dextran sulfate

A high-molecular weight, branched-chain polysaccharide polymer of d-glucose that is permeable to water and forms a viscid gelatinous material; it is synthesised commercially or naturally by glycosyl transferases on the surface of certain bacteria, and had been claimed to have anti-HIV activity (by inhibiting HIV-1 and HIV-2 binding to CD4+ cells). Therapeutic trials  showed no such efficacy.


a water-soluble polysaccharide of glucose (dextrose) produced by the action of Leuconostoc mesenteroides on sucrose; used as a plasma volume extender. Several preparations of dextran are used as anticoagulants.
