  • Patent number: 9115160
    Abstract: This invention discloses a solvent-free process for the preparation of cyclophosphamide. According to this invention, there is no solvent used during the reaction step for preparing cyclophosphamide, so that the total volume of the reaction for preparing cyclophosphamide can be reduced and the manufacture of cyclophosphamide can become more efficient. Furthermore, the above solvent-free process for the preparation of cyclophosphamide is more simply operated, more economic, and more environmental friendly than the preparation of cyclophosphamide in the prior art.

  • Patent number: 8946295
    Abstract: A method for promoting wound healing and preventing scar formation in a variety of wounds in skin, mucosa, and cornea. The method comprises administering a therapeutically effective amount of a histone deacetylase inhibitor or a hyperacetylating agent. The histone deacetylase inhibitor or hyperacetylating agent is capable of stimulating multiple cytokines/growth factors in the early phase of wound healing, and suppressing fibrogenic cytokines/growth factors in the late phase of tissue remodeling in the wound site, and is useful in promoting epithelial cell re-growth and reducing excessive collagen accumulation, which results in rapid wound closure with reduced scaring.
