Definitions
- the present invention relates to the use of the triglycoside solasonine (22R, 25R)- spiro-5-en-3 ⁇ -yl- ⁇ -L-rhamnopyranosyl-(1 ⁇ 2gal)-0-p-D-glucopyranosyl-(1->3gal)- ⁇ - D-galactopyranose for the preparation of pharmaceutical compositions for treating skin tumors.
- compositions according to the invention are useful for the treatment of human skin tumors, like premalignant skin lesions, malignant skin lesions.
- malignant skin tumors like basal cell carcinomas (BCCs), squamous cell carcinomas (SCCs), Karposi's sarcoma and benign skin tumors like actinic keratosis, keratoses and keratoacanthomas.
- BCCs basal cell carcinomas
- SCCs squamous cell carcinomas
- Karposi's sarcoma and benign skin tumors like actinic keratosis, keratoses and keratoacanthomas.
- BEC is incorporated in small concentrations into an over the counter (OTC) topical formulation (Curaderm®), which is used to treat skin lesions such as sunspots and keratosis.
- OTC over the counter topical formulation
- the present invention is directed to the use of the solasodine triglycoside solasonine for the preparation of pharmaceutical compositions for treating skin tumors.
- BEC Complex Extract of S. sodomaeum
- solasonine a crude mixture of solamargine (33%), solasonine (33 %) and of an undefined fraction of di-and monoglycosides (34 %), but the individual purified S. sodomaeum glycoside solasonine (formula 1 )
- BCCs basal cell carcinomas
- SCCs squamous cell carcinomas
- Karposi's sarcoma benign tumors.like actinic keratosis, keratoses and keratoacanthomas even in the absence of the other solasodine glycoside components. Since it is well recognized in the art that the effect of plant extract is very often caused by the often complex interactions and potentating effects of the individual compounds present in crude plant extracts comprising more than 1 potentially active component this finding was very unexpected.
- the invention provides a novel, more stable, fully characterized, effective pharmaceutical composition for treating skin tumors, benign as well as malignant tumors.
- compositions of the invention may be administered e. g. orally, parenterally, topically or via an implanted reservoir or therapeutic system, whereby parenteral or topical administration are preferred. Particularly preferred is the topical administration.
- Sterile injectable compositions according to the invention may be aqueous or oleagious formulation.
- formulations may be formulated according to techniques well known in the art using suitable solvents, diluents or vehicles such as water for injection, Ringer's solution and isotonic sodium chloride solution.
- suitable solvents such as water for injection, Ringer's solution and isotonic sodium chloride solution.
- adjuvants may also be used.
- the pharmaceutical compositon of the invention may also be orally administered in any orally acceptable dosage form, including capsules, tablets, granules, suspensions or solutions, which are also formulated according techniques well known in the art.
- the formulation may be in suitable formulations such as cremes, gels, ointments, liniments, lotions, emulsions and patches using suitable carriers and adjuvants well known in the art.
- the amount of incorporated solasonine in the composition will vary depending on the particular mode of administration as well as the nature of the condition to be treated, as well as the age, weight and condition of the patient.
- compositions especially the compositions for topical administration should be formulated to comprise between 0.001 and 10% (w/w), 0.001 and 4% (w/w)) preferably between 0.001 and 1% (w/w) and most preferably between 0.001% and 0.5% (w/w) of the formulation.
- a specific dosage and treatment regimen will depended upon variety of factors such as e. g. age, bodyweight, general state of health, sex of the patient, severity of disease and concommitant medication.
