CW-2
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.

Biologische Aktivität
CW-2 (1.0-100 μM; 12-72 h) is stable in non-reductive solutions for 72 h, undergoes reductive decomposition within 12 h in the presence of ascorbic acid, and has an optimized octanol-water partition coefficient of 2.11 that supports enhanced membrane permeability[1].
CW-2 (60 μM; 4 h) exhibits enhanced cellular uptake in MDA-MB-231 cells, delivering a total intracellular PROTAC-2 concentration of 34.1 μM, which is higher than direct PROTAC-2 treatment[1].
CW-2 (24-72 h) exhibits stability in DMSO, PBS, and 10% FBS culture medium over 72 h, and undergoes time-dependent reduction when incubated with 3.0 equivalents of ascorbic acid over 12 h[1].
CW-2 (0.3-80.0 μM; 48 h) potently inhibits the proliferation of multiple cancer cell lines, including Cisplatin (HY-17394)-resistant A549/CDDP cells, with an IC50 of 0.72 μM against MDA-MB-231 cells[1].
CW-2 (0.5-2 μM; 24-48 h) concentration-dependently degrades PARP1 protein in MDA-MB-231 cells, with near-complete suppression at 2 μM, via the ubiquitin-proteasome pathway[1].
CW-2 (1 μM; 48 h) induces higher levels of DNA damage in MDA-MB-231 cells than Cisplatin, Olaparib (HY-10162), or PROTAC-2, as indicated by elevated γ-H2AX expression[1].
CW-2 (1 μM; 48 h) regulates apoptosis-related proteins in MDA-MB-231 cells, upregulating pro-apoptotic BAX, caspase-3, and cleaved caspase-3, and downregulating anti-apoptotic Bcl-2 to promote apoptosis[1].
CW-2 (1 μM; 48 h) reduces mitochondrial membrane potential in MDA-MB-231 cells, indicating compromised mitochondrial integrity[1].
CW-2 (1 μM; 48 h) induces significantly higher intracellular ROS accumulation in MDA-MB-231 cells than control, Cisplatin, Olaparib, or PROTAC-2, with an MFI 3.4×100 that of the control[1].
CW-2 (1 μM; 48 h) induces apoptosis in MDA-MB-231 cells, with 12.6% early apoptosis and 5.3% late apoptosis after 48 h of treatment at 1 μM[1].
CW-2 (1 μM; 48 h) induces cell cycle arrest in the G1 and S phases of MDA-MB-231 cells after 48 h of treatment at 1 μM[1].
CW-2 (1 μM; 24 h) alters the expression of 4495 genes in MDA-MB-231 cells, with significant enrichment in cancer-related pathways and cellular processes including DNA damage response[1].
CW-2 (1 μM；24 h) alters the transcription of 4495 genes in MDA-MB-231 cells, modulating pathways related to DNA damage, cell cycle, apoptosis, and oncogenic signaling[1].
