Description

Elaiophylin (Azalomycin B; Gopalamicin; Efomycin E) is an autophagy inhibitor, exerts antitumor activity as a single agent in ovarian cancer cells[1].

IC50 & Target

Autophagy[1]

In Vitro

Elaiophylin-mediated autophagy inhibition and lysosomal dysfunction affect ovarian cancer cell survival during hypoxia. Exposure to Elaiophylin (0.025-0.5 μM; 24 hours) causes a significant increase in ovarian cancer SKOV3 cell death in hypoxia conditions[1].
In both the SKOV3 and A2780 cell lines, Elaiophylin (0.25, 0.5, 0.75 μM; 24 hours) treatment leads to significant activation of cleaved CASP9/caspase-9 and PARP1 and downregulation of BIRC5/survivin in a concentration-dependent manner[1].

Cell Viability Assay[1]

Cell Line: Ovarian cancer SKOV3 cells.
Concentration: 0.025, 0.05, 0.1, 0.2, 0.5 μM
Incubation Time: 24 hours
Result: Caused a significant increase in ovarian cancer SKOV3 cells death in hypoxia conditions.

Western Blot Analysis[1]

Cell Line: Ovarian cancer SKOV3 cells; A2780 cells
Concentration: 0.25, 0.5, 0.75 μM
Incubation Time: 24 hours
Result: Treatment led to significant activation of cleaved CASP9/caspase-9 and PARP1 and downregulation of BIRC5/survivin in a concentration-dependent manner.
In Vivo

Treatment with 2 mg/kg Elaiophylin (given i.p. every 2 days for 21 days; in BALB/C athymic mice) significantly suppresses ovarian cancer SKOV3 cells growth compared with DMSO treatment, resulting in a 72% decrease in the average daily tumor growth rate compared with DMSO treatment [1].
Lower doses of Elaiophylin as a single agent exert significant antitumor activity, while higher doses lead to intestinal toxicity. Administration of a lower dose (2 mg/kg) of Elaiophylin as a single agent achieves a significant antitumor effect without toxicity in an orthotopic ovarian cancer model with metastasis. Toxic reactions are observed only in the 8 mg/kg group[1].

Animal Model: 4-wk-old BALB/C athymic mice with ovarian cancer SKOV3 cells[1]
Dosage: 1 or 2 mg/kg
Administration: Given i.p. every 2 days for 21 days
Result: Treatment with 2 mg/kg significantly suppressed ovarian cancer SKOV3 cells growth compared with DMSO treatment.
