Warning label on a tube of rat poison containing bromadiolone on a dike of the Scheldt river in Steendorp, Belgium. Bromadiolone is a potent anticoagulant rodenticide.It is a second-generation 4-hydroxycoumarin derivative and vitamin K antagonist, often called a "super-warfarin" for its added potency and tendency to accumulate in the liver of the poisoned organism.
The second-generation vitamin K antagonist agents, used only in this fashion as poisons (because their duration of action is too long to be used as pharmaceuticals) include: coumatetralyl; difenacoum; flocoumafen; bromadiolone; tioclomarol; brodifacoum ("d-CON" etc.)
However, the main excitable cell is the neuron, which also has the simplest mechanism for the action potential. [citation needed] Neurons are electrically excitable cells composed, in general, of one or more dendrites, a single soma, a single axon and one or more axon terminals. Dendrites are cellular projections whose primary function is to ...
Brodifacoum is a 4-hydroxycoumarin anticoagulant, with a similar mode of action to its historical predecessors dicoumarol and warfarin.However, due to very high potency and long duration of action (elimination half-life of 20 – 130 days), it is characterised as a "second-generation" or "superwarfarin" anticoagulant.
Bromethalin was discovered in the early 1980s through an approach to find replacement rodenticides for first-generation anticoagulants, especially to be useful against rodents that had become resistant to Warfarin-type anticoagulant poisons.

A mechanism of action of a chemical could be "binding to DNA" while its broader mode of action would be "transcriptional regulation". [3] However, there is no clear consensus and the term mode of action is also often used, especially in the study of pesticides, to describe molecular mechanisms such as action on specific nuclear receptors or ...
In some literature articles, the terms "mechanism of action" and "mode of action" are used interchangeably, typically referring to the way in which the drug interacts and produces a medical effect. However, in actuality, a mode of action describes functional or anatomical changes, at the cellular level, resulting from the exposure of a living ...
