| Abstract: | It has been reported that some tilorone analogs can inhibit silicotic fibrosis in rats. Xinin, a new antisilicotic drug among these analogs, possesses good antifibrotic potency. The object of the present study was to determine the effects of four tilorone analogs (such as Xinin, Tilorone, 1331 and 1330) on rat alveolar macrophages (AM) in vitro. These drugs (40 μmol/L) reacted with AM in 30 min did not affect cell viability. The results showed that Xinin significantly inhibited zymosan-induced activation of the respiratory burst. It is in vitro a potent inhibitor of zymosan-stimulated oxysen consumption, superoxide anion release, hydrogen peroxide and chemiluminescence production by AM. In addition, binding of Xinin to AM was time and dose dependent. The sequence for bindining affinity was Xinin>Tilorone>1331>1330. The ability of these drugs to modify AM function in vitro correlated with their antifibrotic potency in vivo. |
