2D Structure
Description

Hyoscyamine is a plant toxin found in certain plants of the Solanaceae family, including henbane (Hyoscyamus niger), mandrake (Mandragora officinarum), jimsonweed (Datura stramonium), and deadly nightshade (Atropa belladonna). It is used as a drug to provide symptomatic relief to various gastrointestinal disorders including spasms, peptic ulcers, irritable bowel syndrome, pancreatitis, colic and cystitis. It has also been used to relieve some heart problems, control some of the symptoms of Parkinson's disease, as well as for control of respiratory secretions in palliative care.(L1255)

Targets

General Function:
Transmitter-gated ion channel activity
Specific Function:
The glycine receptor is a neurotransmitter-gated ion channel. Binding of glycine to its receptor increases the chloride conductance and thus produces hyperpolarization (inhibition of neuronal firing).

General Function:
Guanyl-nucleotide exchange factor activity
Specific Function:
The muscarinic acetylcholine receptor mediates various cellular responses, including inhibition of adenylate cyclase, breakdown of phosphoinositides and modulation of potassium channels through the action of G proteins. Primary transducing effect is inhibition of adenylate cyclase.
Gene Name:
CHRM4
Uniprot ID:

Molecular Weight:
53048.65 Da
Mechanism of Action:
Hyoscyamine is an anticholinergic, specifically an antimuscarinic, and works by blocking the action of acetylcholine at parasympathetic sites in smooth muscle, secretory glands, and the central nervous system.

General Function:
G-protein coupled acetylcholine receptor activity
Specific Function:
The muscarinic acetylcholine receptor mediates various cellular responses, including inhibition of adenylate cyclase, breakdown of phosphoinositides and modulation of potassium channels through the action of G proteins. Primary transducing effect is adenylate cyclase inhibition. Signaling promotes phospholipase C activity, leading to the release of inositol trisphosphate (IP3); this then triggers calcium ion release into the cytosol.
