Acetylcholinesterase Enzyme Inhibitors

What has been brought to light in recent years is the effects of these chemicals on the body’s immune response. By introducing these toxic chemicals into the body, the potency of the immune system is compromised. More commonly than not, the body’s magnificent defense system will kick in and destroy foreign invaders but all it can take is an overwhelming amount of chemicals to slow or even shut down the body’s response systems. A large amount of these types of chemicals introduced into the body at one time would be considered acute toxicity and could even cause death. Additionally, a small amount of these poisonous substances brought into the body over a long period would be considered chronic toxicity and can have detrimental effects on the body’s natural response (Hoernschemeyer 55-57). This information is startling enough to want to make a change from conventionally grown food to pesticide-free organic

It was found that BChE showed broader substrate specificity when compared to AChE, hydrolysing all substrates (at least to some extent), excluding Carbachol. AChE failed to hydrolyse suxamethonium or carbachol to any extent. It was also found that Atropine and Malathion failed to significantly inhibit either cholinesterase, whereas Edrophonium displayed short-acting inhibition. Physostigmine, Nestogmine and Carbachol displayed greater inhibition.

In the early 1940’s, a new technology emerged that was able to successfully combat crop-damaging and disease-carrying insects. A new age of synthetic chemical pesticides use arose. After their impressive success in fighting deadly insect-borne diseases during World War II, pesticides were used widely to combat insect pests for agriculture and public health. Few people challenged the benefits of the new scientific and technological products and many embraced pesticide use with enthusiasm. Despite its success, doubts about pesticide use began to appear a decade later in the 1950’s, when the government began a vigorous pesticide campaign across the country against insect pests. Scientists began reporting heavy losses of avian and

The banning of insecticide, a major pollutant and neurotoxin, has been up for debate for a significant period of time. However,

Too much of the insecticides will allow acetylcholine to build up which would lead to convulsions and eventually death.

Donepezil is a reversible inhibitor of acetylcholinesterase. Reversibility of a drug, which is a pharmacology principle, is also a significant clinically characteristic. If an inhibitor is reversible, its effect on the body can be ‘turned off’ when the drug is ceased. The side effects caused by the drug may go away at the same time. There are also irreversible inhibitors of acetylcholinesterase, such as organophosphorous compound, but they are not clinically used but are used as chemical weapons or pesticides. In some cases, irreversible inhibitors can also have therapeutic effects. An advantage of irreversible inhibition is that they permanently prevent their target molecule from wreaking havoc. An example of irreversible inhibitor is beta lactam, an antibiotic. Beta lactam kill bacteria by inhibit bacterial cell wall synthesis. They bind irreversibly to penicillin-binding proteins, a group of enzymes found anchored in the cell membrane, which are involved in the cross-linking of the bacterial cell

The first ones are Cholinesterase inhibitors which communicate nerve cells and postpone deterioration for six

The first line choice in patients with heart failure is Angiotensin-Converting Enzyme Inhibitors (ACE Inhibitors). ACE inhibitors can help slow progression of heart failure and improve symptoms. ACE inhibitors block the action of a protein (enzyme) that causes blood vessels to narrow. As a result, blood vessels relax and widen. This lowers blood pressure and makes it easier for the heart to pump blood. These medicines also help body release water and sodium, which also helps lower blood pressure. ACE inhibitors relieve heart failure symptoms, such as fluid retention and edema. They may help reduce liver disease and prevent readmission to the hospital. Examples of ACE inhibitors are Captopril, Enalapril, Lisinopril, Quinapril, and Ramipril.

There are many medications on the market right now to try and help the effects of Alzheimer’s disease, many of these treat the symptoms but not the cause. One specific medication, cholinesterase inhibitors is not fully understood but it is believed to help decrease the breakdown of acetylcholine, a neurotransmitter (About Alzheimer 's Disease: Treatment, n.d.). Cholinesterase is both beneficial in it’s aid in treatment and not— this medicine over time causes neurons not to produce as much acetylcholine (About Alzheimer 's Disease: Treatment, n.d.). This drug works on mild to moderate Alzheimer’s disease because there is often a problem with synaptic activity due to TAU blockage and cell to cell connections in the genetic neuronal manifestation in Alzheimers (About Alzheimer 's Disease: Treatment, n.d.; Alzheimer 's Disease Medications Fact Sheet, 2015).

With a growing awareness of the importance of our environment, more people than ever are looking for natural products and attempting to eliminate harmful chemicals from their lives. This can clearly be seen with the move towards using bio-insecticides to kill pests in their homes. The following are three reasons to make the switch to bio-insecticides, especially for a beg bug problem.

The areas of the brain that are opulent in cholinergic neurons are vital areas for memory and learning (Hippocampus), attention and motivation (anterior cingulate), and the control of behaviours (hypothalamus). Most drugs that are used to treat AD are cholinesterase inhibitors. Cholinesterase inhibitors act by inhibiting the job of cholinesterase, they also work as an enzyme thus metabolising acetylcholine in the synaptic cleft, leading to more activity in the cholinergic synapses. Therefore the justification of using of these types of drugs is to decrease the shortage of cholinergic in synaptic diffusion thus restoring cholinergic operations or at the very least slow down the deterioration, (Parrott A, Morinan, A, Moss, M, Scholey, A. Wiley 2004).

This information is useful so that pharmaceutical researchers can understand the enzyme interactions between these drugs and the enzymes in the brain and know what to include in the new drugs they design and synthesize. Therefore, the ultimate goal of this study is to evaluate the 3D chemical structures of each of these drugs in comparison with the active sites of the enzymes they work on in order to determine what factors of the current drugs have that leads to the best enzyme interaction in order to prevent seizures in epilepsy patients in the

Chemicals that attack the nervous system are very powerful and can cause death within minutes of inhalation. Nerve agents work by blocking the transmission of nerve messages within the body (“Chemical and Biological Warfare”). “A single drop of nerve agent can shut down the entire body’s nervous system in a few minutes” (“Chemical and Biological Warfare”).

Pesticides: What are they? Pesticides are chemicals that are used to destroy pests. In the agricultural industry, pesticides are classified into two categories, carcinogenic and non-carcinogenic. A carcinogenic pesticide is a substance or agent producing or inciting cancer. Conversely, a non-carcinogenic pesticide is substance that does not produce or incite cancer. Most agricultural pesticides were registered in the 1950's, with no standard regulations. The most considerable standard prior to the amendments of the Federal Food, Drug, and Cosmetic Act (FFDCA) was, if a revocation of a pesticide occurred, would it have an impact on the prices or availability of food to the consumer? Consumer concerns with the usage of pesticides in the

Chemical weapon agents, are organized into several categories according to the physiological manner in which they
