chemical structure of neopeltolide, leading to the synthesis of a series of new neopeltolide derivatives with much simpler chemical structures. The calculated binding energies (ΔGcal) of the newly synthesized analogues correlated very well (R2 = 0.90) with their experimental binding free energies (ΔGexp), which confirmed that the computational protocol was reliable.

potency. Similarly, inhibitory activities were lost when the CO2H moiety at the 2-position was moved to the 3- or 4-position on the terminal benzene. These observations suggest that the conformation around the anthranilic acid moiety affects the inhibitory activities toward IgE biosynthesis. 2-(4-(2-Naphthyloxy)benzamido)benzoic acid (29) seemed to be a more potent inhibitor of IgE production than of IgG
