PARP1-IN-58 is a ROS-responsive prodrug constructed based on a natural stilbene scaffold, and its active parent nucleus 24c acts as a selective PARP-1 inhibitor. PARP1-IN-58 only hydrolyzes to release the active parent compound in the high-ROS microenvironment of tumors; the active parent compound competitively binds to PARP-1 and blocks DNA single-strand damage repair, upregulates intracellular ROS levels, reduces mitochondrial membrane potential, and thereby induces cell cycle arrest and mitochondria-dependent apoptosis. PARP1-IN-58 exerts potent proliferation-inhibiting effects on BRCA-deficient breast cancer cells under simulated tumor oxidative stress conditions, and exhibits tumor growth inhibitory activity in breast cancer xenograft models. PARP1-IN-58 can be used in cancer-related research .

Amino acids are the fundamental components that sustain life activities, playing roles in ATP generation, promoting nucleotide synthesis, and maintaining cellular redox balance. Moreover, dysregulation of amino acid consumption is a significant potential regulatory mechanism leading to impaired anti-tumor immunity in immune cells. The normal functioning of immune cells relies on amino acid metabolic pathways to obtain energy and materials, and upon activation, they reprogram their metabolism to support growth, proliferation, and effector functions. Additionally, metabolic disorders of specific amino acids (such as branched-chain amino acids, glutamine, and arginine) can exacerbate mitochondrial dysfunction and oxidative stress, thereby promoting myocardial fibrosis and cardiac cell damage. Therefore, conducting research related to amino acid metabolism holds promise for discovering potential drugs for diseases related to cancer, immunity, and metabolism.

MCE can provide 195 kinds of metabolites of amino acid metabolic pathways, which can be used for drug screening in various diseases such as cancer, immune disorders, metabolic diseases, mitochondrial-targeted diseases
