FCW34
FCW34 is a cell-permeable, selective Sialyltransferase inhibitor. FCW34 inhibits α2,3-N-linked ST3GALIII (IC50 1.74 μM) and α2,6-N-linked ST6GALI (IC50 3.6 μM), reducing N-glycoprotein sialylation. FCW34 decreases cell migration ability by inhibiting the Talin/Integrin/FAK/Paxillin and Integrin/NFκB signaling pathways. FCW34 significantly inhibits tumor growth, reduces angiogenesis, and suppresses spontaneous lung metastasis in a nude mouse model of breast cancer. FCW34 can be used for research on breast cancer.

In Vitro
FCW34 (10-20 μM; 48 h) disrupts talin-driven integrin activation by reducing the colocalization of integrin β1 and β3 with phospho-talin-1 in MDA-MB-231 cells[1].
FCW34 inhibits integrin sialylation in MDA-MB-231 cells[1].
FCW34 (>60 μM; 48 h) does not exhibit antiproliferative effects on MDA-MB-231 cells at concentrations up to 60 μM[1].

-
Animal Model:Athymic nude mice (BALB/cAnN.Cg-Foxn1nu/CrlNarl, 4-5 weeks of age, female)[1]
-
Dosage:10 mg/kg
-
Administration:every other day
-
Result:Displayed profound tumor suppression and delayed lung metastasis.
Showed a significantly smaller number of metastatic foci in the lungs and fewer metastatic nodules in adjacent lymph node sections compared to control.
Revealed a significantly smaller number of vessels surrounding tumor nodules and significantly reduced angiogenesis.
Showed significantly less accumulation of Ki-67-positive cells than in control mice.
Indicated no detrimental effects on health based on blood tests and body weight assessments.
