Catalysis of dehydrogenation of 4-trans-(N,N-dimethylamino)cinnamaldehyde by aldehyde dehydrogenase.

4-trans-(N,N-dimethylamino)cinnamaldehyde (DACA) is a chromophoric and fluorogenic substrate of aldehyde dehydrogenase. Fluorescence of DACA is enhanced by binding to aldehyde dehydrogenase in the absence of catalysis both in the presence and absence of the coenzyme analogue 5'AMP. DACA binds to aldehyde dehydrogenase with a dissociation constant of 1-3 microM and stoichiometry of 2 mol mol(-1) enzyme.

Binding and incorporation of 4-trans-(N,N-dimethylamino) cinnamaldehyde by aldehyde dehydrogenase.

4-trans-(N,N-Dimethylamino)cinnamaldehyde (DACA) is a chromophoric substrate of aldehyde dehydrogenase (EC 1.2.1.

Mechanism of inhibition of aldehyde dehydrogenase by citral, a retinoid antagonist.

Low concentrations of citral (3,7-dimethyl-2,6-octadienal), an inhibitor of retinoic acid biosynthesis, inhibited E1, E2 and E3 isozymes of human aldehyde dehydrogenase (EC1.2.1.

Developing guidelines for smoking cessation interventions for pregnant adolescents.

More than 400,000 deaths a year in the United States are attributed to active and passive tobacco smoke exposure. Healthy People 2000 objectives target a reduction in the tobacco use of high-risk populations such as youth and pregnant women. This article describes guidelines for health professionals to address smoking cessation when working with pregnant adolescents and teen mothers who smoke.
