Snake venom toxins in cancer therapy: advances in targeted delivery and peptide design

  Snake venom toxins in cancer therapy: advances in targeted delivery and peptide design Abstract Snake venom represents a potent biological arsenal of cytotoxic compounds. Venom proteins and peptides, including disintegrins, venomous enzymes, three-finger toxins, and serine proteases, have garnered attention as effective anticancer agents. Despite their efficacy at nano- or micromolar concentrations, non-standardized mixtures often limit their therapeutic utilization, necessitating fractionation to minimize side effects. This review examines the antitumor potential of snake venom and its constituent proteins and peptides through a literature search in NCBI PubMed. We highlight the antitumor efficacies of venom polypeptides by correlating them with IC 50 values across various cell lines, demonstrating micromolar cytotoxic concentrations. The review encompasses several key areas: whole venom antitumor efficacy, mechanisms of action of individual proteins and peptides, fractionation...

Country roads, take me home: Cyclocosmia johndenveri, a new species of trapdoor spider from the mountains of West Virginia (Araneae: Halonoproctidae)

Abstract
A new species of the enigmatic trapdoor spider genus Cyclocosmia Ausserer, 1871 is described from West Virginia, United States of America. Cyclocosmia johndenveri sp. nov. represents a significant northeasterly range extension for the genus and is described based on the male.
