1-deoxysphingosine (m-18:1(4e))

1-Deoxysphingosine (m18:1(4E)) is an atypical sphingolipid that contains a double bond at the 4E native position and is formed when serine palmitoyltransferase condenses palmitoyl-CoA with alanine instead of serine during sphingolipid synthesis.1,2 Plasma levels of 1-deoxysphingosine (m18:1(4E)) are increased in patients with chronic idiopathic axonal neuropathy (CIAP) and diabetic distal symmetrical polyneuropathy (DSPN).3 |1.

UK 227786 is an inhibitor of phosphodiesterase 5 (PDE5), used for treatment of prostatic diseases.

C 021 dihydrochloride is a potent CCR4 antagonist. C-021 (4-Quinazolinamine, 2-[1,4'-bipiperidin]-1'-yl-N-cycloheptyl-6,7-dimethoxy-) dihydrochloride potently inhibits functional chemotaxis in humans and mice with IC50s of 140 nM and 39 nM, respectively. It effectively prevents human CCL22-derived [35S]GTPγS from binding to the receptor (IC50: 18 nM).

Terpineol possesses antifungal activity against Trichophyton mentagrophytes, it also exhibits strong antimicrobial activity against periodontopathic and cariogenic bacteria. α-Terpineol (Terpineol) shows anticonvulsant, and anti-inflammatory activities, it inhibits the gene expression of the IL-6 receptor.

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.

Betaine chloride (Betaine hydrochloride) is an acidic form of betaine, a vitamin-like substance observed in grains and other foods; gains the amplification of DNA by decreasing the formation of secondary structure in GC-rich regions.

Taurine (2-Aminoethanesulfonic acid) is an organic acid widely distributed in animal tissues and is one of the constituents of bile acids. Taurine is involved in a number of processes related to energy expenditure and muscle function, and can treat fatigue and muscles as well as improve immune function.

18β-Glycyrrhetinic acid (Enoxolone) is the major bioactive component of Glycyrrhizae Radix and possesses anti-ulcerative, anti-inflammatory and antiproliferative properties.

L-Tryptophan (Tryptophane), an essential amino acid, is necessary for normal growth in infants and for nitrogen balance in adults. It is a precursor of SEROTONIN (hence its use as an antidepressant and sleep aid) and of INDOLE ALKALOIDS in plants. It can be a precursor to NIACIN, although inefficiently in mammals.

Flavanone (2-Phenylchroman-4-one)s from citrus fruits have also been shown to exert beneficial effects on human vascular function. In particular, chronic interventions with orange juice, or the pure flavanone hesperidin, resulted in a decrease in blood pressure in overweight volunteers and acute improvements in microvascular reactivity.

D-Phenylalanine, a necessary aromatic amino acid, is a precursor of thyroxine, dopamine, melanin, and noradrenaline (norepinephrine).
