5-AMINO-2-(4-TERT-BUTYLPHENOXY)PYRIDINE Chemical Properties,Usage,Production

Description

CB-103 (218457-67-1) is an orally active inhibitor of the Notch signaling activation complex (IC50’s from 0.9 to 3.9 μM in various cell-based assays), the most downstream level of the Notch signaling pathway. It inhibited the growth of Notch-addicted human T cell acute lymphoblastic leukemia cells as well as other cell lines.? CB-103 also inhibited the growth of human breast cancer and leukemia xenografts without the intestinal toxicity associated with γ-secretase Notch inhibitors.

Uses

Limantrafin (CB-103) is a first-in-class, orally active protein-protein interaction (PPI) inhibitor of the NOTCH transcriptional activation complex. Limantrafin has anti-tumor activity[1][2][3][4].

in vivo

Limantrafin inhibits NOTCH dependent cellular processes in mice^[2].
Limantrafin blocks in vivo growth of PDX models of T-ALL^[2].
Limantrafin (25 mg/kg; i.p./p.o.; 2x daily; for 2 weeks) inhibits growth of GSI/Mab resistant triple negative breast cancer^[3].
Limantrafin exhibits anti-tumor activity in xenograft models of human T-ALL and mouse mammary tumors^[3].

Animal Model:	NSG mice, triple negative breast cancer mouse xenograft model^[3]
Dosage:	25 mg/kg
Administration:	Oral administration/Intraperitoneal injection; 2x daily; for 2 weeks
Result:	Inhibited growth of GSI/Mab resistant triple negative breast cancer.
