3. Kuniyoshi Shimizu, Ganoderma Triterpenoids: Hint for Understanding Multi-Medicinal effects of Ganoderma mushroom, International Congress of SOCIETY FOR ETHNOPHARMACOLOGY, INDIA 2022, 2022.04, Lingzhi (in Chinese) or Reishi (in Japanese), recently identified as Ganoderma lingzhi which is different from Ganoderma lucidum originally described from Europe, has been treasured for its medicinal value in traditional medicine in Japan, China and Korea for thousands of year. Of all Ganoderma mushrooms, which account for more than 300 known triterpenoids, G. lingzhi has been the most well-studied species. G. lingzhi was reported with a wide range of bioactivities including antioxidative, anti-aging, immunomodulatory activity, anti-hepatotoxic, ant-angiogenic, anti-histaminic, potential anticancer activity and even anti-HIV. Our group has isolated many triterpenoids from reishi and reported their bioactivities, including inhibition of benign prostatic hypertrophy, anti-androgenic osteoclastogenesis, anti-diabetes, anti-diabetic complication, antihypertension, inhibition of neuraminidase and anti-cancer activities. Following topics will be discussed.
1) Mushroom sample and triterpenoids isolation
2) 5-reductase inhibition and anti-benign prostate hyperplasia
3) Inhibition of osteoclast differentiation (anti-osteoporosis)
4) Inhibition of α-glucosidase (anti-diabetes)
5) Inhibition of aldose reductase (anti-diabetic complication)
6) Inhibition of angiotensin-converting enzyme (anti-hypertension)
7) Inhibition of neuraminidase (anti-influenza)
8) Inhibition of Rho kinase
9) Tumor cell cytotoxicity (anti-cancer)
10) Clues to pharmacological mechanisms (identification of target protein)
11) LC-MS/MS analysis for evaluating functional-quality of Ganoderma mushroom

Up to now, more than 300 triterpenoids have been reported from Ganoderma mushroom, especially from G. lingzhi. Also, many bioactivities of these compounds have been investigated. Potential application of this mushroom and the compounds in it on three indications including cancer, diabetes, and immune stimulation was also thoroughly examined. However, future randomized controlled clinical trials are still necessary. Despite of lacking of enough evidence from clinical trials, this mushroom remains a popular agent in commercial products. From this fact, studies on the Ganoderma mushroom should be still a hotter topic in the near futures.

Isolation, Characterization and in Vitro Antioxidant Activity of Polysaccharide from Pholiota adiposa, 第70回日本木材学会, 2020.03, Pholiota adiposa is a species of edible fungus in the family Strophariaceae. It is a valuable mushroom that is grown only in Fukuoka. Polysaccharides extracted from P. adiposa were reported to have immune-stimulatory and antitumor properties, as well as hypolipidemic effect, anti-oxidant and anti-aging activities. We decide to conduct a more systematically studies of P. adiposa Polysaccharide (PAP), including the extraction, isolation, purification, characterization and in vitro antioxidant activity of purified polysaccharide. Crude polysaccharide of P. adiposa was extracted by hot water extraction and alcohol precipitation, and deproteinized by Sevag method. The crude polysaccharide of P. adiposa was further purified using Diethylaminoethanol (DEAE) Sepharose FF and Sephacryl S-200 HR column chromatography. After UV-visible spectrophotometry and gel permeation chromatography (GPC) analysis, the separated polysaccharide was determined to be a purified polysaccharide of 95% and 99% purity. The molecular weight was determined using pullulan standards (molecular weight T-736, 348, 200, 113, 48.8, 23.0, 9.9, 6.6 KD) and the monosaccharide composition was analyzed by HPLC-ELSD. The isolates were analyzed by Fourier Transform Infrared Spectroscopy (FT-IR), Nuclear Magnetic Resonance(NMR) for structural analysis. Then, the antioxidant ability of the polysaccharide fractions was evaluated by the ORAC method and the DPPH method. .

YHIYA Amen,AHMED Ashour,ROGERS Mwakalukwa,NAOMICHI Takemoto,MASUMI Nagae,KENSHIN Hiromatsu,KOICHIRO Ohnuki,KUNIYOSHI Shimizu, Anti-Hyperglycemic Effect of Pholiota adiposa on Human Subjects and isolation of active components, 第70回日本木材学会, 2020.03, Mushrooms are known to possess bioactive compounds responsible for anti-hyperglycemic effect. An in vitro α-glucosidase inhibition assay of 8 different mushroom species, resulted in the recognition of the methanolic extract of Pholiota adiposa as the strongest inhibitor. A randomized placebo controlled clinical trials performed in 15 healthy Japanese adults, showed significant dose dependent decrease in the blood glucose level, after consumption of 25 g and 50 g fresh equivalent of P. adiposa. Deep investigation of the methanolic extract of P. adipose, guided by an in vitro α-glucosidase inhibitory assay was performed for isolation of the active components. The n-hexane-soluble fraction of the methanolic extract was found active and lipids-like constituents of this fraction were found to be responsible for the activity of the extract. These results will be valuable in establishing P. adiposa as an important source of bioactive compounds capable of suppressing postprandial hyperglycemia in patients with Type 2 diabetes..
34. MWAKALUKWA Rogers,AMEN Yhiya,SHIMIZU Kuniyoshi, Postprandial hyperglycemia lowering effect of metabolites isolated from olive mill wastes (OMW)―An inhibitory activity on α-glucosidase and α-amylase enzymes―, 第70回日本木材学会, 2020.03, Diabetes is characterized by chronic hyperglycemia resulting from either, when the pancreas does not produce enough insulin (type 1), or when the body cannot effectively use the insulin it produces (type 2). The raise of blood glucose level, postprandially, results from hydrolysis of carbohydrates catalyzed by α-glucosidase and α-amylase. Thus, inhibition of these enzymes results into massive reduction of postprandial blood glucose levels ? a major cause of diabetes. In the present study, we report the isolation and anti-diabetic activity (inhibitory effect on α-glucosidase and α-lipase) of eight (8) compounds, one of them being novel, from olive mill wastes (OMW). Additionally, we investigated the enzyme kinetic analysis of the most active compounds to assist the possible characterization of the inhibition mechanisms involved. We observed that four compounds, 1, 2, 4 and 7, had higher activity against both enzymes. The kinetics studies of these compounds revealed that oleanolic acid 1 and luteolin-7-O-glucoside 7 inhibit α-glucosidase in a mixed-type fashion, while 1-acetoxypinoresinol 4 does it uncompetitively. Both mixed type and uncompetitive inhibition are similar to noncompetitive inhibition except that binding of the substrate or the inhibitor affect the enzyme’s binding affinity for the other. Thus for both, mixed type and uncompetitive, Ki value, which measures the affinity of the inhibitor for an enzyme was greater than 1 (Ki >1). Even though the novel compound, 3,4-dihydroxyphenyl-2-ethoxyethanol 5 exhibited poor activity, it helped to study the SAR for compounds of same class (hydroxytyrosol acetate 6 and hydroxytyrosol), whereby we clearly observed that both methoxylation and esterification of different positions does not influence their activity against the enzymes. This work attracts more attention to OMW as a potential source of lead compounds for structural modification to improve and develop new anti-diabetic drugs..
