In this report, we describe the synthesis of cancer cell line specific peptide–gossypol conjugates and their cytotoxic effects. The aldehyde group of gossypol was utilized for conjugation, and thiazolidine (1 a ) as well as imine linkages (1 b ) were explored as traceless cleavable linkers (Figure 1).

Traceless linkers Conventional anticancer therapeutics often suffer from lack of specificity, resulting in poor therapeutic indexes and substantial toxicities to normal healthy tissues. Monoclonal antibodies have demonstrated considerable utility in cancer medicine, but their curative potential is often limited. Antibody–drug conjugates Staben et al. developed a chemoselective ligation approach that targets tertiary and heteroaryl amines coupled through a so-called “traceless” cleavable linker. After proteolytic cleavage of the linker, an adjacent self-immolating unit cyclizes upon itself and releases the payload in an unmodified form. A comparison of three linker types, (1) noncleavable, (2) cleavable but nontraceless, and (3) traceless, reveals up to an 8-fold improvement in T-cell proliferation when the traceless linker is used. Dec 28, 2019 · overcome these issues. Through the introduction of a traceless cleavable linker, the solubilizing tag can be selectively removed to generate native peptide. Here we describe the synthesis of a next-generation amine-reactive linker N-Fmoc-2-(7-amino-1-hydroxyheptylidene)-5,5-dimethylcyclohexane-1,3-dione
