We then evaluated the proliferation inhibition, apoptosis, and cell migration effects of Andro on the MDA-MB-436 cell line in vitro. The final biological evaluation confirmed that Andro was a highly effective single agent in the MDA-MB-436 xenograft model and had a low hERG-mediated cardiac toxicity. Therefore, Andro represents the first natural product, non-amide member of a novel nanomolar-potency PARP1/2 inhibitor family.Protein folding is a very complex process and, so far, the mechanism of folding still intrigues the research community. Despite a large conformational space available (O(1047) for a 100 amino acid residue), most proteins fold into their native state within a very short time. While small proteins fold relatively fast (a few microseconds) large globular proteins may take as long as several milliseconds to fold. During the folding process, the protein synthesized in the ribosome is exposed to the crowded environment of the cell and is easily prone to misfolding and aggregation due to interactions with other proteins or biomacromolecules present within the cell. These large proteins, therefore, rely on chaperones for their folding and repair. Chaperones are known to have hydrophobic patchy domains that play a crucial role in shielding the protein against misfolding and disaggregation of aggregated proteins. In the current article, Monte Carlo simulations carried out in the framework of the hydrophobic-polar (H-P) lattice model indicate that hydrophobic patchy
