Indolealkylamines in the venom of the scorpion Thorellius intrepidus. Toxicon 2023; 233:107232. [PMID: 37536653 DOI: 10.1016/j.toxicon.2023.107232] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/30/2023] [Revised: 07/14/2023] [Accepted: 07/30/2023] [Indexed: 08/05/2023]
Abstract
Scorpions are a group of arthropods that strike fear in many people due to their severe medical symptoms, even death, caused by their venomous stings. Even so, not all scorpion species contain harmful venoms against humans but still have valuable bioactive molecules, which could be used in developing new pharmaceutical leads for treating important diseases. This work conducted a comprehensive analysis of the venom from the scorpion Thorellius intrepidus. The venom of T. intrepidus was separated by size exclusion chromatography, and four main fractions were obtained. Fraction IV (FIV) contained small molecules representing over 90% of the total absorbance at 280 nm. Analysis of fraction FIV by RP-HPLC indicated the presence of three main molecules (FIV.1, FIV.2, and FIV.3) with similar UV absorbance spectra profiles. The molecular masses of FIV.1, FIV.2, and FIV.3 were determined, resulting in 175.99, 190.07, and 218.16 Da, respectively. Further confirmation through 1H-NMR and 13C-NMR analyses revealed that these molecules were serotonin, N-methylserotonin, and bufotenidine. These intriguing compounds are speculated to play a pivotal role in self-defense and increasing venom toxicity and could also offer promising biotechnological applications as small bioactive molecules.

J Venom Anim Toxins Incl Trop Dis 2015; 21:43.

Abstract
Hyaluronidases are enzymes that mainly degrade hyaluronan, the major glycosaminoglycan of the interstitial matrix. They are involved in several pathological and physiological activities including fertilization, wound healing, embryogenesis, angiogenesis, diffusion of toxins and drugs, metastasis, pneumonia, sepsis, bacteremia, meningitis, inflammation and allergy, among others. Hyaluronidases are widely distributed in nature and the enzymes from mammalian spermatozoa, lysosomes and animal venoms belong to the subclass EC 3.2.1.35. To date, only five three-dimensional structures for arthropod venom hyaluronidases (Apis mellifera and Vespula vulgaris) were determined. Additionally, there are four molecular models for hyaluronidases from Mesobuthus martensii, Polybia paulista and Tityus serrulatus venoms. These enzymes are employed as adjuvants to increase the absorption and dispersion of other drugs and have been used in various off-label clinical conditions to reduce tissue edema. Moreover, a PEGylated form of a recombinant human hyaluronidase is currently under clinical trials for the treatment of metastatic pancreatic cancer. This review focuses on the arthropod venom hyaluronidases and provides an overview of their biochemical properties, role in the envenoming, structure/activity relationship, and potential medical and biotechnological applications.

Morey SS, Kiran KM, Gadag JR. Purification and properties of hyaluronidase from Palamneus gravimanus (Indian black scorpion) venom. Toxicon 2006; 47:188-95.

Abstract
Scorpion venoms are a rich source of enzymes. Some of the enzymes such as phospholipase A2, proteolytic enzymes and phosphodiesterase are well characterized. However, hyaluronidase has not been studied extensively. In this paper we describe the purification and characterization of hyaluronidase (Hyaluronate lyase, E.C.3.2.1.35) from the Palamneus gravimanus scorpion venom by a combination of gel filtration on Sephadex G-75 and ion-exchange chromatography on DEAE-cellulose. The optimal pH and temperature for its maximum activity of the isolated enzyme were 4.5 and 37 degrees C, respectively, and its K(m) was 47.61 microg/ml at 37 degrees C and its specific activity was 6411.7 +/- 117TRU/min per mg against 250 +/- 4.0 TRU/min per mg for the whole desiccated venom suggesting 25-fold purification. The molecular weight of the isolated enzyme was 52 +/- 1 kDa as estimated by sodium dodecyl sulfate-polyacrylamide gel electrophoresis and gel filtration chromatography on Sephadex G-75. The enzyme was stable for 30 days in the presence of NaCl; no loss of activity was observed up to 37 degrees degrees C and showed a sharp decrease in its activity at 40 degrees C. Heparin inhibited the enzyme activity.

Abstract
Enzymes with gelatinolytic activity were detected in Tityus bahiensis and Tityus serrulatus venom. Their activity was optimal at pH 8.0 in SDS-PAGE-gelatin. They were inhibited by PMSF but not by iodoacetamide, pepstatin or phenantrolin in the assay conditions used. This suggests that these enzymes are serine proteases. The presence of metal ions did not affect the proteolytic activity of these enzymes. Several possible functions may be envisaged for these enzymes: in tissue permeabilization, pancreatitis and toxin processing.

Abstract
The hyaluronidase activities of venoms of snakes indigenous to Southeast Asia were investigated. With the exception of the venom of the Malayan krait Bungarus candidus, the elapid venoms had either little or no hyaluronidase activities, whereas the viperid venoms possessed considerable activity. A component of Russell's viper venom with hyaluronidase activities had a mol. wt of approximately 14,000. Neither MP4, a monoclonal antibody raised against the purified Russell's viper venom hyaluronidase toxin, nor a monospecific polyclonal antivenom neutralized the hyaluronidase activities of this purified hyaluronidase component of crude Russell's viper venom. The Russell's viper venom hyaluronidase activities was labile on heating and storage. The significance of these observations to envenomation and antivenom production is discussed.
