    Description
    Mexico and Panama. Syntex Corp., 1950s 100 Shrs Specimen Stock Cert., VF-XF SCBN Green. Historic Birth Control Manufacturer. Laboratorios Syntex SA was a pharmaceutical company formed in Mexico City in 1944 by Russell Marker to manufacture therapeutic steroids from the Mexican yams. Syntex submitted its compound to a laboratory in Madison, Wisconsin, for biological evaluation, and found it was the most active, orally-effective progestational hormone of its time. Syntex submitted a patent application in November 1951. In August 1953, G.D. Searle & Co. filed for a patent for the synthesis of the double-bond isomer 13 of norethisterone called noretynodrel. Noretynodrel is converted into norethisterone under acidic conditions, such as those in the human stomach, and the new patent did not infringe on the Syntex patent. Searle obtained approval to market noretynodrel before Syntex received its approval. By 1964 three companies including Syntex were marketing 2-mg doses of the Syntex norethisterone.
