Scorpion Venom Peptides: From Structural Scaffolds to Therapeutic Applications—A Focus on Antioxidant Mechanisms and Translational Perspectives

  Scorpion Venom Peptides: From Structural Scaffolds to Therapeutic Applications—A Focus on Antioxidant Mechanisms and Translational Perspectives Abstract Scorpion venom peptides, with their stable disulfide backbone, compact structural framework, and highly selective regulation of ion channels, have long been regarded as important molecular probes in neuropharmacology. However, recent studies have revealed their potential for regulating oxidative stress, inflammation, and neuroprotection, making them a new research frontier. In this article, we focus on scorpion venom peptides as drugs, constructing an integrated knowledge framework from structural classification to clinical translation. First, scorpion venom peptides are systematically classified based on cysteine arrangement patterns and three-dimensional folding topology, and their structure–activity relationships are summarized. Based on this, the molecular mechanisms by which scorpion venom peptides regulate ion channels are ...

Description of two new species of the genus Trachelas L. Koch, 1872 and the male of T. gaoligongensis Jin, Yin & Zhang, 2017 from China (Araneae, Trachelidae)

Abstract

Two new spider species of the genus Trachelas L. Koch, 1872 are described from China: Trachelas kavanaughi sp. nov. (♀) and Trachelas ventriosus sp. nov. (♀). The male of Trachelas gaoligongensis Jin, Yin & Zhang, 2017 is described for the first time. Illustrations of the body and copulatory organs and a distribution map are provided.
