ML216 (CID-49852229) is a small molecule inhibitor of BLM helicase with an IC50 of 1.8 μM, demonstrating 28-fold selectivity against the related helicases RECQ1, RECQ5, and E. coli UvrD (IC50s > 50 μM).

ZK-Thiazolidinone, also known as TAL, is an ATP-competitive inhibitor of PLK1. In vitro, ZK-Thiazolidinone counteracts the role of Plk1 in previously established functions, notably, sister chromatid separation, centrosome maturation, and bipolar spindle assembly. In vivo, ZK-Thiazolidinone selectively inhibits PLK1 and causes a prometaphase-like mitotic (G2–M) arrest. ZK-Thiazolidinone inhibits human PLK1 (IC50, 19± 12 nM) and various human and mouse tumor cell lines (IC50, 0.2–1.3 μM). ZK-Thiazolidinone impairs centrosome maturation.

Degrader targeting mutant FKBP12F36V fusion proteins. Comprises a ligand selective for F36V single-point mutated FKBP12, a linker and a von Hippel-Lindau (VHL)-binding ligand. Induces potent and selective degradation of FKBP12F36V fusion proteins in vitro and in vivo. Selectively degrades FKBP12F36V-EWS FLI fusion proteins and inhibits cell proliferation in FKBP12F36V-EWS FLI-expressing Ewing sarcoma cells. Hydrochloride salt (Cat.No. 7374) available; suitable for in vivo use. Negative control dTAGV-1-NEG (Cat. No. 6915) also available. FKBP12F36V can be expressed as a fusion with a target protein of interest using genome engineering techniques, via transgene expression or CRISPR-mediated locus-specific knock-in. Custom knock-in cell lines for the dTAG and aTAG platforms are available from our sister brand R&D Systems. Email TPD@bio-techne.com to enquire. Plasmid vectors for the lentiviral expression and CRISPR-mediated knock-in of FKBP12F36V are available from Addgene.

AZD4877 is a synthetic kinesin spindle protein (KSP) inhibitor with potential antineoplastic activity. KSP inhibitor AZD4877 selectively inhibits microtubule motor protein KSP (also called kinesin-5 or Eg5), which may result in the inhibition of mitotic spindle assembly; activation of the spindle assembly checkpoint; induction of cell cycle arrest during the mitotic phase; and cell death in tumor cells that are actively dividing. Because KSP is not involved in postmitotic processes, such as neuronal transport, this agent may be less likely to cause the peripheral neuropathy often associated with the tubulin-targeting agents. Eg5 is essential for the formation of bipolar spindles and the proper segregation of sister chromatids during mitosis.

gamma-Fagarine possesses moderate levels of anti-HCV activities with IC50 values being 20.4 ± 0.4 ug ml, respectively. It has sister chromatid exchanges (SCEs)-inducing activity
