Abstract:
Use of phthalide dipolymers for broad spectrum antitumor. The compounds according to this invention can directly inhibit proliferation of tumor cells, induct apoptosis of tumor cells, and indirectly inhibit the growth of tumor through inhibiting angiogenesis. One of said compounds or more can be used as anti-tumor agents, or in combination with chemotherapeutic agents for enhancing curative effect and reducing toxicity and side effect.
Abstract:
Compositions of matter comprising 5-phenoxyalkoxypsoralen compounds and their method of synthesis and use. The compounds are useable to treat diseases or disorders in human or animal subjects, including autoimmune diseases. The compounds inhibit potassium channels, including the Kv1.3 channel and at least some of the therapeutic effects of such compounds may be due at least in part to potassium channel inhibition. In some embodiments, the compounds are more selective for certain potassium channels (e.g., Kv1.3 channels) than other potassium channels (e.g., Kv1.5 channels).
Abstract:
This invention provides cancer-active tricyclic and tetracyclic oxypyrones and a method of synthesizing these compounds. Preferred compounds have aryl groups at the 3-position of the oxypyrone ring. The tricyclic oxypyrone synthetic method is a simple condensation reaction of pyrones with cyclohexenecarboxaldehydes, providing high yields and using few steps. The tetracyclic oxypyrone synthetic method is a simple condensation reaction of carvones with pyrones.
Abstract:
The present invention relates to a method for producing and purifying an anhydrous sugar alcohol in high yield and to a high degree of purity by means of a simple process and device, the invention comprising: a step in which a sugar alcohol and an acid catalyst are reacted in a reactor while at the same time evaporating the product therefrom; a step in which the evaporated product is cooled so as to remove water and obtain a crude anhydrous sugar alcohol; and a step in which the crude anhydrous sugar alcohol is introduced into a melt-crystallization process, thereby obtaining a high purity anhydrous sugar alcohol.
