A series of 1-phenyl-3-(1-phenylethyl)urea derivatives were identified as novel and potent complement inhibitors through structural modification of the original compound from high-throughput screening. Various analogues (7 and 13-15) were synthesized and identified as complement inhibitors, with the introduction of a five- or six-carbon chain (7c, 7d, 7k, 7l, and 7o) greatly improving their activity. Optimized compound 7l has an excellent inhibition activity with IC50 values as low as 13 nM. We demonstrated that the compound 7l inhibited C9 deposition through the classical, the lectin, and the alternative pathways but had no influence on C3 and C4 depositions.

The synthesis and phosphodiesterase (PDE) inhibitory profile of a series of imidazopyridines, including sulmazole and isomazole, on separated PDE isoenzymes are described.The results show that both sulmazole and isomazole are weak inhibitors of PDE III, and their inotropic activity is unlikely to be due to PDE III inhibition alone.Surprisingly, both compounds were found to be significant inhibitors of the cGMP specific isoenzyme, PDE V, and a series of simple 2-substituted phenylimidazopyridines have been made to investigate the SAR of PDE activity.This has been shown to be sensitive to chain length, polarity, and the nature of the heteroatom linking group.Potent PDE V inhibitors, many of which are also significant inhibitors of PDE IV, have been identified.
