- The ribosome is the target for many important antibiotics. These drugs must discriminate between bacterial and eukaryotic ribosomes to achieve drug specificity and toxicity. For the two common antibiotics below, what is their mechanism of action and why are they more toxic to bacteria than eukaryotes? a) Tetracycline b) ErythromycinDiscuss the concept of microwave fixation and cryofixation, and why it is suitable for histochemistry and immunohistochemistry?Antibiotics that target bacterial molecules not previously exploited are desperately needed. One such target is the protein FtsZ. The small molecule 3-methoxybenzamide (3-MBA) is known to inhibit FtsZ in Bacillus subtilis but is not bacteriocidal. Nonetheless, researchers reasoned that 3-MBA offered a good starting point for the synthesis of a molecule that might be a potential drug candidate. Over 500 3-MBA analogues were synthesized and screened; one called PA190723 was extremely potent in its capacity to bind FtsZ and inhibit bacterial growth. In fact, when used in a mouse model, PA190723 was bacteriocidal against methicillinand multidrug-resistant Staphylococcus aureus. What makes FtsZ a good drug target? What preliminary information about 3-MBA would be helpful if you were designing the 3-MBA analogues? As these researchers move forward with clinical (human) testing, what other parameters and outcomes must be assessed besides the bacteriocidal activity of PA190723?
- The human intestinal tract is home to a vast, diverse microbial community. The bacteria that comprise this microbial community serve a number of important, beneficial functions. However, some bacterial species have been suggested to play a role in certain forms of cancer. One such bacteria is Fusobacterium nucleatum (i.e., F. nucleatum). Investigators wishing to study the role of F. nucleatum in colorectal cancer developed a new assay for detecting these bacteria in tumor tissue. In controlled experiments, the test was highly sensitive in detecting F. nucleatum and also had high specificity. To examine consistency in their test findings, the investigators also conducted repeat tests in 50 tissue samples. From these repeat tests, the investigators observed that the overall number of samples in which F. nucleatum was detected was almost identical (10 out of 50 on the first test vs. 11 out of 50 on the repeat test); for 9 samples, F. nucleatum was detected on both the initial and the…Identify the following by describing their functions: EF-G, EF-Tu, EF-Ts, EF-P, and peptidyl transferaseb.
