Abstract: Buthus martensii Karsch (BmK) scorpion venom and its extracts are compounds
found to contain a mixture of peptides with antitumor and analgesic activities. The extracts also
contain polypeptides, lipids, nucleotides, mucoproteins, and other unknown substances showing
potential therapeutic application. Finding medically relevant toxins, a range of peptides have
been purified from BmK scorpion venom. These scorpion toxins are believed to modulate pain
pathways to treat pain and cancer. This study aims to review the literature on BmK scorpion
peptides with dual functions, their analgesic effects, and their mechanism of action in pain treatments
and cancer. We reviewed the literature published between 1990 and 2023 from various
databases and identified 68 articles suitable for our narrative review. In 1994, the first BmK
scorpion peptide with an analgesic effect was purified. Since then, more analgesic peptides have
been purified, including BmK AGAP, BmK AGAP-SYPU2, BmK AGP, BmK AGP-SYPU1,
BmK AGP-SYPU2, BmK AS, and BmK iT2. Studies have demonstrated that these peptides bind
to voltage sodium channels and inhibit the inactivation of the activated sodium channels to block
neuron transmission. The analgesic activities of these peptides have been examined on different
pain stimuli, resulting in strong analgesic and antitumor effects. Moreover, the antitumor activities
of these peptides have been investigated in vitro and in vivo. The findings showed that the
analgesic peptides may have antitumor effects. Based on their dual functions, these peptides have
the potential to be developed as practical therapeutic agents for the treatment of cancer-related
pain.
