  • Patent number: 8552195
    Abstract: The method in accordance with the present invention has: mixing E2M, an organic solvent, a weak base, sodium dithionite, and a phase transfer catalyst to obtain an E2M mixture solution; heating the E2M mixture solution and adding water to obtain a heated E2M aqueous solution having an organic layer; and extracting the organic layer from the heated E2M aqueous solution, and condensing and drying the organic layer to obtain donepezil. Employing sodium dithionite as a reducing agent improves safety over hydrogen gas used in conventional methods and lowers the cost in contrast to the conventional noble metal catalysts that are extremely expensive. Furthermore, the method of the present invention requires only 60 minutes of reaction time to synthesize donepezil with a promising yield more than 85%, which greatly raises the efficiency and economic value of the manufacture of donepezil.

  • Patent number: 8252814
    Abstract: Agents for improving potency of the urinary bladder which comprise an amine compound of non-carbamate-type having an acetylcholinesterase-inhibiting action. Particularly, crystals of a tricyclic, condensed, heterocyclic derivative are provided, which possess an excellent action to inhibit acetylcholinesterase and an action to improve the excretory potency of the urinary bladder. As an example, crystals of 8-[3-[1-[(3-fluorophenyl)-methyl]-4-piperidinyl]-1-oxopropyl]-1,2,5,6-tetrahydro-4H-pyrrolo[3,2,1-ij]quinolin-4-one or a salt thereof and pharmaceutical compositions containing them are disclosed.

  • Publication number: 20120202756
    Abstract: The present invention relates to prodrugs of a wide variety of drugs and pharmaceutical compositions containing such prodrugs. Methods for minimizing locally mediated (from within the gut lumen) adverse gastrointestinal events associated with the underivatised drug and increasing the sustainment of plasma drug levels with the aforementioned prodrugs are also provided. Thus, the present invention relates to the use of prodrugs of a wide diversity of drugs (other than opioids) to transiently inactivate them and so reduce directly, locally mediated adverse gastrointestinal (GI) side-effects normally evident after administration of the parent compound. Additionally, such prodrugs may confer improved pharmacokinetics.
