Description

Isoangustone A is an anticancer and anti-inflammatory agent. Isoangustone A induces cancer cells apoptosis and autophagic cell death[1][2][3].

IC50 & Target

Apoptosis, Autophagy[2]

In Vitro

Isoangustone A (10 and 20 μM; 48 and 72 h) suppresses proliferation and induces G1 phase cell cycle arrest in SK-MEL-28 cells[1].
Isoangustone A (10 and 20 μM; 48 h) decreases the abundance of G1 phase-related proteins mediated through the Akt/GSK3β and MKK4/MKK7/JNKs signaling pathways[1].
Isoangustone A suppresses PI3-K, MKK4, and MKK7 kinase activities by directly binding in an ATP-competitive manner[1].
Isoangustone A (20 μM; 0.5-4 h) induces autophagy in colorectal cancer cells by activating AMPK signaling[2].
Isoangustone A (1-20 μM; 0-100 min) inhibits mitochondrial respiration[2].
Isoangustone A (15 μM; 6 h) induces SW480 cells apoptosis[2].
Isoangustone A (1-20 μΜ; 3 days) suppresses mesangial fibrosis and inflammation in human renal mesangial cells[3].

Cell Proliferation Assay[1]

Cell Line: SK-MEL-28
Concentration: 10 and 20 μM
Incubation Time: 48 and 72 h
Result: Inhibited proliferation in a dose- and time-dependent manner.

Cell Cycle Analysis[1]

Cell Line: SK-MEL-28
Concentration: 10 and 20 μM
Incubation Time: 48 h
Result: Caused cell cycle arrest at G1 phase.

Western Blot Analysis[1]

Cell Line: SK-MEL-28
Concentration: 10 and 20 μM
Incubation Time: 48 h
Result: Inhibited the expression of cyclin D1 and cyclin E. Suppressed phosphorylation of Rb in a dose-dependent manner. Inhibited the phosphorylation of Akt (Ser473, Thr308) and GSK3β (Ser9). Suppressed the phosphorylation of JNK1/2, but had no effect on ERK1/2 or p38.

Cell Autophagy Assay[2]

Cell Line: SW480 cells
Concentration: 20 μM
Incubation Time: 0.5, 2 and 4 h
Result: Deformed mitochondria, nondegradable cellular debris were all observable together with autophagic vacuoles in cells after 4 h.

Apoptosis Analysis[2]

Cell Line: SW480 cells
Concentration: 15 μM
Incubation Time: 6 h
Result: Induced elevation of apoptotic Annexin V+/PI- and Annexin V+/PI+ cell populations.
In Vivo

Isoangustone A (2 or 10 mg/kg; i.p.; daily for 35 days) significantly decreases tumor growth, volume, and weight of SK-MEL-28 xenografts in mice[1].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Animal Model: Male Balb/c nu/nu mice, SK-MEL-28 xenograft model[1]
Dosage: 2 or 10 mg/kg
Administration: Intraperitoneal injection, daily for 35 days
Result: Significantly suppressed tumor weight compared to the control group. Markedly inhibited the expression of proliferating cell nuclear antigen (PCNA). Decreased phosphorylation levels of Akt.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
