Article Abstract:
New classes of antibiotics are urgently needed to fight infectious organisms that have become resistant to commonly used antibiotics. The genes for drug resistance can be passed from one organism to another, even if the organisms are not related. One strategy is to design drugs that are resistant to enzymatic degradation by the bacteria. Increasing vaccination against infectious diseases may eliminate the need for certain antibiotics. One promising approach is to identify bacterial genes that are only expressed during infection and block their expression. It could take another decade to develop and test new antibiotics, leaving the prospect of potentially deadly diseases that are essentially untreatable.

Article Abstract:
Researchers are investigating the potential therapeutic use of natriuretic peptides. These are small proteins produced by the heart and brain. Atrial natriuretic peptide (ANP), and brain natriuretic peptide (BNP) are the most well-known peptides. Both ANP and BNP increase sodium and water excretion and dilate blood vessels. For this reason, they may be effective antihypertensive agents and might also be used to treat congestive heart failure. Blood levels of ANP and BNP are increased in congestive heart failure and heart attack. Measuring these levels could identify patients with early-stage heart disease.

Article Abstract:
The therapeutic use and side effects of beta lactamase inhibitors are reviewed. Penicillin and related antibiotics belong to a class of drugs called beta lactams. However, many bacteria produce an enzyme called beta lactamase that can inactivate penicillin. Consequently, beta lactamase inhibitors are used to inhibit the bacterial enzyme so penicillin can kill the bacteria.
