Eribulin (B1939) is a nonpaclitaxel microtubule kinetic inhibitor with anticancer activity that inhibits polymerization of microtubule protein subunits by preventing lengthening and shortening of microtubules during cell division.Eribulin is used in the study of metastatic breast cancer and solid tumors.

Methotrexate (WR19039) is a folate analog, an inhibitor of the dihydrofolate reductase DHFR. Methotrexate has antimetabolic, antitumor, and immunosuppressive activities, and is commonly used in rheumatoid arthritis and various tumors.

Calicheamicin (Calicheamicin γ1) is an antitumor antibiotic and is a DNA synthesis inhibitor. It also is a cytotoxic agent that causes double-strand DNA breaks.

SN-38 (NK012) is the active metabolite of Irinotecan, a DNA topoisomerase I (Topo I) inhibitor, which inhibits DNA and RNA synthesis (IC50=0.077 1.3 μM). SN-38 has antitumor activity and induces autophagy.

Exatecan (DX-8951f) is a DNA topoisomerase I (TOP1) inhibitor with an IC50 value of 2.2 μM (0.975 μg mL).Exatecan has antitumor activity and may be used in cancer research.

Monomethyl auristatin E (MMAE) (MMAE), an antimitotic agent, inhibits cell division by blocking the polymerization of tubulin and also has inhibition of antibody-drug conjugates (ADCs) activity.

FL118-14-Propanol is a cytotoxic camptothecin derivative, a potential topoisomerase I inhibitor with potential antitumor activity, which can be used in the synthesis of ADC compounds.

Mertansine is a tubulin inhibitor and an antibody-conjugable maytansinoid alkaloid. The IC50 of Mertansine against HCT-15 and A431 cells is 0.750 and 0.04nM.

Fluticasone propionate (CCI-187881), derived from fluticasone used to remedy asthma and allergic rhinitis, is a high affinity, selective GR (glucocorticoid receptor) agonist.

Camptothecin (CPT) belongs to the alkaloid group of natural products and is a specific DNA topoisomerase I (Topo I) inhibitor (IC50=679 nM) with specificity. Camptothecin has antitumor activity and induces apoptosis.

10-Methoxycamptothecin, a natural bioactive derivative of camptothecin (CPT) isolated from *Camptotheca acuminata*, exhibits potent anti-cancer properties.

17-AEP-GA is an HSP90 antagonist, a potent inhibitor of glioblastoma cell proliferation, survival, migration, and invasion, and a toxic component of antibody-coupled activated molecules (ADCs), which can be used to study glioblastomas.

Thailanstatin A is an ultra-potent inhibitor of eukaryotic RNA splicing (IC50 = 650 nM). It inhibits multiple cancer cell lines via non-covalent binding to the SF3b subunit of the U2 snRNA subcomplex of the spliceosome, displaying low-nM to sub-nM IC50s. Thailanstatin A, as a payload for ADCs, is conjugated to the lysines on trastuzumab, yielding linker-less ADC.

MMAF (MonoMethyl auristatin F), an antimitotic agent, inhibits cell division by blocking the polymerization of tubulin.

Dolastatin 10 (DLS 10) is a potent peptide with antimitotic properties, effectively inhibiting tubulin polymerization.

7-Epi 10-desacetyl paclitaxel (10-Deacetyl-7-epipaclitaxel) shows IC50 values of 0.085 nM, against HeLa cells.
