Ro-3306^New

RO-3306 is an ATP-competitive, and selective CDK1 inhibitor with K_i of 20 nM, >15-fold selectivity against a diverse panel of human kinases. RO-3306 enhances p53-mediated Bax activation and mitochondrial apoptosis.

ML141^New

ML141 (CID-2950007) is demonstrated to be a potent, selective and reversible non-competitive inhibitor of Cdc42 GTPase suitable for in vitro assays, with IC50 of 200 nM and selectivity against other members of the Rho family of GTPases (Rac1, Rab2, Rab7). ML141 is associated with an increase in p38 activation and may induce p38-dependent apoptosis/senescence. ML141 also protects neuroblastoma cells from metformin-induced apoptosis.

Salirasib^New

Salirasib (Farnesylthiosalicylic acid, FTS) is a potent competitive prenylated protein methyltransferase (PPMTase) inhibitor with K_i of 2.6 μM, which inhibits Ras methylation. Salirasib exerts antitumor effects and induces autophagy. Phase 2.

Alisertib (MLN8237)

Alisertib (MLN8237) is a selective Aurora A inhibitor with IC50 of 1.2 nM in a cell-free assay. It has >200-fold higher selectivity for Aurora A than Aurora B. Alisertib induces cell cycle arrest, apoptosis and autophagy. Phase 3.

Barasertib (AZD1152-HQPA)

Defosbarasertib (AZD1152-HQPA, AZD2811, INH-34, Barasertib-HQPA) is a highly selective Aurora B inhibitor with IC50 of 0.37 nM in a cell-free assay, ~3700 fold more selective for Aurora B over Aurora A. Phase 1.

Tozasertib

Tozasertib (VX-680, MK-0457) is a pan-Aurora inhibitor, mostly against Aurora A with K_iapp of 0.6 nM in a cell-free assay, less potent towards Aurora B/Aurora C and 100-fold more selective for Aurora A than 55 other kinases. The only exceptions are Fms-related tyrosine kinase-3 (FLT-3) and BCR-ABL tyrosine kinase, which are inhibited by the Tozasertib with both Ki of 30 nM. Tozasertib induces apoptosis and autophagy. Phase 2.

Danusertib (PHA-739358)

Danusertib (PHA-739358) is an Aurora kinase inhibitor for Aurora A/B/C with IC50 of 13 nM/79 nM/61 nM in cell-free assays, modestly potent to Abl, TrkA, c-RET and FGFR1, and less potent to Lck, VEGFR2/3, c-Kit, CDK2, etc. Danusertib induces apoptosis, cell cycle arrest, and autophagy. Phase 2.

ZM 447439

ZM 447439 is a selective and ATP-competitive inhibitor for Aurora A and Aurora B with IC50 of 110 nM and 130 nM, respectively. It is more than 8-fold selective for Aurora A/B than MEK1, Src, Lck and has little effect against CDK1/2/4, Plk1, Chk1, etc.

MLN8054

MLN8054 is a potent and selective inhibitor of Aurora A with IC50 of 4 nM in Sf9 insect cell. It is more than 40-fold selective for Aurora A than Aurora B. Phase 1.

MK-5108 (VX-689)

MK-5108 (VX-689) is a highly selective Aurora A inhibitor with IC50 of 0.064 nM in a cell-free assay and is 220- and 190-fold more selective for Aurora A than Aurora B/C, while it inhibits TrkA with less than 100-fold selectivity. MK-5108 (VX-689) induces autophagy. Phase 1.
