WitrynaPicloram is a pyridinemonocarboxylic acid that is pyridine-2-carboxylic acid which is substituted by a chloro group at positions 3,5 and 6, and by an amino group at position 4. It is a systemic herbicide used to control deeply rooted herbaceous weeds and woody plants in rights-of-way, forestry, range lands, pastures, and small grain crops. WitrynaStructure-activity relationship studies with TCDD and three dioxin congeners revealed a rank order for their potency in the inhibition of glucose transport as follows: TCDD > 1,2,3,7,8-PCDD > 1,2,4,7,8-PCDD > 2,7-DCDD. Such a rank order is consistent with the previously determined biological activity of TCDD and the other dioxin congeners. crypto factory mining
