PIC 024-4 and PRO 2000 are naphthalene sulfonate polymers that bind to
CD4 with nanomolar affinity and block binding of gp120. Both have act
ivity against human immunodeficiency virus type 1 in 1-19 cells, perip
heral blood mononuclear cells, and primary monocyte/macrophages, are s
ynergistic with zidovudine, and do not inhibit tetanus toxoid-stimulat
ed T-cell proliferation at anti-human immunodeficiency virus type 1 co
ncentrations.
