phorbol

Phorbol (4β-Phorbol), a plant-derived diterpene, is a tumor promoter through the activation of protein kinase C.

Phorbol 12-myristate 13-acetate (PMA), a member of the phorbol ester group of natural products, activates PKC, SphK, and NF-κB, and induces THP1 cell differentiation.

Phorbol 13-acetate is a natural product for research related to life sciences. The catalog number is TN4768 and the CAS number is 32752-29-7.

4-Deoxy-4α-phorbol, a tetracyclic diterpene identified in E. desmondi, serves as a precursor in the semisynthesis of compounds inhibiting HIV-1-induced cytopathic effects in MT-4 cells and the creation of 4α-phorbol esters.

(Rac)-Phorbol-12-(2-methylbutyrate), a natural product, can be isolated from croton oil [1].

Phorbol 12-tiglate, a derivative of Phorbol, which in turn is a hydrolyzed product of Croton oil, plays a role in tumor promotion through activation of protein kinase C. This compound and its related derivatives are employed in the construction of carcinogenic models for biomedical research [1].

The compound is extracted from Croton tiglium dried fruit.

12-Deoxyphorbol 13-palmitate, a monomer derived from the roots of Euphorbia fischeriana, exhibits notable antitumor activity. This compound induces cell cycle arrest and apoptosis in gastric cancer cells by modulating key cell cycle regulators, such as cyclin B, cyclin A, and CDC2. Additionally, 12-Deoxyphorbol 13-palmitate significantly diminishes liver fibrosis by targeting APOL2 and impairing the APOL2–SERCA2–PERK–HES1 signaling pathway.

Platycodin D may stimulate TNF-α synthesis or inhibit degradation of TNF-α mRNA. Platycodin D (10 30 μM) suppresses prostaglandin E2 production in rat peritoneal macrophages stimulated by the protein kinase C activator 12-O-tetradecanoyl phorbol 13-acetate (TPA). Platycodin D and D3 are useful as expectorant agents in the treatment of various airway diseases, they can increase mucin release from rat and hamster tracheal surface epithelial cell culture and also from intact rat trachea upon nebulization.

Gliovirin is a fungal metabolite that has been found inT. harzianumand has fungicidal, antimicrobial and anti-inflammatory activities.1It is active against the plant pathogenic fungusP. ultimum(MIC = 60 ng/ml) and the parasiteT. brucei brucei(IC50= 90 ng/ml), but has no effect on the plant pathogenic fungiR. solani,P. omnivorum,T. basicola,R. arrhizus, andV. dahliaeor the bacteriaB. thuringiensis,P. fluorescens, andX. malvacearumwhen used at concentrations up to 1,000 ng/ml.2,3Gliovirin decreases phorbol 12-myristate 13-acetate (TPA)- and ionomycin-induced increased expression of COX-2 (IC50= 1 μM) and protein levels of IL-2 in Jurkat cells (IC50= 5.2 μM).1 1.Rether, J., Serwe, A., Anke, T., et al.Inhibition of inducible tumor necrosis factor-α expression by the fungal epipolythiodiketopiperazine gliovirinBiol.

Lyso-globotriaosylceramide is a form of globotriaosylceramide that is lacking the fatty acyl group. It binds to Shiga toxin 1 (Stx1) in the presence of cholesterol and phosphatidylcholine but does not bind Stx2. It also reduces viability and aggregation of human neutrophils induced by phorbol 12-myristate 13-acetate when used at concentrations of 50 and 1 μM, respectively. Lyso-globotriaosylceramide accumulates in the brain, heart, kidney, liver, lung, and spleen in a mouse model of Fabry disease, a lysosomal storage disorder characterized by a deficiency in the enzyme α-galactosidase A. It also accumulates in the urine, kidney, and plasma of patients with Fabry disease. Lyso-globotriaosylceramide levels decrease in response to administration of the α-galactosidase inhibitor 1-deoxygalactonojirimycin in a transgenic mouse model of Fabry disease. Decreases in plasma and urine concentrations of lyso-globotriaosylceramide have been used as a biomarker for efficacy of enzyme replacement therapy (ERT) and other therapies in the treatment of Fabry disease.

25S-Inokosterone exhibits potent inhibition against TNF-expression levels in A23187 plus phorbol-myrisrate acetate-induced RBL-2H3 cells. 25S-Inokosterone has excellent anti-atopy activity, thus 25S-Inokosterone could be used to a large range of functional anti-atopy cosmetics.

Shanziside (Shanzhiside) has immunosuppressive activity, it shows significant inhibition of IL-2 secretion by phorbol myristate acetate and anti-CD28 monoclonal antibody co-stimulated activation of human peripheral blood T cells.

Sphingosine (d14:1) is a bioactive sphingolipid that has been found in B. mori (silkworm), P. clarkii (crayfish), and A. aurita (jellyfish) extracts. It increases the germination rate of N. rileyi, an entomopathogenic fungus, with an EC50 value of 10.2 nM. Sphingosine (d14:1) inhibits protein kinase C (PKC) in vitro (IC50 = 7.3 mol%) as well as superoxide generation induced by phorbol 12-myristate 13-acetate in neutrophils and reduces growth of CHO cells (IC50s = 19 and 8 μM, respectively).

(+)-Oleuropeic acid shows potent in vitro antitumor-promoting activity, it also suppresses an in vivo two-stage carcinogenesis induced with nitric oxide and 12-O-tetradecanoyl phorbol 13-acetate (TPA) on mouse skin.

Beta-Tocopherol has effects on human erythroleukemia cell (HEL) adhesion induced by phorbol 12-myristate 13-acetate (PMA).

Sapintoxin A, a phorbol ester, is isolated from the immature fruits of Sapium indicum.

25R-Inokosterone exhibits potent inhibition against TNF-expression levels in A23187 plus phorbol-myrisrate acetate-induced RBL-2H3 cells. 25R-Inokosterone has excellent anti-atopy activity, thus 25R-Inokosterone could be used to a large range of functional anti-atopy cosmetics.
