    Design, Synthesis, and Pharmacological Evaluation of Monocyclic Pyrimidinones as Novel Inhibitors of PDE5
    摘要:
    Cyclic nucleotide phosphodiesterase type 5 (PDES) is a prime drug target for treating the diseases associated with a lower level of the cyclic guanosine monophosphate (cGMP), which is a specific substrate for PDE5 hydrolysis. Here we report a series of novel PDE5 inhibitors with the new scaffold of the monocyclic pyrimidin-4(3H)-one ring developed using the structure-based discovery strategy. In total, 37 derivatives of the pyrimidin-4(3H)-ones, were designed, synthesized, and evaluated for their inhibitory activities to PDES, resulting in 25 compounds with IC50 ranging from 1 to 100 nM and 11 compounds with IC50 ranging from 1 to 10 nM. Compound 5, 5,6-diethyl-2[2-n-propoxy-5-(4-methyl-1-piperazinylsulfonyl)phenyl]pyrimid-4(3H)-one, the most potent compound, has an excellent IC50 (1.6 nM) in vitro and a good efficacy in a rat model of erection. It thus provides a potential candidate for the further development into a new drug targeting PDE5.

    摘要:

    The subject of this invention provides a method of preparation and isolation of water-insoluble or partially soluble salts of vardenafil of formula 1, in particular its salts with acids in the ratio of components 1 : 1 (of formula 2a, HA stands for any acid), and of crystalline hydrates of said salts. These solid forms, in particular crystalline vardenafil hydrochloride trihydrate of formula 4, can be directly, without additional purification, used in preparation of a medicine for the therapy of erectile dysfunction. The present solution is based on using water as a suitable medium both for obtaining of extracts of the water-soluble forms of vardenafil, and for isolation and subsequent crystallization of solid water-insoluble or partially soluble salts of vardenafil with acids (1 : 1). Crystallization of the isolated salts takes place after adjustment of pH of the aqueous solutions by means of aqueous solutions of bases or acids, wherein no organic solvent or a mixture thereof with water is needed for the crystallization. The method according to this invention reduces costs for organic solvents, increases efficiency of isolation of the vardenafil salts with acids, and facilitates preparation of poorly stable hydrates of these salts.
