Vandortuzumab (DSTP-3086S Antibody; RG-7450 Antibody) is a humanized anti-STEAP1 IgG1 antibody and antimitotic agent that can be conjugated with MMAE (HY-15162) to form the antibody-drug conjugate (ADC) Vandortuzumab vedotin. Vandortuzumab vedotin specifically binds to STEAP1 and drives internalization of the complex, releasing the MMAE (HY-15162) payload intracellularly. After binding to tubulin, MMAE inhibits cell division and induces cell death. Vandortuzumab exhibits antitumor activity in preclinical xenograft models of prostate cancer and can be used for research related to metastatic castration-resistant prostate cancer (mCRPC).

ON1231320 is a highly specific polo like kinase 2 (PLK2) inhibitor with an IC₅₀ of 0.31 μM. ON1231320 blocks tumor cell cycle progression in the G2/M phase in mitosis, causing apoptotic cell death. ON1231320, an arylsulfonyl pyrido-pyrimidinone, has antitumor activity.

N-Boc-dolaproine ((2R,3R)-BOC-dolaproine) is the amino acid residue of the pentapeptide Dolastatin 10 (HY-15580). Dolastatin 10 inhibits tubulin polymerization and mitosis and has anticancer activity.

Vimentin-IN-1 is a FiVe1 derivative, an orally active and selective anticancer agent. FiVe1 binds type III intermediate filament protein vimentin (VIM), to induce hyperphosphorylation of Ser56, resulting selective disruption of mitosis and multinucleation in transformed VIM-expressing mesenchymal cancer cells. Vimentin-IN-1 shows better oral bioavailability and pharmacokinetic profiles than FiVe1.

FiVe1 is a vimentin (VIM) inhibitor. FiVe1 binds to the rod domain of VIM, causing metaphase VIM disassembly and hyperphosphorylation at Ser56, ultimately leading to mitotic catastrophe, multinucleation, and loss of stemness. FiVe1 has anticancer activity against soft tissue sarcomas. FiVe1 increases the sensitivity of ovarian cancer to Cisplatin (HY-17394). FiVe1 can be used for researches of mesenchymal cancers (including breast cancer and soft tissue sarcoma) and ovarian cancers.

FT709 is a potent and selective USP9X inhibitor, an IC₅₀ of 82 nM. USP9X has been linked with centrosome function, chromosome alignment during mitosis, EGF receptor degradation, chemo-sensitization, and circadian rhythms.

UMK57 is a MCAK activator and kinetochore-microtubule destabilizer. UMK57 enhances MCAK-dependent microtubule depolymerization, increases kinetochore-microtubule turnover, reduces chromosome mis-segregation and lagging chromosomes, and inhibits cancer cell proliferation. UMK57 triggers adaptive resistance in Aurora B cancer cells via reversible Aurora B signaling pathway alterations. UMK57 can be used for the research of solid tumors.

AG126 is a tyrosine kinase inhibitor, can inhibit the phosphorylation of ERK1 and ERK2 at 25-50 μM. AG126 can be used in meiosis, mitosis, and postmitotic research.

EDTA-AM (ethylenediaminetetraacetic acid, acetoxymethyl ester) is the membrane-permeant form of the metal chelator EDTA (HY-Y0682). Live cells passively load EDTA-AM by incubating with EDTA-AM. Once internalized, cytoplasmic esterase decomposes AM esters, releasing the active ligand EDTA, which isolates metal ions within the cell. EDTA-AM induces an arrest of mitotic progression and chromosome decondensation.

Litronesib (LY2523355) is a selective mitosis-specific kinesin Eg5 inhibitor, with antitumor activity.

HMN-176 is a stilbene derivative which inhibits mitosis, interfering with polo-like kinase-1 (plk1), without significant effect on tubulin polymerization.

Tubulysin A (TubA) is an anticancer and antiangiogenic agent with anti-microtubule, anti-mitosis and anti-proliferative activity against a variety of cancer cells with IC₅₀ values in the pmol range. It can induce apoptosis of cancer cells and has no effect on normal cells. Tubulysins are a group of potent cytotoxins consisting of nine members (A-I). Tubulysin A can synthesize ADC as ADC Cytotoxin.

AZD4877 is another isostere to Ispinesib (HY-50759)and also a kinesin spindle protein (Eg5) inhibitor with IC₅₀ of 2 nM.AZD4877 arrests cell mitosis, leads to the formation of the monopolar spindle phenotype and induces apoptosis. AZD4877 inhibits circulating peripheral blood mononuclear cells (PBMCs) and has anti-cancer activity.

Chiauranib has strongly anticancer effects.

Arecaidine propargyl ester hydrobromide is an agonist of M2 muscarinic acetylcholine receptors and has the activity of inhibiting tumor cell proliferation. The application of arecaidine propargyl ester hydrobromide has shown that it can reduce the number of ovarian cancer cells in vitro and induce apoptosis and the production of reactive oxygen species (ROS) at specific concentrations. Arecaidine propargyl ester hydrobromide can also arrest cells at the G2/M phase of the cell cycle and increase the percentage of abnormal mitosis. Arecaidine propargyl ester hydrobromide is more sensitizing to ovarian surface epithelial cells with higher M2 receptor levels than to cancer cells. Arecaidine propargyl ester hydrobromide exhibits the effect of lowering arterial blood pressure when interacting with the cardiovascular system in a natural physiological state, indicating its potential pharmacological application.
