Temephos-d₁₂ is the deuterium labeled Temephos. Temephos (Temefos) is an orally active, blood-brain barrier-permeable organophosphate insecticide and AChE inhibitor. By irreversibly inhibiting AChE to induce cholinergic overactivation, Temephos effectively blocks larval development of Aedes aegypti (yellow fever mosquito) and Aedes albopictus (Asian tiger mosquito), and is commonly used in studies related to Dengue Virus, Zika Virus and other relevant pathogens. Temephos exhibits genotoxicity and neurodevelopmental toxicity, and may also cause liver injury, reproductive system abnormalities and cholinergic poisoning symptoms in mammals. Temephos tends to accumulate in adipose tissues and aquatic organisms, and is excreted via feces after metabolism through oxidation and hydrolysis. Note that CYP-mediated metabolic detoxification may reduce the actual larvicidal efficacy of Temephos against some mosquito species. Temephos can be used in research related to dengue fever, Zika virus disease, chikungunya and dracunculiasis.

Clindamycin (hydrochloride monohydrate) (Standard) is the analytical standard of Clindamycin (hydrochloride monohydrate). This product is intended for research and analytical applications. Clindamycin hydrochloride monohydrate is an oral protein synthesis inhibitory agent that has the ability to suppress the expression of virulence factors in Staphylococcus aureus at sub-inhibitory concentrations (sub-MICs). Clindamycin hydrochloride monohydrate resistance results from enzymatic methylation of the antibiotic binding site in the 50S ribosomal subunit (23S rRNA). Clindamycin hydrochloride monohydrate decreases the production of Panton-Valentine leucocidin (PVL), toxic-shock-staphylococcal toxin (TSST-1) or alpha-haemolysin (Hla).
