Martin Powell (BSc.(Hons), Dip.Ac, Dip.CHM, MRCHM), reveals the benefit of the Gandoderma Iucidum mushroom for the treatment of TH2 conditions. Allergies and asthma are two examples of histamine- mediated allergic responses. Both conditions are increasing in frequency and are difficult to target with modern medicine. The modern approach to drug research is target-specific and does […]

Abstract Dengue virus (DENV) infection causes serious health problems in humans for which no drug is currently available. Recently, DENV NS2B-NS3 protease has been proposed as a primary target for anti-dengue drug discovery due to its important role in new virus particle formation by conducting DENV polyprotein cleavage. Triterpenoids from the medicinal fungus Ganoderma lucidum have been […]

Abstract Ergosterol peroxide is a natural compound of the steroid family found in many fungi, and it possesses antioxidant, anti-inflammatory, anticancer and antiviral activities. The anti-obesity activity of several edible and medicinal mushrooms has been reported, but the effect of mushroom-derived ergosterol peroxide on obesity has not been studied. Therefore, we analyzed the effect of […]

Abstract The inhibition of viral protease is an important target in antiviral drug discovery and development. To date, protease inhibitor drugs, especially HIV-1 protease inhibitors, have been available for human clinical use in the treatment of coronaviruses. However, these drugs can have adverse side effects and they can become ineffective due to eventual drug resistance. […]

Abstract G. lucidum has a long history of thousands of years in China and is closely related with the lives of the Chinese people. It is reported to cure various diseases due to its high nutritional value and wide range of uses. The fascinating effects of G. lucidum have tethered a multitude of efforts to […]

Abstract Recently a series of triterpenoids were isolated from ganoderma spores and have drawn the attention of chemists and pharmacists. The aim of this review is to summarize the triterpenoids and their bioactivities of ganoderma spores. The chemical and biological literatures of ganoderma spores dealing with the structural analysis and bioactivity assay were selected. Triterpenoids […]

Abstract Two new lanostane-type triterpenes, lucidumol A and ganoderic acid beta, were isolated from the spores of Ganoderma (G.) lucidum, together with a new natural one and seven that were known. The structures of the new triterpenes were determined as (24S)-24,25-dihydroxylanost-8-ene-3,7-dione and 3 beta,7 beta-dihydroxy-11,15-dioxolanosta-8,24(E)-dien-26-oic acid, respectively, by chemical and spectroscopic means. The quantitative analyses […]

Abstract A new lanostane-type terpenoid, lucidenic acid SP1 (1), was isolated from a CHCl(3)-soluble fraction of Ganoderma lucidum spores together with four other known compounds (2 – 5). The structure of lucidenic acid SP1 was determined to be 3 beta,7 beta-dihydroxy-4,4,14 alpha-trimethyl-11,15-dioxo-5 alpha-chol-8-en-24-oic acid by spectroscopic means including 2D-NMR. Twelve triterpenes (1-12) isolated from G. […]

Abstract Our previous studies demonstrated that Ganoderma lucidum polysaccharides (Gl-PS) exhibit potent immunomodulating effects. Immunomodulation plays an important role in hematopoiesis. To investigate the possible mechanism by which Gl-PS promote myelopoiesis during myelosuppression induced by cyclophosphamide, mice were injected intraperitoneally (i.p.) once daily with 2.5 mg/kg of Gl-PS for 10 days and were treated i.p.
