HIV-1 integrase inhibitor is useful for anti-HIV, with IC50 value of 0.33 µM,[1] which can target HIV-1 integrase and depress the activity in the treatment of HIV infection, AIDS, and other similar diseases characterized by integration of a retroviral genome into a host chromosome.HIV integrase is a 32 kDa protein produced from the C-terminal portion of the Pol gene product, an enzyme produced by HIV that enables its genetic material to be integrated into the DNA of the infected cell [2]which are not to be confused with phage integrases and a key component in the retroviral pre-integration complex (PIC)[3]. HIV-1 integrase is composed of 3 structurally independent, functional domains: the N-terminal domain (NTD), catalytic core domain (CCD) and the C-terminal domain (CTD).The HIV-1 integration occurs through a multistep process that includes two catalytic reactions: 3’endonucleolytic processing of proviral DNA ends (termed 3’processing) and integration of 3’-processed viral DNA into cellular DNA (referred to as strand transfer)[4].The human immunodeficiency virus (HIV) is the causative agent for the acquired immunodeficiency syndrome (AIDS)[5], then HIV integrase is an attractive target for new anti-HIV drugs. The drug design of HIV-1 integrase inhibitor include integrase strand transfer inhibitors (INSTIs),inhibition of the LEDGF/p75- integrase interaction and integrase binding inhibitors, but strand transfer inhibition is the most intuitively obvious and readily pursued to date.Mg2+ and Mn2+ are critical cofactors in the integration phase, so removing these cofactors (e.g. through chelation) causes functional impairment of integrase[6].Competitive inhibitors compete directly with viral DNA for binding to integrase in order to inhibit 3‘-end processing.[7] In doing this the inhibitors completely block the active site from binding to target DNA.INSTIs bind tightly and specifically to the IN that is associated with the ends of the DNA by chelating the divalent metal ions (Mg2+) which is coordinated by the catalytic triad, such as the DDE motif which is located in the CCD and is the active site of the enzyme[8].Development of a successful INSTI treatment was accomplished when raltegravir was discovered by Merck Sharp & Dohme Limited.[9] S/GSK1349572 is an integrase inhibitor discovered by ViiV/Shinongi which was entering phase three in clinical trials in 2011. This new drug is promising and seems to be well tolerated and so far shows better results than both raltegravir and elvitegravir.[10]References:1.Loizidou EZ et al.

各位大侠：小弟最近做个长片段的CDNA与T载体的连接，片段大小6.4K，载体选用的是pUC19和pGEMT-easy,反转录酶用的是RevertAidTirstStrandcDNASynthesisKit(#K1621)，CDNA第二链的扩增用的是LATaq。我是用纯病毒的RNA做模板，操作步骤严格按照说明做的，也曾经有一次获得过电泳图清晰显示的是全长6.4KB左右的片段，与载体连接，结果筛选到的几个克隆，插入的片段仅有2KB左右，奈何？可最近几次再用此反转录试剂盒却不能得到所需片段。在此，小弟想问问大家，你们是否遇到同样的问题，是如何解决的？所用的试剂（载体和酶的选择）和方法是什么，可以告诉后来者，共同进步吧。
