Cinnamtannin B-1 is a naturally occurring A-type proanthocyanidins, available in a limited number of plants, including C. zeylanicum and L. nobilis, that exhibit a large number of cellular actions mostly derived from its antioxidant activity, including antitumoral activity mediated by a selective pro-apoptotic action in a number of tumoral cell lines associated with a remarkable antiapoptotic activity in normal cells. In addition, cinnamtannin B-1 shows antithrombotic actions through inhibition of platelets' endogenous ROS generation, Ca2 mobilization and subsequently aggregation. This has been reported to be especially relevant in platelets from diabetic patients where cinnamtannin B-1 reverses both platelet hypersensitivity and hyperactivity. Considering the large number of cellular effects of cinnamtannin B-1, this compound might be further investigated for the development of therapeutic strategies based on its use for thrombotic disorders or certain types of cancer. Cinnamtannin B-1 is a potent antioxidant and protective agent against oxidative stress and apoptosis in human platelets. Cinnamtannin B-1 is a Cox-2 (cyclooxygenase-2) inhibitor. Cinnamtannin B1 was a potent cancer cell proliferation inhibitor and a good intracellular antioxidant.

(S)-ketorolac is the enantiomer of ketorolac, a nonsteroidal anti-inflammatory drug. (S)-ketorolac exhibited potent cyclooxygenase (COX1 and COX2) enzyme inhibition. (S)-ketorolac is considered to be active enantiomer of racemic ketorolac.

Aporeine (Roemerine) is an aporphine alkaloid that can be isolated from many plants such as Annona senegalensis, Turkish Papaver and Rollinialeptopetala. Aporeine has been reported to exhibit antibacterial activity. It has also been demonstrated to have certain antifungal activity. Aporeine showed selective inhibitory effect on Cox-2.

Isoorientin is a common C-glycosyl flavone in the human diet. It has been isolated from several plant species, including Phyllostachys pubescens, Crataegus monogyna and Crataegus pentagyna, Patrinia villosa Juss, Drosophyllum lusitanicum, buckwheat, Arum palaestinum, and Rumex and Swertia. Isoorientin possesses significant anti-nociceptive and anti-inflammatory activities. Significantly protected PC12 nerve cells from 6-OHDA-induced apoptotic neurotoxicity and reduced the proliferation of HepG2 cells. Isoorientin showed anti-RSV (respiratory syncytial virus) activity.

Cucurbitacin E (CuE), a potent member of triterpenoid family isolated from plants, has been confirmed as an antitumor agent by inhibiting proliferation, migration, and metastasis in diverse cancer. Cucurbitacin E nhibits OS tumor growth and invasion through inhibiting the PI3K/Akt/mTOR signaling pathway. CuE can be considered to be a promising anticancer agent for OS. Cucurbitacin E exerts anti-inflammatory actions. It inhibited both COX enzymes with more selectivity toward COX-2. CuE has been reported to possess anti-inflammatory and anti-tumorigenic properties mediated by its action on the cellular cytoskeleton, on mitotic pathways as well as on cellular autophagy.

Echinocystic acid (EA) is a pentacyclic triterpene isolated from the fruits of Gleditsia sinensis Lam, has potent antioxidant, anti-inflammatory and anti-tumor properties. Echinocystic acid (EA) inhibit the formation of osteoclast. EA inhibit RANKL-induced NF-κB activation and ERK phosphorylation in BMMs. Echinocystic acid inhibits IL-1β-induced COX-2 and iNOS expression in human osteoarthritis chondrocytes. Echinocystic acid also inhibited TPA-induced myeloperoxidase activity, as well as COX-2, iNOS, TNF-α and IL-1β expressions. Echinocystic acid inhibited NF-κB in TPA-treated mouse ears, as well as in lipopolysaccharide-stimulated peritoneal macrophages. Its potency is comparable with that of dexamethasone. These findings indicate that echinocystic acid may ameliorate inflammatory diseases, such as dermatitis. EA inhibited ACAT and DGAT, with IC50 values of 103 and 139  uM, respectively, and exhibited no significant effect on HMG-CoA reductase activity. The present findings suggest that EA may exert hypolipidemic effect by inhibiting the activity of ACAT and DGAT.
