Eur J Pharmacol 2020; 884:173327. [PMID: 32726656 DOI: 10.1016/j.ejphar.2020.173327] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/11/2019] [Revised: 06/25/2020] [Accepted: 06/26/2020] [Indexed: 11/26/2022]
Abstract
AIDS, a serious fatal disease caused by the human immunodeficiency virus (HIV), is an epidemic disease for which no effective vaccine has been established. The current therapeutic interventions for AIDS have limited efficacy because they are unable to clear HIV infections and the continuous occurrence of resistant HIV strains. Therefore, the exploitation of new drugs to prevent the spread of AIDS remains a high priority. In this study, the effects of icariin and its metabolite anhydroicaritin on SIV/HIV replication were investigated. In CEM × 174 cells and PBMC cells, both icariin and anhydroicaritin can significantly inhibit HIV-1 or SIVmac251 replication. Furthermore, molecular docking studies revealed that icariin and anhydroicaritin can act on both HIV reverse transcriptase and protease but could not bind to integrase. Reverse transcriptase and protease inhibition biological assays showed that both icariin and anhydroicaritin could significantly inhibit only HIV reverse transcriptase. In summary, the two compounds can significantly inhibit HIV/SIV in vitro and their targets may be mainly involved with HIV reverse transcriptase.

Abstract
A low-cost rodent model of HIV infection and which presents high application value is an effective tool to investigate HIV infection and pathogenesis. However, development of such a small animal model has been hampered by the unsuitability of rodent cells for HIV-1 replication given that the retrovirus HIV-1 has high selectivity to its host cell. Our study used the mouse leukemia cell lines L615 and L1210 that were induced by murine leukemia virus and transfected with hCD4/CCR5 loaded-lentiviral vector. Lentiviral vectors containing the genes hCD4/CCR5 under the transcriptional control of cytomegalovirus promoter were designed. Transfection efficiencies of human CD4 and CCR5 in L615 and L1210 cells were analyzed by quantitative real-time polymerase chain reaction (RT-PCR) and Western blot assay. Results showed that hCD4 and CCR5 proteins were expressed on the cell surface, demonstrating that the L615 and L1210 cells were humanized and that they possess the characteristics necessary for HIV infection of human host cells. Moreover, the sensitivity of human CD4/CCR5 transgenic mouse cells to HIV infection was confirmed by RT-PCR and ELISA. Mouse leukemia cell lines that could express hCD4 and CCR5 were thus established to facilitate normal entry of HIV-1 so that a human CD4/CCR5 transgenic mice cell model can be used to investigate the transmission and pathogenesis of HIV/AIDS and potential antiviral drugs against this disease.
