The invention refers to the synthetic fat of cnal-x2-x3-nh2 formula, wherein: cn is a fatty acid selected from a group of fats from 012 to C18； X1 is at least a glycerin molecule； X2 is at least two natural amino acids, with net load reopening and / or non protein； X3 may or may not exist, and when it does, there is at least one amino acid. Antibacterial activities were carried out on the pathological bacteria (step hylococcus aureus, enterocaocus faecalis, Eschericia coli, Pseudomonas aeruginosa, Klebsiella P eumoniae, acinetobater baurnannit serraba marcescens). Longtail sharkIn addition, in haemolyticus and salinarius with a minimum inhibitory concentration (CM) of 8-50 Utd, n also showed toxicity to human red algae and mosquito larvae at assessed concentrations of 100 PM and 3.13-50.0 PM.La presente inVenCión se refiere a lipOpáplidos sintéticos de formula Cnal-X2-X3-NH2 en donde: Cn es un ácido graso seleccionado del grupo que consiste de 012 a C18； X1 es al menos una molécula de glicina； X2 es al menos dos aminoácidos naturales con carga neta Reabra y/a no proteinogénicos； y. X3 puede estar presente o ausente y cuando está presente es al menos un aminoácido alitatico. Los lipopéptidos presentan actividad antibacteriana contra bacterias patógenas (Step hylococcus aureus, Enterocaocus faecalis, Escherichia coli, Pseudomonas aeruginosa, Klebsiella p eumoniae, Acinetobacter baurnannit Serraba marcescens. Staphylocaccus saprophyticus, StaPhylococcus haemolyticus y Streptocaccus salivarius) a concentraciones mínimas inhibitorias (CM') entre 8 a 50 utd, Adicionalmente, n presentaron toxicidad en eritrocitos humanos ni en larvas de mosquito en concentraciones entre 3,13 y 50,0 pM a na concentración evaluada de 100 pM,
