L-Hyoscyamine sulfate (Levsin Sulfate) is the sulfate salt of a belladonna alkaloid derivative and the levorotatory form of racemic atropine isolated from the plants Hyoscyamus niger or Atropa belladonna, which exhibits anticholinergic activity. Hyoscyamine functions as a non-selective, competitive antagonist of muscarinic receptors, thereby inhibiting the parasympathetic activities of acetylcholine on the salivary, bronchial, and sweat glands, as well as the eye, heart, bladder, and gastrointestinal tract. These inhibitory effects cause a decrease in saliva, bronchial mucus, gastric juices, and sweat. Furthermore, its inhibitory action on smooth muscle prevents bladder contraction and decreases gastrointestinal motility.

(S)-(-)-Phenylethanol ((-)-Methyl phenyl carbinol) exists as a solid, soluble (in water), and a very weakly acidic compound (based on its pKa). (S)-(-)-Phenylethanol has been detected in multiple biofluids, such as feces and saliva. Within the cell, (S)-(-)-Phenylethanol is primarily located in the cytoplasm.

L-Hyoscyamine (Daturine) functions as a non-selective, competitive antagonist of muscarinic receptors, thereby inhibiting the parasympathetic activities of acetylcholine on the salivary, bronchial, and sweat glands, as well as the eye, heart, bladder, and gastrointestinal tract. Hyoscyamine is a belladonna alkaloid derivative and the levorotatory form of racemic atropine isolated from the plants Hyoscyamus niger or Atropa belladonna, which exhibits anticholinergic activity. These inhibitory effects cause a decrease in saliva, bronchial mucus, gastric juices, and sweat. Furthermore, its inhibitory action on smooth muscle prevents bladder contraction and decreases gastrointestinal motility.

p-Toluic Acid (4-Methylbenzoic acid) belongs to the class of organic compounds known as benzoic acids. 4-Methylbenzoic acid has been primarily detected in saliva. Within the cell, 4-methylbenzoic acid is primarily located in the cytoplasm.

(R)-pyrrolidine-2-carboxylic acid (D-Proline) is an isomer of the naturally occurring amino acid, L-Proline. D-amino acids have been found in relatively high abundance in human plasma and saliva. These amino acids may be of bacterial origin, but there is also evidence that they are endogenously produced through amino acid racemase activity.

N-Acetylleucine belongs to the class of organic compounds known as leucine and derivatives. Leucine and derivatives are compounds containing leucine or a derivative thereof resulting from reaction of leucine at the amino group or the carboxy group, or fro
