Characterization testing is utilized to gain an understanding of the physical and chemical properties of biopharmaceutical materials.

To ensure product safety and efficacy, protein therapeutics must meet defined quality characteristics immediately after manufacture as well at the end of their designated shelf lives. Many physical and chemical factors can affect the quality and stability of biopharmaceutical products, particularly after long-term storage in a container—closure system likely to be subject to variations in temperature, light, and agitation with shipping and handling. Compared with traditional chemical pharmaceuticals, proteins are considerably larger molecular entities with inherent physiochemical complexities, from their primary amino acid sequences through higher-order secondary and tertiary structures — and in some cases, quaternary elements such as subunit associations 1. Many proteins are glycosylated, and some have other posttranslational modifications such as phosphorylation, which also affects their potential degradation pathways as well as the kinetics of their degradation. Proteins are typically sensitive to slight changes in solution chemistry.

Crystallization is the bottleneck in macromolecular crystallography; even when a protein crystallises, crystal packing often influences ligand-binding and protein—protein interaction interfaces, which are the key points of interest for functional and drug discovery studies. The human hypoxia-inducible factor prolyl hydroxylase 2 PHD2 readily crystallises as a homotrimer, but with a sterically blocked active site. We explored strategies aimed at altering PHD2 crystal packing by protein modification and molecules that bind at its active site and elsewhere.

The information in THPdb has been compiled from research publications, 70 patents and other resources like DrugBank. The current version of the database holds a total of entries, providing comprehensive information on US-FDA approved therapeutic peptides and proteins and their drug variants. The information on each peptide and protein includes their sequences, chemical properties, composition, disease area, mode of activity, physical appearance, category or pharmacological class, pharmacodynamics, route of administration, toxicity, target of activity, etc. In addition, we have annotated the structure of most of the protein and peptides. A number of user-friendly tools have been integrated to facilitate easy browsing and data analysis.

Stability and Characterization of Protein and Peptide Drugs

The success of most peptide and protein drugs is dependent upon the delivery of the biologically active form to the site of action. In the design and development of formulations to achieve this goal, the formulation scientist must consider the clinical indication, pharmacokinetics, toxicity, and physicochemical stability of the drug. The development of a stable formulation is a necessary step for each new protein or peptide therapeutic. The degradation pathways and their impact on stability should be systematically analyzed and competing degradation rates must be balanced to arrive at the most stable formulation possible. Several routes of administration should also be considered and future development of new formulations may expand the number of potential options.

Sleat, Vikas Nanda, Peter Lobel; Lysosomal protein thermal stability does not correlate with cellular half-life: global observations and a case study of tripeptidyl-peptidase 1. Biochem J 14 February ; 3 : — Late-infantile neuronal ceroid lipofuscinosis LINCL is a neurodegenerative lysosomal storage disorder caused by mutations in the gene encoding the protease tripeptidyl-peptidase 1 TPP1. In this study, we utilized protein engineering techniques to increase the stability of recombinant TPP1 with the rationale that this may lengthen its lysosomal half-life, potentially increasing the potency of the therapeutic protein.

Use of cyclic peptides to induce crystallization: case study with prolyl hydroxylase domain 2

Drug design , often referred to as rational drug design or simply rational design , is the inventive process of finding new medications based on the knowledge of a biological target. In the most basic sense, drug design involves the design of molecules that are complementary in shape and charge to the biomolecular target with which they interact and therefore will bind to it. Drug design frequently but not necessarily relies on computer modeling techniques. Finally, drug design that relies on the knowledge of the three-dimensional structure of the biomolecular target is known as structure-based drug design. The phrase "drug design" is to some extent a misnomer.

 Какого черта, - промычал он себе под нос.

Formulation, Characterization, and Stability of Protein Drugs

Мысли ее смешались. Хоть бы замолчала эта омерзительная сирена. Почему Стратмор отмел такую возможность.

Джабба нажал на клавишу. И в следующую секунду все присутствующие поняли, что это было ошибкой. ГЛАВА 119 - Червь набирает скорость! - крикнула Соши, склонившаяся у монитора в задней части комнаты.  - Неверный ключ. Все застыли в ужасе. На экране перед ними высветилось сообщение об ошибке: НЕДОПУСТИМЫЙ ВВОД.

 Это рекламный ход. Не стоит волноваться. Копия, которую он разместил, зашифрована. Ее можно скачать, но нельзя открыть. Очень хитро придумано. Ключ к Цифровой крепости зашифрован и недоступен.

Covering the whole development process for the global biotechnology industry

Он считал себя большим знатоком всего, что способствовало укреплению здоровья, и утверждал, что оливковое масло очищает кишечник. Он вечно навязывал что-то коллегам, например морковный сок, и убеждал их, что нет ничего важнее безукоризненного состояния кишечника. Хейл поставил масло на место и направился к своему компьютеру, располагавшемуся прямо напротив рабочего места Сьюзан. Даже за широким кольцом терминалов она почувствовала резкий запах одеколона и поморщилась. - Замечательный одеколон, Грег.

 Выходит, все в порядке. - Это лишь означает, - сказала она, пожимая плечами, - что сегодня мы не взломали ни одного шифра. ТРАНСТЕКСТ устроил себе перерыв. - Перерыв? - Бринкерхофф не был в этом уверен. Он достаточно долго проработал бок о бок с директором и знал, что перерыв не относился к числу поощряемых им действий - особенно когда дело касалось ТРАНСТЕКСТА.

Но уже через минуту парень скривился в гримасе. Он с силой стукнул бутылкой по столу и вцепился в рубашку Беккера. - Она девушка Эдуардо, болван.

 Шестьдесят четыре буквы. Юлий Цезарь всегда с нами. Мидж развела руками.

Внезапно Стратмор сбросил оцепенение. - Иди за мной! - сказал. И направился в сторону люка. - Коммандер. Хейл очень опасен.

Включился звук, и послышался фоновой шум. - Установлена аудиосвязь. Через пять секунд она станет двусторонней.
