  • Patent number: 10058618
    Abstract: The present invention relates to a PAK1 blocking compound having a much higher bioavailability and cell permeability than traditional herbal PAK1 blockers or synthetic PAK1 blockers, and the uses thereof for treating cancer or other PAK1 dependent diseases or disorders. This PAK1 blocking compound comprises an ester of an acidic PAK1 blocker, or a pharmaceutically acceptable salt thereof. This PAK1-blocking ester may be prepared by esterifying a PAK1 blocker starting material with an alcohol; and treating the esterified PAK1 blocker with an aromatic azide to generate a 1,2,3-triazolyl derivative.

  • Patent number: 9040743
    Abstract: Provided is a method for producing n-propyl acetate, which is capable of obtaining high-purity allyl acetate with a low amount of coexisting water and is capable of producing n-propyl acetate with a high yield. The method includes an extraction process of subjecting a raw material liquid containing allyl acetate and water to an extraction operation using water as an extraction solvent and separating the extract into an oily phase and an aqueous phase, a distillation process of distilling the oily phase to obtain a distillate containing allyl acetate as a main component, and a hydrogenation process of subjecting the distillate to a hydrogenation reaction.

  • Patent number: 5580955
    Abstract: This invention provides for a mechanism to reverse the activated Ras induced malignant transformation of mammalian cells by use of certain peptides. Specifically, the anti-oncogenic protein fragments of the Neurofibromatosis type 1 protein (NF1) were found to reverse, inhibit, or otherwise interfere with the malignant transformation of V-HaRas induced transformed cells. The invention further identifies several specific fragments of the NF1 protein which are capable of reversing activated Ras induced transformation, including the NF338, NF91, NF78 and NF56 protein fragments. The invention also provides for nucleic acid molecules, cell lines, and expression vectors associated with the NF1 fragments, in addition to protein complexes of the NF1 and Ras proteins. A method for screening molecules which are capable of reversing activated Ras induced transformation is also disclosed herein.
