tubulin inhibitor-6

Tubulin inhibitor 6 (iHAP1) is an inhibitor of tubulin and a potent inhibitor of multiple cancer cell lines.

Tubulin polymerization-IN-63 (compound 6) is an inhibitor of tubulin polymerization. It exhibits an IC50 value of 0.29 μM against MES-SA cells, making it suitable for use in cancer research.

Tubulin polymerization-IN-75 (Compound 6) is an inhibitor of tubulin polymerization, with an IC50 value of 30 μM. It effectively suppresses the proliferation of cancer cells Huh7 and 293T, demonstrating IC50 values of 14.3 μM and 13.8 μM, respectively.

PARP1-IN-6, a dual-function inhibitor, targets both tubulin and PARP-1, demonstrating inhibitory concentration (IC50) values of 0.94 μM for tubulin and 0.48 μM for PARP-1.

AZD 1152 is an orally bioavailable prodrug of AZD 1152-HQPA, a selective inhibitor of Aurora kinase B (IC50= 0.36 nM).1AZD 1152 is converted to AZD 1152-HQPA in plasma. Inhibition of Aurora B results in disruption of spindle checkpoint functions and chromosome alignment, resulting in inhibition of cytokinesis followed by apoptosis.2,3AZD 1152 inhibits tumor xenograft growthin vivo.4,5 1.Mortlock, A.A., Foote, K.M., Heron, N.M., et al.Discovery, synthesis, and in vivo activity of a new class of pyrazoloquinazolines as selective inhibitors of aurora B kinaseJ.

HDAC3 6-IN-2 (compound 15) is a dual inhibitor targeting HDAC6 and HDAC3, with IC50 values of 0.368 μM and 0.635 μM, respectively. This compound demonstrates antitumor effects by inducing apoptosis in cancer cells, reducing HDAC6 and HDAC3 levels, and increasing acetylation of H3 and α-tubulin [1].

Tubulin polymerization-IN-6 (compound 5f) is a potent tubulin polymerization inhibitor with an IC50 of 1.09 μM. It inhibits cell migration and tube formation, exhibits anti-angiogenic properties, and effectively hinders tumor growth in HT29 xenograft Balb c nude mice [1].
