Synthesis and evaluation of the aldolase antibody-derived chemical-antibodies targeting α5β1 integrin.

ABSTRACT: Integrin α5β1 is an important therapeutic target that can be inhibited using an aldolase antibody (Ab)-derived chemical-Ab (chem-Ab) for the treatment of multiple human diseases, including cancers. A fairly optimized anti-integrin α5β1 chem-Ab 38C2-4e was obtained using an in situ convergent chemical programming (CP) approach, which minimized the time and effort needed to develop a chem-Ab. Multiple Ab-programming agents (PAs) 4a-e could be prepared rapidly using the Cu-catalyzed alkyne-azide coupling (Cu-AAC) reaction of an α5β1 inhibitor 2 with multiple linkers 3a-e, either before or after conjugating the linkers into Ab 38C2 binding sites. In these two-steps processes, the products after step 1 can be used in the next step without performing an extensive purification or analysis of the
