diterpenoids

Lasiodonin is a natural product isolated from the leaves of Isodon parvifolius.

Lophanthoidin E is a kind of natural product derived from the herbs of Rabdosia lophanthoides.

Paclitaxel (Taxol) is a natural product and a microtubule polymer stabilizer. Paclitaxel has anti-tumor activity and causes cell death by inducing mitotic arrest, apoptosis, and cell autophagy.

Forskolin (Coleonol) is a natural product, an adenylate cyclase activator (EC50=0.5 μM). Forskolin increases cAMP levels, activates PXR and FXR, and induces autophagy. Forskolin produces positive inotropic effects in the heart, and has platelet anticoagulant and antihypertensive effects.

Punicalin exerts anti-inflammatory, antioxidative, and anti-hepatotoxic activities, it shows inhibitory activity on HIV-1 reverse transcriptase in a dose-dependent manner, with an IC50 of 0.11 microg/ml (0.14 microM).

Phorbol 12-myristate 13-acetate (PMA) is a natural phorbol ester that acts as an activator of PKC, SphK, and NF-κB, and is commonly used to induce differentiation of THP-1 cells and establish dermatitis models.

Thapsigargin is a natural product, an inhibitor of sarcoplasmic/endoplasmic reticulum Ca2+ ATPase (SERCA) and an endoplasmic reticulum stress inducer. Thapsigargin increases cytoplasmic calcium concentration by blocking the ability of cells to pump calcium into the sarcoplasmic and endoplasmic reticulum.

Geranylgeranyl pyrophosphate tetrabutylammonium(1:2) is one of the endogenous cholesterol and intermediates produced by the mevalerate pathway. Geranylgeranyl pyrophosphate tetrabutylammonium(1:2) is the common precursor of diterpenoids, for example, Paclitaxel. It can be used for cancer research.

Retinyl acetate (Vitamin A acetate) is a group of unsaturated nutritional hydrocarbons, that contains retinal, retinol, retinoic acid, and several provitamins A carotenoids, among which beta-carotene is the most important.

Docetaxel (RP-56976), a semi-synthetic analog of paclitaxel, is a microtubule depolymerization inhibitor (IC50=0.2 μM) that attenuates the effects of bcl-2 and bcl-xL gene expression and exhibits apoptosis-inducing, anti-tumor activity.

Isotretinoin (13-cis-Retinoic acid) binds to and activates nuclear retinoic acid receptors (RARs), which act as transcription factors that promote cell differentiation and apoptosis. This naturally occurring retinoic acid has potential antineoplastic activity, exhibits immunomodulatory and anti-inflammatory responses, and inhibits ornithine decarboxylase, thereby decreasing polyamine synthesis and keratinization.

10-Deacetylbaccatin-III is an intermediate for the preparation of taxol analogs, possessing anti-cancer activity.

Ginkgolide B (BN-52021) is a PAFR antagonist(IC50=3.6 μM) isolated from Ginkgo biloba.

Oridonin (NSC-250682) is a diterpenoid isolated from Rabdosia rubescens with anti-tumor, anti-bacterial and anti-inflammatory effects. It acts as an inhibitor of AKT, with IC50s of 8.4 and 8.9 μM for AKT1 and AKT2.

Andrographolide (Andrographis)(Andrographis), an irreversible antagonist of NF-κB, has anti-inflammatory and anti-platelet aggregation activities and potential antineoplastic.

Sclareolide (Norambreinolide) is a sesquiterpene lactone natural product derived from various plant sources including Salvia yosgadensis, Salvia sclarea, and cigar tobacco. It is a close analog of Sclareol, a plant antifungal compound.

A natural, noncaloric sweetener with a potency 300 times more than that of regular sucrose. Exhibits transepithelial p-aminohippurate transport via organic anion transport system interference.

Tanshinone IIA sulfonate sodium (Tanshinone IIA sodium sulfonate) is a water-soluble derivative of tanshinone IIA extracted from Savia miltiorrhiza; a potent negative allosteric modulator of the human purinergic receptor P2X7. Tanshinone IIA sulfonate sodium (12.5 μM) inhibits hypoxia-induced PKG and PPAR-γ downregulation in PASMCs and distal pulmonary arteries of rats.

Rebaudioside D is a potential sweetener. Rebaudioside D shows similar stability when exposed to simulate stomach and small intestine fluids, with susceptibility to hydrolytic degradation by enteric bacteria collected from the cecum.

Sclareol, a labdane-type diterpene isolated from clary sage (Salvia sclarea), exerts growth inhibition and cytotoxic activity against a variety of human Y cell lines.

Abietic Acid (Sylvic acid) is a diterpene extracted from Pimenta racemosavar. grissea with antimicrobial, antiproliferative and anti-obesity activities. It inhibits lipoxygenase activity and may be studied in allergic diseases.

Astaxanthin (trans-Astaxanthin) is a keto-carotenoid in the terpenes class of chemical compounds. It is classified as a xanthophyll but it is a carotenoid with no vitamin A activity. It is present in most red-colored aquatic organisms. Astaxanthin has shown to mediate anti-oxidant and anti-inflammatory actions. It may be found in fish feed or some animal food as a color additive.

Rebaudioside A (Reb A) is a novel agent of glycoside clathration of pharmacons, acts as α-glucosidase inhibitor.

PHYTOL (trans-Phytol) , a diterpene alcohol from chlorophyll widely used as a food additive and in medicinal fields, shows antinociceptive and antioxidant activities as well as anti-inflammatory and antiallergic effects. It is a specific activator of PPARα.
