Doxycycline is a molecule of the cyclin family that works as an antibiotic by slowing the growth of bacteria in the body. It is a semi-synthetic tetracycline that was developed in the early 60s by Pfizer Inc. and marketed under the name Vibramycin, approved by the FDA in 1967. It was the first broad-spectrum daily antibiotic created and proved to be effective against intracellular bacteria.

Ampicillin (originally branded as 'Penbritin') also demonstrated activity against Gram-negative organisms such as H. influenzae, coliforms and Proteus spp.
Ampicillin was the first of a number of so-called broad spectrum penicillins subsequently introduced by Beecham. Ampicillin is part of the aminopenicillin family and is roughly equivalent to its successor, amoxicillin in terms of spectrum and level of activity.
