MedKoo CAT#: 555259
CAS#: 22816-60-0 (HCl)
Description: A22 is an inhibitor of MreB, an actin-like bacterial protein, and has been shown to act as an antiobiotic adjuvant. A22 inhibition of MreB disrupts the bacterial actin cytoskeleton, which can cause an increase in cell permeability and altered transport.
