Define Quantitative structural activity relationship?
Quantitative structure-activity relationship (QSAR)(sometimes QSPR: quantitative structure-property relationship)QSAR is the process by which chemical structure is quantitatively correlated with a well defined process, such as biological activity or chemical reactivity.For example, biological activity can be expressed quantitatively as in the concentration of a substance required to give a certain biological response. Additionally, when physicochemical properties or structures are expressed by numbers, one can form a mathematical relationship, or quantitative structure-activity relationship, between the two. The mathematical expression can then be used to predict the biological response of other chemical structures.http://en.wikipedia.org/wiki/Quantitative_structure-activity_relationship

What is the relationship between aspirin and carboxylic acid?
Aspirin is a derivative of salicylic acid, which is a type of carboxylic acid. The carboxylic acid group in the structure of salicylic acid is essential for the formation of aspirin through acetylation. So, aspirin can be thought of as an acetylated form of salicylic acid that retains its carboxylic acid functionality.
What does QSP stand for?
QSP stands for Quantitative Structure-Activity Relationship. It is a computational method used in drug discovery to predict the biological activity of chemical compounds based on their structure and physicochemical properties.
Why is aspirin more reactive than benzene?
Benzene has a stable structure. Aspirin has an carboxylic group with delocalized electrons. So aspirin is more reactive than benzene.
What is the relationship between salicylic acid and aspirin?
Salicylic acid is a precursor to aspirin, which is a derivative of salicylic acid. When salicylic acid is acetylated, it becomes aspirin. Aspirin is a common medication used for pain relief and reducing inflammation.
Structure activity relationship of antiplatelet drugs?
More correctly it is called antiplatelet aggregation drugs (also called antithrombotic drugs) that include aspirin, clopidogrel, abciximab (monoclonal antibodies) and GPII/ IIIA receptors antagonists etc. Each drug has its own way and mechanism of action. It depends upon chemical structure of drug and site of action. Aspirin blocks aggregation by inhibiting cycloxygenase that produce thromboxane A2 that causes platelet aggregation. Clopidogrel acts as antagonist to P2Y2 receptors present on platelets required for their aggregation. You can check for further details. Umar Mujahid Pharm.D u.mujahid@yahoo.com
Can you boil aspirin into pure opium?
Of course not! There is no relationship between the two chemical compounds.
Is there aspirin in Nexium?
This drug contains absolutely no aspirin. Nexium is a proton pump inhibitor. The generic name for this drug is esomeprazole magnesium. It's effect is to reduce the amount of acid produced in your stomach and is a treatment for heartburn or indigestion. It has no relationship to aspirin.
What information can be obtained from the aspirin NMR spectrum?
The aspirin NMR spectrum provides information about the chemical structure and environment of the atoms in the aspirin molecule. This includes the types of atoms present, their connectivity, and their chemical surroundings, which can help in identifying the compound and studying its properties.
Is aspirin a element or compound?
Aspirin is a compound (2-acetoxybenzoic acid or acetyl salycilic acid).A compound. Elements are listed in the chemical element chart.
What is the relationship between physical activity and physical fitness?
The relationship between physical activity and cardiovascular activity is that physical activity changes body organs, which results in improved cardiovascular fitness. hope this helps :)
