Bağlı anyonik polimerizasyon molekül ağırlığı üzerinde sağladığı iyi kontrol etmek için, oksiran monomerler (PEG ve PEG) göre polimerlerin hazırlanması için sanayide en çok kullanılan süreçlerden biridir. Başarılı bir polimerizasyon elde edilmesi için en uygun ve sıkı koşullar kullanılmalıdır. Tüm reaktifler ve uygun düzeneğin titiz saflaştırma sentezi oturma karakteri için önemlidir. Geçerli kurulum Sınırlamalar çoğunlukla kanülasyon dayanır transfer tekniği ile ilişkilid...

sulu ortam içinde, amfifilik blok kopolimerleri bir hidrofilik kabuk veya korona ile çevrili bir hidrofobik çekirdeğin oluşur nano-boyutlu blok kopolimer miselleri (BCMS) oluşturmak için bir araya getirin. misel temel hidrofobik ilaçlar dahil edilmesi için bir rezervuar olarak hizmet edebilir; birlikte, hidrofilik korona iç ve dış ortam arasında bir arabirim sağlar. Poli (etilen glikol) (PEG) ve bunun türevleri, polimerler en önemli sınıflarından birini ve en çok ilaç formülasyonunda kullanılan bulunmaktadır. 1-3 BCMS birçok formülasyonları bu dayanarak bir değerli ilaç verme platformu olduğu kanıtlanmıştır Teknoloji artık geç aşama klinik geliştirme. 4. En sık olarak, kopolimerin hidrofobik blok polikaprolakton, poli (D, L-laktid), poli (propilen oksit) veya poli (β-benzil-L-aspartat) oluşur. 5 -9 Kataoka grubu in- b oluşan küresel misellerin incelenmiştir </em&gt; -PBLA Ve poli (etilen oksit) -. B - raporlarında doksorubisin doğum (DOX) 10,11 için (poliaspartik asit-konjuge doksorubisin), bu polimer konjuge ilaç veya PBLA arasındaki π-π etkileşimler olduğunu ortaya koydu ve ücretsiz DOX ilaç yüklemesi ve saklama artışlar sonucunda misel çekirdeği stabilize etmek için hareket ederler. Bir ilaç ve çekirdek oluşturan blok arasındaki uyumluluk veya etkileşimleri kurulmuş olan anahtar performans ile ilgili parametrelerin belirleyicileri. DOX ek olarak 12, kanser tedavi bir dizi kendi çekirdek yapısı (örneğin, metotreksat, olaparib, SN içinde aromatik halkalar içeren -38). Sonuç olarak çekirdek oluşturucu blok benzil halkaları içerir kopolimerlerin sentezi önemli bir ilgi vardır. PEG ve türevlerinin Anyonik halka-açma polimerizasyon molekül ağırlığı üzerinde kontrol sağlayan ve iyi bir verimle düşük poli dispersiteye sahip malzeme ile sonuçlanır. 13,14 etilenfenil glisidil eter (PheGE) veya stiren oksit ile NE oksit (SO) hidrofobik ilaçlar çözünürleştirme için miseller oluşturan blok kopolimerler oluşturmak için polimerize (ko) olabilir. 15-18 mevcut rapor fenil anyonik polimerizasyonunu yaşam için gerekli adımları açıklamaktadır makrobaşlatıcı olarak mPEG-OH üzerinde eter monomer glisidil (Şekil 1). Elde edilen blok kopolimer ve agrega daha sonra ilaç iletiminde kullanım açısından özellikleri açısından karakterize edilir.

anionic polymerization of an amphiphilic copolymer for preparation of block copolymer micelles stabilized by &#960;-&#960; stacking interactions

Bu çalışmada, fenil grubu ile bir çekirdek-oluşturucu blok içeren bir amfifilik kopolimerin metoksi-polietilen glikol (MPEG-B -PPheGE) hakkında fenil glisidil eter (PheGE) anyonik polimerizasyonunu canlı sentezlendi. Kopolimerin karakterizasyonu dar bir molekül dağılımı (PDI &lt;1.03) ortaya çıktı ve mPEG 122 polimerizasyon derecesi teyit - B - (PheGE) 15. kopolimerin kritik misel konsantrasyonu, dinamik ışık saçılımı ve iletim elektronik mikroskopi ile değerlendirildi çekiş davranışı ile oluşturulmuş bir floresans yöntemi kullanılarak değerlendirildi. İlaç verme uygulamalarında kullanım için kopolimerin potansiyeli, in vitro biyolojik uyumluluk, yükleme ve hidrofobik bir anti-kanser ilaç doksorubisin (DOX) serbest bırakılması da dahil olmak üzere bir ön şekilde değerlendirilmiştir. DOX stabil bir misel formülasyonu% 14 (ağırlık olarak%), effici ilaç yüklemesi kadar ilaç yükleme seviyeleri elde edilmiştirasetatlara&gt;% 60 fizyolojik olarak ilgili koşullar (asidik ve nötral pH albümin varlığı) altında 4 gün boyunca ilacın özelliğine ve sürekli bırakmaya (a / a). Yüksek ilaç yükü seviyesi ve sürekli salınan DOX ve misellerin çekirdek oluşturucu blok arasında π-π etkileşimleri stabilize ilişkilendirilir.
