CM03 is a potent inhibitor of cell growth in PDAC cell lines, and has anticancer activity in PDAC models, with a superior profile compared to gemcitabine, a commonly used therapy. Whole-transcriptome RNA-seq methodology has been used to analyze the effects of this quadruplexbinding small molecule on global gene expression. This has revealed the down-regulation of a large number of genes, rich in putative quadruplex elements and involved in essential pathways of PDAC survival, metastasis, and drug resistance. The changes produced by CM03 represent a global response to the complexity of human PDAC and may be applicable to other currently hard-to-treat cancers.

- Anti - proliferative Activity: CM03 shows high anti - proliferative activity against pancreatic cancer cell lines. The GI50 values are 9.0 nM, 15.6 nM, 26.5 nM and 15.5 nM in Mia Paca - 2, Panc - 1, Capan - 1 and BxPC - 3 cells respectively [1]
- Synergistic Effect with SAHA: CM03 and the histone deacetylase (HDAC) inhibitor SAHA have synergistic effects at concentrations close to and below their individual GI50 values in both gemcitabine - sensitive and resistant pancreatic cancer cell lines. Immunoblot analysis shows that the combination treatment can increase the levels of γ - H2AX and cleaved PARP proteins, indicating an increase in DNA damage (double - strand break events) and apoptosis induction [1] - Mechanism of Action: CM03 can stabilize G4, down - regulate more G4 - containing genes, and increase the occurrence of double - strand break events due to the torsional strain on DNA and chromatin structure [1] γ-H2AX protein levels are increased in MIA PaCa-2 and PANC-1 upon binding of CM03 (0.4 μM; 24 or 48 hours) to SAHA [1]. High anti-proliferative action against pancreatic cancer cell lines is demonstrated by CM03 (0-100 nM; 96 h) [2]. |

Western Blot Analysis[1]
Cell Types: MIA PaCa-2 and PANC-1 Tested Concentrations: 0.4 μM Incubation Duration: 24 hrs (hours) for MIA PaCa-2 and 48 hrs (hours) for PANC-1 Experimental Results: γ-H2AX protein levels Dramatically increased with SAHA (1 μM) combination. Cell proliferation assay[2] Cell Types: MIA PaCa-2, PANC-1, Capan-1 and BxPC-3 Tested Concentrations: 0-100 nM Incubation Duration: 96 hrs (hours) Experimental Results: MIA exhibits high anti-proliferative activity against pancreatic cancer cell lines The GI50s of PaCa-2, PANC-1, Capan-1 and BxPC-3 are 9.0 nM, 15.6 nM, 26.5 nM and 15.5 nM respectively. - Proliferation Inhibition Assay: Culture Mia Paca - 2, Panc - 1, Capan - 1 and BxPC - 3 pancreatic cancer cell lines, add different concentrations of CM03 to the culture medium, and incubate for 96 h. Then use the sulforhodamine B (SRB) cytotoxicity assay to detect the proliferation of cancer cells, so as to evaluate the anti - proliferative activity of CM03 [1] - Immunoblot Analysis: Culture pancreatic cancer cell lines, treat them with CM03 and SAHA alone or in combination. After a certain period of incubation, extract cell proteins, and use immunoblotting to detect the levels of γ - H2AX and cleaved PARP proteins to evaluate the degree of DNA damage and apoptosis induction [1] |

| Additional Infomation |
- Mechanism of Synergy: SAHA relaxes condensed chromatin, resulting in a higher level of G4 formation. In turn, CM03 can stabilize more G4s, leading to the down - regulation of more G4 - containing genes and a higher incidence of double - strand breaks due to torsional strain on DNA and chromatin structure [1]
