Methods of inducing ovulation
View Patent ↗The present invention relates to methods of inducing ovulation in a female host comprising the administration of a non-polypeptide cyclic adenosine monophosphate (cAMP) level modulator to the female host. In another aspect, the invention provides for specific administration of the phosphodiesterase inhibitor prior to the luteal phase of the host's ovulatory cycle. Preferred non-polypeptide cAMP level modulators include phosphodiesterase inhibitors, particularly inhibitors of phosphodiesterase 4 isoforms.
1. A method of combined treatment for stimulating follicular development and ovulation induction in a female host comprising:
(a) administering an agent which increases follicle stimulating hormone concentrations or has follicle stimulating hormone function and activity in the host during the follicular phase of the host's ovulatory cycle; and (b) administering an inhibitor of a phosphodiesterase 4 isoform to the host prior to the luteal phase of the host's ovulatory cycle, wherein the inhibitor of a phosphodiesterase 4 isoform is selected from the group consisting of: cis-4-cyano-4-(3-(cyclopentyloxy)-4-methoxyphenyl) cyclohexane-1-carboxylic acid; 3-(cyclopentyloxy)-N-(3,5-dichloropyridin-4-yl)-4-methoxybenzamide; 2-(4-(6,7-diethoxy-2,3bis(hydroxymethyl)napthalen-1-yl)pyridin-2-yl)-4-(3-pyridyl)pthalazin-1 (2H)-one hydrochloride; and 7-benzylamino-6-chloro-2-piperazino-4-pyrrolidinopteridine; roflumilast and arofylline.
2. The method of claim 1 , wherein the inhibitor of a phosphodiesterase 4 isoform is roflumilast.
3. The method of claim 1 , wherein the inhibitor of a phosphodiesterase 4 isoform is piclamilast.
4. The method of claim 1 , wherein the inhibitor of a phosphodiesterase 4 isoform is arofylline.
