Background

Custirsen is a benzopyran with potential antineoplastic activity. Custirsen acts as a selective estrogen receptor modulator (SERM), inhibiting the proliferation of estrogen-sensitive breast cancer cells. This agent also inhibits growth and induces apoptosis of glioblastoma cells via a mechanism independent of estrogen receptor-related mechanisms. Custirsen is also being investigated in the treatment of primary brain tumors.

Pharmacodynamics

CC-8490, a new anti-cancer compound from Celgene's proprietary class of benzopyrans, being evaluated as a potential therapy for brain cancer. The National Cancer Institute also reports applications in breast cancer related to potential antineoplastic activity. CC-8490 acts as a selective estrogen receptor modulator (SERM), inhibiting the proliferation of estrogen-sensitive breast cancer cells. This agent also inhibits growth and induces apoptosis of glioblastoma cells via a mechanism independent of estrogen receptor-related mechanisms.

Mechanism of action

CC-8490 acts as a selective estrogen receptor modulator (SERM), inhibiting the proliferation of estrogen-sensitive breast cancer cells. This agent also inhibits growth and induces apoptosis of glioblastoma cells via a mechanism independent of estrogen receptor-related mechanisms.

Preliminary results in studies regarding the mechanism of action in brain cancer suggest that C-8490 surpresses nuclear factor (NF)-KB with its target genes IEX-3, SOD2, IL6, and IL8.
