Rotenone is an odorless, colorless,

jicama vine, and in the roots of several other members of the Fabaceae. It was the first-described member of the family of chemical compounds known as rotenoids
.

Discovery

The earliest written record of the now-known rotenone-containing plants used for killing leaf-eating

Min Nan Chinese: lôo-tîn) translated into Japanese rōten (ローテン).[6] By 1930, nicouline and rotenone were established to be chemically the same.[7]

Uses

Rotenone is used as a pesticide, insecticide, and as a nonselective piscicide (fish killer).[8] Rotenone has historically been used by indigenous peoples to catch fish. Typically, rotenone-containing plants in the legume family, Fabaceae, are crushed and introduced into a body of water, and as rotenone interferes with cellular respiration, the affected fish rise to the surface in an attempt to gulp air, where they are more easily caught.

In modern times it is frequently used as a tool to remove alien fish species,[9] as it has a relatively short half-life (days) and is gone from rivers in the course of days and from lakes within a few months, depending on (seasonal) stirring, organic content, availability of sunlight and temperature.[10] Rotenone has been used by government agencies to kill fish in rivers and lakes in the United States since 1952,[11] and in Canada[12] and Norway[13] since the 1980s. It is less frequently used in EU countries, due to strict regulations, but has seen some use in selected countries such as the UK (Topmouth gudgeon), Sweden (pike and pumpkinseed), Spain (Topmouth gudgeon, Gambusia) and Hungary (Prussian carp).

Rotenone decays through metabolites and its final product is reduced to water and carbon dioxide.[10] Furthermore, its use is more benign for the environment (as compared to other piscicides) as most species are seen to recolonize aquatic systems within weeks to a year after application.[14][15][16] Thus, it has also seen some use in other field studies in the marine environment needing only small quantities. Small-scale sampling with rotenone is used by fish researchers studying the biodiversity of marine fishes to collect cryptic, or hidden, fishes, which represent an important component of shoreline fish communities, since it has only minor and transient environmental side effects.[17]

It is commercialized as

cubé, tuba, or derris, in single preparation or in synergistic combination with other insecticides.[18] In the United States and Canada, all uses of rotenone except as a piscicide are being phased out.[19][20] It is currently banned in the United States for any use in organic farming.[21] In the UK, rotenone insecticides (sold under the trade name Derris) were banned for sale in 2009.[22]

Rotenone is also used in powdered form to treat

chickens, livestock, and pet
animals.

In agriculture it is also unselective in action and kills

potato beetles, cucumber beetles, flea beetles, cabbage worms, raspberry beetles, and asparagus beetles, as well as most other arthropods. It biodegrades rapidly in soil, with 90% degraded after 1–3 months at 20 °C (68 °F) and three times faster at 30 °C (86 °F).[23]

Mechanism of action

Rotenone works by interfering with the

CoQ, creating a back-up of electrons within the mitochondrial matrix. Cellular oxygen is reduced to the radical, creating reactive oxygen species, which can damage DNA and other components of the mitochondria.[25]

Rotenone also inhibits microtubule assembly.[26]

Presence in plants

Rotenone is produced by extraction from the roots and stems of several tropical and subtropical plant species, especially those belonging to the genera Lonchocarpus and Derris.

Some of the plants containing rotenone:

Human toxicity

Rotenone is classified by the

erythrocytes in vitro.[33]

The lowest lethal dose for a child is not known, but death occurred in a 3.5-year-old child who had ingested 40 mg/kg rotenone solution.[34] Human deaths from rotenone poisoning are rare because its irritating action causes vomiting.[35] Deliberate ingestion of rotenone can be fatal.[34]

The compound decomposes when exposed to sunlight and usually has an activity of six days in the environment.[36] It oxidizes to rotenolone, which is about an order of magnitude less toxic than rotenone. In water, the rate of decomposition depends upon several factors, including temperature, pH, water hardness and sunlight. The half-life in natural waters ranges from half a day at 24 °C to 3.5 days at 0 °C.[37]

A 2018 study, which examined the effects of rotenone administration on cell cultures that mimicked properties of developing brains, found that rotenone may be a developmental

dopaminergic neurons, consistent with prior findings.[38]

Parkinson's disease

In 2000, injecting rotenone into rats was reported to cause the development of symptoms similar to those of

HSE
procedure in modern application of the chemical.

Studies with primary cultures of rat

neurons,[42] and it is these neurons in the substantia nigra that die in Parkinson's disease. Another study has also described toxic action of rotenone at low concentrations (5 nM) in dopaminergic neurons from acute rat brain slices.[43]
This toxicity was exacerbated by an additional cell stressor – elevated intracellular calcium concentration – adding support to the 'multiple hit hypothesis' of dopaminergic neuron death.

The

lipophilic and can cross the blood–brain barrier
.

In 2010, a study was published detailing the progression of Parkinson's-like symptoms in mice following chronic intragastric ingestion of low doses of rotenone. The concentrations in the central nervous system were below detectable limits, yet still induced PD pathology.[46]

Notable administrations

In 1992,

Southern and Central Florida.[47]

In September 2010, Oregon Department of Fish and Wildlife officials used rotenone to kill an established population of invasive goldfish present in eastern Oregon's Mann Lake, with the intention of not disrupting the lake's native Lahontan cutthroat trout population. Rotenone successfully achieved these aims, killing between 179,000–197,000 goldfish and fathead minnows, and only three trout.[48]

Beginning May 1, 2006, Panguitch Lake, a reservoir in the southeastern portion of the U.S. state of Utah, was treated with rotenone, to potentially eradicate and control the invasive population of Utah chub, which were probably introduced accidentally by anglers who used them as live bait. The lake was restocked with 20,000 rainbow trout in 2006; as of 2016, the lake's fish population has recovered.

In 2012, rotenone was used to kill all remaining fish in Stormy Lake (Alaska) due to invasive pike destroying native species, which were reintroduced once the treatment was concluded.[49]

In 2014, rotenone was used to kill all remaining fish in San Francisco's Mountain Lake, which is located in Mountain Lake Park, in order to rid it of invasive species introduced since the migration of European settlers to the region.[50]

Rotenone is used in biomedical research to study the oxygen consumption rate of cells, usually in combination with antimycin A (an electron transport chain Complex III inhibitor), oligomycin (an ATP synthase inhibitor) and FCCP (a mitochondrial uncoupler).[51]

Deactivation

Rotenone can be deactivated in water with the use of potassium permanganate to lower toxicity to acceptable levels.[52]
