Summarize the five modes of action of antimicrobial drugs, withspecific examples of their effects.

Diff erentiate between antibiotics, synthetic drugs, and semisynthetic drugs.

Broad-spectrum drugs target a wide variety of bacterial pathogens. Even when the broad-spectrum drug is capable of killing a target pathogen, it may not be the best treatment. Which statement best explains why a broad spectrum drug might be an undesirable treatment choice?   Broad-spectrum antimicrobials are usually toxic to the host cells. Broad-spectrum antimicrobials only work if they are used shortly after the infection begins. Broad-spectrum antimicrobials may kill much of the normal microbiota. Broad-spectrum antimicrobials are not able to kill bacteria that are in their log phase of growth. Broad-spectrum antimicrobials may stimulate excess growth of the normal microbiota.

Draw the bacteria cell and indicate all the drug target in the bacteria cell and which drugs are able to attack each part.

Explain the advantages and disadvantages of developing newdrugs based on existing drug analogs. What other methodsexist for developing new drugs?

Briefly Explain the challenges of developing anticancer drugs? Discuss with example. discuss at your own words

(iii) In terms of their modes of action at a molecular level, antibiotics and antibacterial agents can be collected into several categories. Give the classifications involved and for each category, an example of a relevant compound or type of compound.
