| Targets |
L-Valinol does not have a defined pharmacological target of its own, as it is a chiral building block used in synthesis. It is used as a reagent for the synthesis of simple 1,3-thiazolidine-2-thione derivatives with fungicidal activity. It is also used in clinical trials to synthesize small molecule inhibitors of MDM2-p53 protein-protein interaction (MDM2 inhibitors) for the treatment of cancer.
|
|---|---|
| ln Vitro |
In vitro, L-valinol is primarily used as a chemical reagent and synthetic intermediate. It reacts with aldehydes and nitriles to form imines and oxazolines, respectively, for asymmetric synthesis. It is used for the preparation of 4-isopropyloxazolidinones. As a chiral amino alcohol, it is a valuable building block for the synthesis of enantiomerically pure pharmaceutical compounds and other bioactive molecules.
|
| ln Vivo |
In vivo data for L-valinol itself are not available, as the compound is not intended for direct in vivo administration. Rather, it is a precursor used in the synthesis of drug candidates such as MDM2-p53 inhibitors that are subsequently evaluated in animal models. The compound's in vivo relevance is indirect, through the biological activities of the final pharmaceutical compounds derived from its chiral scaffold.
|
| Enzyme Assay |
For in vitro chemical synthesis, L-valinol is used as a chiral building block for the preparation of various compounds. Standard protocols involve reacting L-valinol with aldehydes to form imines (Schiff bases) or with nitriles to form oxazolines. The compound can also be used in the synthesis of 1,3-thiazolidine-2-thione derivatives. The amino alcohol functionality enables a wide range of transformations while maintaining stereochemical integrity.
|
| Cell Assay |
For in vitro cell-based experiments, L-valinol is used as an intermediate in the synthesis of compounds that are tested in cell viability, proliferation, and cytotoxicity assays. The compound itself is not typically evaluated in cell-based assays. Standard cell culture protocols for test compounds synthesized from this intermediate involve dissolving the final product in DMSO and diluting to working concentrations in appropriate cell culture medium.
|
| Animal Protocol |
In vivo animal studies using L-valinol are conducted on the final drug compounds synthesized from it, not on the intermediate itself. For MDM2-p53 inhibitors derived from this building block, efficacy studies would typically be performed in mouse xenograft models of cancer. Standard in vivo protocols involve administration to rodents via oral gavage or intraperitoneal injection, with measurement of tumor volume over time.
|
| ADME/Pharmacokinetics |
Pharmacokinetic properties of L-valinol as a standalone compound are not characterized in the literature. The compound has a molecular weight of 103.17 g/mol, which is very favorable for oral bioavailability. The amino alcohol functionality may influence water solubility and metabolic conjugation. The compound's chiral nature is important for the synthesis of enantiomerically pure drug candidates. Empirical pharmacokinetic data are not available for this intermediate compound.
|
| Toxicity/Toxicokinetics |
L-Valinol is a research chemical and should be handled with appropriate laboratory safety precautions. As an amino alcohol, it may cause skin and eye irritation. The compound is for research use only and not for human therapeutic or diagnostic applications. Specific LD₅₀ values, acute toxicity classifications, and chronic toxicity data are not available in the public literature. Standard safety practices include the use of personal protective equipment and working in a fume hood.
|
| Additional Infomation |
L-Valinol ((S)-2-Amino-3-methyl-butanol) (CAS 2026-48-4) is primarily a research-grade chiral building block, not an FDA-approved pharmaceutical drug. Its primary applications are in asymmetric synthesis for the preparation of enantiomerically pure compounds, in the synthesis of MDM2-p53 inhibitors for cancer research, and in the preparation of fungicidal agents. No clinical trials or approved therapeutic indications exist for this compound as a drug.

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).
