A scientist discovers that a soil bacterium he has been studying produces an antimicrobial that kills gram-negative bacteria. She isolates and purifies the antimicrobial compound, then chemically converts a chemical side chain to a hydroxyl group. When she tests the antimicrobial properties of this new version, she finds that this antimicrobial drug can now also kill gram-positive bacteria. The new antimicrobial drug with broad-spectrum activity is considered to be which of the following?

resistant

semisynthetic

synthetic

natural

Simone Scott · Answer 1

semisynthetic

Explanation:

Broad spectrum antibacterials are active against the Gram-negative and Gram-positive organisms.

For example phenicols, tetracyclines.

Semisynthetic drugs -

As known as the partial chemical synthesis, it is a type of chemical synthesis that uses chemical compounds which are isolated from any natural source.

Semisynthesis is a cheaper method, as the initial substance is extracted from nature and rest few steps require chemical, which make it cheap and quicker process of drug synthesis.
