Abstract: The synthesis and biological activity of indoloazepines and acid amine salts thereof which are structurally related to naturally-occurring hymenialdisine is disclosed. Naturally-occurring hymenialdisine obtained from the sponge is a potent inhibitor of production of cytokines interleukin-2 (IL-2) and tumor necrosis factor-? (TNF-?). The chemically-synthesized indoloazepines of the invention also inhibit production of IL-2 and TNF-?. The indoloazepines are useful for treating inflammatory diseases, particularly diseases associated with kinases NF-?B or GSK-3? activation or NF-?B activated gene expression products. The indoloazepines are useful for the treatment of cancer by the inhibition of kinases CHK1 and CHK2.

Abstract: The present invention provides modified cyclic nucleotide gated (CNG) channels. In particularly preferred embodiments, the modified CNG channels exhibit increased sensitivity and specificity for cAMP, as compared to wild-type CNG channels. In additional embodiments, regulation by Ca2+-calmodulin has been removed in the modified CNG channels. Convenient optical methods for detecting changes in cAMP, taking advantage of the Ca2+ permeability of the channel are also provided by the present invention. In addition, electrophysiological methods are further provided.

Abstract: Compositions and methods of using conjugated linoleic acid preparations enriched for the t10,c12 and c9,t11 isomers are disclosed. It is found that preparations of conjugated linoleic acid containing a ratio of t10,c12 to c9,t11 of about greater than 1.2:1 are desirable for a wide variety of nutritional, therapeutic and pharmacologic uses.
