This is another way of classification of antibiotics or antibacterial agents, which is based on their target specification. In this category, the antibacterials may be either narrow or broad spectrum. The terms narrow spectrum and broad spectrum have been interpreted not specifically since their use in antibiotic history, but recently these acquired clear meanings in academic and industrial fields . The narrow spectrum antibacterials are considered to be those which can work on a narrow range of microorganisms, that is, they act against Gram‐positive only or Gram‐negative only bacteria.
- This is a very challenging environment as it is highly difficult for a software agent to perform as well as a human.
- The products that you decide you would like to sell will depend on the type of license you will need.
- Structural properties such as the number and location of various functional groups on a modified compound compared to their parent compounds usually exhibit great effect on the biological activities of these drugs.
- For example, if a principal instructs a lawyer to purchase a land for him, in that instance, the lawyer is a specific agent to the principal.
A chemical substance that produces a biological effect when administered to a living organism is known as a drug in pharmacology. When these drugs are taken in the prescribed manner to cure, prevent or diagnose a disease, it is known as medicine. Based on the effects of drugs, they are classified into four different classes based on pharmacological effect, drug action, chemical structure, and molecular targets. In several dominant drug classification systems, these four types of classifications form a hierarchy. For example, the fibrates are a chemical class of drugs that share the same mechanism of action and mode of action , and that are used to prevent and treat the same disease .
Classification of Drugs: Types, Functions & Chemical Composition
Whenever these functional roles of the cytoplasmic membrane get disturbed, macromolecules and ions will outflow, which will result in cell destruction or death. Selectivity of the agents is necessary to carry out this chemotherapy as the agents are aimed to target the bacterial cell membrane. Polymyxins are active antibacterial agents, which are cyclic peptides, having a long hydrophobic tail.
Even in sickness and diseases, people resort to medicines, again chemicals. A general agent is one who has authority to do all acts connected with a particular trade, business or employment. For instance, if a person is placed as a manager, he has authority to bind the principal for all his acts falling within the scope of the business of managing the store.

Though there may be situations where acting on one’s behalf and following their guidance is not reasonable or legal, the agent may have recourse to not follow instruction. Otherwise, the agent is bound to perform tasks as expected by the agreement. This includes situations where the principal may be disadvantaged but has instructed the agent to act in a specific manner. An agent is always tasked with acting with care and competence when handling affairs of the principal. The standard is often held that the agent must act as the principal would, using discretion as if it would incurring the personal gain or loss.
Conversely, not all PPAR agonists are fibrates, not all triglyceride lowering agents are PPAR agonists, and not all drugs used to treat atherosclerosis are triglyceride-lowering agents. Sulphonamides are one of the important class of synthetic organic compounds with great medicinal importance having a sulphonamide functional group (R1‐SO2‐NR2R3) in their structures. Some compounds belonging to this group also show antibacterial properties such as sulfadiazine. The original antibacterial sulphonamides are synthetic antimicrobial agents that contain the sulphonamide group. Some others are sulfonylureas and thiazide diuretics which proved to be newer drug groups based on the antibacterial sulphonamides . The drugs could be classified based on pharmacological and therapeutic effects.
The antibacterial agents can be classified into five major groups, i.e. type of action, source, spectrum of activity, chemical structure, and function. Unlike antibiotics classification, little efforts have been made to classify antibacterials separately. Therefore, we tried to classify antibacterial into five principal categories, each of which has its own importance. The classification mentioned could be a better guide for future classification, i.e. the agents that are in developing stages or those that are going to develop can be adjusted in any suitable group mentioned in the text. Further, this categorization could be helpful in academic and in health care fields at present and in the future as well.
A special agent is one that has been empowered to act in specific instances. For example, if a principal instructs a lawyer to purchase a land for him, in that instance, the lawyer is a specific agent to the principal. Under this classification, we have universal, general and special agents. Pharmacology is the science that studies understanding the action of drugs on the biological system and the response of the body to drugs. They are based on how they affect and minimise symptoms in the body. To become a sports agent you will need to obtain a sports license and register with the state.
The principles of chemistry have benefited human life on a massive scale though we sometimes tend to overlook them. Our clothes, some of them completely synthetic, involve processes, chemicals, dyes, and fibers. Our household is filled with detergents, soaps, bleaches, kinds of toothpaste, etc. Moreover, even the food that we consume every day has several chemicals involved. Electronic materials, fuels, explosives, rocket propellants, building materials, etc., are all considered chemicals.
On a similar note, an agent may not enter into transactions or business that compete with a principal. This conflict of interest puts the principal at a disadvantage as the agent may obtain trade or business secrets during the course of the business relationship. For example, imagine if an agent was tasked with shipping specific goods to an agent’s manufacturing warehouse. The agent could obtain information related to the principal’s operations that the agent could then use for its personal benefit. General agents are contracted to represent their clients in specific types of transactions or proceedings over a set period.
What is an Agent in Business?
Once this is complete, you will need to find an insurance company to work with. Agency by necessity is where an agent is appointed to act on behalf of a client who is physically or mentally incapable of making a decision. An agent is authorized to act on behalf of another person, such as an attorney or a stockbroker. Julia Kagan is a financial/consumer journalist and senior editor, personal finance, of Investopedia. Example of drugs, their binding sites and pathways which get affected. In compounds of this group, two aminosugars joined by glycosidic bond to an aminocyclitol.
Structurally, macrolides are antibiotics that consist of a macrocyclic lactone ring, usually 14‐, 15‐, or 16‐member to which one or more deoxy sugars, usually cladinose and desosamine, may be attached. Some well‐known examples of macrolides are erythromycin and roxithromycin etc. Calcium Channel Blockers – Calcium channel blockers are drugs that are used to lower blood pressure. Calcium movement is slowed down into the cell’s artery walls, which makes it easier for the heart to pump and dilates blood vessels. As a result, the heart doesn’t have to work as hard to pump blood, and blood pressure decreases.
Classification of drugs is very important because in the last decades, there has been an emergence of many drugs. These drugs are very diverse and their effect, chemical structure, function, and side effects vary a lot. Hence, systematic study and understanding of the classification of drugs are required. Drug classification helps to guarantee that drug use is advantageous and safe. Selling agents are types of agents who are responsible for having contractual authority for selling a service or product of the principal.
Procedures for Voluntary Winding Up of Company by Members
Aspirin, chemically known as acetylsalicylic acid, is used to reduce pain, fever, or inflammation. The process of finding a drug to a specific target location that leads to a change in its function is known as drug-target interaction. classification of agents The most common biological targets in our body are ion channels, nuclear receptors, G-protein coupled receptors, and enzymes. Some drug classes have been amalgamated from these three principles to meet practical needs.
An auctioneer has the right to keep possession of the items for the charges. He or she has the right to claim for the commission from both sides. Auctioneers also have the right to sue the price to own the name on the instructions of the principal. However, in this case, the principal becomes liable to the third parties when auctioneers act staying within the scope of the apparent authority. They are not indulged in personal business, but certainly represent the business for all the dealings. The principal-agent relationship refers to an arrangement in which one entity legally appoints another to act on its behalf.
Latter in the nineteenth century, concepts have been developed that there is the strongest correlation between bacteria and diseases. These efforts led to the revolutionary discovery of the antibacterial agent “penicillin” in 1928 from Penicillium notatum by Sir Alexander Fleming. The discovery unlocked the field of microbial natural products and so new agents were continually added, such as newly introduced daptomycin, tigecycline, linezolid, and https://1investing.in/ so on. It is aimed that this approach will be equally helpful for researchers, clinicians, and academicians. Β‐Lactam drugs, including penicillin derivatives, cephalosporins, monobactams, and carbapenems, are the major antibiotics that inhibit bacterial cell wall synthesis. Thus, β‐lactam drugs work as a false molecule for D‐alanyl‐D‐alanyl transpeptidases, which result in inhibition of transpeptidation reaction and peptidoglycan synthesis.
