英文摘要: Fucosylated chondroitin sulfate (FuCS-1) is a nontoxic and water-soluble depolymerized glycosaminoglycan obtained from the sea cucumber Thelenota ananas. Anti-HIV activities of FuCS-1 were evaluated in the present study. FuCS-1 was effective in blocking laboratory strain HIV-1(IIIB) entry and replication (4.26 mu g/mL and 0.73 mu g/mL, respectively), and inhibiting infection by clinic isolate HIV-1(KM018) and HIV-1(TC-2) (23.75 mu g/mL and 31.86 mu g/mL, respectively) as well as suppressing HIV-1 drug-resistant virus. It also inhibited HIV-2(ROD) and HIV-2(CBL-20) replication (100 mu g/mL). Notably, FuCS-1 showed highly effective antiviral activity against T-20-resistant strains (EC50 values ranging from 0.76 mu g/mL to 1.13 mu g/mL). Further studies indicated that FuCS-1 can potently bind the recombinant HIV-1 gp120 protein, but no inhibition of recombinant HIV-1 reverse transcriptase was observed. In conclusion, FuCS-1 inhibited several strains of HIV-1 replication with different potencies. These results suggest that FuCS-1 may possess great potential to be further developed as novel HIV-1 entry inhibitor for treatment of HIV/AIDS patients, particularly for those infected by T-20-resistant variants.
