Description
Summary:	•Enzymatic cleavage of native fucoidan FeF by fucoidanase FFA1 yielded fractions HMP and LMP.•HMP are polymeric fragments of FeF that have a regular structure.•FeF and HMP have anticancer effect on colon cancer cells in vitro.•Anticancer effect of HMP was comparable to the activity of FeF but not identical. Enzymatic depolymerization of fucoidans attracts many researchers due to the opportunity of obtaining standardized fucoidan fragments. Fucoidanase catalyzes the cleavage of fucoidan from Fucus evanescens (FeF) to form low molecular weight products (LMP) and a polymeric fraction (HMP) with 50.8 kDa molecular weight and more than 50% yield. NMR spectroscopy shows that the HMP fraction has regular structure and consists of a repeating fragment [→3)-α-l-Fucp2,4OSO3−-(1 → 4)-α-l-Fucp2,4OSO3−-(1 → 4)-α-l-Fucp2OSO3−-(1→]n. The anticancer effects of FeF fucoidan and its derivative (HMP) were studied in vitro on colon cancer cells HCT-116, HT-29, and DLD-1. The anticancer activity of the HMP fraction was found to be slightly lower than that of the FeF fucoidan. Research and practical applications of the enzyme include modification of native fucoidans for purposes of regular and easier characterized derivatives acquisition.
