摘 要:BACKGROUND Centipedes have been used to treat tumors for hundreds of years in ***,current studies focus on antimicrobial and anticoagulation agents rather than *** molecular identities of antihepatoma bioactive components in centipedes have not yet been extensively *** is a challenge to isolate and characterize the effective components of centipedes due to limited peptide purification technologies for animal-derived *** To purify,characterize,and synthesize the bioactive components with the strongest antihepatoma activity from centipedes and determine the antihepatoma *** An antihepatoma peptide(scolopentide)was isolated and identified from the centipede scolopendra subspinipes mutilans using a combination of enzymatic hydrolysis,a Sephadex G-25 column,and two steps of high-performance liquid chromatography(HPLC).Additionally,the CCK8 assay was used to select the extracted fraction with the strongest antihepatoma *** molecular weight of the extracted scolopentide was characterized by quadrupole time of flight mass spectrometry(QTOF MS),and the sequence was matched by using the Mascot search *** on the sequence and molecular weight,scolopentide was synthesized using solid-phase peptide synthesis *** synthetic scolopentide was confirmed by MS and *** antineoplastic effect of extracted scolopentide was confirmed by CCK8 assay and morphological changes again in *** antihepatoma effect of synthetic scolopentide was assessed by the CCK8 assay and Hoechst staining in vitro and tumor volume and tumor weight in *** the tumor xenograft experiments,qualified model mice(male 5-week-old BALB/c nude mice)were randomly divided into 2 groups(n=6):The scolopentide group(0.15 mL/d,via intraperitoneal injection of synthetic scolopentide,500 mg/kg/d)and the vehicle group(0.15 mL/d,via intraperitoneal injection of normal saline).The mice were euthanized by cervical dislocation after 14 d of con
