  • Patent number: 5646246
    Abstract: The cytostatic, cyclic peptides; phakellistatin 4, phakellistatin 5, phakellistatin 6, phakellistatin 7, phakellistatin 8 and phakellistatin 9 were isolated from the Western Pacific Ocean sponge Phakellia costata. Structural determination was accomplished by utilizing high-field, 2D-NMR experiments and confirmed by results of FAB-MS/MS studies. The absolute configurations were deduced by analyzing the acid hydrolysates using chiral gas chromatographic analytical techniques. The new cyclic peptides were found to have significant in vitro P388 ED.sub.50 values which range between 0.18 .mu.g/ml and 4.1 .mu.g/ml.

  • Patent number: 5618925
    Abstract: The present invention relates to shark cartilage extracts and to a method of producing the same, these extracts having anti-angiogenic properties (reduction of the area of blood vessels observed in vivo on experimentally induced tumors), tumor regressive activity in vivo as well as demonstrating a direct inhibitory effect on tumor cell lines. This process does not involve any denaturing solvent or product and does not involve the use of any enzymes. It consists of obtaining a blend of whole cartilage in an aqueous solution of neutral pH, preferably pure water, this blend being centrifuged and the pellet and supernatant kept for further processing. The pellet is lyophylized and tested for anti-tumor and anti-angiogenic activities in vivo and in vitro, with or without supernatant. The supernatant has been shown to have anti-angiogenic and tumor regressive activities in vivo. The composition of the supernatant has then been investigated by different ways.

  • Patent number: 5612522
    Abstract: A potassium aluminosilicate is used as a filtration media for filtering water to remove dissolved oxygen, hardness and other dissolved gases and impurities from the water, such as ammonia, hydrogen, hydrogen sulfide and sodium sulfite. The particular potassium aluminosilicate is a mesoporous amorphous material formed under ultraviolet light or sunlight to produce pore sizes of 60 .ANG. to 250 .ANG. at ambient temperatures ( C.) and in a low relative humidity (5%-20%). Sodium may be displaced in the zeolite media by potassium so that advantageous removal of impurities in the water occurs without introducing sodium into the water. The potassium aluminosilicate of the present invention may be used as a second stage filter to a first stage filter composed of strong base anion media charge with potassium carbonate or bicarbonate.
