| Targets |
L-Homoserine lactone hydrochloride does not have a defined pharmacological target of its own, as it is a synthetic intermediate. However, it is used in the synthesis of bacterial quorum-sensing signaling molecules, particularly N-(3-oxododecanoyl)-L-homoserine lactone, which act as immune modulators. The compound's lactone ring and amino group provide handles for derivatization in the synthesis of biologically active compounds.

|---|---|
| ln Vitro |
In vitro, L-Homoserine lactone hydrochloride is primarily used as a chemical reagent and synthetic intermediate. It is used in the synthesis of organoselenium chemistry intermediates and analogs of bacterial quorum-sensing signaling molecules. The compound's hydrochloride form enhances its solubility in aqueous solutions, making it ideal for various in vitro experiments. It is a key intermediate in the synthesis of the chiral herbicide L-glufosinate.

| ln Vivo |
In vivo activity data for L-Homoserine lactone hydrochloride 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 quorum-sensing signaling molecules that are subsequently evaluated as immune modulators in vivo. The compound's in vivo relevance is indirect, through the biological activities of the final compounds derived from it.
|
| Enzyme Assay |
For in vitro enzyme/receptor binding studies, L-Homoserine lactone hydrochloride is not typically evaluated as a test compound itself. Instead, it serves as a reagent for the synthesis of test compounds. The compound's properties include a molecular weight of 137.57 g/mol and a molecular formula of C₄H₈ClNO₂. The lactone ring and amino group provide handles for further derivatization in medicinal chemistry and quorum sensing research.

| Cell Assay |
For in vitro cell-based experiments, L-Homoserine lactone hydrochloride is used as an intermediate in the synthesis of compounds that are tested in cell-based 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 or aqueous buffer and diluting to working concentrations in appropriate cell culture medium.
|
| Animal Protocol |
In vivo animal studies using L-Homoserine lactone hydrochloride are conducted on the final compounds synthesized from it, such as quorum-sensing signaling molecules evaluated as immune modulators. Standard in vivo protocols involve administration to rodents via appropriate routes with pharmacokinetic and immunomodulatory endpoints. Specific protocols for the intermediate compound are not documented.
|
| ADME/Pharmacokinetics |
Pharmacokinetic properties of L-Homoserine lactone hydrochloride as a standalone compound are not characterized in the literature. The compound has a molecular weight of 137.57 g/mol, which is within the favorable range for oral bioavailability. The hydrochloride salt form enhances aqueous solubility. The compound should be stored as powder at -20°C for up to 3 years or in solvent at -80°C for up to 1 year.
|
| Toxicity/Toxicokinetics |
L-Homoserine lactone hydrochloride is a research chemical and should be handled with appropriate laboratory safety precautions. As a lactone and amine salt, it may pose risks of skin and eye irritation. 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 (gloves, safety goggles, lab coat) and working in a well-ventilated area.

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).

*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.
