Abstract
One distinguishing feature of the persimmon, that differentiates it from other fruits, is its high proanthocyanidins content, known as persimmon tannin (PT). Despite the poor absorption of PT in the small intestine, results from animal studies demonstrate that PT has many health benefits. Our goal in this review is to summarize the literature that elucidates the relationship between PT structure and activity. In addition, we also summarize the potential mechanisms underlying the health benefits that result from PT consumption; this includes the hypolipidemic, hypoglycemic, antioxidant, anti-inflammatory, antiradiation, antibacterial and antiviral, detoxification effects on snake venom, and the absorption of heavy metals and dyes. Studies show that PT is a structurally distinct proanthocyanidins that exhibits a high degree of polymerization. It is galloylation-rich and possesses unique A-type interflavan linkages in addition to the more common B-type interflavan bonds. Thus, PT is converted into oligomeric proanthocyanidins by depolymerization strategies, including the nucleophilic substitution reaction, acid hydrolysis, and hydrogenolysis. In addition, multiple health benefits exerted by PT mainly involve the inactivation of lipogenic and intracellular inflammatory signaling pathways, activation of the fatty acid oxidation signaling pathway, regulation of gut microbiota, and highly absorptive properties.

Evaluation of Protection by Caffeic Acid, Chlorogenic Acid, Quercetin and Tannic Acid against the In Vitro Neurotoxicity and In Vivo Lethality of Crotalus durissus terrificus (South American Rattlesnake) Venom. Toxins (Basel) 2021; 13:toxins13110801. [PMID: 34822584 PMCID: PMC8623703 DOI: 10.3390/toxins13110801] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/31/2021] [Revised: 11/03/2021] [Accepted: 11/10/2021] [Indexed: 11/17/2022] Open
Abstract
Systemic envenomation by Crotalus durissus terrificus (South American rattlesnake) can cause coagulopathy, rabdomyolysis, acute kidney injury, and peripheral neuromuscular blockade, the latter resulting in flaccid paralysis. Previous studies have shown that plant products such as tannic acid and theaflavin can protect against the neuromuscular blockade caused by C. d. terrificus venom in vitro. In this work, we used mouse-isolated phrenic nerve-diaphragm preparations to examine the ability of caffeic acid, chlorogenic acid, and quercetin to protect against C. d. terrificus venom-induced neuromuscular blockade in vitro. In addition, the ability of tannic acid to protect against the systemic effects of severe envenomation was assessed in rats. Preincubation of venom with caffeic acid (0.5 mg/mL), chlorogenic acid (1 mg/mL), or quercetin (0.5 mg/mL) failed to protect against venom (10 μg/mL)-induced neuromuscular blockade. In rats, venom (6 mg kg−1, i.p.) caused death in ~8 h, which was prevented by preincubation of venom with tannic acid or the administration of antivenom 2 h post-venom, whereas tannic acid given 2 h post-venom prolonged survival (~18.5 h) but did not prevent death. Tannic acid (in preincubation protocols or given 2 h post-venom) had a variable effect on blood creatinine and urea and blood/urine protein levels and prevented venom-induced leukocytosis. Tannic acid attenuated the histological lesions associated with renal damage in a manner similar to antivenom. The protective effect of tannic acid appeared to be mediated by interaction with venom proteins, as assessed by SDS-PAGE. These findings suggest that tannic acid could be a potentially useful ancillary treatment for envenomation by C. d. terrificus.

Persimmon highly galloylated-tannins in vitro mitigated α-amylase and α-glucosidase via statically binding with their catalytic-closed sides and altering their secondary structure elements. J Food Biochem 2020; 44:e13234. [PMID: 32301514 DOI: 10.1111/jfbc.13234] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/30/2019] [Revised: 03/21/2020] [Accepted: 03/25/2020] [Indexed: 12/22/2022]
Abstract
Reticence of α-amylase (α-Amy) and α-glucosidase (α-Glu) is needed due to their mitigation potency on the glucose absorption. In this study, the anti-amylolytic effects of persimmon tannins (PT) on α-Amy and α-Glu and their interaction mechanisms were investigated. It was found that PT inhibited α-Amy and α-Glu with the half inhibitory concentration (IC50 ) values of 0.35 and 0.24 mg/ml, respectively. Fluorescence and FT-IR spectrometry results showed that PT could bind to enzymes and alter their conformations. Molecular docking showed that the structural units of PT interacted with the key sites (amino acids Glu233, Asp197, and Asp300) of α-Amy by H-bonds and π-π interactions, while they bound to the residues closed to the active sites of α-Glu. The whole results implied that PT was a promising mitigator of α-Amy and α-Glu. It might help to understand mechanisms of glycemic response inhibition of PT and develop certain therapeutic strategies against diabetes. PRACTICAL APPLICATIONS: α-Amy and α-Glu are the crucial starch digestive enzymes associated with type II diabetes mellitus in humans. Persimmon is an excellent source of bio-functional tannins which potentially mitigate the type II diabetes. This study showed that PT beneficially decreased the action of the carbohydrate digestion-related enzymes, namely α-Amy and α-Glu via interaction simultaneously, which could be used to formulate a functional food and natural medicine.
