on IL-1β and TNF-α. Herein, 36 novel derivatives were designed and synthesized, and nearly half of the derivatives exhibited much better selectivity on IL-1β releasement inhibition as well as keep similar inhibitory activities to lead compound. In 20 μM, compound 19 exhibited IL-1β releasement inhibitory activity (IC50 = 5.489 μM) which closed to the original compound, and 4.5-fold superior selectivity
