    Characterization of Leiurus abdullahbayrami (Scorpiones: Buthidae) venom: peptide profile, cytotoxicity and antimicrobial activity
    (Biomed Central Ltd, 2014) Erdes, Efe; Dogan, Tugba Somay; Cosar, Ilhan; Danisman, Tarik; Kunt, Kadir Bogac; Seker, Tamay; Ozen, Can
    Background: Scorpion venoms are rich bioactive peptide libraries that offer promising molecules that may lead to the discovery and development of new drugs. Leiurus abdullahbayrami produces one of the most potent venoms among Turkish scorpions that provokes severe symptoms in envenomated victims. Methods: In the present study, the peptide profile of the venom was investigated by electrophoretic methods, size-exclusion and reversed-phase chromatography and mass spectroscopy. Cytotoxic and antimicrobial effects were evaluated on a breast cancer cell line (MCF-7) and various bacterial and fungal species. Results: Proteins make up approximately half of the dry weight of L. abdullahbayrami crude venom. Microfluidic capillary electrophoresis indicated the presence of 6 to 7 kDa peptides and proved to be a highly practical peptidomics tool with better resolution when compared to conventional polyacrylamide gel electrophoresis. Mass spectroscopy analysis helped us to identify 45 unique peptide masses between 1 to 7 kDa with a bimodal mass distribution peaking between molecular weights of 1 to 2 kDa (29%) and 3 to 4 kDa (31%). L. abdullahbayrami crude venom had a proliferative effect on MCF-7 cells, which may be explained by the high concentration of polyamines as well as potassium and calcium ions in the arachnid venoms. Antimicrobial effect was stronger on gram-negative bacteria. Conclusions: This work represents the first peptidomic characterization of L. abdullahbayrami venom. Considering the molecular weight-function relationship of previously identified venom peptides, future bioactivity studies may lead to the discovery of novel potassium and chloride ion channel inhibitors as well as new antimicrobial peptides from L. abdullahbayrami venom.

    Two new species belonging to Coreodrassus and Poecilochroa (Aranei: Gnaphosidae) from Anatolia with comments on taxonomy of both genera
    (Kmk Scientific Press Ltd, Moscow State Univ, 2024) Cosar, Ilhan; Danisman, Tarik; Marusik, Yuri M.
    Two new species are described from Anatolia: Coreodrassus recepsahini sp.n. (male female) and Poecilochroa ilkerakkusi sp.n. (male). Coreodrassus recepsahini sp.n. differs from the sibling C. semidesertus Ponomarev et Tsvetkov, 2006 (re-illustrated here) by the shape of copulatory organs. Poecilochroa ilkerakkusi sp.n. well differs from P. hamipalpis (Kroneberg, 1875) by contrast leg colouration. Coreodrassus Paik, 1892 is split in two species groups and diagnoses are provided. Poecilochroa Westring, 1874 species known from males are also split in two groups, of which the senilis-group may represent a separate genus. The type locality of the new species of Coreodrassus represents the westernmost record of the genus in the entire range. Coreodrassus boldgivi Jargalsaikhan, Fomichev et Nergui, 2023 syn.n. from Mongolia was found to be a junior synonym of C. murphyi Liu et Zhang, 2023. All distribution records of Coreodrassus species are mapped. The northernmost distribution limits of two genera are briefly discussed as well as Gnaphosidae species endemic and subendemic to Turkey.
