Abstract
Context: Colorectal cancer (CRC) remains a significant global health challenge despite advances in treatment modalities. The coelomic fluid of Lytechinus variegatus emerges as a rich source of bioactive peptides with the potential as a new therapeutic anticancer agent.
Aims: To analyze the toxicity, allergenicity, and potential of L. variegatus coelomic fluid peptides as multitarget inhibitor agents of CRC cancer cells through an in silico study.
Methods: Ten peptides from L. variegatus coelomic fluid were processed using UCSF Chimera software to model the three-dimensional structure. ToxinPred and AllerTop web servers were used to analyze the toxicity and allergenicity of peptides, respectively. The 3D structures of EGFR, AKT1, GSK3B, VEGFR2, and JAK3 were retrieved from the PDBJ database. MOE Software was used to perform molecular docking.
Results: Peptide 4 binds to the ATP binding pocket of GSK3B protein with the strongest binding affinity value (-8,68 kcal/mol). The docking results between EGFR and peptides showed that peptide 10 binds to the ATP binding pocket with the lowest binding affinity (-9.52 kcal/mol). Peptide 2 binds to the ATP binding pocket of AKT1 with the lowest binding affinity value (-9.16 kcal/mol). Peptide 3 has the lowest binding affinity value of the JAK3 ATP binding pocket (-8,67 kcal/mol). Peptide 7 binds to the ATP binding pocket of VEGFR2 with the strongest binding affinity (-9,67 kcal/mol).
Conclusions: The L. variegatus peptides have the potential as multitarget anti-CRC agents by inhibiting the activity of GSK3B, EGFR, AKT1, JAK3, and VEGFR2 proteins through the ATP competitive inhibitor action based on in silico study.
Keywords: anticancer; colorectal cancer; Lytechinus variegatus; molecular docking.

Resumen
Contexto: El cáncer colorrectal (CCR) sigue siendo un importante desafío para la salud mundial a pesar de los avances en las modalidades de tratamiento. El líquido celómico de Lytechinus variegatus surge como una rica fuente de péptidos bioactivos con potencial como nuevo agente terapéutico contra el cáncer.
Objetivos: Analizar la toxicidad, la alergenicidad y el potencial de los péptidos del líquido celómico de L. variegatus como agentes inhibidores multidiana de las células cancerosas del CCR a través de un estudio in silico.
Métodos: Se procesaron diez péptidos del líquido celómico de L. variegatus utilizando el software UCSF Chimera para modelar la estructura tridimensional. Se utilizaron los servidores web ToxinPred y AllerTop para analizar la toxicidad y la alergenicidad de los péptidos, respectivamente. Las estructuras 3D de EGFR, AKT1, GSK3B, VEGFR2 y JAK3 se recuperaron de la base de datos PDBJ. Se utilizó el software MOE para realizar el acoplamiento molecular.
Resultados: El péptido 4 se une al bolsillo de unión de ATP de la proteína GSK3B con el valor de afinidad de unión más fuerte (-8,68 kcal/mol). Los resultados del acoplamiento entre EGFR y péptidos mostraron que el péptido 10 se une al bolsillo de unión de ATP con la afinidad de unión más baja (-9,52 kcal/mol). El péptido 2 se une al bolsillo de unión de ATP de AKT1 con el valor de afinidad de unión más bajo (-9,16 kcal/mol). El péptido 3 tiene el valor de afinidad de unión más bajo del bolsillo de unión de ATP de JAK3 (-8,67 kcal/mol). El péptido 7 se une al bolsillo de unión de ATP de VEGFR2 con la afinidad de unión más fuerte (-9,67 kcal/mol).
Conclusiones: Los péptidos de L. variegatus tienen potencial como agentes anti-CRC multidiana al inhibir la actividad de las proteínas GSK3B, EGFR, AKT1, JAK3 y VEGFR2 a través de la acción inhibidora competitiva de ATP basada en un estudio in silico.
