Description

A kind of Oligopoly thiophene derivative and application thereof
Technical field
The invention belongs to sulfur heterocyclic compound, be specifically related to thiophene and derivatives.
Background technology
Influenza infection is firstly the need of entering target cell.As enveloped virus, influenza virus enters the process of target cell needs film The mediation of glycoprotein.The envelope protein that influenza virus mediation film merges is hemagglutinin (Hemagglutinin, HA).HA is by HA1 With two subunit compositions of HA2.HA1 has 328 amino acid residues, and HA2 has 221 amino acid residues.HA1 and target cell membrane On sialic acid receptor combine, then virus is entered Cytoplasm by pinocytosis, and is wrapped in endosome (endosome).HA2 It is then cross-film subunit, mediate retroviral film and the fusion of endosome film.Under the low ph conditions within endosome, HA2 occurred conformation Change, form the Six helix bundle structure of a kind " hair fastener ", so that viromembrane merges with endosome film, formed and merge hole (fusion pore), the nucleic acid of virus enters in the endochylema of cell from fusion hole, it is achieved the infection of virus.
Influenza virus entry inhibitor is the Tamiflu that a class is novel, and the commitment in virus infection interrupts the link of duplication, Reduce plasma viral load, there is obvious superiority.
There is presently no influenza virus entry inhibitor in the whole world on a large scale for influenza preventing and treating (Pharm Res.1999,16 (7): 1041~1046).The little molecular flow Influenza Virus entry inhibitor majority of document report is to be become by the HA conformation suppressing low pH induction Changing and play antivirus action, wherein representative compound is Stachyflin.Experiment in vitro confirms, this compound can stablize HA Conformation under conditions of neutral ph.But the antiviral activity of Stachyflin is the highest, and action site is the clearest and the most definite.1997, beautiful BMS drugmaker of state reports the micromolecular compound BMY-27709 of a HA conformation change that low pH can be suppressed to induce (Bioorg.Med.Chem.Lett.2000,18 (10): 1649-1652.), reports active higher similar compound subsequently BMS-199945 and BMS-201160, its IC50Respectively reach 0.57 and 1.1 μM, and prove that it is made by the method for photoaffinity labeling It is HA2 (PNAS.2008,46 (105): 17736-17741) with target spot, around fusogenic peptide, has a hydrophobic pocket, with Time the structure of these reactive compounds imitated analyzed, the methoxyl group of its precursor structure salicylic acid 2 is most important, separately to activity External 5 introduce lipophilic group such as-CH3,-Cl ,-F or-CF3The help having had inhibitory activity, if 3 introducings The group such as-CN ,-NO of polarity2Derivant does not then have activity.Recently Evelien (J Virol.2010,84 (9): 4,277 4288) and Song etc. (An tiviral Res.2007,76 (2): 178-185.) report some micromolecular compounds can act on virus infection Starting stage, the virus fusion of suppression HA mediation.With salicylic acid compounds have similar structures compound CL-61917, CL-385319, CL-62554 have the effect (J Virol.1999,73 (3): 1785-1794) that suppression influenza A virus enters. 2011, Tang Guozhi (J Virol.1998,248 (2): 264 274) etc. reported bigcatkin willow amido entry inhibitor, by inciting somebody to action Hydroxyl on phenyl ring becomes sulfonamide or chlorine atom, and activity significantly improves, and reaches nM rank, and its mechanism is by little point Sub-inhibitor is combined with the HA of H1N1 hemagglutinin, stops the conformation of its reproduction process to change, thus reaches suppression disease The purpose that poison enters.
Changing relative to suppression HA2 conformation under low ph conditions, some compounds can carry out changing before film merges in virus The pH environment of cytoplasm matter, so that HA2 conformation can not change, reaches to suppress the purpose of cell entry, such as podocarpic acid. Equally, podocarpic acid series compound is active to H1, H2 type virus, to H3 and the best (ACS of inhibition of Type B virus Med.Chem.Lett.2011,2,603–607)。
2009, Yingxia Li (J.Med.Chem.2009,52 (23): 7368-7371.) reported first glycosides element series derivatives Thing can suppress H5N1 virus to enter host cell;2012, its seminar (Eur.J.Med.Chem.2012,53,316-326.) Report again many glucosides prime system row derivant, best inhibitory activity IC50Between 6.00-9.25 μM, its mechanism is sugar in glycosides element Chain and aglycone interference hemagglutinin HA are combined with the sialic acid of host cell surface, thus reach to suppress H5N1 virus Enter the purpose of host cell.2011, we report CL-385319 had inhibitory action (Eur to H5N1 type influenza virus J Pharmacol.2011,660 (2-3): 460-467.), its IC50Value is 27.03 ± 2.54 μMs;Within 2012, our seminar reports again CL-385319 Yu HA2 effect is " induced-fit " process (PLOS ONE.2012,7 (8): e41956.);By right CL-385319 tentatively changes structure, finds that little molecule 1l is than the piperidines micromolecular higher (Eur.J of inhibitory action to H5N1 virus Med.Chem.2012,57,211-216.).Oligopoly thiophene, as small molecule compound, there are no document and reports that it suppresses The effect that influenza enters.

3, the activity experiment of In Vitro Anti H1N1 bird flu live virus
With every hole 2.5 × 104Individual mdck cell kind plate is in 96 orifice plates, and at 37 DEG C of 5%CO2Under the conditions of cultivate 24h.A type The testing compound of H1N1 influenza virus PR8 and the 2 times of dilutions of 7 Concentraton gradient hatches 1h altogether in 37 DEG C, and initial concentration is 8-200μM.After PBS mdck cell 2 times, infect adherent cell with aforementioned viral-medicinal mixture in 37 DEG C 1h, abandons supernatant, changes the culture medium continuation cultivation 48h processing pancreatin containing respective concentration testing compound and 1 μ g/ml TPCK. Use the yield of neuraminidase (NA) activity experiment detection culture supernatant generation of neutrons virus.Summary process is as follows, by cultivation Be transferred to clearly 96 hole blackboards, and with 20 μMs of 2-(4-Methylumbelliferyl-a-D-N-acetylneuraminic acid sodium Salt (MUNANA, Sigma, cat.No M8639), 33mM 2-[N-morpholino] ethanesulfonic acid (pH 6.5), 4mM CaCl21h is hatched at 37 degree.Then reaction is terminated with 0.14M NaOH (83% ethanol).Use microplate reader (Genios Pro, Tecan, US) fluorescence intensity, excitation wavelength is 340nm, a length of 535nm of transmitted wave.Use Reed-Muench Method [Reed, L.J., Muench, H., 1938.A simple method of estimating fifty percent endpoint.Am.J. Hyg.27,493-497] calculate the IC50 that Drug inhibition is viral, i.e. cause viral yield to reduce by the drug level of 50%. CL-385319 is as positive control drug.The results are shown in Table 2.
Table 2 part Oligopoly thiophene derivative anti-H1N1 live virus activity
