Definitions

  • This invention relates to antiviral compounds, pharmaceutical compositions thereof, and a method of treating viral infections. More specifically, this invention relates to certain indolizino[ l,2-b]-quinolinyl derivatives which have antiviral activity.
  • Camptothecin is an example of one such compound. It is a water-insoluble, cytotoxic alkaloid produced by Camptotheca acuminata trees indigenous to China and Nothapodytes foetida trees indigenous to India. Camptothecin and its close congeners are known to inhibit eukaryotic topoisomerase I. The cytotoxic and antitumor activity of camptothecin and its close congeners is due to this inhibition of eukaryotic topoisomerase I (Cancer Res. 1988, 48, 1722; Molec. Pharmacol.
  • camptothecin has been shown to have an effect on viruses by a number of investigators in laboratory settings.
  • camptothecin Although camptothecin has demonstrated antiviral activity in in vitro tissue culture systems, camptothecin and its close analogs that have a hydroxylactone moiety cannot be considered as useful in vivo antiviral agents because they inhibit mammalian topoisomerase I, inhibit host cell DNA replication, and are cytotoxic to mammalian cells. Furthermore, camptothecin is not expected to be attractive for drug development as an antiviral agent because of unacceptable dose-limiting toxicity, unpredictable toxicity, poor aqueous solubility, and/or unacceptable shelf life stability.
  • the present invention provides a method for treating viral infections, which method comprises administering to an infected host in need thereof an effective amount of a compound of Formula I, or a pharmaceutically acceptable salt thereof, alone or in combination with a carrier, diluent or excipient.
  • R O, -OH, and OR 1 ;
  • Rl is -COR 4 , or -P(O)(OH)R 5 wherein:
  • R3 is -H or lower alkyl
  • R 4 is -CR 3 R 6 R 7 ;
  • R 5 is OH or CH NH 2 ;
  • R6 is H or the side chain of any naturally occuring ⁇ -amino acid
  • R7 is -NR9RlO . . _ - v_ whe _ e X is any pharmaceutically acceptable anion
  • R8 is lower alkyl
  • R9 and R 1 ⁇ are independently selected from the group consisting of -H, -Cl-6 alkyl, and R ⁇ and R 1 ⁇ taken together to form a 5-7 membered saturated heterocyclic ring containing the nitrogen on which R ⁇ and R 1 ⁇ are substituted; and R 11 is -CH 2 R 12 , wherein:
  • R 12 is -N(CH 3 ) 2 ⁇ ' ⁇ /
  • this invention relates to novel compounds of Formula I, and pharmaceutically acceptable salts thereof.
  • this invention relates to a composition
  • a composition comprising a novel compound of Formula I in combination with an acceptable carrier, excipient or diluent, particularly a pharmaceutically acceptable carrier, excipient or diluent
  • Aliphatic is intended to include saturated and unsaturated radicals. This includes normal and branched chains, saturated or mono or poly unsaturated chains where both double and triple bonds may be present in any combination.
  • the phrases "lower alkyl” and “C1-.5 alkyl” refer to and mean an alkyl group of 1 to 6 carbon atoms in any isomeric form, but particularly the normal or linear form.
  • Lower alkoxy means the group lower alkyl-O-.
  • Halo means fluoro, chloro, bromo or iodo.
  • Acyl means the radical having a terminal carbonyl carbon.
  • 5-7 membered saturated heterocyclic ring containing the nitrogen is intended to include saturated rings such as piperidine, pyrrolidine, morpholine, piperazine, and N-alkyl piperazine.
  • Salts of any sort may be made from these compounds, provided there is an acidic group present or a sufficiently basic nitrogen.
  • Particularly preferred are the pharmaceutically acceptable salts of the instant compounds. These latter salts are those which are acceptable in their application to a pharmaceutical use. By that it is meant that the salt will retain the biological activity of the parent compound and the salt will not have untoward or deleterious effects in its application and use in treating diseases. .
  • compositions are prepared in a standard manner.
  • the parent compound in a suitable solvent is reacted with an excess of an organic or inorganic acid, in the case of acid addition salts of a base moiety, or an excess of organic or inorganic base in the case where there is an acid group.
  • Representative acids are hydrochloric acid, hydrobromic acid, sulfuric acid, phosphoric acid, acetic acid, maleic acid, succinic acid or methanesulfonic acid.
  • Cationic salts are readily prepared from metal bases such as sodium, potassium, calcium, magnesium, zinc, copper or the like and ammonia.
  • Organic bases include the mono or disubstituted amines, ethylenediamine, piperazine, amino acids, caffeine, and the like.
  • the ring system of the compounds of the present invention are numbered according to Formula II.
  • a chiral center or another form of an isomeric center is created by some combination of substituents, in a compound of the present invention, all forms of such isomer(s) are intended to be covered herein.
  • Inventive compounds containing a chiral center may be used as a racemic mixture or the mixture may be separated and an individual enantiomer may be used alone.
  • the present invention provides a method for the treatment of viral infections caused by certain DNA viruses comprising administering to an infected animal, preferably a mammal, most preferably a human, in need thereof an effective amount of a compound of Formula I as described hereinabove, or a pharmaceutically acceptable salt thereof, alone or in combination with a carrier, excipient or diluent

  • Starting materials are commercially available or can be made by published methods.
  • the reaction sequences are illustrated by Schemes I-i ⁇ .
  • 2-pyrrolidone 1 can be alkylated with dimethyl sulfate to give ether 2 which can be condensed with acetonedicarboxylate to give indolizine 3.
  • Methylation of 3 with methyl iodide at ambient temperature in the inert solvent produced 4 which can be hydrolyzed with an aqueous base to give 5 followed by decarboxylation to produce 6.
  • Compound 10 can be oxidized using Davis reagent and base to give alcohol 11 which can be further oxidized with pyridiniumchlorochromate in methylene chloride to give ketone-ketal 12.
  • the assay used to test the compounds of the present invention for antiviral activity is well-known. A generalized description of the assay follows.
  • Well plates are seeded with the appropriate cells at a concentration of lxl 0 ⁇ cells per well suspended in 0.5 mL of Earle's Minimum Essential Medium (EMEM) containing 10% fetal bovine serum (FBS) and antibiotic and antimycotic solution.
