| Targets |
Chloro(methyl)(phenyl)silane does not have a biological target. It is a highly reactive organosilicon compound. Its primary interactions are chemical, not biological. The Si-Cl and Si-H bonds are readily hydrolyzed by water, releasing hydrochloric acid. It will react with any nucleophile, including those found in biomolecules like amino acids and DNA, but this is non-specific and destructive. It is not designed for therapeutic use.
|
|---|---|
| ln Vitro |
No in vitro biological activity is reported. This compound is highly reactive and would be expected to be extremely cytotoxic to any cell in culture due to rapid hydrolysis and non-specific alkylation. An in vitro assay would involve diluting the compound into the culture medium, where it would decompose immediately. It is not meant for use in cell-based assays. It does not have an IC50 in the traditional sense.
|
| ln Vivo |
No in vivo activity is reported. The compound would be corrosive upon contact with tissues and would be rapidly hydrolyzed in the body, producing hydrochloric acid and a silanol. It is not intended for in vivo administration. As an impurity, it would be controlled at very low levels due to its high reactivity and potential to form genotoxic alkylating species.
|
| Enzyme Assay |
General in vitro reactivity assay: The compound's reactivity can be assessed by adding it to water or aqueous buffer at 25degC and monitoring the pH drop or the formation of the hydrolysis product by GC-MS. A standard cell viability assay is not relevant, but an MTT assay on HepG2 cells would show an IC50 < 1 uM due to non-specific toxicity.
|
| Cell Assay |
Not applicable. An in vitro cell assay is not routinely performed for such a reactive chemical intermediate. If necessary, the compound would be added to cells in a non-aqueous carrier (e.g., DMSO) and immediately diluted into the aqueous culture medium, leading to rapid hydrolysis and cell death. This would only serve to confirm its non-specific chemical reactivity and extreme cytotoxicity.
|
| Animal Protocol |
General in vivo animal protocol for impurity qualification: Dissolve the compound in an anhydrous, non-aqueous vehicle (e.g., corn oil). Administer to male SD rats (n=5 per group) by oral gavage at very low doses (0, 0.1, 0.5, 2 mg/kg) for 14 days. Monitor clinical signs, especially gastrointestinal tract irritation. At higher doses, severe GI ulceration and bleeding would be expected. The NOAEL is expected to be < 0.1 mg/kg.
|
| ADME/Pharmacokinetics |
This compound is highly reactive and unstable in an aqueous environment. Upon exposure to water (e.g., in the GI tract or blood), it will be rapidly and completely hydrolyzed to methyl(phenyl)silanol and hydrochloric acid. The resulting silanol may further condense. Any PK data is irrelevant as the parent compound will not survive long enough to be absorbed intact. The primary toxicokinetic consideration is the local corrosive effect of HCl.
|
| Toxicity/Toxicokinetics |
Chloro(methyl)(phenyl)silane is a corrosive and reactive chemical. The chloro and hydrosilane groups are structural alerts for genotoxicity due to their ability to directly alkylate DNA or generate reactive species. It must be considered a potential genotoxic impurity (PGI) and should be strictly controlled to very low ppm levels (e.g., 1.5 ug/day) per ICH M7 guidelines. It is a skin and eye irritant/corrosive.

Note: Listed below are some common formulations that may be used to formulate products with low water solubility (e.g. < 1 mg/mL), you may test these formulations using a minute amount of products to avoid loss of samples.
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).
