Terreic acid, a quinone epoxide antibiotic, acts as an effective Btk inhibitor. Terreic acid blocks the interaction between PKC and the pleckstrin homology domain of Btk. Terreic acid inhibits the binding of GST-BtkPH to PKC in lysates of HMC-1 human mast cells with an IC50 of approximately 100 μM[1].

| In Vitro | Terreic acid inhibits the association of Btk with PKCβII in mouse mast cells at lower concentrations (IC50 of ≈30 μM). Terreic acid inhibits the catalytic activity of Btk but not PKC[1]. Terreic acid (pretreatment for 30 min before stimulation by antigen for 3 min) inhibits both the basal and activation levels of Btk autophosphorylating activity with IC50s of 10 μM and 3 μM, respectively[1]. Terreic acid inhibits the autophosphorylating activity of Btk purified partially from recombinant baculovirus-infected Sf9 insect cells in a dose-dependent manner[1]. Western Blot Analysis[1] Cell Line: Mouse bone marrow-derived mast cells Concentration: 0, 5, 10, 20 μM Incubation Time: Pretreated for 30 min Result: Inhibited both the basal and activation levels of Btk autophosphorylating activity in a dose-dependent manner. |
| In Vivo | Terreic acid inhibits the late-phase response of in vivo allergic cutaneous reactions[1]. Animal Model: BALB/c mice[1] Dosage: 0, 0.15, 1.5, and 15 mg/kg Administration: Injected i.p. 1 hr before antigen challenge. Ear thicknesses were measured at 1 hr and 24 hr Result: The early response, as examined 1 hr after antigen challenge, was not affected by TA. In contrast, TA inhibited the late-phase (24 hr) response in a dose-dependent manner. |
