unified model are expected to be transformational in cardiovascular medicine.

Downregulating PDPK1 and taking phillyrin as PDPK1-targeting drug protect hepatocytes from alcoholic steatohepatitis by promoting autophagy. Cell Death Dis 2022; 13:991. [PMID: 36418288 PMCID: PMC9684571 DOI: 10.1038/s41419-022-05422-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/22/2022] [Revised: 11/04/2022] [Accepted: 11/08/2022] [Indexed: 11/27/2022]
Abstract
The health risk stemming from drinking alcohol is serious, sometimes even life-threatening. Alcoholic steatohepatitis (ASH) is a critical stage leading to cirrhosis and end-stage liver disease. However, its pathogenesis is still far from clearly understood, and a treatment that is widely recognised as effective has not been discovered. Interestingly, PDPK1,3-phosphoinositide-dependent protein kinase 1, also known as PDK1, was observed to be obviously increased in the ASH model by our researchers. We also investigated the protective role of autophagy in ASH. Here, we studied the function of PDPK1 and found an efficient treatment to alleviate symptoms by targeting PDPK1 in ASH. In our study, PDPK1 affected hepatocyte self-healing by inhibiting autophagy. Both inhibiting PDPK1 and the phosphorylation of PDPK1 (ser241) could protect hepatocytes from suffering heavy alcoholic hepatitis.

The neuroprotective effect of phillyrin in intracerebral hemorrhagic mice is produced by activation of the Nrf2 signaling pathway. Eur J Pharmacol 2021; 909:174439.

Abstract
Phillyrin, a natural plant extract, has significant antioxidant and anti-apoptotic effects. However, its effect on intracerebral hemorrhage (ICH) remains unclear. In this study, we investigated a potential role for phillyrin in the regulation of the oxidative stress and apoptosis induced by ICH. A model of ICH was induced by collagenase IV (0.2 U in 1 μl sterile normal saline) in male C57BL/6J (B6) mice and different doses of phillyrin (5, 15, or 30 mg/kg) were intraperitoneally (i.p.) injected at 30 min, 6 h, and 22 h after modeling. We found that phillyrin significantly reduced neural function and lesion volume, improved injury of white and grey matter around the lesion, decreased apoptosis and oxidative stress, increased the expression of nuclear factor-erythroid 2-related factor 2 (Nrf2), heme oxygenase 1(HO-1), NADPH quinone oxidoreductase 1 (NQO1) and Superoxide Dismutase-1(SOD-1) in vitro and in vivo, and protected neurons from the stimulation of hemin by promoting Nrf2 nuclear translocation. Treatment with ML385 (Nrf2 inhibitor) completely reversed the protective effects of phillyrin in vivo after ICH injury. Based on our findings, we conclude that phillyrin treatment alleviates ICH injury-induced apoptosis and oxidative stress via activation of the Nrf2 signaling pathway, highlighting a potential role for phillyrin as an ICH therapeutic.

Study on Medication Rules of Traditional Chinese Medicine against Antineoplastic Drug-Induced Cardiotoxicity Based on Network Pharmacology and Data Mining. EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE 2020; 2020:7498525. [PMID: 33281914 PMCID: PMC7688357 DOI: 10.1155/2020/7498525] [Citation(s) in RCA: 13] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 05/20/2020] [Revised: 08/16/2020] [Accepted: 10/21/2020] [Indexed: 12/12/2022]
Abstract
Methods The targets of antineoplastic drugs with cardiotoxicity were obtained from the National Center for Biotechnology Information (NCBI) database, China national knowledge infrastructure (CNKI) database, and Swiss Target Prediction platform. Then, the cardiotoxicity-related targets were derived from the Gene Cards, Disgenet, OMIM, and DrugBank databases, as well as the drug of current clinical guidelines. The targets both in these two sets were regarded as potential targets to alleviate ADIC. Then, candidate compounds and herbs were matched via Traditional Chinese Medicine Systems Pharmacology (TCMSP) platform. Cytoscape3.7.1 was used to set up the target-compound-herb network. Molecular docking between core targets and compounds was performed with AutodockVina1.1.2. The rules of herbs were summarized by analyzing their property, flavor, and channel tropism. Results Twenty-one potential targets, 332 candidate compounds, and 400 kinds of herbs were obtained. Five core targets including potassium voltage-gated channel subfamily H member 2 (KCNH2), cyclin-dependent kinase 1 (CDK1), matrix metalloproteinase 2 (MMP2), mitogen-activated protein kinase1 (MAPK1), and tumor protein p53 (TP53) and 29 core compounds (beta-sitosterol, quercetin, kaempferol, etc.) were collected. Five core herbs (Yanhusuo, Gouteng, Huangbai, Lianqiao, and Gancao) were identified. Also, the TCM against ADIC were mainly bitter and acrid in taste, warm in property, and distributed to the liver and lung meridians. Conclusion TCM against ADIC has great potential. Our study provides a new method and ideas for clinical applications of integrated Chinese and western medicine in treating ADIC.
