  • Water-soluble solid pharmaceutical inclusion complexes and their aqueous solutions for oral, ophthalmic, topical or parenteral use containing a macrolide and certain cyclodextrins
    Patent number: 9169269
    Abstract: This invention relates to new water-soluble solid pharmaceutical inclusion complexes and their aqueous solutions for oral, ophthalmic, topical or parenteral use containing a macrolide and certain cyclodextrins. More particularly the invention relates to new water-soluble solid pharmaceutical inclusion complexes and their solutions in aqueous solvents, said compositions containing a) as an active ingredient a macrolide such as Rapamycin, Pimecrolimus, Temsirolimus, Everolimus or Tacrolimus in an amorphous form and optionally in the form of their polymorphic hydrates or solvates e.g. solvates formed with acetone or ethanol. b) a large surface cyclodextrin, such as gamma cyclodextrin—whereby the weight ratio of said macrolide to said cyclodextrin ranges between 1:111 and 1:333.
    Type: Grant

  • Chemo-enzymatic approach to the synthesis of pimecrolimus
    Patent number: 8778636
    Abstract: Processes for preparing pimecrolimus starting from ascomycin, exploiting the selectivity characteristics of the purified enzymatic systems particularly regarding the selective functionalization of the hydroxyl groups present in position 24 and 33 of ascomycin. Such method represents the first example of chemoenzymatic synthesis for preparing pimecrolimus.
