| Targets |
As a labeled antibiotic, Clindamycin-13C,d3 targets the same bacterial ribosomal subunit as unlabeled Clindamycin. Clindamycin binds to the 50S ribosomal subunit and inhibits bacterial protein synthesis by preventing peptide bond formation. The compound is classified as an Isotope-Labeled Compound.

| ln Vitro |
Drug compounds have included stable heavy isotopes of carbon, hydrogen, and other elements, mostly as quantitative tracers while the drugs were being developed. Because deuteration may have an effect on a drug's pharmacokinetics and metabolic properties, it is a cause for concern [1].
Clindamycin-13C,d3 is used in vitro as a tracer to study the antibacterial activity and pharmacokinetics of Clindamycin. The compound does not exhibit intrinsic pharmacological activity beyond that of Clindamycin but serves as a quantitative tool for studying antibiotic uptake, distribution, and metabolism in bacterial and mammalian cells. |
| ln Vivo |
In vivo, Clindamycin-13C,d3 is used in pharmacokinetic and pharmacodynamic studies to trace the distribution and metabolism of Clindamycin in animal models. The dual isotope label (¹³C and d₃) allows for precise quantification of the antibiotic and its metabolites in plasma and tissues using mass spectrometry.
|
| Enzyme Assay |
As an internal standard, Clindamycin-13C,d3 is used in analytical assays such as LC-MS/MS. Typical protocols involve spiking the labeled compound into biological samples prior to extraction and analysis. The labeled compound co-elutes with the unlabeled Clindamycin but is detected at a different mass-to-charge ratio, allowing for precise quantification and correction for matrix effects.
|
| Cell Assay |
In vitro cell-based experiments using Clindamycin-13C,d3 involve treating bacterial or mammalian cells with the compound and analyzing its uptake and metabolism by mass spectrometry. The compound can be used to study antibiotic resistance mechanisms and the pharmacokinetics of Clindamycin in various cell types.
|
| Animal Protocol |
In vivo animal studies using Clindamycin-13C,d3 involve administering the compound to rodents via oral gavage or intravenous injection. Blood samples are collected at various time points, and the concentration of the labeled compound is measured by mass spectrometry. Tissue distribution and metabolic profiling can also be performed.
|
| ADME/Pharmacokinetics |
Clindamycin-13C,d3 exhibits pharmacokinetic properties similar to those of unlabeled Clindamycin. Clindamycin is rapidly absorbed after oral administration and has good tissue penetration. It is metabolized in the liver and excreted primarily in urine and bile. The isotope labels provide distinct mass shifts for analytical detection.
|
| Toxicity/Toxicokinetics |
Clindamycin-13C,d3 is considered safe for research use at typical concentrations. Unlabeled Clindamycin has a well-established safety profile but can cause adverse effects such as gastrointestinal disturbances and pseudomembranous colitis. As a stable isotope-labeled compound, it is not intended for therapeutic use and is handled under standard laboratory safety practices.

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).
