Description:
Numerous spermicidal products are already marketed, including stand-alone
contraceptive foams, gels, films or creams, along with combined products
including condoms coated with spermicidal lubricants, sponges, etc.
Most such products contain nonoxynol-9 (N-9) or similar compounds in
substantial concentrations (3.5% in gels or creams). While widely used, these
products have limited efficacy, and may be deleterious to normal tissues - some
reports show increased rates of microbial infection, and lack of protection
against HIV transmission.
This invention consists of new chemical compounds or combinations of
compounds that kill human sperm cells and/or inhibit microbial infectivity and
are safer than traditional agents for use in contact with human tissues and/or
other mammalian cells.
ADVANTAGES
Fluorous surfactants have lower CMC values than comparable non-fluorous
homologs, and permit renaturation of proteins following exposure. These
compounds may act alone or in synergy with each other, with N-9, or with
non-fluorous compounds to enable gentler treatment conditions that lessen damage
to surrounding tissues while disabling sperm and/or microorganisms.
