Mode of action of penicillin: 1. Inhibition of cell wall synthesis by blocking transpeptidation: Penicillin binds to penicillin binding protein (PBP) receptor on the surface of bacterial cell wall. PBP is the receptor for substrate peptidoglycan precursor in bacteria. Antibiotics penicillin acts as alternative substrate and binds to PBP ...Streptomycin was originally purified from Streptomyces griseus. It acts by binding to 30S subunit of bacterial ribosome, leading to inhibition of protein synthesis and death in susceptible bacteria.

Penicillin was discovered by Alexander Fleming in 1928 and was first used in clinical trials in 1942.

The result showed that the inhalation of these antibiotics is a useful procedure in the treatment of tracheobronchitis, either subacute or protracted, or ...The expression ‘broad-spectrum antibiotic’ was used in the mid-1950s, when the bacterial spectrum of chloramphenicol and the first tetracyclines could be strikingly opposed to the narrow spectrum of activities of penicillin G, and streptomycin. In the 1960s, aminopenicillins, then ureidopenicillins, became the broad-spectrum penicillins in comparison with penicillin G. Until then, the ...
