As of my last update in October 2023, there is no specific information available regarding the chemical substance with the name "INDEX NAME NOT YET ASSIGNED" and CAS number 2699607-22-0. This may indicate that the substance is either newly synthesized, not widely studied, or not yet characterized in the scientific literature. Typically, chemical substances are identified by their molecular structure, physical properties (such as melting point, boiling point, and solubility), and chemical behavior (reactivity, stability, etc.). For newly assigned CAS numbers, detailed information may become available as research progresses and as regulatory bodies or scientific communities publish findings. If you are looking for specific characteristics or applications of this substance, it may be beneficial to consult databases or publications that focus on emerging chemicals or to reach out to chemical suppliers or research institutions that may have access to proprietary data.

Penicillin V-d

Penicillin V also inhibits growth of
S. aureus in vitro
(MIC = 0.016 mg/L) and
in vivo
in a thigh model of infection in mice.

It inhibits the growth of
S. pyogenes
in mice following one or two dose therapy with curative dose (CD
50
) values of 0.207 and 0.031 mg, respectively.
4
Penicillin V (100 mg/kg per day, p.o.) prevents experimental acute otitis media in rats when administered prior to infection by pneumococci.
5
Formulations containing penicillin V have been used to treat bacterial infections of the skin, throat, ear, mouth, and respiratory tract.
