Pindone is a vitamin K antagonist, with delayed inhibition of prothrombin formation, and repeated doses have a cumulative effect on blood coagulation. Death in animals from chronic exposure is due to multiple internal hemorrhage.
These compounds depress the hepatic synthesis of vitamin K1-dependent clotting factors (II, VII, IX, X) by inhibiting the vitamin K1 2,3-reductase enzyme in the vitamin K1-epoxide cycle. /Anticoagulant rodenticides/
Both 4-hydroxycoumarin derivatives and indandiones (also known as oral anticoagulants) are antagonists of vitamin K. Their use as rodenticides is based on the inhibition of the vitamin K-dependent step in the synthesis of a number of blood coagulation factors. The vitamin K-dependent proteins ...in the coagulation cascade... are the procoagulant factors II (prothrombin), VII (proconvertin), IX (Christmas factor) and X (Stuart-Prower factor), and the coagulation-inhibiting proteins C and S. All these proteins are synthesized in the liver. Before they are released into the circulation the various precursor proteins undergo substantial (intracellular) post-translational modification. Vitamin K functions as a co-enzyme in one of these modifications, namely the carboxylation at well-defined positions of 10-12 glutamate residues into gamma-carboxyglutamate (Gla). The presence of these Gla residues is essential for the procoagulant activity of the various coagulations factors. Vitamin K hydroquinone (KH2) is the active co-enzyme, and its oxidation to vitamin K 2,3-epoxide (KO) provides the energy required for the carboxylation reaction. The epoxide is than recycled in two reduction steps mediated by the enzyme KO reductase... . The latter enzyme is the target enzyme for coumarin anticoagulants. Their blocking of the KO reductase leads to a rapid exhaustion of the supply of KH2, and thus to an effective prevention of the formation of Gla residues. This leads to an accumulation of non-carboxylated coagulation factor precursors in the liver. In some cases these precursors are processed further without being carboxylated, and (depending on the species) may appear in the circulation. At that stage the under-carboxylated proteins are designated as descarboxy coagulation factors. Normal coagulation factors circulate in the form of zymogens, which can only participate in the coagulation cascade after being activated by limited proteolytic degradation. Descarboxy coagulation factors have no procoagulant activity (i.e. they cannot be activated) and neither they can be converted into the active zymogens by vitamin K action. Whereas in anticoagulated humans high levels of circulating descarboxy coagulation factors are detectable, these levels are negligible in warfarin-treated rats and mice. /Anticoagulant rodenticides/

As the federal pesticide law FIFRA directs, EPA is conducting a comprehensive review of older pesticides to consider their health and environmental effects and make decisions about their future use. Under this pesticide reregistration program, EPA examines health and safety data for pesticide active ingredients initially registered before November 1, 1984, and determines whether they are eligible for reregistration. In addition, all pesticides must meet the new safety standard of the Food Quality Protection Act of 1996. Pesticides for which EPA had not issued Registration Standards prior to the effective date of FIFRA, as amended in 1988, were divided into three lists based upon their potential for human exposure and other factors, with List B containing pesticides of greater concern and List D pesticides of less concern. 2-Pivalyl-1,3-indandione is found on List B. Case No: 2810; Pesticide type: Rodenticide; Case Status: OPP has made a decision that products containing the pesticide are not eligible for reregistration.; Active ingredient (AI): 2-Pivalyl-1,3-indandione; Data Call-in (DCI) Date(s): 06/17/91; AI Status: OPP has completed a Reregistration Eligibility Decision (RED) document for the case/AI.

Personal protection: particulate filter respirator adapted to the airborne concentration of the substance. Do NOT let this chemical enter the environment. Sweep spilled substance into covered containers. If appropriate, moisten first to prevent dusting.
SRP: The scientific literature for the use of contact lenses in industry is conflicting. The benefit or detrimental effects of wearing contact lenses depend not only upon the substance, but also on factors including the form of the substance, characteristics and duration of the exposure, the uses of other eye protection equipment, and the hygiene of the lenses. However, there may be individual substances whose irritating or corrosive properties are such that the wearing of contact lenses would be harmful to the eye. In those specific cases, contact lenses should not be worn. In any event, the usual eye protection equipment should be worn even when contact lenses are in place.

TERRESTRIAL FATE: Based on a classification scheme(1), an estimated Koc value of 900(SRC), determined from a water solubility of 18 mg/l(2) and a regression-derived equation(3), indicates that pindone is expected to have low mobility in soil(SRC). Volatilization of pindone from moist soil surfaces is not expected to be an important fate process(SRC) given an estimated Henry's Law constant of 9.3X10-12 atm-cu m/mole(SRC), using a fragment constant estimation method(4). Pindone is not expected to volatilize from dry soil surfaces(SRC) based upon an estimated vapor pressure of 8.4X10-6 mm Hg(SRC), determined from a fragment constant method(5).
AQUATIC FATE: Based on a classification scheme(1), an estimated Koc value of 900(SRC), determined from a water solubility of 18 mg/l(2) and a regression-derived equation(3), indicates that pindone is expected to adsorb to suspended solids and sediment(SRC). Volatilization from water surfaces is not expected(3) based upon an estimated Henry's Law constant of 9.3X10-12 atm-cu m/mole(SRC), developed using a fragment constant estimation method(4). According to a classification scheme(5), an estimated BCF of 120(SRC), from its water solubility(2) and a regression-derived equation(6), suggests the potential for bioconcentration in aquatic organisms is high(SRC).
ATMOSPHERIC FATE: According to a model of gas/particle partitioning of semivolatile organic compounds in the atmosphere(1), pindone, which has an estimated vapor pressure of 8.4X10-6 mm Hg at 25 °C(SRC), determined from a fragment constant method(2), will exist in both the vapor and particulate phases in the ambient atmosphere. Vapor-phase pindone is degraded in the atmosphere by reaction with photochemically-produced hydroxyl radicals(SRC); the half-life for this reaction in air is estimated to be 6 days(SRC), calculated from its rate constant of 2.9X10-12 cu cm/molecule-sec at 25 °C(SRC) that was derived using a structure estimation method(3). Particulate-phase pindone may be removed from the air by wet and dry deposition(SRC).
The substance can be absorbed into the body by ingestion.
inhalation, ingestion
/BIRDS and MAMMALS/ The sensitivity of a number of avian species to the rabbit poison pindone was investigated using increase of prothrombin time (PT) as an index of poisoning. Daily dose levels of pindone were 0.25 mg kg-1 for eagles, 4.0 mg kg-1 for magpies and 5.0 mg kg-1 for pigeons, parrots and ducks. Considerable species variation in response was observed, and within each species there was considerable individual variation in response to pindone. The PTs of magpies and ducks increased to approximately twice baseline levels. Significant elevations (4- to 7-fold) occurred in parrots, pigeons and eagles. Clinical symptoms were observed in only one species, the wedge-tailed eagle. Results of our dosing trials indicate that all species tested are theoretically at risk of pindone poisoning, although the risk to some species is minimized by factors such as population size, food availability and bait placement.

The substance is very toxic to aquatic organisms. This substance may be hazardous to the environment. Special attention should be given to birds and mammals. This substance does enter the environment under normal use. Great care, however, should be taken to avoid any additional release, for example through inappropriate disposal.
The Koc of pindone is estimated as 900(SRC), using a water solubility of 18 mg/l(1) and a regression-derived equation(2). According to a classification scheme(3), this estimated Koc value suggests that pindone is expected to have low mobility in soil.
/HUMAN EXPOSURE STUDIES/ Acute clinical effects depend on the site of hemorrhage & include hemoptysis, hematuria, gastrointestinal bleeding, abdominal or back pain (retroperitoneal hemorrhage), hemarthrosis, epistaxis, cerebrovascular accidents, & multiple ecchymotic lesions. /Anticoagulant rodenticides/
/HUMAN EXPOSURE STUDIES/ The usual mode of death is gastrointestinal hemorrhage. /Anticoagulant rodenticides/
/HUMAN EXPOSURE STUDIES/ /Indandione deriv/ ... can produce hemorrhagic accidents if they are absorbed in large or repeated quantities, or by persons with natural or acquired sensitivity. /indandione deriv/
/HUMAN EXPOSURE STUDIES/ If accidental ingestion occurs, the symptoms and signs are anticipated to be similar to those caused by warfarin, which may include hematuria, spontaneous hematomas on the arms and legs, epistaxis, bleeding from the lips, punctate hemorrhages from mucous membranes, abdominal and back pain, vomiting, blood in the feces, petechial rash, and abnormal blood findings, such as increased prothrombin time and blood plasma, blood in urine and feces, and hypochromic and microcytic anemia.
