Which of the following antimicrobials is NOT classified as a type I calcimimetic that mimics calcium's action on the calcium-sensing receptor to suppress parathyroid hormone (PTH) secretion?

Explanation

Type I calcimimetics are antimicrobials that imitate calcium's stimulatory effect on the calcium-sensing receptor, thereby reducing PTH release from the parathyroid gland. Streptomycin, Neomycin, and Gentamicin fall into this category, whereas Hamycin does not exhibit this property.
