Abstract:
Objective To investigate the inhibiton effect of 4‐styrenesulfonic acid‐co‐maleic acid(PSM ) in HIV‐1 .Methods The inhibition effect of different doses of PSM on HIV‐1 in susceptible cells GHOST (3) X4/Hi5 was observed by Luciferase ,and so did the inhibitory effect of PSM on JR‐FL、HXB2、CNE6 ,CNE30 ,CNE50 ,CNE55 .The cellular toxicity of PSM on the VK2/E6E7 was also evaluated by CCK8 kit .The transcript level of tight junction proteins (ZO‐1 ,E‐cadherin and Occludin) of HEC‐1‐A were analyzed by qRT‐PCR .And then observed the effect of PSM on expression of genitourinary epithelial cells HEC‐1‐A ,so we could e‐valuated the effect of integrity of local mucosal indirectly .Results The results showed that PSM exhibited potent antiviral activity against a broad spectrum of HIV‐1 major isolates with different genotypes and biotypes (EC50 value of JR‐FL ,HXB2 ,CNE6 , CNE30 ,CNE50 ,CNE55 were 5 .78 ,0 .77 ,1 .85 ,3 .15 ,1 .70 ,2 .27 μg/mL respectively) .Meanwhile ,it had less cytotoxicity on VK2/E6E7 .qRT‐PCR showed that no obvious restrain effect on expression of ZO‐1 was observed and PSM increased the level of tran‐scription of E‐cadherin and Occludin .Conclusion PSM may be a potential agent for the prevention of HIV‐1 infection .
