摘要:
Conophylline, contained in leaves of Ervatamia microphylla or Tabernaemontana divaricata, can induce non-tumor cells to differentiate into insulin-producing cells and thereby to produce insulin and also to lower blood glucose levels. Thus, in the present invention, dried products and extracts of leaves of Ervatamia microphylla or Tabernaemontana divaricata, which contain conophylline, are used as health foods for preventing and improving diabetes and obesity or health foods for lowering blood glucose levels.

摘要:
A compound isolated from Ervatamia microphylla has been found to be effective in inducing a change in cell morphology and growth habits of cultured transformant cell lines, and in reducing the tumor size in a living mammal. The compound is capable of inhibiting the function of oncogenes such as ras and src by inhibiting the function of the oncogene products. The compound is found to be represented by formula (I): ##STR1## Use of the compound as an oncogene function inhibitor, in a treatment of cancer, and in inducing changes in cell morphology and growth habits in transformant cell line are contemplated.
摘要:
A novel catalytic composition is described, useful for treating olefins or alcohols with carbon monoxide in the preparation of carboxylic acids comprising a solution containing copper carbonyl and a hydrated boron fluoride which optionally may contain a mineral acid such as sulfuric acid, phosphoric acid or hydrogen fluoride. The copper carbonyl functions as a co-catalyst for the hydrated boron trifluoride to enhance selectivity. The catalysts are especially suited for the preparation of neo acids.
摘要:
A process is disclosed for preparing vicinal dialkoxyalkanes by reacting a vicinal dihaloalkane with an alkanol in the presence of a hydrogen halide absorbing agent which is substantially insoluble in the alkanol.
