Kaurenoic acid (kaurenoate) has anti-inflammatory potential in acetic acid-induced colitis, decreases in MDA level. Kaurenoic acid exerts a uterine relaxant effect acting principally through calcium blockade and in part, by the opening of ATP-sensitive potassium channels. Kaurenoic acid exhibits an analgesic effect in a consistent manner and that its mechanisms involve the inhibition of cytokine production and activation of the NO-cyclic GMP-protein kinase G-ATP-sensitive potassium channel signaling pathway. Kaurenoic acid derivatives have an antimicrobial activity of substituted on carbon-15 at concentrations greater than or equal to 250 μg ml. Kaurenoic acid has inhibitory effects on the LPS-induced inflammatory response in RAW264.7 macrophages.

Ferulamide (4-Hydroxy-3-methoxycinnamide), a Ferulic acid derivative, shows potent inhibitory activity against arachidonic acid-induced platelet aggregation.

3-O-Methylquercetin is a selective and competitive PDE3 PDE4 inhibitor, and inhibits PDE3 than PDE4 with a low K(m) value; it inhibits total cAMP- and cGMP-phosphodiesterase (PDE) of guinea pig trachealis at low concentrations.

1. Crotonoside (Isoguanosine) has much more active than adenosine in reducing the blood pressure in rabbits and cats, in decreasing the tone of isolated intestinal strips of the rabbit, guinea pig and hamster and in stimulating the isolated uterus of guinea pigs and hamsters. 2. Crotonoside inhibits the growth of S-18 and Ehrlich solid tumor in mice at the optimal doses of 96 mg kg day x 12 and 48 mg kg day x 12, with 1-T C values of 65% and 6%, respectively.
