History
Abelardo Aguilar, a Filipino scientist, sent some soil samples to his employer Eli Lilly in 1949. Eli Lilly’s research team, led by J. M. McGuire, managed to isolate erythromycin from the metabolic products of a strain of Streptomyces erythreus (designation changed to "Saccharopolyspora erythraea") found in the samples.
Lilly filed for patent protection of the compound and U.S. patent 2,653,899 was granted in 1953. The product was launched commercially in 1952 under the brand name Ilosone (after the Philippine region of Iloilo where it was originally collected). Erythromycin was formerly also called Ilotycin.
In 1981, Nobel laureate (1965 in chemistry) and Professor of Chemistry at Harvard University (Cambridge, MA) Robert B. Woodward (posthumously), along with a large number of members from his research group, reported the first stereocontrolled asymmetric chemical synthesis of erythromycin A.
The antibiotic clarithromycin was invented by scientists at the Japanese drug company Taisho Pharmaceutical in the 1970s as a result of their efforts to overcome the acid instability of erythromycin.
Scientists at Chugai Pharmaceuticals discovered an erythromycin-derived motilin agonist called Mitemcinal that is believed to have strong prokinetic properties (similar to erythromycin) but lacking antibiotic properties. At the present time, erythromycin is commonly used off-label for gastric motility indications such as gastroparesis. If Mitemcinal can be shown to be an effective a prokinetic agent, it would represent a significant advance in the GI field as treatment with this drug would not carry the risk of unintentional selection for antibiotic-resistant bacteria.

Famous quotes containing the word history:
“It gives me the greatest pleasure to say, as I do from the bottom of my heart, that never in the history of the country, in any crisis and under any conditions, have our Jewish fellow citizens failed to live up to the highest standards of citizenship and patriotism.”

“Racism is an ism to which everyone in the world today is exposed; for or against, we must take sides. And the history of the future will differ according to the decision which we make.”
—Ruth Benedict (1887–1948)
“The basic idea which runs right through modern history and modern liberalism is that the public has got to be marginalized. The general public are viewed as no more than ignorant and meddlesome outsiders, a bewildered herd.”
