kb NB 142-70 is a potent PKD inhibitor, with IC₅₀s of 28.3, 58.7 and 53.2 nM for PKD1, PKD2, and PKD3, respectively. kb NB 142-70 also has antitumor activity.

kb NB 142-70 is a potent PKD inhibitor, with IC₅₀s of 28.3, 58.7 and 53.2 nM for PKD1, PKD2, and PKD3, respectively. kb NB 142-70 also inhibits Ser⁹¹⁶ phosphorylation of PKD1 (IC₅₀, 2.2 ± 0.6 μM) in LNCaP cells. Moreover, kb NB 142-70 is cytotoxic against PC3 cells with an EC₅₀ of 8.025 μM^[1]. kb NB 142-70 (0-5 μM) concentration-dependently prevents ANG II-induced phosphorylation of HDAC4 at Ser²⁴⁶ and Ser⁶³², HDAC5 at Ser²⁵⁹ and Ser⁴⁹⁸, and HDAC7 at Ser¹⁵⁵ in IEC-18 cells. In addition, kb NB 142-70 (3.5 μM) also suppresses HDAC4, HDAC5, and HDAC7 phosphorylation in IEC-18 cells stimulated with ANG II for 0-240 min or with vasopressin, lysophosphatidic acid (LPA), or phorbol 12,13-dibutyrate (PDBu)^[2].

Briefly, PC3 cells are treated with kb NB 142-70 at 10 μM concentration for 48 h, and then fixed in 70% ice-cold ethanol overnight and labeled with propidium iodide. The labeled cells are analyzed using a FACScan Benchtop Cytometer^[1].
