| Targets |
Cyclopropylboronic acid does not have a specific biological target itself. It is a synthetic intermediate used to prepare bioactive molecules, including EGFR kinase inhibitors. Compound 25, synthesized from cyclopropylboronic acid, targets EGFR mutants (EGFR Δ19del/T790M/C797S) and exhibits antiproliferative effects. The cyclopropyl group is often used in drug design to increase activity, fix conformation, and improve pharmacokinetic properties and water solubility.
|
|---|---|
| ln Vitro |
Cyclopropylboronic acid is a chemical intermediate and does not possess intrinsic in vitro biological activity. Its value lies in its utility for synthesizing bioactive molecules, including EGFR kinase inhibitors. The compound is used to introduce cyclopropyl groups into drug candidates, which can enhance activity, fix conformation, and improve pharmacokinetic properties. It is not directly assayed for biological effects.
|
| ln Vivo |
This compound is not a pharmacologically active agent and does not have intrinsic in vivo activity. Its applications in vivo are limited to its use as a synthetic intermediate for producing drug candidates that are subsequently evaluated in animal models. EGFR kinase inhibitors synthesized from this intermediate may be evaluated in tumor-bearing mice for anticancer efficacy. The compound itself is not administered to animals as a test compound.
|
| Enzyme Assay |
Cyclopropylboronic acid is not typically used in cell-free enzyme/receptor binding assays. Its role in drug discovery is as a synthetic building block. For compounds synthesized using this reagent, typical binding assays may be performed. These involve incubating the test compound with purified enzymes or receptors in buffered solutions, with binding affinity measured by SPR, ITC, or fluorescence-based methods.
|
| Cell Assay |
Cell-based assays are not directly performed on cyclopropylboronic acid due to its lack of biological activity. However, drug candidates synthesized from this intermediate, such as EGFR kinase inhibitors, are tested in cellular systems. For EGFR inhibitors, cancer cell lines with EGFR mutations (e.g., NSCLC cells with Δ19del/T790M/C797S) are cultured and treated with the synthesized compound. Cell viability (MTT), apoptosis, and EGFR phosphorylation are assessed over 24–72 hours.
|
| Animal Protocol |
In vivo studies with cyclopropylboronic acid derivatives may involve administration to tumor-bearing mice via oral gavage or intravenous injection. For EGFR kinase inhibitors, tumor growth inhibition, survival, body weight, and pharmacokinetic parameters are monitored. Tissue distribution and toxicity are assessed by histopathology. All procedures follow institutional animal care guidelines.
|
| ADME/Pharmacokinetics |
Cyclopropylboronic acid is a synthetic chemical reagent and is not subject to pharmacokinetic evaluation as a drug. Its physicochemical properties include a molecular weight of 85.9 g/mol and a molecular formula of C3H7BO2. The compound is stable under normal storage conditions and is available in high purity (≥96%). The cyclopropyl group is valued in drug design for introducing conformational constraints and improving pharmacokinetic properties.
|
| Toxicity/Toxicokinetics |
The toxicological profile of cyclopropylboronic acid has not been extensively characterized. As a boronic acid, it may cause skin, eye, and respiratory tract irritation. Standard laboratory safety precautions should be observed, including the use of personal protective equipment (gloves, goggles, lab coat) and adequate ventilation. Ingestion or inhalation should be avoided. Appropriate first-aid measures should be in place.
|
| Additional Infomation |
Cyclopropylboronic acid is not a drug but a valuable chemical intermediate and building block for medicinal chemistry. It is used to synthesize EGFR kinase inhibitors with activity against mutant EGFR cells. The cyclopropyl group is often used in drug design to increase activity, fix conformation, and improve pharmacokinetic properties and water solubility. It serves as a key building block in the development of bioactive molecules, agrochemicals, and pharmaceutical intermediates. It is not approved for clinical use.

Injection Formulations
Injection Formulation 1: DMSO : Tween 80： Saline = 10 : 5 : 85 (i.e. 100 μL DMSO stock solution → 50 μL Tween 80 → 850 μL Saline)(e.g. IP/IV/IM/SC) *Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH ₂ O to obtain a clear solution. Injection Formulation 2: DMSO : PEG300 ：Tween 80 : Saline = 10 : 40 : 5 : 45 (i.e. 100 μL DMSO → 400 μLPEG300 → 50 μL Tween 80 → 450 μL Saline) Injection Formulation 3: DMSO : Corn oil = 10 : 90 (i.e. 100 μL DMSO → 900 μL Corn oil) Example: Take the Injection Formulation 3 (DMSO : Corn oil = 10 : 90) as an example, if 1 mL of 2.5 mg/mL working solution is to be prepared, you can take 100 μL 25 mg/mL DMSO stock solution and add to 900 μL corn oil, mix well to obtain a clear or suspension solution (2.5 mg/mL, ready for use in animals).
