Apicidin is a cyclic peptide antibiotic with broad spectrum antiparasitic and antiprotozoan activity. Apicidin, a histone deacetylase inhibitor, is anti-angiogenic and induces apoptosis. A potent, cell permeable inhibitor of histone deacetylase (IC50 = 700 pM for parasitic histone deacetylase). Inhibits HeLa cell proliferation (IC50 = 50 100 nM) and induces the transcriptional activation of p21 (WAF1) in a reversible manner. Also prevents H-ras-induced invasive phenotype of MCF-10A cells possibly by down regulating MMP-2 in a reversible manner. Apicidin has antiproliferative activity on HeLa cells accompanied by cell arrest at the G1 phase. Apicidin induces selective changes in the expression of p21 and gelsolin.

Suitable for use as a histone deacetylase inhibitor. Other applications have not been tested
