Application

CI-994 has been used:
  • as an histone deacetylase (HDAC) inhibitor to treat SUM229 and DT22 cells to study its effects
  • as an HDAC inhibitor for screening in SPEL cells
  • to study its effects on human myeloid and erythroid progenitors

Biochem/physiol Actions

CI-994 is the acetylated derivative form of the original compound Dinaline (PD 104 208). It is an oral cytostatic drug with impressive differential activity against leukemic cells & normal stem-cells. It is used for combination therapy for selected tumors including non-small cell lung, pancreatic, breast, and colorectal cancers. It acts as a histone deacetylase inhibitor. CI-994 blocks cells in the G1-S phase of the cell cycle. The 16 kDa phosphoprotein is confined to the nuclear compartment. Loss of the 16-kDa nuclear phosphoprotein appears to be a direct effect of CI-994 treatment and that the inhibition of this phosphoprotein may play a critical role in the mechanism of action of CI-994.

CI-994, an oral histone deacetylase inhibitor, has antineoplastic activity and synergism with gemcitabine preclinically. This randomized phase II trial explored whether CI-994 plus gemcitabine improves overall survival, objective response, duration of response, time to treatment failure and change in quality
