Fifteen pentapeptide analogs of C-terminal fragment of peptide T, H-Ala-Ser-Thr-Thr-Thr-Asn-Tyr-Thr-OH, were prepared and tested for human monocyte chemotaxis. Structure-activity studies suggest that the potent chemotactic activity of H-Thr-Thr-Asn-Tyr-Thr-OH is mediated through the polar properties of the C-terminal carboxyl group and Thr side chains at the critical positions 5 and 8, while the hydroxyl group of N-terminal Thr and its free amino function are not essential requirements for CD4 receptor interactions.

D013329 Structure-Activity Relationship The relationship between the chemical structure of a compound and its biological or pharmacological activity. Compounds are often classed together because they have structural characteristics in common including shape, size, stereochemical arrangement, and distribution of functional groups.

D015704 CD4 Antigens 55-kDa antigens found on HELPER-INDUCER T-LYMPHOCYTES and on a variety of other immune cell types. They are members of the immunoglobulin supergene family and are implicated as associative recognition elements in MAJOR HISTOCOMPATIBILITY COMPLEX class II-restricted immune responses. On T-lymphocytes they define the helper/inducer subset. T4 antigens also serve as INTERLEUKIN-15 receptors and bind to the HIV receptors, binding directly to the HIV ENVELOPE PROTEIN GP120.

D015717 Peptide T N-(N-(N(2)-(N-(N-(N-(N-D-Alanyl L-seryl)-L-threonyl)-L-threonyl) L-threonyl)-L-asparaginyl)-L-tyrosyl) L-threonine. Octapeptide sharing sequence homology with HIV envelope protein gp120. It is potentially useful as antiviral agent in AIDS therapy. The core pentapeptide sequence, TTNYT, consisting of amino acids 4-8 in peptide T, is the HIV envelope sequence required for attachment to the CD4 receptor. HIV Peptide T,Peptide T, HIV
