SMILES: C[C@@]([C@@](CC=C1[C@@]2([H])C[C@H](O)[C@@H](O)C1(C)C)([H])[C@@]2(C)C3=O)(C[C@@H](O)[C@]4([H])[C@@](C)(O)C(CCC(C)(C)OC(C)=O)=O)[C@@]4(C3)C
Biological Activity: Cucurbitacin IIa (Hemslecin A) is an orally active, blood-brain barrier-permeable EGFR inhibitor with an IC50 of 1.455 nM against human EGFR. Cucurbitacin IIa induces caspase-3-dependent apoptosis, downregulates survivin expression, enhances autophagy levels, disrupts the actin cytoskeleton via actin aggregation, arrests the cell cycle at the G2/M phase, and exerts anti-inflammatory activity by inhibiting the EGFR-MAPK signaling pathway. Cucurbitacin IIa can be used in the research of inflammation-related diseases, depression, and cancers such as non-small cell lung cancer[1][2][3][4].

Cucurbitacin IIa (Standard) | ≥98% | Cucurbitacin IIa (Hemslecin A) (Standard) is the analytical standard for Cucurbitacin IIa (HY-N1988). This product is used for research and analytical applications. Cucurbitacin IIa is an orally active, blood-brain barrier-penetrating EGFR inhibitor with an IC50 of 1.455 nM for human EGFR. Cucurbitacin IIa induces caspase-3 dependent cell apoptosis, downregulates survivin expression, enhances autophagy levels, disrupts the actin cytoskeleton through actin aggregation, blocks the cell cycle at the G2/M phase, and inhibits the EGFR-MAPK signaling pathway to exert anti-inflammatory activity. Cucurbitacin IIa can be used in research on inflammatory-related diseases, depression, and non-small cell lung cancer and other cancers. | ||||||||||||||||||||
