MRSA Ab
Nanopharma is conducting
toxicology and pharmacologic studies of a new
antibiotic for the
treatment of methicillin-resistant
Staphylococcus aureus (MRSA).
Overview of
the disease
Methicillin-resistant Staphylococcus Aureus (MRSA) is a
specific strain of the
Staphylococcus aureus
bacterium that has
developed antibiotic
resistance to all
penicillins, including
methicillin and other
narrow-spectrum β-lactamase-resistant antibiotics. Although
staphylococcus infections such as MRSA
occur most frequently within hospitals and healthcare facilities
such as nursing homes and dialysis centers, these infections are
now epidemic and increasingly difficult to combat.
Conventional antibiotics and "superbugs"
Bacteria, like all living organisms, are
continuously adapting to environmental challenges. As a result of these
changes, conventional
antibiotics are increasingly unable to keep pace with drug-resistant bacterial
infections. Today, public
institutions such as hospitals, nursing homes and infant day care centers have
become breeding grounds for the most tenacious drug-resistant pathogens ("superbugs").
The result has been an alarming rise in drug resistant bacteria such as
staphylococci, enterococci, streptococci, and pneumococci infections, as well as
an increase in tuberculosis, and sepsis. For several decades, β-lactam
antibiotics have been widely used to control bacterial infections. Since the
discovery of penicillin, countless numbers of variations have been tested and a
variety of successful modifications have been made to the basic four-membered
ring structure which characterizes the generic β-lactam compound.
Despite the
advances in drug research, infections caused by bacteria such as methicillin-resistant
Staphylococcus aureus (MRSA) are becoming extremely difficult to treat
with conventional antibiotics, leading to a sharp rise in clinical complications
and enormous socio-economical costs.
There simply are not enough
new drugs in the pharmaceutical pipeline to keep pace with drug-resistant
bacterial infections.
The development of narrow spectrum antibacterial drugs which target new pathways
and biological entities (whether bacteriostatic or bacteriocidal) is in grave
demand.
Our technology
The search for
alternative antibiotics against staphylococcus infections requires the right
amount of good science, business acumen and commitment. Nanopharma's
technologies and compounds for the treatment of MRSA are not only effective but
also unique in their mechanism of action. Unlike other
β-lactam
antibiotics such as penicillin, which inhibit cell wall crosslinking proteins
and afford a broad spectrum of bacteriocidal activity, our N-thiolated lactams
are bacteriostatic in their behavior, highly specific and operate through an
entirely different mechanistic mode.
Furthermore, whereas most drugs require demanding multi-step
syntheses or semi-synthetic procedures, these compounds
can be prepared in a single chemical step, thereby simplifying production
systems and reducing costs. Accordingly,
our MRSA antibiotic is a efficient and effective way to turn
a basic chemistry discovery into a therapeutic product.
