What are beta lactams?

1. Definition

β-lactam antibiotics refer to a large class of antibiotics with a β-lactam ring in the chemical structure, including penicillin and its derivatives, cephalosporins, monoamide rings, carbapenem and penicillin enzymes Inhibitors and other atypical β-lactam antibiotics such as newly developed cephamycins, thiomycins, monocyclic β-lactams, etc. 

Basically all antibiotics including β-lactam core in their molecular structure belong to β-lactam antibiotics. It is the most widely used class of existing antibiotics.

2. Mechanism of action

The action mechanisms of various β-lactam antibiotics are similar, and they can inhibit cell wall mucopeptide synthase, that is, penicillin binding protein, thereby hindering cell wall mucopeptide synthesis, causing bacterial cell wall defect and bacterial swelling and cracking. 

In addition, lethal effects on bacteria should include triggering the autolytic enzyme activity of the bacteria, and mutant strains lacking autolytic enzyme show drug resistance. Mammals have no cell wall and are not affected by β-lactam drugs. Therefore, this class of drugs has a selective bactericidal effect on bacteria and is less toxic to the host.

3. Classification

These include penicillin and its derivatives, cephalosporins, monoamide rings, carbapenems and penicillinase inhibitors, as well as newly developed cephamycins, thiomycins, monocyclic β- Lactam and other atypical β-lactam antibiotics.

4. Uses

β-lactam antibiotics are available in both injection and oral dosage forms, and are easy to use. It is widely used clinically, and bacterial infections in various parts of the human body can be treated almost, including bacterial infections of the respiratory system, digestive system, urinary system, reproductive system, facial features, cerebral nervous system, skin and soft tissues, bones and joints.

What are tetracyclines?

1. Definition

Tetracyclines are a class of broad-spectrum antibiotics produced by actinomycetes, including chlortetracycline, oxytetracycline, tetracycline, and the semi-synthetic derivatives metoxycycline The structure of cyclamycin, dimethylaminotetracycline, etc. contains naphthylphenyl skeleton.

2. Mechanism of action

The mechanism of action is that the drug can specifically bind to the A position of the 30S subunit of the bacterial ribosome, preventing the connection of the aminoacyl-tRNA at this position, thereby inhibiting the growth of the peptide chain and affecting bacterial protein synthesis.

3. Classification

Tetracycline antibiotics mainly include chlortetracycline, oxytetracycline, and tetracycline. Tetracycline antibiotics have a common chemical structure. Both chlortetracycline and oxytetracycline are derivatives of tetracycline, the former is chloretracyelin, the latter is oxyeracyein, and the tetracycline family are both acid-base amphoteric compounds.

4. Uses

For the diagnosis of malignant tumors; for various cysts; for the treatment of intractable pleural effusion and effusion; for the treatment of bronchopleural fistula; for the treatment of axillary odor; for the treatment of internal hemorrhoids; for the treatment of rosacea; bullous pemphigoid; for the treatment of acute acne Pityriasis lichenoid; treatment of acne; for the clinical treatment of rickettsial disease, chlamydia disease, mycoplasma disease, spirochete disease.

What are sulfonamides?

1. Definition

Sulfonamide, also known as diaminosulfonyl, thioamide. The chemical formula SO2 (NH2) 2. The molecular weight is 96.11. Orthogonal plate-like crystals can absorb dry ammonia gas at room temperature to form a colorless ammonia complex, which is stable in acidic, neutral and alkaline aqueous solutions.

2. Mechanism of action

Bacteria cannot directly use the folic acid in their growing environment, but use the p-aminobenzoic acid and dihydroiodine tincture in the environment. Dihydrofolate of glutamic acid in the enzyme body synthesizes dihydrofolate under the catalysis of synthetase. Under the action of dihydrofolate reductase, tetrahydrofolate is formed. As a coenzyme of one-carbon unit transfer enzyme, tetrahydrofolate participates in the synthesis and synthesis of synthase precursors, and synthase is an essential component for bacterial growth and reproduction.

The chemical structure of sulfa drugs is similar to that of PABA. It can compete with PABA for dihydrofolate synthase, which affects the synthesis of dihydrofolate, thus inhibiting the growth and reproduction of bacteria. Because sulfa drugs can only inhibit without sterilization, they eliminate the body Pathogens ultimately depend on the body's defense capabilities.

3. Classification

A. Sulfa drugs that are easily absorbed by the intestinal tract. Mainly used for systemic infections, such as sepsis, urinary tract infection, typhoid fever, osteomyelitis, etc. According to the length of drug action time, it is divided into short-acting, medium-acting and long-acting categories. The short-acting type absorbs quickly in the intestine and excretes quickly. The half-life is 5 to 6 hours and needs to be taken 4 times a day. The half-life of the medium-acting type is 10 to 24 hours and 2 times a day. More than hours.

B. Sulfa drugs that are difficult to absorb in the intestine. Can maintain a high drug concentration in the intestine. Mainly used for intestinal infections such as dysentery and enteritis.

C. Topical sulfa drugs. Mainly used for burn infection, suppurative wound infection, ophthalmological diseases, etc.

4. Uses

A. epidemic cerebrospinal meningitis;

B. urinary tract infection;

C. respiratory tract and pharyngeal infection;

D. intestinal infection;

E. local infection.

The hazards of Betalactam, Tetracycline and Sulfonamides

If the egg containing antibiotics is eaten for a long time, the sensitive bacteria in the body will be killed or suppressed, but the resistant bacteria will multiply, which will break the original balance and cause long-term diarrhea or malnutrition. In severe cases, it can also cause resistant bacteria. infection.

Regularly eating egg containing antibiotics is equivalent to long-term absorption of low-dose antibiotics. On the one hand, it can cause some pathogens in the body to gradually become resistant to multiple antibiotics; on the other hand, antibiotics can be selected in dairy farms. Drug-resistant bacteria may enter the human body through food, and then transfer drug-resistant factors to sensitive bacteria in the human body.

When antibiotics were first used on humans, we regarded them as "elixir". As the problem of antibiotic abuse continues to worsen, their resistance has also brought huge harm to humans.

Therefore, in daily life, we should avoid food with antibiotic residues. The first step to self-help: we need to detect antibiotic residues.
