Abstract:
Combretum caffrum, a tree in the family Combretaceae, has been found to contain three 9,10-dihydrophenanthrenes (6,7-dihydroxy-2,3,4-trimethoxy; 7-hydroxy-2,3,4,6-tetramethoxy; and 2,7-dihydroxy-3,4,6-trimethoxy) that inhibit (ED50 2.2, 2.8, and 2.6 μg/mL) growth of the murine lymphocytic leukemia cell line. One phenanthrene (7-hydroxy-2,3,4,6-tetramethoxy) was also isolated with similar (ED50 2.0 μg/mL) activity. Structures for each of these substances, including a dihydrophenanthrene (2-hydroxy-3,4,6,7-tetramethoxy-9,10-dihydrophenanthrene), were determined by detailed high resolution nuclea

Abstract:
Photolysis of the phenanthrene/tetranitromethane charge-transfer complex yields the triad of phenanthrene radical cation, nitrogen dioxide, and trinitromethanide ion. Recombination of this triad in dichloromethane at 20° gives 9-nitrophenanthrene (1), trans-10-trinitromethyl-9,10-dihydrophenanthren-9-yl nitrate (2a), trans-9-nitro-10-trinitromethyl-9,10-dihydrophenanthrene (2b), and trans-10-trinitromethyl-9,10-dihydrophenanthren-9-ol (2c). Adduct formation is partially suppressed when trifluoroacetic acid (0.7 M) is added to the dichloromethane solvent at 20°, the major product identified bei

Abstract:
The chemical investigation of the roots and stems of Combretum laxum yielded a new dihydrostilbene derivative, 4′-hydroxy-3,3′,4-trimethoxy-5-(3,4,5-trimethoxyphenoxy)-bibenzyl (1), two phenanthrenes (2–3), and three dihydrophenanthrenes (4–6), along with one lignan, three triterpenoids, one aurone, one flavone, one naphthoquinone, and two benzoic acid derivatives. Their structures were determined by 1D and 2D nuclear magnetic resonance (NMR) spectroscopic techniques and/or mass spectrometry data.

In Taiwan, Ephemerantha lonchophylla is also used as a source of “Shi-Hu”. Recently, 2,5,6,7-tetramethoxy-9,10-dihydrophenanthren-1-ol and 2,3,4,7-tetramethoxy-9,10-dihydrophenanthrene were isolated from Ephemerantha lonchophylla and showed strong antitumor activity.

Abstract:
Time resolved spectroscopic studies of the photoisomerization reactions of cis-stilbene in solution have provided a great deal of information on these simple reactions (1-3). Transient absorption (1,2) and fluorescence (3) experiments have demonstrated that the initially created electronically excited cis-stilbene population (cis*) persists for 0.5 to 1.5 ps in room temperature solution-phase environments. Polarized transient absorption experiments and time-resolved fluorescence experiments indicate that during this time the cis* molecules retain most of the energy of the incident photon and a
