generally treated by Metronidazole and Fluconazole respectively. Poor vaginal efficacy, drug-resistance and non-spermicidal nature limit their use as topical microbicidal contraceptives. Bis(dialkylaminethiocarbonyl)disulfides (4–38) were designed as dually active, non-surfactant molecules capable of eliminating Trichomonas vaginalis and Candida strains as well as irreversibly immobilizing 100% human sperm
A crosslinkable acrylic rubber composition exhibiting superior balance between the storage stability and cure rate, and having only minimal risk of corroding metals or being contaminated by metals. The cured products made from the composition have excellent tensile strength, permanent compression set, and water resistance. The composition which comprises (1) a halogen-containing acrylic rubber, (2) a triazine thiol compound, (3) a dithiocarbamine acid derivative or a thiuram sulfide compound, or both, (4) a hydrotalcite compound or an organotin compound, or both, (5) an aromatic carboxylic acid compound or an acid anhydride thereof, or both, (6) a white filler with a pH of 2-10, and (7) a silane coupling agent.

An acrylic rubber that is a copolymer in which 1 to 4 wt.% of a reactive halogen group-containing vinyl monomer is copolymerized as a crosslinkable comonomer, wherein 45 to 65 wt.% of n-butyl acrylate, 10 to 35 wt.% of 2-methoxyethyl acrylate and 8 to 30 wt.% of ethoxyethoxyethyl acrylate are copolymerized in 100 wt.% of comonomers other than the crosslinkable comonomer. This ethoxyethoxyethyl acrylate-copolymerized acrylic rubber can suppress the reduction of oil resistance while improving cold resistance represented by a TR-10 value, and by compounding it with a vulcanizing agent corresponding to the crosslinkable group thereof, a crosslinkable composition is formed.
