Resumen

Nanomedicine has led to the development of new biocompatible and biodegradable materials able to improve the pharmaceutical effect of bioactive components, broadening the options of treatment for several diseases, including cancer. Additionally, some snake venom toxins have been reported to present cytotoxic activity in different tumor cell lines, making them an auspicious option to be used as cancer drugs. The present study aims to evaluate the cytotoxic activity of the northern blacktailed rattlesnake (Crotalus molossus molossus) venomloaded chitosan nanoparticles (Cs-Venom NPs) against the T-47D breast carcinoma cell line. To do so, we first identified the significant proteins composing the venom; afterward, hemocompatibility and cytotoxic activity against tumoral cells were evaluated. The venom was then loaded into chitosan nanoparticles through the ionotropic gelation process, obtaining particles of 415.9±21.67 nm and ζ-potential of +28.3±1.17 mV. The Cs-Venom complex delivered the venom into the breast carcinoma cells, inhibiting their viability and inducing morphological changes in the T-47D cells. These features indicate that these nanoparticles are suitable for the potential use of C. m. molossus venom toxins entrapped within polymer nanoparticles for the future development and research of cancer drugs.
