Nitric oxide serves important roles in mammalian bioregulation and immunology. This has prompted research into metal nitrosyl complexes, which display low thermal reactivity but which are photochemically active to release NO and potentially deliver it to biological targets. One such complex that has been studied with ns-TRIR in the z/(NO) region and also conventional flash photolysis is Roussin s black salt anion, [Fe4S3(NO)7] . The TRIR experiments identified an intermediate species with a z/(NO) that was shifted to lower frequency, relative to the parent complex. This was identified as the product of NO photodissociation from one of the Fe(NO)2 units. [Pg.95]

Finally, it is important to know whether laboratory demonstrated effects can be repeated in field trials. Table VI shows that field experiments with SSHB confirm many of the results we have obtained in greenhouse studies. Consequently brassinosteroids may become of interest as bioregulators that reduce drought stress in sugar-beet plants. [Pg.218]

Biofunctional natural products with low molecular weights are classified as shown in Table 1.1. Chemical studies on vitamins, hormones and antibiotics started in the first half of the 20th century, while those on semiochemicals began in the middle of the 20th century. This book treats the chemical synthesis of hormones, pheromones and other bioregulators such as allelochemicals. [Pg.1]

Smith et al. (611) studied the effect of vanadyl sulfate on catharanthine and ajmalicine production in various cell lines of C. roseus. After 5 days of culture 50 mg/liter vanadyl sulfate was added. The amounts of catharanthine and ajmalicine were determined after 3 days of incubation with the bioregulator. Alkeiloid production was stimulated in most cases, but the exact effect depended greatly on the cell line used. [Pg.123]
