<div><div>Vědci z Ústavu organické chemie a biochemie AV ČR (ÚOCHB) vyvinuli průlomovou technologii pro efektivní vývoj aptamerů. Nová metoda propojuje několik biochemických a bioinformatických kroků a otevírá cestu k novým diagnostickým a terapeutickým aplikacím. Mezi ně patří například nositelné senzory schopné v reálném čase sledovat hladiny vybraných biomarkerů v těle a včas upozornit na blížící se zdravotní komplikace. Výsledky zveřejnil časopis Nature Communications.</div></div><div>Aptamery jsou krátké řetězce DNA nebo RNA, které dokážou velmi přesně rozeznat a navázat konkrétní cílovou molekulu. Podobně jako protilátky je lze využít k detekci nebo ovlivnění funkce těchto molekul. Na rozdíl od protilátek jsou však mnohem stabilnější, lze je vyrábět synteticky a přesně chemicky upravovat podle požadovaných vlastností. Díky tomu mohou získat vlastnosti, kterých nelze u protilátek dosáhnout.<img src="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/UOCHB_Nova_technologie_inovuje_vyvoj_aptameru_syntetickych_alternativ_protilatek_2_81e99b9900.jpg" alt="ÚOCHB: Nová technologie inovuje vývoj aptamerů, syntetických alternativ protilátek: Chemicky upravený DNA aptamer navázaný na cílový protein." srcset="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/thumbnail_UOCHB_Nova_technologie_inovuje_vyvoj_aptameru_syntetickych_alternativ_protilatek_2_81e99b9900.jpg 228w," sizes="100vw" width="1343" height="916">S rostoucí poptávkou po přesných a rychlých diagnostických nástrojích jsou aptamery v mnoha případech vhodnější než samotné protilátky. Jejich vývojový proces je však experimentálně a časově náročný a vyžaduje experty z několika vědních oborů. Tým vědců z ÚOCHB vedený dr. Markem Ondrušem a <a target="_blank" rel="noopener noreferrer" href="https://hocek.group.uochb.cz/">prof. Michalem Hockem</a> nyní vyvinul technologii, která celý vývojový proces výrazně zkracuje.„Vývoj aptameru často připomíná hledání jehly v kupce sena. Ve směsi bilionů různých DNA sekvencí se snažíme najít jedinou, která se silně a specificky váže na cílovou molekulu. Náš nový přístup umožňuje nejdřív nalézt ‚aptamerové rodiny‘ – stovky sekvencí s jistou podobností a následně identifikovat člena rodiny, který vykazuje nejlepší experimentální vlastnosti. Tento prvek přispívá ke zkrácení vývoje z několika měsíců na dny,“ říká Marek Ondruš.<blockquote>Video: <a target="_blank" rel="noopener noreferrer" href="https://www.youtube.com/watch?v=-aoGvOKqORo">Nová technologie inovuje vývoj aptamerů, syntetických alternativ protilátek&nbsp;</a></blockquote>Výzkumníci zároveň rozšířili možnosti využití aptamerů. Jejich stavební bloky totiž chemicky upravují – připojují k nim nové funkční skupiny, které můžeme přirozeně najít například v aminokyselinách. Takto vzniklé molekuly kombinují výhody DNA i protilátek: pořadí jednotlivých stavebních bloků je dané pořadím písmen v DNA a díky rozmanitosti připojených chemických modifikací se výrazně rozšiřují možnosti aptameru rozpoznávat biologicky významné cíle a napodobovat interakce typické pro proteiny, které jsou základem mnoha biologických procesů.&nbsp;Potenciál nové metody ukázali vědci na lidském inzulinovém receptoru, klíčovém proteinu zapojeném do regulace hladiny cukru v krvi. Vyvinuli aptamer, který se na receptor specificky váže, a pomocí kryoelektronové mikroskopie detailně popsali molekulární mechanismus vzájemné vazby.„Ukázali jsme, že chemicky zavedené funkční skupiny mají zásadní význam nejen pro rozpoznání a vytvoření komplexu aptameru s proteinem, ale také pro stabilizaci samotné struktury DNA aptameru. Naše výsledky poskytují nový pohled na to, jak lze pomocí chemicky upravených nukleových kyselin napodobovat vlastnosti proteinů,“ shrnuje Marek Ondruš.Technologie by v budoucnu mohla doplnit nebo v některých aplikacích dokonce nahradit diagnostické nástroje založené na protilátkách.

V této práci představujeme strategii selekce v jediném kole, která umožňuje rychlý screening několika nadreprezentovaných DNA knihoven s modifikovanými nukleobázemi a různých selekčních podmínek a dokáže identifikovat modifikované aptamery s vysokou afinitou. Dvojitá separace následovaná amplifikací eluovaných sekvencí, analýzou NGS a klastrováním umožňuje rychlou identifikaci kandidátních aptamerů. Screening modifikovaných DNA knihoven obsahujících modifikované adeninové a uracilové nukleotidy nesoucí hydrofobní aromatické fenylové a indolové skupiny vedl k vývoji aptameru, který se váže na lidský inzulinový receptor se subnanomolární afinitou a mimořádnou specificitou. Struktura stanovená kryoelektronovou mikroskopií odhaluje význam každé aromatické modifikace, a to buď při stabilizaci sekundární struktury, nebo při zprostředkování interakcí s povrchem proteinu. Tento přístup překonává hlavní omezení selekce aptamerů a má potenciál pro vysokokapacitní screening i urychlení vývoje aptamerů nové generace pro diagnostické nebo terapeutické aplikace.</div>

Exploring Dissolution Techniques for Vaccines, Liposomes, and Parenterals

Let’s take a closer look at all these questions and try to answer them with our group of experts from the DDG panel and industry experts.

Dissolution for Vaccines, Liposomes, and Parenterals

While solid dosage forms like tablets are still the widely used option for the delivery of medication, there is an increasing need for alternative dosage forms. Medical devices are on the rise and when combined with a drug, they most likely also need to undergo dissolution testing, which can be challenging with the conventional apparatus. Many novel dosage forms, e.g. electro spun fleeces, microneedle patches, implants also require modifications to the dissolution apparatus we know. Join us for a discussions on these challenges and how they can be overcome.

Agilent Technologies: Current Practices for the Dissolution Testing of Medical Devices, Combination Products, and Novel Dosage Forms

Current Practices for the Dissolution Testing of Medical Devices, Combination Products, and Novel Dosage Forms

Join us for a discussions on challenges and how they can be overcome.

Practices for the Dissolution Testing of Medical Devices

Development of veterinary products is a challenge in itself. Animal ranges from very small to very large, so how to accommodate the large dosage range? Special flavors need to be added. What dosage forms are accepted by animals? Thinking about this, you can imagine, that dissolution testing of these products can present a real challenge. Let’s take a trip to the vet and explore our options.

Agilent Technologies: A Trip to the Vet: Expert Advice about Dissolution Testing of Veterinary Products

A Trip to the Vet: Expert Advice about Dissolution Testing of Veterinary Products

Let’s take a trip to the vet and explore our options.

Advice about Dissolution Testing of Veterinary Products

Novel dosage forms require novel dissolution techniques and instruments. Drug-eluting stent testing, transdermals, implants, contact lenses, medical devices, and a variety of other products require absolute control over evaporative losses and assurance of analytical sample integrity. The dissolution testing is frequently done using ultralow volumes in the 5–10 mL range.
In this webinar, we will explore tools and techniques that address the challenges of these types of analysis by examining several examples and case studies.
<h5>Key learning objectives</h5>
<ul>
<li>Discover dissolution techniques for novel formulations</li>
<li>Explore case studies for small-volume dissolution testing</li>
<li>Learn about the Agilent 400-DS</li>
</ul>
<h5>Who should attend?</h5>
<ul>
<li>Dissolution users, lab managers in R&amp;D and QC, and drug/device manufacturers</li>
</ul>
