Abstract
Animal venom is an important evolutionary innovation in nature. As one of the most representative animal venoms, scorpion venom contains an extremely diverse set of bioactive peptides. Scorpion venom peptides not only are 'poisons' that immobilize, paralyze, kill, or dissolve preys but also become important candidates for drug development and design. Here, the review focuses on the molecular diversity of scorpion venom peptides, their typical structural characteristics, and their multiple therapeutic or pharmaceutical applications in channelopathies, viral infections and cancers. Especially, the group of scorpion toxin TRPTx targeting transient receptor potential (TRP) channels is systematically summarized and worthy of attention because TRP channels play a crucial role in the regulation of homeostasis and the occurrence of diseases in human. We also further establish the potential relationship between the molecular characteristics and functional applications of scorpion venom peptides to provide a research basis for modern drug development and clinical utilization of scorpion venom resources.

Toxins (Basel) 2023; 15:toxins15050340. [PMID: 37235373 DOI: 10.3390/toxins15050340] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/29/2023] [Revised: 04/28/2023] [Accepted: 04/29/2023] [Indexed: 05/28/2023] Open
Abstract
Thermally processed Buthus martensii Karsch scorpion is an important traditional Chinese medical material that has been widely used to treat various diseases in China for over one thousand years. Our recent work showed that thermally processed Buthus martensii Karsch scorpions contain many degraded peptides; however, the pharmacological activities of these peptides remain to be studied. Here, a new degraded peptide, BmTX4-P1, was identified from processed Buthus martensii Karsch scorpions. Compared with the venom-derived wild-type toxin peptide BmTX4, BmTX4-P1 missed some amino acids at the N-terminal and C-terminal regions, while containing six conserved cysteine residues, which could be used to form disulfide bond-stabilized α-helical and β-sheet motifs. Two methods (chemical synthesis and recombinant expression) were used to obtain the BmTX4-P1 peptide, named sBmTX4-P1 and rBmTX4-P1. Electrophysiological experimental results showed that sBmTX4-P1 and rBmTX4-P1 exhibited similar activities to inhibit the currents of hKv1.2 and hKv1.3 channels. In addition, the experimental electrophysiological results of recombinant mutant peptides of BmTX4-P1 indicated that the two residues of BmTX4-P1 (Lys22 and Tyr31) were the key residues for its potassium channel inhibitory activity. In addition to identifying a new degraded peptide, BmTX4-P1, from traditional Chinese scorpion medicinal material with high inhibitory activities against the hKv1.2 and hKv1.3 channels, this study also provided a useful method to obtain the detailed degraded peptides from processed Buthus martensii Karsch scorpions. Thus, the study laid a solid foundation for further research on the medicinal function of these degraded peptides.

Abstract
Ginsenoside Rh2 is one of the major bioactive ginsenosides in Panax
ginseng. Although Rh2 is known to enhance immune cells activity for
treatment of cancer, its anti-inflammatory and neuroprotective effects have yet
to be determined. In this study, we investigated the effects of Rh2 on spared
nerve injury (SNI)-induced neuropathic pain and elucidated the potential
mechanisms. We found that various doses of Rh2 intrathecal injection
dose-dependently attenuated SNI-induced mechanical allodynia and thermal
hyperalgesia. Rh2 also inhibited microglia and astrocyte activation in the
spinal cord of a murine SNI model. Rh2 treatment inhibited SNI-induced increase
of proinflammatory cytokines, including tumor necrosis factor-α, interleukin
(IL)-1 and IL-6. Expression of miRNA-21, an endogenous ligand of Toll like
receptor (TLR)8 was also decreased. Rh2 treatment blocked the mitogen-activated
protein kinase (MAPK) signaling pathway by inhibiting of phosphorylated
extracellular signal-regulated kinase expression. Finally, intrathecal injection
of TLR8 agonist VTX-2337 reversed the analgesic effect of Rh2. These results
indicated that Rh2 relieved SNI-induced neuropathic pain via inhibiting the
miRNA-21-TLR8-MAPK signaling pathway, thus providing a potential application of
Rh2 in pain therapy.
