Sodium acetate C-11 (C-11 acetate) Injection is a radiopharmaceutical commonly used for clinical studies with positron emission tomography (PET). It is used as a PET radiotracer for imaging cancer cells via incorporation into intracellular phosphatidylcholine membrane microdomains in cancer cells. Positron emission tomography using carbon-11 acetate (AC-PET) may help find local or distant metastases from prostate cancer. C-11 acetate is taken up in proportion to fatty acid synthesis. It is also taken up proportionally to myocardial blood flow, and therefore myocardial oxygen consumption. In rodents, there is clearance from all organs except the pancreas within one hour. Tumor uptake was clearly visible in 30 minutes. In humans, more than 80% of tracer is cleared from normal tissues within 20 minutes.It is taken up in cancer within the prostate and prostate cancer metastases, however, it has been reported that increased uptake can be seen in hyperplastic and benign prostate tissues. No urinary excretion is seen. No toxic effects have been demonstrated. The ongoing clinical trial NCT01530269 is studying how this imaging test may help influence the choice and extent of initial treatments, and subsequent treatments of prostate cancer.

Acid Orange 20 is an azodye. Used for wool, silk fiber dyeing, etc. Also used in leather dyeing and indicator.

Quaternium-24 (octyl decyl dimethyl ammonium chloride) is an organic compound classified as quaternary ammonium salt. It is used as a disinfectant, sanitizer and fungicide in cleaning solutions and pre-moistened wipes. It is also used as a surfactant in cosmetics and pharmaceuticals.

Octenidine dihydrochloride is a cationic surfactant, with antimicrobial activity against Gram-positive and Gram-negative bacteria. Octenidine approved as a medicinal substance in several European countries and used for skin antisepsis in combination with aliphatic alcohols, e.g. propan-1-ol and propan-2-ol, or with detergents such as antiseptic soap. Octenidine is also used for antisepsis on wounds and mucosa either as a single substance, as an approved combination of Octenidine and phenoxyethanol. Octenidine is virtually not absorbed via the skin or mucous membranes. Because Octenidine is only approved and used topically and is virtually not absorbed, no systemic effects are to be expected. Therefore, no further pharmacokinetic studies or studies on behalf of metabolism have been conducted. Octenidine is easy and safe to handle, chemically stable, not inflammable, without resistance development and low toxicity to man and the environment alike. Its popularity among therapists and wound care specialists is based on good clinical results, easy and pain-free application and local tolerance. Beside readily available combinations with phenoxyethanol, mouth rinses, and vaginal applications, semi-fluid preparations and dressings are described.
