Chemical dissection of selective myeloid leukemia-1 inhibitors: How they were found and evolved.

Myeloid cell leukemia-1 (MCL-1), a key anti-apoptotic protein within the BCL-2 family, is essential in regulating cell survival, particularly in cancer, where its overexpression is often linked to therapeutic resistance. This review begins with an overview of BCL-2-mediated apoptosis, highlighting the pivotal role of MCL-1 in cellular homeostasis. We then focus on the structure and function of MCL-1, elucidating how its unique structural features contribute to its function and interaction with pro-apoptotic proteins.

An Entropy-Driven Multipedal DNA Walker Microsensor for In Situ Electrochemical Detection of ATP.

Microelectrode- and nanoelectrode-based electrochemistry has become a powerful tool for the in situ monitoring of various biomolecules in vivo. However, two challenges limit the application of micro- and nanoelectrodes: the difficulty of highly sensitive detection of nonelectroactive molecules and the specific detection of target molecules in complex biological environments. Herein, we propose an electrochemical microsensor based on an entropy-driven multipedal DNA walker for the highly sensitive and selective detection of ATP.
