Autophagy-IN-2 (Compound 7h) 是一种自噬通量 (autophagic flux) 抑制剂。Autophagy-IN-2 诱导癌细胞凋亡 (Apoptosis)，可用于三阴性乳腺癌研究。

Autophagy-IN-2 (Compound 7h) is an autophagic flux inhibitor. Autophagy-IN-2 induces cancer cell apoptosis and can be used for triple-negative breast cancer research [1].

Autophagy-IN-2 (Compound 7h) (0-200 μM, 48 h) shows anti-viability activities against various cancer cells [1]. Autophagy-IN-2 (0-20 μM, 0-48 h) suppresses autophagic flux and impairs DNA repair through down-regulating chromatin ubiquitination in a p62-dependent manner [1]. Autophagy-IN-2 (0-20 μM, 48 h) induces cell cycle arrest at S-phase and mitochondria-dependent intrinsic apoptosis [1]. Cell Viability Assay [1] Cell Line: MDA-MB-231, MDA-MB-468, SCC25, HSC-3, HCT116, SW620, PC3, Aspc, PNAC, U87, U251 and LN229 Concentration: 0-200 μM Incubation Time: 48 h Result: Showed anti-viability activities with IC 50 values of 8.31 ± 1.05, 6.03 ± 0.82, 18.64 ± 2.92, 24.03 ± 3.75, 35.53 ± 7.52, 25.43 ± 2.42, 17.48 ± 1.27, 26.89 ± 5.23, 19.25 ± 3.96, 15.37 ± 1.78, 12.92 ± 2.38 and 61.35 ± 11.61 μM against MDA-MB-231, MDA-MB-468, SCC25, HSC-3, HCT116, SW620, PC3, Aspc, PNAC, U87, U251 and LN229 cells, respectively. Western Blot Analysis [1] Cell Line: MDA-MB-231 and MDA-MB-468 Concentration: 5, 10 and 20 μM Incubation Time: 0, 6, 12, 24, 36 and 48 h Result: Significantly induced to LC3B-II in a dose - and time-dependent manner, resulted in a p62 accumulation in TNBC cells, increased γH2AX in a dose and time-dependent manner, activated the phosphorylation of ATM, NBS1 and SMC1, increased p62 in the nucleus and cytoplasm in a dose-dependent manner, and significantly reduced DNA-damage-induced formation of H2A poly-ubiquitin chains. Decreased the cellular levels of Cyclin A, Cyclin B, CDK1 and CDK2, increased P21 and the phosphorylation levels of CHK1 (Serine 345) and CHK2 (Threonine 68), and increased cytochrome c, cleaved caspase-3, cleaved caspase-9 and cleaved PAPR in a dose-dependent manner. Cell Cycle Analysis [1] Cell Line: MDA-MB-231 and MDA-MB-468 Concentration: 5, 10 and 20 μM Incubation Time: 48 h Result: Induced cell cycle arrest at S-phase. Apoptosis Analysis [1] Cell Line: MDA-MB-231 and MDA-MB-468 Concentration: 5, 10 and 20 μM Incubation Time: 48 h Result: Dramatically induced cell apoptosis in TNBC cells and obviously increase the proportion of late-phase apoptosis in a dose-dependent manner.

Autophagy-IN-2 (Compound 7h) (5 and 15 mg/kg; i.p.; every 3 days for 3 weeks) suppresses tumor growth in a dose-dependent manner [1]. Animal Model: Six-week-old female NOD/SCID mice, MDA-MB-231 xenograft [1] Dosage: 5 mg/kg, 15 mg/kg Administration: Intraperitoneal injection, every 3 days for 3 weeks Result: Suppressed human TNBC tumor growth in a dose-dependent manner and resulted in a concentration-dependent upregulation of LC3B-II, p62, γH2AX and PARP.
