Answers
Answer:
explanation:
Plants of the family Solanaceae contain various anticholinergic tropane alkaloids, such as scopolamine, atropine, and hyoscyamine. Physostigmine is one of only a few drugs that can be used as an antidote for anticholinergic poisoning.
The solanaceous alkaloids, represented by (-)- hyoscyamine, atropine, and scopolamine (hyoscine) are the forerunners of the class of antimuscarinic drugs. ... All of the solanaceous alkaloids are esters of the bicyclic aminoalcohol.
It can be viewed as a derivative of a carboxylic acid RC(=O)OH with the hydroxyl group –OH replaced by an amine group –NR′R″; or, equivalently, an acyl (alkanoyl) group RC(=O)– joined to an amine group. ... The core –C(=O)N= of amides is called the amide group (specifically, carboxamide group).
