Description
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.
