designed and synthesized. The key to the synthesis was achieved by employing an esterification reaction and click chemistry. All of the new derivatives were tested for cytotoxicity against five human tumor cell lines, including HL-60, SMMC-7721, A-549, MCF-7, and SW480 with IC50 values ranging from 0.13 to 21.53 μM. Most of the derivatives exhibited potent cytotoxicity, especially compound 17 (IC50 = 0
chemical reagents has played an essential role in the treatment of human diseases. However, the reagents currently used are limited to the covalent modification of cysteine and lysine residues. It is thus desirable to develop novel methods that can covalently modify other residues. Despite the fact that the carboxyl residues are crucial for maintaining the protein function, few selective labeling reactions

The present disclosure relates to chemical compounds that inhibit HP1-mediated heterochromatin formation, pharmaceutical compositions containing such compounds, methods of identifying such compounds, and their use in the treatment of disorders related to heterochromatin formation such as, for example, a disorder of cellular proliferation (e.g., cancer). This abstract is intended as a scanning tool for purposes of searching in the particular art and is not intended to be limiting of the present invention.

Biotinâdisulfideâcoumarin conjugates are designed and synthesized as novel fluorescent sensors for cancer targeted intracellular thiol imaging in living organisms. In vitro experiments disclose that probe 6 is preferentially taken up by biotin receptor-positive A549 tumor cells through receptor mediated endocytosis.
