Rv1625c agonist V-59

Rv1625c agonist V-59 (V-59) is a specific small molecule agonist of the Mtb adenylyl cyclase Rv1625c, inhibits Mtb growth in macrophages (EC50=0.3 uM) in an Rv1625c-dependent mechanism.V-59 inhibits Mtb growth in cholesterol media (EC50 0.70 uM), but not in media containing the two-carbon fatty acid acetate, or in standard rich growth media.V-59 stimulates Rv1625c to produce cAMP, which is necessary for V-59 to inhibit Mtb growth.Chemically activating Rv1625c via V-59 preferentially inhibits cholesterol utilization in WT Mtb, rather than equally inhibiting all lipid utilization by the bacterium.
