产品描述 | MSC-4106 is an orally active and potent inhibitor ofYAP/TAZ-TEAD. MSC-4106 inhibitsTEAD1orTEAD3auto-palmitoylation and shows inhibitory effect on NCI-H226 tumor xenograft model[1]. MSC-4106 (10 μM, 24 h) inhibited SK-HEP-1 reporter and NCI-266 cell viability with IC50values of 4 nM and 14 nM, respectively[1]. MSC-4106 (10 μM, 6 h) crystallizes in the P-site of TEAD1, and against TEAD1 or TEAD3 palmitoylation in TEAD-Overexpressing HEK293 Cells by 97.3% and 75.9%, respectively[1]. MSC-4106 (10 μM, 4 d) targets TEAD indicated by a reduction in viability of NCI-H226 cells[1].
Cell Viability Assay[1] Cell Line: | NCI-H226 (YAP dependent); SW620 YAP/TAZ KO (Yap-independent) cells | Concentration: | 0, 3, 6, 9, 12, 15, 18, 21, 24, 26, 30 μM | Incubation Time: | 96 hours | Result: | Showed inhibitory effect to NCI-H226 and general cytotoxic to SW620 (IC50>30 μM). |
Immunofluorescence[1] Cell Line: | SK-HEP-1 | Concentration: | 0, 3, 6, 9, 12, 15, 18, 21, 24, 26, 30 μM | Incubation Time: | 24 hours | Result: | Inhibited YAP-TEAD interation. |
MSC-4106 (100 mg/kg/d; p.o.; 7 d) displays anti-tumor effect with controlled tumor volume and good tolerability with stable body weight in mice[1]. MSC-4106 (1, 5, 100 mg/kg/d; p.o.; 0-72 h) down-regulates Cyr61 (cysteine-rich angiogenic inducer 61) expression, the TEAD-regulated target gene, in tumor lysates at all time points at 100 mg/kg and 24 h at 5 mg/kg[1]. Pharmacokinetics (PK) profile in different species[1]
Parameter | Mouse | Rat | Dog | Cl (l/h/kg) | 0.2 | 0.7 | 0.05 | PO t1/2(h) | 45 | 40 | 3.6 | PO AUC (μg•h/mL) | 45 | 10 | 33 | Vss(L/kg) | 2 | 5 | 0.3 | F (%) | >90 | 80 | 18 | Note: PO studies were performed at 10 mg/kg; MSC-4106 was formulated in 20% Kleptose in 50 mM PBS at pH 7.4. Animal Model: | NCI-H226 xenograft model in H2d Rag2 female mice (9-week-old)[1] | Dosage: | 5, 100 mg/kg | Administration: | Oral gavage; once daily; 32 days | Result: | Resulted tumor growth controlled with 5 mg/kg while regressed with 100 mg/kg dosing after 32 treatment days. |
