CD4-Pseudomonas exotoxin hybrid proteins: modulation of potency and therapeutic window through structural design and characterization of cell internalization.

abstract：:Benzylated peptides with a primary amino acid sequence corresponding to either human CD4(81-92) (#18), or chimpanzee CD4(81-92) (#18C), were equipotent inhibitors of human immunodeficiency virus type 1 (HIV-1) infection of CD4+ cells and high-affinity binding of 125I-gp120 to CD4+ cells. The chimpanzee-based CD4(81-92...
