Abstract:
Background: Higenamine, a bioactive alkaloid derived from plants such as Aconitum and Annona squamosa, has been traditionally used in Chinese medicine for treating heart diseases like bradycardia, arrhythmia, and heart failure. It exhibits multiple pharmacological effects, including anti-oxidative stress, improved cellular energy metabolism, anti-apoptosis, and enhanced erectile dysfunction. Aim and Methods: To investigate the reasons for these functions of higenamine and its application in the clinic, the literature of the database was searched and read in this study. Results: As a non-select

Abstract:
We have investigated the effectiveness of higenamine in the treatment of malignant glioma, and explored its possible mechanism in C6 glioma cells. The efficacy of higenamine on viability of cells, apoptosis, cell cycle arrest, DNA fragmentation, and biochemical markers was examined by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assay, flow cytometry, enzyme-linked immunosorbent assay, and Western blotting. The biochemical markers investigated included the effect of higenamine on the expression of phosphoinositide-3-kinase/protein kinase B, B-cell lymphoma 2, BCL2- associated X

Abstract:
AbstractHigenamine is a natural benzyltetrahydroisoquinoline alkaloid produced by various plants. In the World Anti-Doping Agency report of 2020, higenamine is classified as a class S3 (selective and nonselective β2-agonist) prohibited substance. To minimize the problems resulting from the misuse of higenamine-containing products as well as from the abuse of doping agents in sport, numerous higenamine-detection methods have been investigated. In the present study, a monoclonal antibody against the (S)-enantiomer of higenamine was successfully produced and applied in the indirect competitive EL

Abstract:
Background: Higenamine is a β2 agonist of plant origin. The compound has been included in WADA’s prohibited list since 2017. Higenamine may be detected in different plants and many food supplements of natural origin. Methods: Our literature search was conducted through PubMed, Science Direct, Google Scholar, and Web of Science studies investigating the presence of higenamine in plants that are used in traditional folk medicine or included in food supplements. Our study aimed to assess the risk of adverse analytical findings caused by higenamine-containing plants. Results: Based on our literatu

Abstract:
In this article, we determine the pH effect and chemical mechanism of antioxidant higenamine by using four spectrophotometric assays: (1) 2-phenyl-4,4,5,5-tetramethylimidazoline-1-oxyl-3-oxide radical (PTIO•)-scavenging assay (at pH 4.5, 6.0, and 7.4); (2) Fe3+-reducing power assay; (3) Cu2+-reducing power assay; and (4) 1,1-diphenyl-2-picryl-hydrazyl (DPPH•)-scavenging assay. The DPPH•-scavenging reaction product is further analyzed by ultra-performance liquid chromatography, coupled with electrospray ionization quadrupole time-of-flight tandem mass spectrometry (UPLC-ESI-Q-TOF-MS/MS) technol

Abstract:
Environmental pollutants such as fine dust are increasingly linked to premature skin aging. In this study, we investigated the protective effects of higenamine, a natural plant alkaloid, against fine-dust-induced skin aging in human keratinocytes (HaCaT cells). We found that higenamine significantly attenuated fine-dust-induced expression of matrix metalloproteinase-1 (MMP-1), a key enzyme involved in collagen degradation. Furthermore, higenamine was found to modulate fine-dust-induced AP-1 and NF-κB transactivation, which are crucial factors for MMP-1 transcription. Higenamine also impeded fi

Since 2017, higenamine has been added to the World Anti-Doping Agency (WADA) prohibited list as a β2-agonist prohibited at all times for sportspersons. According to WADA’s report, positive cases of higenamine misuse have been increasing yearly. However, higenamine occurs naturally in the Chinese herb lotus plumule—the green embryo of lotus (Nelumbo nucifera Gaertn) seeds—commercially available as concentrated powder on the Asian market. This study evaluated the major phytochemical components of lotus plumule products using an appropriate extraction method, followed by a human study in which th

Abstract:
Sini decoction is a well-known formula of traditional Chinese medicine, which has been used to treat cardiovascular disease for many years. Previously, we demonstrated that Sini decoction prevented doxorubicin-induced heart failure in vivo. However, its active components are still unclear. Thus, we investigated the active components of Sini decoction and their cardioprotective mechanisms in the in vitro neonatal rat cardiomyocytes and H9c2 cell line models of doxorubicin-induced cytotoxicity. Our results demonstrated that treatment with higenamine or [6]-gingerol increased viability of doxorub

Abstract:
Objective: Higenamine, an herbal agent also known as norcoclaurine, is thought to stimulate β-androgenic receptors and possess lipolytic activity. It is currently making its way into the dietary supplement market. To our knowledge, no studies have been conducted to determine the safety profile of oral higenamine when used alone and in conjunction with other commonly used lipolytic agents. Methods: Forty-eight men were assigned to ingest either a placebo, higenamine, caffeine, or higenamine + caffeine + yohimbe bark extract daily for a period of 8 weeks.
