PARP Degrader

Thalidomide-piperidine-C-Pip-C2-Pip-C2-OH (Compound C6) is a conjugate of the linker and E3 ligase ligand, that can be used in synthesis of PROTAC PARP1 degrader-30 (HY-168722).

CW-2 is a CRBN-recruited PARP1 PROTAC degrader. CW-2 triggers multiple downstream biological effects including DNA damage accumulation, impaired DNA repair, mitochondrial-mediated apoptosis, intracellular ROS buildup and G1/S cell cycle arrest, as well as the regulation of oxidative phosphorylation, p53, PI3K-Akt and MAPK alongside ubiquitin proteolysis pathways. CW-2 enhances cell membrane permeability and intracellular platinum enrichment, exhibits detectable pharmacokinetic profiles after intraperitoneal administration in rats and drives differential gene expression. CW-2 can be applied to research on triple-negative breast cancer, non-small cell lung cancer, cisplatin-resistant non-small cell lung cancer, colon cancer and pancreatic cancer.

Apoptosis inducer 34 (Compound 4) is a small molecule compound that induces apoptosis by directly activating the intrinsic apoptotic pathway. Apoptosis inducer 34 promotes Apaf-1 oligomerization to form mature apoptosomes, thereby activating caspase-9 and caspase-3. It significantly activates the apoptotic pathway in Jurkat cells by enhancing the cytochrome c-dependent apoptotic signaling pathway, inducing PARP cleavage and chromosomal DNA fragmentation. Furthermore, Apoptosis inducer 34 exhibits low toxicity to normal cells, demonstrating potential for selective targeting of cancer cells. Apoptosis inducer 34 is a promising candidate for studying cancer related to apoptotic pathways.
