Ipragliflozin L-Proline

Sodium‒glucose cotransporter 2 (SGLT2) inhibitors have become viable therapeutic options for treating breast cancer. Diabetes is the primary source of these medications. This research examines how SGLT2 blockers can induce apoptosis, decrease the amount of glucose taken up by cancer cells, and modify key signaling pathways, such as the PI3K/AKT/mTOR and MAPK pathways. The effects of four different SGLT2 inhibitors on breast cancer cells were investigated in this study via both in vitro and in vivo testing: dapagliflozin, ipragliflozin, canagliflozin, and empagliflozin. The potential synergistic effects of these inhibitors with conventional chemotherapy medications were also examined. This review explores the complex relationship between SGLT2 inhibitors and breast cancer, examining how drugs interact with this disease at various stages of its development. Additionally, this study highlights how SGLT2 inhibitors may be used in conjunction with precision medicine techniques to treat breast cancer. Although encouraging outcomes have been noted, this review highlights the necessity of additional clinical studies to evaluate the safety and effectiveness of SGLT2 blockers in patients with breast cancer, in addition to ongoing research into the molecular mechanisms underlying the anticancer effects of these drugs.

Amyloid formation is involved in widespread health conditions such as Alzheimer's disease, Parkinson's disease, and type-2 diabetes. Amyloid fibrils have a similar cross-β architecture, but fibrils formed by a single protein sequence can have diverse structures, varying with time, self-assembly conditions, and sequence modifications. Fibril structure has been proposed to be diagnostic of disease, but why different structures result under different conditions, especially in vitro, remains elusive. We previously identified a small molecule, YX-I-1, which inhibits in vitro amyloid formation by islet amyloid polypeptide (IAPP), a peptide hormone whose amyloid formation is involved in type-2 diabetes. Here, using YX-I-1 as a lead, we identified regulator-approved drugs with similar structures by chemical similarity analysis and substructure searches and monitored the effect of 24 of these potential ligands on IAPP amyloid assembly in vitro. We show that one such compound, canagliflozin (Invokana), a type-2 diabetes drug already in clinical use, can strongly delay the kinetics of IAPP amyloid formation, an activity independent of its intended mode of action [sodium-glucose linked transporter 2 (SGLT2) inhibitor] that may have important therapeutic implications. Combining analysis of amyloid self-assembly kinetics, biophysical characterization of monomer and fibril binding, and cryo-EM of the assembly products, we show that YX-I-1 and canagliflozin target IAPP early in aggregation, remodeling the energy landscape of primary nucleation and profoundly altering the resulting fibril structures. Early binding events thus imprint long-lasting effects on the amyloid structures that form.
