How did Alexander Fleming discover antibiotics?
Alexander Fleming’s Discovery After isolating the mold and identifying it as belonging to the Penicillium genus, Fleming obtained an extract from the mold, naming its active agent penicillin. He determined that penicillin had an antibacterial effect on staphylococci and other gram-positive pathogens.
Who invented amoxicillin?
Amoxicillin was discovered by scientists at Beecham Research Laboratories in 1972. The narrow spectrum of antimicrobial activity of the penicillins, led to the search for derivatives of penicillin which could treat a wider range of infections.
Why did Fleming discovered penicillin?
An uncovered Petri dish near an open window became contaminated with mold. Fleming realized that the bacteria near the mold were dying. He isolated the mold and identified it as Penicillium genus, which he found to be effective against all Gram-positive pathogens.
What did Alexander Fleming do during the First World War?
During World War I, Fleming had a commission in the Royal Army Medical Corps and worked as a bacteriologist studying wound infections in a laboratory that Wright had set up in a military hospital housed in a casino in Boulogne, France.
How is sulfonamide created?
Sulfonamides are prepared by the reaction of a sulfonyl chloride with ammonia or an amine. Certain sulfonamides (sulfadiazine or sulfamethoxazole) are sometimes mixed with the drug trimethoprim, which acts against dihydrofolate reductase.
How did Florey and Chain mass produce penicillin?
Purification and Trials Florey and Chain were interested in Alexander Fleming’s work and in 1938, began studying the antibacterial properties of mold. Chain began by purifying and concentrating the penicillin “juice” through a complex and tiring process of freeze drying the product repeatedly.
What was the first drug to be discovered?
Some of the earliest evidence of Cannabis use dates back to around 8000 BCE, making it the oldest drug ever discovered. Cannabis is also considered one of humanity’s oldest cultivated crops. Like the other drugs on this list, Cannabis was initially used for medicinal purposes, such as an anesthetic during surgery.

What is antibiotic classification?
Antibiotics can be divided into two classes based on their mechanism of action. Bactericidal antibiotics kill bacteria; bacteriostatic antibiotics inhibit their growth or reproduction. One way that bactericidal antibodies kill bacteria is by inhibiting cell wall synthesis.

Chloromycetin, the first synthetic antibiotic.
What is the mechanism of action of sulfonamides?
Mechanism of Action The sulfonamides inhibit the bacterial enzyme dihydropteroate synthetase (DPS) in the folic acid pathway, thereby blocking bacterial nucleic acid synthesis. Sulfonamides substitute for PABA, preventing its conversion to dihydrofolic acid. Alone, this action is considered bacteriostatic.
