Terizidone
Terizidone is a drug used in the treatment of tuberculosis. Terizidone is mainly used in multi-drug-resistant tuberculosis (MDR-TB) in conjunction with other second-line drugs. It is a derivate of cycloserine Cycloserine, sold under the brand name Seromycin, is a GABA transaminase inhibitor and an antibiotic, used to treat tuberculosis. Specifically it is used, along with other antituberculosis medications, for active drug resistant tuberculosis. It ... and it is bacteriostatic.

Tuberculosis
Tuberculosis (TB) is an infectious disease usually caused by '' Mycobacterium tuberculosis'' (MTB) bacteria. Tuberculosis generally affects the lungs, but it can also affect other parts of the body. Most infections show no symptoms, in which case it is known as latent tuberculosis. Around 10% of latent infections progress to active disease which, if left untreated, kill about half of those affected. Typical symptoms of active TB are chronic cough with blood-containing mucus, fever, night sweats, and weight loss. It was historically referred to as consumption due to the weight loss associated with the disease. Infection of other organs can cause a wide range of symptoms. Tuberculosis is spread from one person to the next through the air when people who have active TB in their lungs cough, spit, speak, or sneeze. People with Latent TB do not spread the disease. Active infection occurs more often in people with HIV/AIDS and in those who smoke. Diagnosis of active TB is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Multi-drug-resistant Tuberculosis
Multidrug-resistant tuberculosis (MDR-TB) is a form of tuberculosis (TB) infection caused by bacteria that are resistant to treatment with at least two of the most powerful first-line anti-TB medications (drugs): isoniazid and rifampin. Some forms of TB are also resistant to second-line medications, and are called extensively drug-resistant TB ( XDR-TB). Tuberculosis is caused by infection with the bacterium ''Mycobacterium tuberculosis''. Almost one in four people in the world are infected with TB bacteria. Only when the bacteria become active do people become ill with TB. Bacteria become active as a result of anything that can reduce the person's immunity, such as HIV, advancing age, diabetes or other immunocompromising illnesses. TB can usually be treated with a course of four standard, or first-line, anti-TB drugs (i.e., isoniazid, rifampin, pyrazinamide and ethambutol). However, beginning with the first antibiotic treatment for TB in 1943, some strains of the TB bacteri ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cycloserine
Cycloserine, sold under the brand name Seromycin, is a GABA transaminase inhibitor and an antibiotic, used to treat tuberculosis. Specifically it is used, along with other antituberculosis medications, for active drug resistant tuberculosis. It is given by mouth. Common side effects include allergic reactions, seizures, sleepiness, unsteadiness, and numbness. It is not recommended in people who have kidney failure, epilepsy, depression, or are alcoholics. It is unclear if use during pregnancy is safe for the baby. Cycloserine is similar in structure to the amino acid D-alanine and works by interfering with the formation of the bacteria's cell wall. Cycloserine was discovered in 1954 from a type of '' Streptomyces''. It is on the World Health Organization's List of Essential Medicines. Medical uses Tuberculosis For the treatment of tuberculosis, cycloserine is classified as a second-line drug, i.e. its use is only considered if one or more first-line drugs cannot be used. ...

Imines
In organic chemistry, an imine ( or ) is a functional group or organic compound containing a carbon–nitrogen double bond (). The nitrogen atom can be attached to a hydrogen or an organic group (R). The carbon atom has two additional single bonds. Imines are common in synthetic and naturally occurring compounds and they participate in many reactions. Structure For ketimines and aldimines, respectively, the five core atoms (C2C=NX and C(H)C=NX, X = H or C) are coplanar. Planarity results from the sp2-hybridization of the mutually double-bonded carbon and the nitrogen atoms. The C=N distance is 1.29-1.31 Å for nonconjugated imines and 1.35 Å for conjugated imines. By contrast, C-N distances in amines and nitriles are 1.47 and 1.16 Å, respectively. Rotation about the C=N bond is slow. Using NMR spectroscopy, both E- and Z-isomers of aldimines have been detected. Owing to steric effects, the E isomer is favored. Nomenclature and classification The term "imine" was coined ...
