The period from late 1949 through 1951 was an extraordinarily productive one in steroid chemistry and especially so at Syntex S.A. in Mexico City. Two of the most important Syntex contributions--the synthesis of 19-nor-17 alpha-ethynyltestosterone (norethindrone) and of cortisone from diosgenin--are described from a historical perspective. 
From paper chromatography to drug discovery: Zaffaroni
TLDR
A paper chromatography assay for adrenocortical steroids, published just as cortisone's therapeutic value in arthritis was announced, had far-reaching consequences, showing how steroid product development helped establish Syntex and later played a role in the founding of ALZA Corporation.
Chemical birth of the pill
TLDR
Carl Djerassi’s first synthesis of an oral contraceptive has played a critical role in the reproductive revolution of the later half of the 20th century and its societal effects, and politics and public-policy consequences have been described in a flood of articles and books.
Synthesis of clionamine B, an autophagy stimulating aminosteroid isolated from the sponge Cliona celata.
TLDR
Synthetic clionamine B strongly stimulated autophagy in human breast cancer MCF-7 cells and was strongly stimulated in mice with normal immune response to Cliona celata.
NMR spectroscopy of steroidal sapogenins and steroidal saponins: An update
The 13C NMR chemical shifts of 126 Steroidal sapogenins published between 1983 and 1993 are listed and critical spectral features and advances made in the NMR characterization of these compounds are
Chapter twelve Xochipilli updated, terpenes from Mexican plants
Summary This chapter summarizes the current knowledge of a small part of the Aztec knowledge concerning some sesqui- and diterpenes from Mexican medicinal plants. New anti-inflammatory drugs are
The mother of the pill.
  • C. Djerassi

    Recent progress in hormone research
  • 1995
TLDR
Mifepristone (RU-486) is clearly the most significant new development in birth control as an important alternative to conventional abortion.
Making British cortisone: Glaxo and the development of corticosteroids in Britain in the 1950s-1960s.
  • V. Quirke
  • Medicine
    Studies in history and philosophy of biological and biomedical sciences
  • 2005
TLDR
The varied and flexible strategy that enabled Glaxo to maintain this head start, and the scientific and technical capabilities which the company subsequently built up, enabling them to dominate the market for corticosteroids in Britain, are described.
Organocatalytic asymmetric formation of steroids.
TLDR
A novel and simple one-step approach for the construction of optically active steroids in a highly stereoselective manner by using organocatalysis is presented, which allows an easy access to opticallyactive steroids with a variety of substituents in the A ring in high yields and up to greater than 99 % ee.
Scalable synthesis of cortistatin A and related structures.
TLDR
The highly functionalized cortistatin A-ring embedded with a key heteroadamantane was synthesized by a simple and scalable five-step sequence, resulting in a core core, dubbed "cortistatinone", which was prepared for further biological studies.
Diarylheptanoids from Dioscorea villosa (Wild Yam).
TLDR
The qHNMR-aided approach enabled the identification of new and potentially significant chemical entities from a small fraction of the plant extract and facilitated the characterization of the residual complexity of the D. villosa secondary metabolome.

Early history of steroid chemistry in Mexico: the story of three remarkable men.
TLDR
This work focuses on the early days of the steroid industry in Mexico and on the three founders of Syntex, which was founded by Russell E. Marker, Emeric Somlo, and Federico A. Lehmann G.
From Ruzicka's terpenes in Zurich to Mexican steroids via Cuba
TLDR
The history of polycyclic chemistry is traced, via personal recollections, from Leopold Ruzicka's early work in characterizing terpenes to the tremendous progress in producing corticoids and estrogens from Mexican yam sterols.

A paper chromatography assay for adrenocortical steroids, published just as cortisone's therapeutic value in arthritis was announced, had far-reaching consequences, showing how steroid product development helped establish Syntex and later played a role in the founding of ALZA Corporation.
Cortical Hormones from alloSteroids: Synthesis of Cortisone from Reichstein's Compound D
TLDR
A method for the conversion of 3-keto-allosteroids into δ4-3-ketones, which involved dibromination to a 2,4-dibromo derivative, and subsequent deiodination with chromous chloride, collidine or zinc was applied successfully in the androstane, etioallocholanic acid and allopregnane series.

TLDR
The confluence of an extraordinary coalescence of multiple events and circumstances in the growth of the Upjohn Company with the Mayo discovery, inclusive of a pioneering role in the steroid field, conspired to create an environment ripe for innovation.
10-NOR-PROGESTERONE, A PHYSIOLOGICALLY ACTIVE LOWER HOMOLOG OF PROGESTERONE.
TLDR
Results indicate that the angular methyl group at C-10 can be replaced with hydrogen without impairing the physiological activity of 10-norprogesterone.
Steroid oral contraceptives.
TLDR
The history of the chemical developments which made the biological studies possible to lead to the development of the steroid contraceptive agents is reviewed and a naturally occurring plant sapogenin diosgenin is named as the most common starting material for partial synthesis in oral contraceptives.
SOME CHEMICAL AND BIOLOGICAL PROPERTIES OF 19‐NOR‐17α‐ETHYNYLTESTOSTERONE
TLDR
Norlutin and (to a lesser degree) 19-nor-17alpha-methyltestosterone exhibit an anabolic or anticatabolic action by counteracting loss in liver weight (and nitrogen) due to fasting and the possibility that suppression of pituitary secretion of gonadotropin by Norlut in may be due to contaminating 17alpha-ethinylestradiol 3-methyl ether.
