Syntex

<h2 id="prominent-researchers">Prominent researchers</h2>
<ul><li><a href="/facts/Russell_Earl_Marker/g6hWAgHc">Russell Marker</a> co-founded the company in 1944. In May 1945, realizing that he was being left out of the company's profits, he left the company. When Marker took his notebooks with him, production was severely hampered because he had done the synthesis himself and had coded the reagent bottles.</li>
<li><a href="/facts/George_Rosenkranz/HcHgt7AT">George Rosenkranz</a> had studied at the Swiss Federal Institute of Technology and was conducting pharmaceutical research in Cuba.<a class="footnote-ref" id="fnref:9" href="#fn:9">9</a> He joined Syntex in 1945 to replace Marker. He hired Djerassi in 1949.</li>
<li><a href="/facts/Carl_Djerassi/JboqQ6yh">Carl Djerassi</a> went to work at Syntex in 1949 as the associate director of chemical research. He remained there through 1951, leaving to join the faculty of the Chemistry Department at Wayne State University (Detroit, Michigan) starting in 1952. He later returned to the company in 1957, was involved in the company's move to Palo Alto (where he had become a professor of chemistry at Stanford in 1960), and stayed around this time until 1972.</li>
<li><a href="/facts/Alejandro_Zaffaroni/jsW0BRDR">Alejandro Zaffaroni</a> developed procedures for identifying and separating steroids using paper chromatography while studying at the University of Rochester, and joined Syntex as a research biochemist in 1951. He became vice-president in 1956, and was appointed president of Syntex's U.S. subsidiary in Palo Alto, California in 1962.</li>
<li><a href="/facts/Luis_E._Miramontes/4Pp2wm89">Luis E. Miramontes</a> moved from <a href="/facts/UNAM/D0s6Ez5c">UNAM</a> to Syntex in 1950 as a researcher under Djerassi. Under the direction of Djerassi and Rosenkranz, he performed the last step of the first synthesis of an orally highly active <a href="/facts/Progestin/8xMJYV3A">progestin</a> on 15 October 1951. The semi-synthetic steroid, norethisterone (19-Nor-17-alpha-ethynyltestosterone), was the first orally highly active progestin, which led to the development of the first <a href="/facts/Combined_oral_contraceptive_pill/Wudd4dH7">oral contraceptive pills</a>.</li>
<li>Albert Bowers joined Syntex, in 1956 as research group leader; went on to publish more than 90 scientific papers on steroid research and originated more than 120 U.S. patents. Bowers became president of Syntex in 1976, was chief executive officer from 1980 to 1989 and had served as chairman of the board, 1981-1990.</li>
<li><a href="/facts/Jerzy_Rzedowski/yBSW5yq8">Jerzy Rzedowski</a> worked as an explorer botanist. He later became the most prominent plant scientist in Mexico.</li>
<li><a href="/facts/Ralph_Dorfman/0M370Gaw">Ralph Dorfman</a> Joined the company as a consultant in 1960, eventually serving as President of Syntex Research from 1967–1973</li></ul>
<h2 id="birth-control-pill">Birth control pill</h2>
Syntex submitted its compound to a laboratory in <a href="/facts/Madison,_Wisconsin/jcVnNquB">Madison, Wisconsin</a>, 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, <a href="/facts/G.D._Searle_%26_Co./6HXTxY32">G.D. Searle & Co.</a> filed for a patent for the synthesis of the double-bond isomer 13 of norethindrone called <a href="/facts/Noretynodrel/lPI8CYgI">noretynodrel</a>. Noretynodrel is converted into norethisterone under acidic conditions, such as those in the human <a href="/facts/Stomach/Q4PPDGT6">stomach</a>, 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, <a href="/facts/G.D._Searle/6HXTxY32">G.D. Searle</a>, and <a href="/facts/Johnson_%26_Johnson/DSfqnVrM">Johnson & Johnson</a> under the <a href="/facts/Ortho_Pharmaceutical/0G5HSFME">Ortho Pharmaceutical</a> brand, were marketing 2-mg doses of the Syntex norethindrone.

<h2 id="scientific-misconduct">Scientific misconduct</h2>
Syntex's submission of a fraudulent toxicology analysis of <a href="/facts/Naproxen/2oJdSCWq">naproxen</a> largely led to the <a href="/facts/Food_and_Drug_Administration/rCEnh9WB">Food and Drug Administration</a>'s uncovering of extensive scientific misconduct by <a href="/facts/Industrial_Bio-Test_Laboratories/TxHpsxGr">Industrial Bio-Test Laboratories</a> in 1976.<a class="footnote-ref" id="fnref:10" href="#fn:10">10</a><a class="footnote-ref" id="fnref:11" href="#fn:11">11</a><a class="footnote-ref" id="fnref:12" href="#fn:12">12</a><a class="footnote-ref" id="fnref:13" href="#fn:13">13</a>
