Interaction of 3,4-diacylfuroxans with hydroxylamine hydrochloride results in the formation of substituted 4,5-bis (hydroximino)-4,5-dihydroisoxazoles, whereas the reaction of 3,4-bis(4-methylfurazanoyl-3)furoxan with hydrazine hydrate in acetic acid affords 3-[4,5-bis(hydroximino)-4,5-dihydro-]H-pyrazol-3-yl]-4-methylfurazan. N-Acyl-, N-nitro-, N-alkyl- and N-adamantyl derivatives of the latter compound have been synthesized. X-Ray structure determinations together with density functional theoretical calculations are reported. (C) 2003 Elsevier Science Ltd. All rights reserved.

The invention provides novel compositions and compounds that inhibit CatSper channel activity, that preferentially inhibits sperm hyperactivity over sperm motility, or both. The compounds of the invention are useful as contraceptive agents that may be adminstered to males, females, or concurrently to both sexual partners. The invention further provides methods of conducting drug discovery business and of conducting a reproductive medicine business. The invention also provides methods of identifying compounds that modulate sperm hypermotility.
