Description

METHOD AND COMPOSITION FOR PROPHYLAXIS AND TREATMENT OF
SYMPTOMS ASSOCIATED WITH COLD AND INFLUENZA-LIKE
ILLNESSES
FIELD
The present invention relates to a novel therapeutic use of stilbenic phytoalexins. More specifically, the embodiments of the present invention relate to the prophylaxis and treatment of symptoms associated with cold and influenza-like illnesses and the prophylaxis and treatment of congestion associated with respiratory afflictions.
BACKGROUND
~5 It is known that many different viruses and viral strains induce symptoms associated with respiratory viral infections. For example, the common cold and flu are caused by members of several families of viruses including influenza, parainfluenza viruses, rhinoviruses, respiratory syncytial viruses, enteroviruses, and coronaviruses. Pinpointing the specific cause of the illness is difficult and 2o not practical since there are also a number of predisposing factors whose contribution to the manifestation of symptoms is not fully understood. Such factors include, but are not limited to, physical fatigue, psychological stress, and overall physical healthiness.
Regardless of the virus and associated factors leading to the onset of cold 25 and influenza symptoms, a number of remedies to alleviate the symptoms of the common cold have been suggested. The cough/cold products that are currently marketed typically contain one or more of the following actives: nasal decongestants such as pseudoephedrine, oxymetazoline, antihistamines such as doxylamine, antitussives such as dextromethorphan, expectorants such as so guaifenesin and antipyretics such as acetaminophen. In an attempt to improve existing cold remedies, experts in the field have suggested several alternative pharmacotherapies and subsequently conducted cold trials to test their efficacy.

Examples of these therapies include the use of interferon-a2 , see Douglas et al., Prophylactic Efficac roof Intranasal Alpha2- Interferon Against Rhinovirus Infection in the Family Setting, The New England Journal of Medicine, 314, pp. 65-70, 1986; bradykinin antagonist, see Higgins et al., A Study of the Efficacy of the BrandYkinin Antagonist NPC567 in Rhinovirus Infections in Human Volunteers, Antiviral Research vol. _14, pp. 339-344, 1990; glucocorticoid, see Farr et al., A
Randomized Controlled Trial of Glucocorticoid Prophylaxis Against Experimental Rhinovirus Infection, The Journal of Infectious Diseases vol. 162, pp. 1173-1177, 1990; nedocromil, see Barrow et al., The Effect of Intranasal Nedocromil Sodium on Viral Upper Re~iratory Tract Infections in Human Volunteers, Clinical and Experimental Allergy vol. 20, pp. 45-51, 1990; a combination of interferon-a2, ipratropium and naproxen, see Gwaltney; Combined Antiviral and Antimediator Treatment of Rhinovirus Colds, The Journal of Infectious Diseases vol. 166, pp.
776-782, 1992; and zinc salts, see Potter et al., DIAS Rounds Zinc Lozenges for 15 Treatment of Common Colds, The Annals of Pharmacotherapy vol. 27, pp. 589-592, 1993.
A number of patents have also been issued disclosing compositions for the treatment of the common cold and flu symptoms and their methods of use. A
sample of such patents include: U.S. Patents 5,240,694; 5,422,097, and 20 5,492,689, all to Gwaltney, disclosing treatment using combinations of antiviral and antiinflammatory compounds; U.S. Patents RE033,465 and 5,409,905, both to Eby disclosing treatment using zinc salts; and U.S. Patents 4,619,934 and 4,552,899, both to Sunshine, disclosing treatment of cough and colds using compositions comprising non-steroidal antiinflammatory drugs such as NSAIDS
25 with antihistaminically effective materials such as chlorpheniramine.
Despite the abundance of compositions and preventative treatments known in the art, there remains a need to provide a consistent, effective, and safe method for the prophylaxis and treatment of cold and influenza-like symptoms as well as treatment of congestion associated with respiratory afflictions.
so As discussed in detail below, Applicants have discovered new means for the prophylaxis and treatment of cold and influenza-like symptoms as well as treatment of congestion associated with respiratory afflictions via administration of certain stilbenic phytoalexins.
Phytoalexins are defense substances with antimicrobial properties which are produced by plants after infections. They include various groups of natural s substances (e.g., isoflavonoids, terpenoids, polyacetylenes and dihydrophenanthrenes). Different sources of phytoalexin include the roots of Veratrum grandiflorum, the bark of Pinus sibirica, Vitis vinifera, and Arachis hypogaea. Other sources include Eucalyptus, Polygonum and Nothofagus species and Cudrania javanensis. Phytoalexins can also exist naturally as an oligomer.
Compositions comprising stilbenic phytoalexins can be prepared either utilizing natural occurring sources of stilbenic phytoalexins or synthesizing stilbenic phytoalexins. One type of stilbenic phytoalexin that can be found in a variety of naturally occurring sources is 3,4',5-trihydroxystilbene resveratrol.
15 Reservatrols are found in relatively large amounts in red grapes and red wine and implicated for favorable pharmacological effects that include the prevention and therapy of atherosclerosis. Research conducted on the components present in red wine that exert pharmacological effects indicates 3,4',5-trihydroxystilbene resveratrol's protective effects at the cardiovascular level. See, for example, 2o Frankel E. N., et al., 341 Lancet 454, 1993. Recently, it has been demonstrated that 3,4',5-trihydroxystilbene resveratrol has activity as a cancer chemopreventive (Meishang Jang et al., 275 Science 218-229, 1997). The dietary supplement Huzhang, a source of resveratrol, is reported to have antioxidant properties (product label for Resveratrol from "Source Naturals," 1997).

The present invention is directed to methods for the prophylaxis and treatment of cold and influenza-like symptoms and/or treatment of congestion associated with respiratory afflictions comprising administering to a subject a composition having a stilbenic phytoalexin having the structure:

wherein R', R2, R3, R4, R5, and R6 are independently selected from hydrogen and hyd roxy.
The present invention is further directed to compositions including the above stilbenic phytoalexin.
DETAILED DESCRIPTION
While the specification concludes with claims which particularly point out and distinctly claim the invention, it is believed the present invention will be better understood from the following description.
All cited references are incorporated herein by reference in their entireties.
Citation of any reference is not an admission regarding any determination as to its availability as prior art to the claimed invention.
All percentages are by weight of total composition unless specifically stated otherwise.
15 All ratios are weight ratios unless specifically stated otherwise.
Herein, "comprising" means that other steps and other ingredients which do not affect the end result can be added. This term encompasses the terms "consisting of and "consisting essentially of'.
Herein, "safe and effective amount" means an amount of active high 2o enough to provide a significant positive modification of the condition to be treated, but low enough to avoid serious side effects (at a reasonable benefit/risk ratio), within the scope of sound medical judgment. A safe and effective amount of active will vary with the particular condition being treated, the age and physical condition of the subject being treated, the severity of the condition the duration of 25 the treatment, the nature of concurrent therapy and like factors.
Non-limiting symptoms associated with cold and influenza-like illnesses include nasal congestion, sneezing, sinus pain, sore throat, runny nose, cough, chest pain and headaches. In addition, congestion is associated with certain respiratory afflictions. These respiratory afflictions include viral, bacterial, and fungal infections which may lead to sinusitis, otitis media, and pneumonia.
Other respiratory afflictions that result in congestion include inflammatory and immunological responses to allergens and pollutants.
s Nasal congestion is one manifestation of congestion generally.
Congestion is characterized by localized edema at tissues or organs that are inflamed or injured in response to colds and respiratory ailments. To this end, congestion is accompanied by increased fluid production at mucus producing tissues such as the nose, lungs, and throat. The increased fluid production is responsible for reducing airflow through a lumenal site such as nasal passages or even the lungs. Other locations that become congested include the head or facial sinuses, ear canals, and the throat. Sinus and otic openings (ostia) are usually kept open by normal cellular processing of mucus, foreign particles and bacterial imbalances. However, these locations and openings can become clogged due to excessive edema which results in sinus, middle ear or head pain.
The pain is believed to result from the increased pressure in the sinuses following a fluid influx that is coincident with an inflammatory cell influx which results, in part, to make more mucus or frank pus. Therefore, it is generally accepted that nasal congestion is associated and may be coincident with these conditions.
2o Nasal congestion results in the sensation of one's nose and nasal passages being blocked with the inability to conduct airflow through the nares.
One method of measuring such blockage is by measuring a subject's nasal airway resistance (NAR). NAR is a physical measure of resistance to air flow, calculated from pressure gradients, through the nasal passage (e.g.
naves, 25 turbinates) under normal breathing patterns. Congestion in nasal tissues increases NAR. Increases in NAR coincide with the sensation of blocked and/or clogged airways. The biological mechanisms in nasal congestion are relevant to both symptoms associated with cold and influenza-like illnesses and congestion associated with respiratory afflictions.
3o NAR is measured by acoustic and passive rhinometry. Amis, T.C., Oral airwa~r, flow dynamics in healthy humans, 515 J. Physiol. Lond. 293-8, 1999;
