JNJ-7706621 is a potentaurora kinaseinhibitor, and also inhibitsCDK1andCDK2, withIC₅₀s of 9 nM, 3 nM, 11 nM, and 15 nM forCDK1,CDK2,aurora-Aandaurora-B, respectively^[1][2][3].

JNJ-7706621 shows antiproliferative activity against various human tumor cells with IC₅₀s of 284, 254, and 447 nM for HeLa, HCT116, and A375, respectively^[1]. JNJ-7706621 inhibits other centrosomal proteins such as TOG, Nek2, and TACC3 in early mitotic phase, but does not prevent localization of Aurora A to the spindle poles. Treatment of nocodazole-synchronized cells with JNJ-7706621 can override mitotic arrest by preventing spindle checkpoint signaling, resulting in failure of chromosome alignment and segregation^[2]. JNJ-7706621 shows inhibition of Aurora-A and Aurora-B but has no activity at the highest concentration tested on the Plk1 or Wee1 serine/threonine kinases. JNJ-7706621 also shows potent growth inhibition in vitro on all human cancer cell types with IC₅₀values ranging from 112 to 514 nM^[3]. JNJ-7706621 suspensions inhibits cell viability of HeLa cells with IC₅₀s of 2.1 and 0.9 μg/mL at 24 and 48 h. The IC₅₀of the JNJ-7706621-loaded nanoparticles are 35 and 2.7 μg/mL and the IC₅₀of the JNJ-7706621-loaded micelles are 6.3 and 1.6 μg/mL^[4].

JNJ-7706621 (100 and 125 mg/kg) is efficacious in a human tumor xenograft model under intermittent dosing regimens^[3]. JNJ-7706621 (100 mg/kg, i.p.) exhibits 95% tumor growth inhibition in A375 (human melanoma) tumor xenograft model^[1]. JNJ-7706621-loaded micelles inhibit tumor growth, and delay the tumor growth more efficiently than the control JNJ-7706621 suspension^[4].
