| Targets |
N-Boc-dolaproine dicyclohexylamine itself, as an amino acid residue of Dolastatin 10, does not directly act on a specific target. Its activity is derived from the antitumor mechanism of the complete pentapeptide Dolastatin 10. Dolastatin 10 exerts its antitumor activity by binding to tubulin, inhibiting tubulin polymerization and mitosis. The structure of Dolastatin 10, composed of amino acids including dolaproine, has been demonstrated to possess potent tubulin inhibition and cytotoxicity, forming the structural basis for the widely used auristatin-class payloads in ADC drugs.

| ln Vitro |
N-Boc-dolaproine dicyclohexylamine, as a synthetic building block of Dolastatin 10, has not been reported to possess direct in vitro cellular activity. However, Dolastatin 10 and auristatin analogs containing the dolaproine residue demonstrate extremely potent antiproliferative activity in vitro. Dolastatin 10 exerts its effects by inhibiting tubulin polymerization, and its derived auristatin-class compounds (e.g., MMAE, MMAF) are among the most widely used cytotoxic payloads in ADC drugs today, exhibiting picomolar to nanomolar cytotoxicity against various tumor cell lines.
|
| ln Vivo |
As an amino acid component of the complete pentapeptide Dolastatin 10, its pharmacological activity derives from the final constructed antitumor molecule. Dolastatin 10 and its auristatin derivatives demonstrate significant tumor growth inhibition in animal xenograft models. ADC drugs containing dolaproine structural units have demonstrated in vivo antitumor efficacy in both preclinical and clinical studies.
|
| Enzyme Assay |
N-Boc-dolaproine dicyclohexylamine itself, as a synthetic intermediate, is not directly used in enzyme/receptor binding assays. This compound is primarily used as a raw material for introducing the dolaproine amino acid residue in solid-phase or liquid-phase peptide synthesis. In relevant applications, the compound is first subjected to Boc deprotection, then coupled to the growing peptide chain via condensation reactions. Its purity can be analyzed by HPLC, and its structure can be characterized by NMR and mass spectrometry.
|
| Cell Assay |
N-Boc-dolaproine dicyclohexylamine, as a synthetic intermediate, is not used in direct in vitro cell assays. Cytotoxicity evaluation of complete Dolastatin 10 or auristatin-class compounds containing the dolaproine structure typically follows this protocol: Exponentially growing tumor cells (e.g., human leukemia cells or solid tumor cell lines) are seeded into 96-well culture plates at densities of 5,000-10,000 cells/well, cultured overnight, then treated with various concentrations of the test compound (0.001-100 nM) for 72-96 hours. Cell viability is assessed using MTT or CellTiter-Glo luminescent assays, and GI₅₀ values are calculated.
|
| Animal Protocol |
N-Boc-dolaproine dicyclohexylamine, as a synthetic intermediate, is not used in in vivo animal experiments. This compound must undergo multi-step synthesis to assemble into the complete active molecule before being used for in vivo pharmacodynamic studies. In vivo experiments for complete Dolastatin 10 or auristatin-class ADC drugs typically use 6-8-week-old female nude mice subcutaneously inoculated with human tumor cell lines (5×10⁶ cells/100 μL PBS). When tumor volumes reach approximately 100-150 mm³, animals are randomly assigned to treatment groups, with tumor volume and body weight measured 2-3 times weekly to calculate tumor inhibition rates.
|
| ADME/Pharmacokinetics |
N-Boc-dolaproine dicyclohexylamine is a synthetic intermediate and is not directly used for pharmacokinetic studies. The pharmacokinetics of auristatin-class ADC drugs containing dolaproine units have been reported in preclinical and clinical studies. Taking MMAE as an example, following intravenous administration in tumor-bearing mice, the half-life is approximately 2.5 hours, plasma clearance is approximately 60 mL/h, tissue distribution shows the highest concentration in the liver, metabolism is primarily mediated by CYP3A4, and excretion occurs via feces and urine. This compound itself is not used directly as a drug, and its pharmacokinetic parameters do not possess independent pharmacological significance.
|
| Toxicity/Toxicokinetics |
N-Boc-dolaproine dicyclohexylamine, as a synthetic intermediate, has not been systematically studied for its toxicological profile. This product is explicitly intended for research use only and is not for human therapeutic applications. The toxicity of auristatin-class payloads derived from it has been evaluated in relevant ADC drug studies, primarily manifesting as dose-limiting hematological toxicities (such as neutropenia and thrombocytopenia) along with some gastrointestinal reactions. The presence of the dicyclohexylamine salt indicates that this compound may have some irritant properties, and standard laboratory safety practices should be followed during handling.
