Vanadium (IV) metallocene complexes having sperm motility inhibiting activity

Novel spermicidal compounds which are organometallic cyclopentadienyl metal complexes, particularly vanadium IV complexes, are described including corresponding contraceptive and therapeutic compositions and method for providing contraception and selective killing of testicular germ cells. Included among the vanadium complexes are vanadocene dichloride, vanadocene dibromide, bis (methyl cyclopentadienyl) vanadium dichloride, vanadocene diiodide, vanadocene di-pseudohalides, and others. Most active found was vanadocene diselenocyanate.

Azt derivatives exhibiting spermicidal and anti-viral activity

Contraceptive activity as well as anti-viral protection can be provided by contraceptive compositions containing a pyrimidine-based nucleoside or nucleotide exhibiting spermicidal or sperm-immobilizing activity. In one example, the active ingredient contains a thymine ring (e.g. AZT) that has 5-halo, 6-alkoxy substitution. Additional improvements in anti-HIV activity for certain AZT derivatives are seen by providing the pentose ring of AZT with aryl phosphate substitution.
