Description

TARIFNAME MAL VA SYL VESTRIS L. ÇIÇEKLERININ STANDARDIZE EKSTRELERININ COX-l, COX-Z VE LOX ENZIMLERINI INHIBE EDICI ETKILERI Teknik Alan Mevcut bulus, antienflamatuvar ajan olarak kullanim için Malva sylvestris L. çiçeklerinin malvin üzerinden standardize ekstresi ile ilgilidir. Teknigin Bilinen Durumu Enilamasyon kaynakli rahatsizliklar siklikla karsimiza çikmaktadir. Vücudun farkli bölgelerinde farkli nedenlerle meydana gelen enflamasyonlarin tedavisi çesitli konvansiyonel ilaçlarla saglanmaya çalisilmaktadir. Ancak kullanilan bu ajanlarla tedavi zaman zaman yetersiz kalmakla beraber yeni ve dogal antienflamatuar aj anlarin kesfi büyük Önem tasimaktadir. Dogal kaynakli terapötik ajanlarin ticari kullaniminda en çok karsilasilan problemlerden biri dogal ürünlerden elde edilen ekstrelerin içerisindeki farmasötik etkiye sahip madde miktarinin sabit olmamasidir. Bitkinin toplandigi bölgeye veya toplandigi döneme göre degisiklik gösterebilen burn iktar degisikligi, bitkisel kökenli ekstreler kullanilarak etkinligi tekrar edilebilir ve standardize edilebilir formülasyonlar gelistirilmesini engellemektedir. Teknigin bilinen durumu göz önüne alindiginda hem bitkisel veya dogal kaynaklardan elde edilen hem de içerisinde bulunan farmasötik etkinlik gösteren madde miktari yönünden standardize edilebilen, farma kalitede antienflamatuar ajanlara ihtiyaç oldugu görülmektedir. Bulusun Amaci Bulus sahipleri, bitkisel veya dogal kaynaklardan elde edilen ve içerisinde bulunan farmasötik etkinlik gösteren madde miktari yönünden standardize edilebilen antienilamatuar ajanlar gelistirmeyi amaçlamaktadir.

Bulus kapsaminda bahsedilen % malvin miktari, standardize ekstrenin Türk Farmakopesi-ll monogratlar (Avrupa farmakopesi adaptasyonu) - 2016 isimli kaynakta (TC. Saglik Bakanligi, Türkiye Ilaç ve Tibbi Cihaz kurumu, 1. Baski, 2016) Malva sylvestri's çiçeklerininekstresinde malvin tayininde kullanilan herhangi bir analiz yöntemi örnegin HPLC ve/veya HPTLC cihazi analizleri ile belirlenmektedir. Burada kullanilan antienflamatuar ajan ifadesi, COX-l ve/veya COX-Z ve/veya LOX inhibitörü etkisi gösteren aj anlari da kapsamaktadir. Bu bulus kapsaminda bahsi geçen % orani relatif bir oran olup, analize tabi tutulan Malva sylvestri's çiçeklerinin ekstresi numunesindeki toplam madde miktarina kiyasla malvin miktarini ifade etmektedir. Örnegin, bir Malva sylvestri's çiçeklerinin ekstresi numunesinin HPLC analizinde elde edilen tüm pik alani 100 ile ifade edilecek olursa, bulusa uygun bir Malva sylvestri's çiçeklerinin ekstresi numunesinde malvin*e karsilik gelen pikin alani en az 0,1 olmalidir. Bulus bir diger açidan, antienflamatuvar ajan olarak kullanima uygun Malva sylvestri's çiçeklerinin en az % 0,1, tercihen %0,l-l araliginda malvin içeren standardize ekstresini içeren farmasötik bilesimlere iliskindir. Bulusun bir diger unsuru, etken madde olarak Malva sylvestris çiçeklerinin en az % 0,1, tercihen bu etken maddeye ilave olarak bir diger antienflamatuar ajan kullanilmasidir. Bulusun bir uygulamasinda bahsi geçen ilave antienflamatuar ajan ibuprofen veya diklofenak olabilir. Bulusa uygun kombinasyonlar, ayni dozaj formunda veya farkli dozaj formlarinda formüle edilebilir.

Oral formülasyonlar, tablet, kapsül, uzun salinimli kapsül, geciktirilmis salinimli kapsül, surup, emülsiyon, süspansiyon, kaplamali tablet, katmanli tablet, agizda dagilan tablet, efervesan tablet, sase, dil alti tablet formlarindan herhangi birinde olabilir. Topikal formülasyonlar, merhem, krem, jel, hidrojel, losyon formlarindan herhangi birinde olabilir. Bulusa uygun formülasyonlar içerisinde Malva sylvestris çiçeklerinin en az % 0,1 malVin içeren ekstresine ek olarak farmasötik olarak kabul edilebilir en az bir yardimci madde olabilir. Bahsi geçen yardimci madde, herhangi bir terapötik etkisi olmayip, fonnülasyonun hazirlanmasi veya korunmasi veya kullanimi esnasinda ortaya çikan bir gereksinimi karsilamak için kullanilabilir. Endüstriye Uygulanabilirlik Bulus sayesinde antienflamatuar ajan olarak kullanima uygun dogal kökenli ajanlar gelistirilmistir. Bu yönüyle bulus hem saglik sektöründeki son kullanicilari hem de ilaç gelistiricilerini il gilendirrnektedir. Örnekler Örnek 1: Bulusa uygun Malva sylvestri's çiçeklerinin ekstresinin COX-l ve COK-2 inhibisyonu için ICso degerleri ve bilinen antienflamatuar ajanlarla karsilastirilmasi Asagida sonuçlari verilen çalismada kullanilan Malva sylvestri's çiçeklerinin ekstresi içerisinde % 0,19 malvin bulunmaktadir. Madde No. ICso (ug/mL) SI Örnek lade yer alan sonuçlar degerlendirildiginde bulusa uygun Malva sylvesm's çiçeklerinin malvin üzerinden standardize ekstresinin dogal bir ekstre olmasina ragmen ticari olarak uzun sürelerdir kullanilan antientlamatuvar ajanlardan daha iyi veya anlamli derecede yakin antienflamatuar etki gösterdigi görülmektedir. Burada bahsi geçen antientlamatuar etki COX-l ve/veya COK-2 inhibisyonu üzerinden gösterilmektedir. Özellikle ilaç piyasasinda uzun yillardir siklikla kullanilan antienilamatuar ajanlardan olan ibuprofen ve diklofenak etken maddelerine kiyasla daha iyi COX-l ve COX-2 inhibisyonunun görülmesi bu dogal kaynakli standardize ekstrelerin önemli antieflamatuar ajanlar olabilecegini ortaya koymaktadir. Ayrica, bulusa uygun Malva sylvestris çiçeklerinin malvin üzerinden standardize ekstresinin COX- 2 üzerinde her iki bilinen ajandan daha etkin oldugu yukarida verilen tablodan görülmektedir, bu özelligi ile bulusa uygun bu ekstrenin bazi antienflamatuar ajanlarda siklikla görülen mide tahris edici etkiye sahip olmadigi da tespit edilmistir. Bu yönüyle de bulusa uygun standardize ekstreler bilinen teknikte var olan ajanlardan daha üstün etki göstermektedir. TR TR TR DESCRIPTION MAL VA SYL INHIBITORY EFFECTS OF STANDARDIZED EXTRACTS OF VESTRIS L. FLOWERS ON COX-1, COX-Z AND LOX ENZYMES Technical Field The present invention relates to the standardized extract of Malva sylvestris L. flowers on malvin for use as an anti-inflammatory agent. Known Status of the Technique Disorders caused by enlargement occur frequently. Inflammations that occur in different parts of the body for different reasons are tried to be treated with various conventional drugs. However, although treatment with these agents is sometimes insufficient, the discovery of new and natural anti-inflammatory agents is of great importance. One of the most encountered problems in the commercial use of naturally derived therapeutic agents is that the amount of substances with pharmaceutical effects in the extracts obtained from natural products is not constant. Variation in nose quantity, which may vary depending on the region where the plant is collected or the period in which it is collected, prevents the development of reproducible and standardizable formulations using plant-derived extracts. Considering the known state of the art, it appears that there is a need for pharmaceutical quality anti-inflammatory agents that are obtained from herbal or natural sources and can be standardized in terms of the amount of pharmaceutically active substances they contain. Purpose of the Invention The inventors aim to develop anti-inflammatory agents that are obtained from herbal or natural sources and can be standardized in terms of the amount of pharmaceutically active substances they contain. Brief Description of the Invention The present invention relates to the standardized extract of Malva sylvestris flowers based on malvin for use as an anti-inflammatory agent, or to compounds containing malvin in any ratio, for example 0% to 99%, preferably plant extracts containing 0% to 99% malvin, particularly preferably It is intended for the extract of Malva sylvestris flowers, which contains malvin in high amounts. Since malvin-standardized extracts were used in the invention, the results of the study are reproducible and questionable. Moreover, since there are not many agents that selectively inhibit COX and LOX enzymes, a natural anti-inflammatory agent is provided to patients with the standardized extract of Malva sylvestris flowers on malvin for use as an anti-inflammatory agent according to the invention. Detailed Description of the Invention The present invention is directed to the standardized extract of Malva sylvestris flowers via malvin for use as an anti-inflammatory agent. Another embodiment of the invention is directed to the standardized extract of Malva sylvestrz's flowers containing at least 0.1%, preferably 0.1-1% malvin, for use as an anti-inflammatory agent. The % malvin amount mentioned within the scope of the invention is determined by the standardized extract in the Turkish Pharmacopoeia-II monogrades (European pharmacopoeia adaptation) - 2016 (Turkish Ministry of Health, Turkish Medicines and Medical Devices Agency, 1st Edition, 2016) without any data used in the determination of malvin in the extract of Malva sylvestri's flowers. The analysis method is determined, for example, by HPLC and/or HPTLC device analysis. The term anti-inflammatory agent used herein also includes agents that have COX-1 and/or COX-Z and/or LOX inhibitory effects. The percentage mentioned within the scope of this invention is a relative ratio and expresses the amount of malvin compared to the total amount of substance in the extract sample of Malva sylvestri's flowers subjected to analysis. For example, if the entire peak area obtained in the HPLC analysis of a Malva sylvestri's flower extract sample is expressed as 100, the area of the peak corresponding to malvin in a Malva sylvestri's flower extract sample according to the invention must be at least 0.1. In another aspect, the invention relates to pharmaceutical compositions containing the standardized extract of Malva sylvestri's flowers, suitable for use as an anti-inflammatory agent, containing at least 0.1%, preferably 0.1-1% malvin. Another element of the invention is to use at least 0.1% of Malva sylvestris flowers as the active ingredient, preferably another anti-inflammatory agent in addition to this active ingredient. In one embodiment of the invention, said additional anti-inflammatory agent may be ibuprofen or diclofenac. The combinations according to the invention can be formulated in the same dosage form or in different dosage forms. If the combination formulations according to the invention are formulated in different dosage forms, said formulations can be used at different times or simultaneously or sequentially. The formulations according to the invention can be formulated in a dosage form suitable for oral or topical use. Oral formulations can be in any of the forms of tablets, capsules, extended-release capsules, delayed-release capsules, syrups, emulsions, suspensions, coated tablets, layered tablets, orodispersible tablets, effervescent tablets, sachets, and sublingual tablets. Topical formulations can be in any of the forms of ointment, cream, gel, hydrogel or lotion. Formulations according to the invention may contain at least one pharmaceutically acceptable excipient in addition to the extract of Malva sylvestris flowers containing at least 0.1% malVin. Said excipient does not have any therapeutic effect and can be used for the preparation or maintenance of the formulation or to meet a need arising during its use. Industrial Applicability Thanks to the invention, natural origin agents suitable for use as anti-inflammatory agents have been developed. In this respect, the invention interests both end users in the healthcare sector and drug developers. Examples Example 1: IC50 values of the extract of Malva sylvestri's flowers according to the invention for COX-1 and COK-2 inhibition and its comparison with known anti-inflammatory agents. The extract of Malva sylvestri's flowers used in the study whose results are given below contains 0.19% malvin. Item No. ICso (ug/mL) SI When the results in the sample are evaluated, it is seen that the standardized extract of Malva sylvesm's flowers on malvin according to the invention has a better or significantly closer anti-inflammatory effect than the anti-inflammatory agents that have been used commercially for a long time, even though it is a natural extract. The anti-inflammatory effect mentioned here is demonstrated through COX-1 and/or COK-2 inhibition. Particularly, the observation of better COX-1 and COX-2 inhibition compared to the active ingredients of ibuprofen and diclofenac, which are anti-inflammatory agents that have been frequently used in the pharmaceutical market for many years, reveals that these naturally derived standardized extracts may be important anti-inflammatory agents. In addition, it can be seen from the table above that the standardized extract of Malva sylvestris flowers based on the invention is more effective on COX-2 than both known agents. With this feature, it has been determined that this extract in accordance with the invention does not have the stomach irritating effect that is often seen in some anti-inflammatory agents. In this respect, the standardized extracts in accordance with the invention have a superior effect than the agents available in the known art. TR TR TR
