| Description | Ayanin has vasorelaxant activity, it also may have the potential for use in treating allergic asthma. The IC50 value of Ayanin is 2.2microM for inhibiting interleukin IL-4 production from purified basophils. Ayanin is a non-selective phosphodiesterase1-4 inhibitor and can be used for respiratory disease researches. |
| In vitro | Incubation of human leukemia cells with Ayanin diacetate induced G(2)-M phase cell cycle arrest and apoptosis which was prevented by the non-specific caspase inhibitor z-VAD-fmk and reduced by the overexpression of Bcl-x(L). Ayanin diacetate-induced cell death was found to be associated with: (i) loss of inner mitochondrial membrane potential, (ii) the release of cytochrome c, (iii) the activation of multiple caspases, (iv) cleavage of poly(ADP-ribose) polymerase and (v) the up-regulation of death receptors for TRAIL, DR4 and DR5. Moreover, the combined treatment with Ayanin diacetate and TRAIL amplified cell death, compared to single treatments. |
