Clindamycin phosphate hydrochloride (Clindamycin 2-phosphate), a broad-spectrum bacteriostatic lincosamide antibiotic, serves as a prodrug of Clindamycin. It lacks antimicrobial activity in vitro; however, through phosphatase ester hydrolysis, it is rapidly converted to the active form, Clindamycin, in vivo. This compound is utilized in the research of acne and bacterial vaginosis [1] [2] [3].
