1. US20020058679 - Heat shock factor activity inhibitor

A disease treatment is provided by controlling the expression of a protein induced by a heat shock factor.

The novel compound benzo-1,3-dioxole provides an inhibitor of HSF activity or an inhibitor of inducing the production of a protein regulated by HSF, which inhibits the activity of a heat shock factor, a transcriptional regulatory factor, thereby in turn inhibiting transcription of a structural gene having a heat shock element sequence in the gene region for transcriptional regulation into RNA, and thus inhibiting translation of the gene into a protein, and resulting in inhibition of inducing production of RNA or protein encoded by the gene. It also provides a drug for treating or preventing cancer through thermotherapy and a drug for treating or preventing stress diseases such as depression.
