Domanda di Brevetto per Invenzione Industriale dal titolo: "Impiego dell'acido guanidinacetico per indurre un incremento del contenuto muscolare di creatina" Patent Application for Industrial Invention entitled: "Use of guanidinacetic acid to induce an increase in muscle creatine content"

RIASSUNTO SUMMARY

L'acido guanidinacetico, o un suo sale, da solo o in associazione con metionina o con solfoadenosilmetionina viene utilmente impiegato nelle affezioni e nelle condizioni fisiche che richiedono un incremento del contenuto intracellulare muscolare di creatina. Guanidinacetic acid, or one of its salt, alone or in association with methionine or with sulfoadenosylmethionine is usefully used in diseases and physical conditions that require an increase in the intracellular muscle content of creatine.

Tecnica nota Known technique

E' noto che nel tessuto muscolare esistono diversi composti biologici a contenuto energetico di cui il principale ? l'adenosina trifosfato (ATP). It is known that in muscle tissue there are several biological compounds with energy content, the main one of which? adenosine triphosphate (ATP).

Tra queste sostanze riveste una grande importanza la creatina fosfato la quale ? in rapporto con l'ATP nel senso che tra i due composti ha luogo uno scambio di gruppi fosfato. Among these substances, creatine phosphate is of great importance, which? in relation to ATP in the sense that an exchange of phosphate groups takes place between the two compounds.

L'importanza della creatina ? dimostrata dal fatto che in condizioni di ischemia del miocardio si ha 1' arresto della funzione contrattile del cuore al momento dell'esaurimento della creatina stessa mentre ? presente ancora il 90% dell'ATP. The importance of creatine? demonstrated by the fact that in conditions of myocardial ischemia there is the arrest of the contractile function of the heart at the time of exhaustion of the creatine itself while? 90% of ATP is still present.

Ci? ? dovuto al fatto che l'ATP disponibile per cedere immediatamente energia per la contrazione ? solamente una piccola parte dell?ATP presente il quale funziona da riserva. E' compito della creatina ricaricare l'ATP affinch? possa cedere energia per la contrazione. There? ? due to the fact that the ATP available to immediately release energy for the contraction? only a small part of the present ATP which functions as a reserve. It is the creatine's job to recharge the ATP so that? can release energy for contraction.

Da queste considerazioni emerge chiaramente un problema importante cio? il problema di aumentare,quando necessario, la creatina nel muscolo. Ci? consentirebbe una efficienza pi? prolungata e pi? potente del muscolo sia cardiaco che scheletrico. From these considerations, an important problem clearly emerges, that is? the problem of increasing creatine in the muscle when needed. There? would allow an efficiency more? prolonged and more? powerful of both cardiac and skeletal muscle.

Infatti, mentre la riserva di ATP ? facilmente rifornibile sia in aerobiosi che in anaerobiosi, la performance contrattile, specie in anaerobiosi, ? funzione della quantit? di creatina presente. Indeed, while the reserve of ATP? easily replenished both in aerobiosis and in anaerobiosis, the contractile performance, especially in anaerobiosis,? function of the quantity? of creatine present.

Perci? tale sostanza ? di grandissimo interesse sia in campo medico che sportivo: basta pensare ad esempio a quante vite si potrebbero salvare nell?infarto del miocardio se si riuscisse a fare continuare le contrazioni cardiache in condizioni di ischemia fino alla ripresa di una corretta ossigenazione del tessuto infartuato oppure nell'attivit? sportiva quanto potrebbe rendere un atleta in uno sport con sforzo di tipo esplosivo, come i 100 metri, laddove l'atleta compie la sua performance in apnea. So? such substance? of great interest both in the medical and sports fields: just think, for example, of how many lives could be saved in myocardial infarction if it were possible to make cardiac contractions continue in conditions of ischemia until the resumption of proper oxygenation of the infarcted tissue or in activity as sporty as an athlete could make in a sport with an explosive type of effort, such as 100 meters, where the athlete performs his performance in apnea.

D'altra parte si deve tenere presente che la creatina viene sintetizzata principalmente nel rene e nel fegato per cui si avr? una carenza nel corso di tutte le nefropatie ed epatopatie con compromissione parenchimale. On the other hand, it must be borne in mind that creatine is synthesized mainly in the kidney and liver for which it will have? a deficiency in all renal and hepatopathies with parenchymal compromise.

Purtroppo la somministrazione di creatina esogena non porta ad alcun risultato positivo in quanto la creatina esogena inibisce la sintesi di creatina endogena per una quantit? pari alla quantit? di creatina somministrata. Unfortunately, the administration of exogenous creatine does not lead to any positive result as exogenous creatine inhibits the synthesis of endogenous creatine for a quantity? equal to the quantity? of creatine administered.

Sommario Summary

Ora noi abbiamo trovato che i problemi della tecnica anteriore possono essere superati mediante la somministrazione di acido guanidinacetico, o di un suo sale, da solo o in associazione con metionina o con solfoadenosil-metionina. We have now found that the problems of the prior art can be overcome by administering guanidinacetic acid, or one of its salt, alone or in combination with methionine or sulfoadenosyl-methionine.

Detta somministrazione porta ad un incremento del contenuto intracellulare muscolare di creatina e quindi aumenta la disponibilit? di energia per le cellule muscolari sia scheletriche che cardiache. This administration leads to an increase in the intracellular muscle content of creatine and therefore increases the availability? of energy for both skeletal and cardiac muscle cells.

Descrizione dettagliata dell'invenzione Detailed description of the invention

Gli effetti ed i vantaggi della somministrazione di acido guanidinacetico (AGA) da solo o in associazione con metionina o solfoadenosil-metionina (SAME) allo scopo di incrementare il contenuto intracellulare muscolare di creatina saranno maggiormente illustrati nel corso della seguente descrizione dettagliata. The effects and advantages of administering guanidinacetic acid (AGA) alone or in combination with methionine or sulfoadenosyl-methionine (SAME) in order to increase the intracellular muscle content of creatine will be further illustrated in the course of the following detailed description.

In una sperimentazione condotta sui ratti ? stato somministrato AGA come supplementazione ad una dieta standard. Per la determinazione dell'aumento del contenuto intracellulare muscolare della creatina sono state raccolte le urine escrete nelle 24 ore ed ? stata dosata la concentrazione di creatinina. Questo dosaggio ? una misura del tutto affidabile del contenuto intracellulare della creatina in quanto, come noto, l'eliminazione renale della creatinina ? funzione matematica della concentrazione intracellulare di creatina e non dipende da alcun altro parametro come ad esempio l'esercizio muscolare o l?introduzione calorica. In a rat experiment? AGA was given as a supplement to a standard diet. Urine excreted within 24 hours and? the creatinine concentration was measured. This dosage? a completely reliable measure of the intracellular content of creatine since, as is known, the renal elimination of creatinine? mathematical function of the intracellular concentration of creatine and does not depend on any other parameter such as muscle exercise or caloric intake.

La sperimentazione con AGA ? stata realizzata in due stadi della durata di una settimana ciascuno, intervallati da un periodo di tre giorni tra il primo stadio ed il secondo stadio. Nella settimana precedente la sperimentazione con AGA veniva monitorizzata la creatininuria nei ratti alimentati con una dieta che conteneva metionina in quantit? pari al fabbisogno del ratto, pi? una quantit? di metionina pari a 1,7 mg/kg di peso corporeo, quantit? pari a quella necessaria per attivare l'AGA che sar? aggiunto nelle settimane successive. Experimentation with AGA? it was carried out in two stages lasting one week each, interspersed with a period of three days between the first stage and the second stage. In the week preceding the AGA experiment, creatininuria was monitored in rats fed a diet that contained methionine in quantities. equal to the needs of the rat, more? a quantity? of methionine equal to 1.7 mg / kg of body weight, quantity? equal to that necessary to activate the AGA which will be? added in the following weeks.

Nel 1? stadio della sperimentazione con AGA i ratti vennero alimentati con la dieta della settimana precedente supplementata con AGA in quantit? di 1,7 mg/Kg di peso corporeo. In the 1? stage of the experiment with AGA the rats were fed the previous week's diet supplemented with AGA in quantity. of 1.7 mg / kg of body weight.

Dopo una settimana ? stata sospesa per 3 giorni la supplementazione della dieta con AGA. After a week? Dietary supplementation with AGA was suspended for 3 days.

Dopo questa sospensione i ratti sono stati alimentati con dieta supplementata con AGA ancora per una settimana (2? stadio). After this suspension, the rats were fed an AGA supplemented diet for another week (2nd stage).

I risultati ottenuti sono riportati nella tabella 1. The results obtained are shown in table 1.

C'? da osservare che nel procedimento di sintesi della creatina a partire da AGA c?? il pericolo di sottrarre metionina ad altri procedimenti metabolici. Per questo motivo la presente invenzione prevede anche di associare la metionina o la SAME all'AGA con un rapporto molare fra metionina o SAME ed AGA compreso fra 0,5:1 e 3:1? There? it should be noted that in the creatine synthesis process starting from AGA c ?? the danger of removing methionine from other metabolic processes. For this reason, the present invention also envisages associating methionine or SAME with AGA with a molar ratio between methionine or SAME and AGA between 0.5: 1 and 3: 1?

La somministrazione dell'AGA e dell'associazione AGA-metionina o AGA-SAME trova quindi una importantissima indicazione in tutte quelle condizioni in cui ? necessario o opportuno aumentare la concentrazione intramuscolare di creatina, e particolarmente nelle nefropatie ed epatopatie con compromissione parenchinale, nelle persone anziane, nelle condizioni di iponutrizione e nella ischemia cronica e acuta del muscolo miocardico. The administration of AGA and the AGA-methionine or AGA-SAME association therefore finds a very important indication in all those conditions in which? It is necessary or appropriate to increase the intramuscular concentration of creatine, and particularly in renal and hepatopathies with parenchinal compromise, in the elderly, in conditions of hyponutrition and in chronic and acute ischemia of the myocardial muscle.

Dette sostanze sono inoltre utilmente somministrabili ad atleti che praticano sport che richiedono sforzi di tipo esplosivo. La somministrazione dell'AGA e dell'associazione AGA-metionina o AGA-SAME pu? essere effettuata per via orale o per via parenterale Impiegando dette sostanze allo stato puro oppure sotto forma di composizioni comprendenti diluenti ed eccipienti farmacologicamente accettabili. Said substances can also be usefully administered to athletes who practice sports that require explosive efforts. The administration of the AGA and the association AGA-methionine or AGA-SAME can? be carried out orally or parenterally using said substances in their pure state or in the form of compositions comprising pharmacologically acceptable diluents and excipients.

L'AQA pu? essere impiegato tal quale oppure sotto forma di sale con un catione farmacologicamente accettabile. The AQA can be used as such or in the form of a salt with a pharmacologically acceptable cation.

La quantit? giornaliera di AGA da somministrare ? compresa nel campo da 0,0001 a 5 mg/Kg di peso corporeo in pi? somministrazioni giornaliere. The quantity daily of AGA to be administered? included in the range from 0.0001 to 5 mg / kg of body weight in pi? daily administrations.
