Unsaturated cuticular hydrocarbons serve as pheromones in insects. In D. melanogaster, these hydrocarbons are sexually dimorphic in both their occurrence and their effects. 7(Z),11(Z)-Nonacosadiene is a cuticular pheromone in female fruit flies that stimulates male courtship behavior. The biosynthesis of this C29 diene appears to be mediated by an elongase with female-based expression.
When compared to other caspase inhibitors, Z-DRHD-FMK inhibited caspase 6 activity more effectively than the general caspase inhibitor of Z-Val-Ala-Asp (OMe)-fluoromethy ketone (Z-VAD-FMK) or the caspase 6 inhibitor Z-Val-Glu(Ome)-Ile-Asp(OMe)-fluorometh
