    Ibetazol

    		Ras Cancer
    Ibetazol is a Importin β1 (KPNB1) inhibitor and nucleocytoplasmic transport disruptor. Ibetazol binds covalently to Cys585 of Importin β1, blocks both Importin β1-mediated direct transport and Importin α-dependent nuclear import processes, without affecting transport mediated by other nucleocytoplasmic transport proteins. Ibetazol induces cytoplasmic accumulation of Importin α1, and inhibits nuclear import of substrates carrying nuclear localization signals (NLS), including the NLS-cMyc reporter gene, RelA/p65 and SREBP1. Ibetazol triggers spindle malformation and chromosome misalignment by disrupting the mitotic function of Importin β1. Ibetazol inhibits the proliferation of cells expressing wild-type Importin β1. Ibetazol has a high activity-cytotoxicity window, lacks intrinsic fluorescence, and acts rapidly on nucleocytoplasmic transport processes. Ibetazol serves as a tool compound for investigating nuclear import processes specifically mediated by Importin β1 .

    Fulvestrant (S enantiomer)

    ICI 182780 (S enantiomer); ZD 9238 (S enantiomer); ZM 182780 (S enantiomer)

    		 Drug Isomer Estrogen Receptor/ERR p38 MAPK Apoptosis Cancer
    Fulvestrant (ICI 182780; ZD 9238) S enantiomer is the S-enantiomer of Fulvestrant (HY-13636), a potent estrogen receptor inhibitor. Fulvestrant binds to and blocks the estrogen receptor, promotes its degradation, and thereby inhibits receptor dimerization, nucleocytoplasmic shuttling and transcriptional activity. Fulvestrant effectively blocks estrogen signaling, MAPK pathway activation and ER-regulated protein expression. Fulvestrant induces apoptosis, inhibits the proliferation of breast cancer and prolactinoma cells, and reduces the mineralization level, alkaline phosphatase activity and osteocalcin expression of preosteoblasts. Prenatal exposure to Fulvestrant impairs ovarian follicular development and causes ovarian structural damage. Fulvestrant has been widely used in studies related to breast cancer, prolactinoma and other conditions .

    2-Azido-2-deoxy-D-glucose, 98%

    2-ADG, 98%

    		 Biochemical Assay Reagents OGT Cancer
    2-Azido-2-deoxy-D-glucose, 98% (2-ADG, 98%) is a substrate of O-GlcNAc transferase (OGT). 2-Azido-2-deoxy-D-glucose, 98% can be transferred from UDP-GlcAz to proteins in vitro via OGT mediation. When delivered as AcGlcAz, 2-Azido-2-deoxy-D-glucose, 98% enables the labeling and investigation of O-GlcNAc-modified nuclear and cytoplasmic proteins in cells. 2-Azido-2-deoxy-D-glucose, 98% undergoes strain-promoted [3+2] azide-alkyne cycloaddition (SPAAC) with technetium- 99m-labeled dibenzocyclooctyne derivatives in vivo. 2-Azido-2-deoxy-D-glucose, 98% can be used in sarcoma-related research .
