The following is a list of antibiotics. The highest division between antibiotics is bactericidal and bacteriostatic. Bactericidals kill bacteria directly, whereas bacteriostatics prevent them from dividing. However, these classifications are based on laboratory behavior.
It was thought that the strongest antibiotic activity of totomycin was against Staphylococcus haemolyticus, in which growth was inhibited by concentrations of 2 μg/mL.. Other gram-positive and gram-negative sensitive to totomycin are inhibited by concentrations from 16 to 31 μg/
1942 – gramicidin S, the first peptide antibiotic; 1942 – sulfadimidine; 1943 – sulfamerazine; 1944 – streptomycin, the first aminoglycoside [2] 1947 – sulfadiazine; 1948 – chlortetracycline, the first tetracycline; 1949 – chloramphenicol, the first amphenicol [2] 1949 – neomycin; 1950 – oxytetracycline; 1950 – penicillin G ...
Thienamycin (also known as thienpenem) is one of the most potent naturally produced antibiotics known thus far, discovered in Streptomyces cattleya in 1976. Thienamycin has excellent activity against both Gram-positive and Gram-negative bacteria and is resistant to bacterial β-lactamase enzymes. Thienamycin is a zwitterion at pH 7. [1]
One of the most notable scientific papers that first popularized hydroxychloroquine as a COVID-19 treatment was retracted from its journal due to ethical and methodological issues. Retractions in ...
Arsphenamine, also known as Salvarsan or compound 606, is an antibiotic drug that was introduced at the beginning of the 1910s as the first effective treatment for the deadly infectious diseases syphilis, relapsing fever, and African trypanosomiasis. [2] [3] This organoarsenic compound was the first modern antimicrobial agent. [4]
