In repeated experiments with HIV-1 IIIB, soluble and micronized CAP, cellulose sulfate, poly(naphthalene sulfonate), poly(styrene-4-sulfonate) and BufferGel, respectively, caused a ≥ 140-fold reduction in infectivity, while dextran sulfate, carrageenan and Carbomer 974P (pH 7), respectively, were less effective (4- to 25-fold reduction in infectivity).
Adult female Xenopus laevis were anesthetized with tricaine methane sulfonate (MS-222, Sigma Chemical Co).
They include: (1) sulfate esters of polysaccharides {carrageenan [ 1 16 17 18 19 ] , cellulose sulfate [ 12 13 14 15 ] , and dextran or dextrin sulfate [ 1 2 3 4 5 6 7 8 9 10 11 ] }; (2) aryl sulfonates {poly(naphthalene sulfonate) [ 22 23 24 ] and poly(styrene-4-sulfonate) [ 20 21 ] }; and (3) aliphatic {Carbomer 974P/BufferGel [ 25 26 27 28 29 ] } and aromatic carboxylates {CAP [ 30 31 32 33 34 35 36 37 ] }. The anti-HIV-1 properties of these polymers are expected to depend on their complexation with virus proteins which is likely to occur mainly through the formation of salt linkages or ion pairs between oppositely charged groups on the polymers and virus proteins, respectively [ 56 ] . However, the anti-HIV-1 properties of these polymers may depend not only on their charge density, but also on the characteristics of their uncharged portions, which may be involved in hydrophobic and hydrogen bonding interactions which can elicit profound conformational changes in hydrophobic regions of proteins and cause disassembly of complex proteins consisting of subunits [ 57 ] . For these reasons it is not be expected that all anionic polymers, considered as anti-HIV-1 microbicides, would have similar biological activities.
5), and show that only CAP and to a lesser extent poly(napthalene sulfonate) elicited gp41 six-helix bundles detectable by ELISA.
Among the sulfonates and polysaccharide sulfates, carrageenan and poly(napthalene sulfonate) had lower anti-coagulant activity in comparison with cellulose sulfate, dextran sulfate and poly(styrene-4-sulfonate) (Fig.
