JNJ-26481585 exhibits broad spectrum antiproliferative activity in solid and hematologic cancer cell lines, such as all lung, breast, colon, prostate, brain, and ovarian tumor cell lines, with IC50 ranging from 3.1-246 nM, which is more potent than vorinostat, R306465, panobinostat, CRA-24781, or mocetinostat in various human cancer cell lines tested. A recent study shows that JNJ-26481585 promotes myeloma cell death at low nanomolar concentrations by resulting in Mcl-1 depletion and Hsp72 induction.

In an HDAC1-responsive A2780 ovarian tumor screening model, JNJ-26481585 dosing at its maximal tolerated dose (10 mg/kg i.p. and 40 mg/kg p.o.) for 3 days leads to an HDAC1-regulated fluorescence , which predicts tumor growth inhibition. Furthermore, JNJ-26481585 also shows more potent inhibitory effects on the growth of C170HM2 colorectal liver metastases than 5-fluorouracil/Leucovorin.
