TNI-97
TNI-97 is a selective and orally active HDAC6 inhibitor, with an IC50 of 0.2 nM. TNI-97 potently inhibited TNBC cell MDA-MB-453 growth and clonogenicity. TNI-97 induces PANoptosis including apoptosis, necroptosis and pyroptosis in MDA-MB-453 cells. TNI-97 shows antitumor activity in the mice carrying the MDA-MB-453 xenograft or carrying murine-derived TNBC cell allografts. TNI-97 can be used for the study of triple-negative breast cancer.

TNI-97 demonstrates antitumor activity with GI50 values of 0.8 μM in MDA-MB-453 cells and 5.4 μM in MDA-MB-468 cells[1]. TNI-97 (1 μM, 24 h) significantly induces α-tubulin acetylation than does Ricolinostat (ACY-1215) (HY-16026) under lower concentrations and does not induce histone H3 acetylation in MDA-MB-453 cells[1]. TNI-97 (1-2 μM, 14 days) dose-dependently inhibits the MDA-MB-453 colony formation[1]. TNI-97 (2.5-5 μM, 48 h) induces apoptosis, necroptosis and pyroptosis in MDA-MB-453 cells[1].

Animal Model:NOD-PrkdcscidlL2rgtm1 (NSIG) female mice (6-8 weeks) carrying the MDA-MB-453 xenograft (1 × 107) [1]
-
Dosage:20, 40 mg/kg
-
Administration:p.o. 5 on/2 off for 2 weeks
-
Result:Exhibited a dose-dependent inhibition of tumor growth, achieving tumor growth inhibition (TGI) rates of 91 and 54% at doses of 40 and 20 mg/kg, respectively. Induced pANoptosis in tumor tissue. Upregulated cleaved-caspase 3, cleavedGSDMD, and phosphorylated MLKL expression. Had no impact on the counts and proportions of white blood cells, red blood cells, and platelets. Showed no significant morphological abnormalities.

Animal Model:BALB/c mice (6-8 weeks) carrying murine-derived TNBC cell allografts (1 × 106Dosage:40 mg/kgAdministration:p.o. 5 on/2 off for 2 weeksResult:Exhibited significant reductionsin both tumor weight and tumorsize of 4T1 allografts (TGI = 60%). Showed no significant alteration in body weight.
