Metabolite Identification
Common NameMetaflumizone
DescriptionMetaflumizone belongs to the class of organic compounds known as stilbenes. These are organic compounds containing a 1,2-diphenylethylene moiety. Stilbenes (C6-C2-C6 ) are derived from the common phenylpropene (C6-C3) skeleton building block. The introduction of one or more hydroxyl groups to a phenyl ring lead to stilbenoids. Metaflumizone is an extremely weak basic (essentially neutral) compound (based on its pKa). However, in a cross comparison with other veterinary flea control substances, Metaflumizone was not shown to result in a significant reduction in the number of engorged adult female Culex mosquitoes. Therefore, its usefulness as a heartworm control treatment is likely to be insignificant when compared with comparable treatments such as selamectin that do impact the mosquito disease vector. Metaflumizone is a semicarbazone insecticide indicated for the veterinary treatment of fleas and ticks, marketed under the brand name ProMeris. In 2011, Pfizer Animal Care decided to cease production of the drug based on findings which linked its use to an elevated incidence of the autoimmune disorder pemphigus foliaceus. The metaflumizone-only formulation is waterproof and typically remain effective for 30–45 days in a cutaneous application at the base of the neck. Metaflumizone works by blocking sodium channels in target insects, resulting in flaccid paralysis. Metaflumizone is chemically similar to pyrazoline sodium channel blocker insecticides (SCBIs) discovered at Philips-Duphar in the early 1970s, but is less dangerous to mammals than earlier compounds. Metaflumizone blocks sodium channels by binding selectively to the slow-inactivated state, which is characteristic of the SCBIs. This compound has been identified in human blood as reported by (PMID: 31557052 ). Metaflumizone is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Metaflumizone is part of the human exposome. The exposome can be defined as the collection of all the exposures of an individual in a lifetime and how those exposures relate to health. An individual's exposure begins before birth and includes insults from environmental and occupational sources.
