aurora b (human)

Hesperadin 是 Aurora A 和 B 的 ATP 竞争性吲哚酮抑制剂，抑制 Aurora B 的 IC50值为250nM。它通过阻断核分裂和胞质分裂而抑制布鲁氏锥虫的生长。它也是一种广谱流感抗病毒剂。

PLX-4720 是一种有效且选择性的 B-Raf (V600E) 抑制剂，旨在阻断致癌B-Raf的ATP结合位点，IC50为 13 nM。

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.

Binucleine 2 is an isoform-specific and ATP-competitive inhibitor of Drosophila Aurora B kinase (Ki = 0.36 μM), a kinase involved in cell division. It is specific for Drosophila Aurora B kinase, inhibiting it in a dose-dependent manner, with minimal inhibition of human or X. laevis Aurora B kinases at concentrations up to 100 μM. Binucleine 2 induces mitotic and cytokinesis defects in Drosophila Kc167 cells. It prevents Drosophila S2 cells from assembling a contractile ring during cell division when used at a concentration of 40 μM but does not affect ring ingression, suggesting that Aurora B kinase activity is not required for that step.

BI847325是MEK 和极光激酶 (AK)的一种选择性双重抑制剂， 对人类MEK2和AK-C 的IC50值分别为4和15 nM。

BPR1K653 is a potent Aurora kinase inhibitor with potential anticancder activity. BPR1K653 specifically inhibited the activity of Aurora-A and Aurora-B kinase at low nano-molar concentrations in vitro. BPR1K653 was potent in targeting a variety of cancer cell lines regardless of the tissue origin, p53 status, or expression of MDR1. At the cellular level, BPR1K653 induced endo-replication and subsequent apoptosis in both MDR1-negative and MDR1-positive cancer cells. Importantly, it showed potent activity against the growth of xenograft tumors of the human cervical carcinoma KB and KB-derived MDR1-positive KB-VIN10 cells in nude mice. Finally, BPR1K653 also exhibited favorable pharmacokinetic properties in rats., BPR1K653 is a promising anti-cancer compound that has potential for the management of various malignancies, particularly for patients with MDR1-related drug resistance after prolonged chemotherapeutic treatments.

TY-011是一种激活DNA损伤和细胞凋亡（Apoptosis）的Aurora A B激酶抑制剂。通过诱导不正常的微管-着丝粒附着，TY-011能有效抑制人胃癌细胞增殖，其对人胃癌细胞系的IC50值范围为0.11-4.49 μM。该化合物主要用于胃癌领域的科学研究。
