QUINAZOLINONE ANALOGS AND USE OF QUINAZOLINONE ANALOGS
FOR TREATING OR PREVENTING CERTAIN VIRAL INFECTIONS
DESCRIPTION
TECHNICAL FIELD
The present disclosure relates to treating or preventing viral infection from certain
flaviviruses and alphaviruses by administering a therapeutically effective amount of a
quinazolinone analog, pharmaceutically acceptable salt thereof or solvate thereof. The
flaviviruses treated according to this disclosure include Hepatitis C Virus (genotypes 1-7)
and Japanese Encephalitis Virus. Certain of the quinazolinone compounds of the present
disclosure can also be used to treat West Nile Virus. The present disclosure is also related
to certain novel quinazolinone compounds. The subjects treated include humans and
animals.
BACKGROUND OF DISCLOSURE
Flaviviruses and alphaviruses are positive sense RNA viruses and are important
human and/or animal pathogens that can cause acute virus infections with severe diseases
and/or death. Flaviviruses include members of families Flaviviridae including Dengue
Virus (DENV), Murray Valley Encephalitis Virus (MVEV), Saint Louis Encephalitis
Virus (SLEV), West Nile virus (WNV), Japanese Encephalitides Virus (JEV), Yellow
Fever Virus (YFV) and Tick-Borne Encephalitis Virus (TBEV) and Hepciviridae
including Hepatitis C Virus (HCV) and Pestiviruses including Bovine Diarrhea virus
(BVDV). Alphaviruses include Venezuela Equine Encephalitides Virus (VEEV), Eastern
Equine Encephalitis Virus (EEEV), Western Equine Encephalitides virus (WEEV) and
Ross River Virus (RRV). For most arbovirus listed above, there is no effective vaccine or
therapeutics currently available. There are no alphavirus vaccines currently available. The
need to develop antiviral drugs is urgent for developing control measures and treating
these diseases.
Vast amounts of research have accrued over the years related to developing
treatments against viral diseases to inhibit and kill viral infections. Some of this research
5184M-NZ
has resulted in agents approved for clinical use. Nevertheless, efforts continue at an ever-
increasing rate in view of the extreme difficulty in uncovering promising antiviral agents.

The use of N-(2,3-dihydro-1H-indenyl)(4-oxophenyl-3,4-dihydro-
quinazolinyl)thio) acetamide, a compound employed according to the present
disclosure, for treating West Nile Virus has been disclosed. For example, please see
Chung et al. A Cell Based Assay for the Identification of Lead Compounds with Anti-
Viral Activity Against West Nile Virus, Probe Reports from the NIH Molecular Libraries
Program [Internet]. Bethesda (MD): National Center for Biotechnology Information
(US); 2010-2010 Feb 27 [updated 2010 Oct 4], PMID: 21433390 [PubMed]. When N-
(2,3-dihydro-1H-indenyl)(4-oxophenyl-3,4-dihydroquinazolinyl)thio)
acetamide was tested against Hepatitis C Virus, activity was observed (Table 1). Testing
analogs of N-(2,3-dihydro-1H-indenyl)(4-oxophenyl-3,4-dihydroquinazolin
yl)thio) acetamide in cell based virus CPE reduction assays showed Japanese
Encephalitis Virus replication was also inhibited by analogs of N-(2,3-dihydro-1H-inden-
-yl)(4-oxophenyl-3,4-dihydroquinazolinyl)thio) acetamide (Table 2).
Compounds according to the present disclosure can be used in treating Hepatitis C
Virus (genotypes 1-7) (Table 1 and Table 3) and Japanese Encephalitis Virus (Table 2).
In addition certain compounds according to the present disclosure can be used in treating
West Nile Virus (Table 4).
The reduction in HCV was determined with two assays using viral RNA
endpoints. A qPCR analysis and a blot hydridization method were used to show that the
activity is specific for HCV and not the luciferase end-point (Table 4). The data
demonstrated activity in a cell based HCV replicon assay (con 1b). This cell line
expresses a subgenomic section of the HCV genome containing NS2a, NS2b, NS3a,
NS3b, NS4a, NS4b, NS5a and NS5b. However, no activity was observed in biochemical
5184M-NZ
assays: HCV protease (NS3b), HCV helicase, WNV protease (NS2bNS3), and HCV
polymerase (NS5b), these data exclude these proteins as targets of the quinazolinone
activity.

5184M-NZ
formulated as pharmaceuticals for non-pressured preparations, such as in a nebulizer or
an atomizer.
Formulations suitable for parenteral administration include aqueous and non-
aqueous, isotonic sterile injection solutions, which can contain anti-oxidants, buffers,
bacteriostats, and solutes that render the formulation isotonic with the blood of the
intended recipient, and aqueous and non-aqueous sterile suspensions that can include
suspending agents, solubilizers, thickening agents, stabilizers, and preservatives. The
compound can be administered in a physiologically acceptable diluent in a
pharmaceutical carrier, such as a sterile liquid or mixture of liquids, including water,
saline, aqueous dextrose and related sugar solutions, an alcohol, such as ethanol,
isopropanol, or hexadecyl alcohol, glycols, such as propylene glycol or polyethylene
glycol such as poly(ethyleneglycol) 400, glycerol ketals, such as 2,2-dimethyl-1,3-
dioxolanemethanol, ethers, an oil, a fatty acid, a fatty acid ester or glyceride, or an
acetylated fatty acid glyceride with or without the addition of a pharmaceutically
acceptable surfactant, such as a soap or a detergent, suspending agent, such as pectin,
carbomers, methylcellulose, hydroxypropylmethylcellulose, or carboxymethylcellulose,
or emulsifying agents and other pharmaceutical adjuvants.

vegetable, or synthetic oils. Specific examples of oils include peanut, soybean, sesame,
cottonseed, corn, olive, petrolatum, and mineral. Suitable fatty acids for use in parenteral
formulations include oleic acid, stearic acid, and isostearic acid. Ethyl oleate and isopropyl
myristate are examples of suitable fatty acid esters. Suitable soaps for use in parenteral
formulations include fatty alkali metal, ammonium, and triethanolamine salts, and suitable
detergents include (a) cationic detergents such as, for example, dimethyldialkylammonium
halides, and alkylpyridinium halides, (b) anionic detergents such as, for example, alkyl, aryl,
and olefin sulfonates, alkyl, olefin, ether, and monoglyceride sulfates, and sulfosuccinates,
(c) nonionic detergents such as, for example, fatty amine oxides, fatty acid alkanolamides,
and polyoxyethylene polypropylene copolymers, (d) amphoteric detergents such as, for
example, alkyl ß-aminopropionates, and 2-alkylimidazoline quaternary ammonium salts,
and (e) mixtures thereof.
5184M-NZ
The parenteral formulations typically contain from about 0.5% to about 25% by
weight of the active ingredient in solution. Suitable preservatives and buffers can be used
in such formulations. In order to minimize or eliminate irritation at the site of injection,
such compositions may contain one or more nonionic surfactants having a hydrophile-
lipophile balance (HLB) of from about 12 to about 17. The quantity of surfactant in such
formulations ranges from about 5% to about 15% by weight. Suitable surfactants include
polyethylene sorbitan fatty acid esters, such as sorbitan monooleate and the high
molecular weight adducts of ethylene oxide with a hydrophobic base, formed by the
condensation of propylene oxide with propylene glycol.
Pharmaceutically acceptable excipients are also well-known to those who are
skilled in the art. The choice of excipient will be determined in part by the particular
compound, as well as by the particular method used to administer the composition.
Accordingly, there is a wide variety of suitable formulations of the pharmaceutical
composition of the present disclosure. The following methods and excipients are merely
exemplary and are in no way limiting. The pharmaceutically acceptable excipients
preferably do not interfere with the action of the active ingredients and do not cause
adverse side-effects. Suitable carriers and excipients include solvents such as water,
alcohol, and propylene glycol, solid absorbents and diluents, surface active agents,
suspending agent, tableting binders, lubricants, flavors, and coloring agents.
The formulations can be presented in unit-dose or multi-dose sealed containers,
such as ampules and vials, and can be stored in a freeze-dried (lyophilized) condition
requiring only the addition of the sterile liquid excipient, for example, water, for
injections, immediately prior to use. Extemporaneous injection solutions and suspensions
can be prepared from sterile powders, granules, and tablets. The requirements for
effective pharmaceutical carriers for injectable compositions are well known to those of
ordinary skill in the art. See Pharmaceutics and Pharmacy Practice, J.B. Lippincott Co.,
Philadelphia, PA, Banker and Chalmers, Eds., 238-250 (1982) and ASHP Handbook on

comprising the active ingredient in an inert base, such as gelatin and glycerin, or sucrose
and acacia; and mouthwashes comprising the active ingredient in a suitable liquid carrier;
as well as creams, emulsions, and gels containing, in addition to the active ingredient,
such carriers as are known in the art.
Additionally, formulations suitable for rectal administration may be presented as
suppositories by mixing with a variety of bases such as emulsifying bases or water-
soluble bases. Formulations suitable for vaginal administration may be presented as
pessaries, tampons, creams, gels, pastes, foams, or spray formulas containing, in addition
to the active ingredient, such carriers as are known in the art to be appropriate.
Suitable pharmaceutical carriers are described in Remington’s Pharmaceutical
Sciences, Mack Publishing Company, a standard reference text in this field.
The dose administered to an animal, particularly a human, in the context of the
present disclosure should be sufficient to affect a therapeutic response in the animal over
a reasonable time frame. One skilled in the art will recognize that dosage will depend
upon a variety of factors including a condition of the animal, the body weight of the
animal, as well as the severity and stage of the condition being treated.
A suitable dose is that which will result in a concentration of the active agent in a
patient which is known to affect the desired response. The preferred dosage is the
amount which results in maximum inhibition of the condition being treated, without
unmanageable side effects.
The size of the dose also will be determined by the route, timing and frequency of
administration as well as the existence, nature, and extend of any adverse side effects that
might accompany the administration of the compound and the desired physiological
effect.
Useful pharmaceutical dosage forms for administration of the compounds according
to the present disclosure can be illustrated as follows:
5184M-NZ
Hard Shell Capsules
A large number of unit capsules are prepared by filling standard two-piece hard
gelatine capsules each with 100 mg of powdered active ingredient, 150 mg of lactose, 50 mg
of cellulose and 6 mg of magnesium stearate.
Soft Gelatin Capsules
A mixture of active ingredient in a digestible oil such as soybean oil, cottonseed oil
or olive oil is prepared and injected by means of a positive displacement pump into molten
gelatin to form soft gelatin capsules containing 100 mg of the active ingredient. The
capsules are washed and dried. The active ingredient can be dissolved in a mixture of
polyethylene glycol, glycerin and sorbitol to prepare a water miscible medicine mix.
Tablets
A large number of tablets are prepared by conventional procedures so that the
dosage unit was 100 mg of active ingredient, 0.2 mg. of colloidal silicon dioxide, 5 mg of
magnesium stearate, 275 mg of microcrystalline cellulose, 11 mg. of starch, and 98.8 mg of
lactose. Appropriate aqueous and non-aqueous coatings may be applied to increase
palatability, improve elegance and stability or delay absorption.
Immediate Release Tablets/Capsules
These are solid oral dosage forms made by conventional and novel processes.
These units are taken orally without water for immediate dissolution and delivery of the
medication. The active ingredient is mixed in a liquid containing ingredient such as
sugar, gelatin, pectin and sweeteners. These liquids are solidified into solid tablets or
caplets by freeze drying and solid state extraction techniques. The drug compounds may
be compressed with viscoelastic and thermoelastic sugars and polymers or effervescent
components to produce porous matrices intended for immediate release, without the need
of water.
Moreover, the compounds of the present disclosure can be administered in the
