Ergot definition is - the black or dark purple sclerotium of fungi (genus Claviceps) that occurs as a club-shaped body replacing the seed of a grass (such as rye); also : a fungus bearing ergots. The ergot alkaloids owe their pharmacological activity to their ability to act at a-adrenergic, dopaminergic and serotonergic receptors. The relationship of the general alkaloid structure to those of noradrenaline, dopamine, and 5-hydroxytryptamine (5-HT, serotonin) is shown in Figure 105. The pharmacological response may be complex.
