A . Classification of Horn1ones
I. Intr du ti on T he co ncept· of inte rn al secretio ns was introdu ced by ClaNde /Jernard. He descri bed it as th e process w h reby certain. ce ll contro l vital processes and ph ys io log ical activity at remote sites by excreting o rgani c su bsta nces into tiss ue fluid. Ba)lliss and Starling later called these substances hor111ones. We recog ni se not o nly hormones which are produced by end ocrin e glands (and enter the circulation without passing through a duct), but also secretions from exocrine glands which do have ducts. The latter will not be considered in this book although the substances they produce resemble hormones in that they both, in relatively small amounts, can influence many physi ological processes by a catalyst-like action.
II. Steroid Hormones Steroid hormones are derived from 'S terane' and are soluble in fat. T hey are formed by the gonads, the adrenals and the placenta. Table

O estrogens Androgens Progestogens G lucocorticoids Mineralocorticoids
T hey can be divided into the following groups : oestrogens, progestogens, androgens, glucocorticoids and mineralocorticoids. It should be noted that some steroids belong to more than one group.
Example : D esoxycorticosterone is a mineralocorticoid whose acetate derivative has a significant progestational action.
In addition, some steroids diminish or cancel out the effect of steroids from another group, and this phenomenon depends on the dose relationship between competing substances. Example : A t higher dosage levels, p roges togens and androgens have an anti-oes trogenic effect. The la st decade has seen so marked an increase in the number of stero ids recognised that the fo llowing subclass ifica tion is appropriate :
Classification of Hormones

Strroid.r oblai11rd 0, rbemit-al reaclio11.r (e.g. csteriftcntion or attachment of a methyl gro up, an th yl gro up, or a halogen atom to o ne or more carbon atoms). Although their action and structure arc related to the parent substances in groups 1 and 2, these products do not occur naturally. Their therapeutic use is, therefore, not strictly speaking, "hormone therapy".
III. Protein Hormones Unlike steroids, these substances, which are of protein character, are soluble in water. Their synthesis and purification, made difficult by their large molecular weight have, to date, only been achieved with hormones from the posterior pituitary, with adrenocorticotrophic hormone (ACTH), and insulin.
a) Hypophyseal Hormones A probable total of 10 different hormones is found in the three parts of the hypophysis cerebri (pituitary). Hormones numbered 1, 2, 4, and 5 in Table 2 are "trophic", i.e. they control the function of other endocrine glands. By contrast, growth hormone, as well as the hormones produced by the pars intermedia and the posterior pituitary exert their action on tissues directly. The primary action Table

of prolactin (or lu teotrop hic hormone, LTH) is on the lactating breast. It is not known whether L TH has any trophic effect on the corpus lu teu m of the non-pregnant woman . In addition to the above hormones, a number of other " trophic" substances have been described e.g. diabctogenic, anti-insu lin, erythropoietic, fat-mobilising and cxophthalmic hormones. The relevant publications, some of which deal more with hypothesis than fact , have not led to universal recognition of these substances. FSH and ICSH, both of which are important in gynaecology, derived their names from their effects on gonadal function . The restricted amounts of FSH that can be extracted from human pituitaries or menopausal urine (HMG) limits the therapeutic use of these hormones.
b) Human Chorionic Gonadotrophin. (HCG) A list of protein hormones must include HCG, which is present in the urine and serum of pregnant subjects. HCG stems from the trophoblastic cells of the placenta. This hormone was originally called Prolan and the anterior pituitary was thought to be its site of production. The hormone in pregnant mares' serum (PMS) has no chemical or biological relationships with HCG. HCG, unlike the gonadotrophic hormones of pituitary origin, can be obtained in fairly large amounts. In practice HCG, rather than anterior pituitary hormone, is used to stimulate gonadal function. Whether or not "human placental lactogen" (HPL) is a further, separate protein hormone is still under debate. It is said to have luteotrophic action.
IV. Synthetic Substances with Hormone-like Actions A certain number of synthetic substances have hormonal actions although their structure does not resemble naturally-occurring hormones. They are, in a sense, substitutes, and several oestrogens are important in this respect. Stilboestrol was the first to appear, and later substances were dienoestrol, h xocstrol, benzoestrol and allenolic acid. Paraoxypropiophenone, in spite of some contradictory evidence, is a weakly oestrogenic substance (with regard to its central and peripheral act io ns). Clomiphene, known t stimulate ovulation, also belongs to this gro up.
Classification of Hormones
V. Anti-hormones 'Anti-hormones' may be formed in circumstances where a protein hormone from one species is repeatedly injected into an animal from another species. The name 'antihormones' is misleading as it implies that these substances have hormonal action. In fact, 'anti-hormones' are antibodies against foreign proteins. The fact that antibodies can be raised against protein hormones forms the basis for quantitative immunological assays
(see page 57). In humans, repeated injections of PMS or animal pi tuitary extracts (over a period of at least I month) lead to 'antihormone' production, which dimini shes the therapeutic action of the substances injected. It is said that after an interval of ;-6 months without treatment, antibodies can no longer be detected. HCG extracted from human pregnancy urine, does not lead to antibody formatio n when injected into humans.
Chem istr y of [ lormonc
B. Chemistry of Hormones
I. teroid Hormones All stero id hormones have a cycl op ·ntanophenanthrene ( tern ne) ring.
Sterane Rings A, B and C each have 6 carbon atoms while ring D has 5. The way in which the carbon atoms are numbered can be seen by studying the illustrated structure of choleste-
rol from which all steroid hormones are formed.
Except for oestrogens and aldosterone, all naturally occurring steroids possess meth I groups attached to carbon atoms 1 0 and 13 .
Chemistry of H o rmo nes
For the sake of simplicity, the chemical symbols for the methyl groups arc omi tted, but their presence is indicated by a vertica l line. Accordi ng to the number of carbon atoms they possess, we recognise C18 steroids (oestrone derivatives), C10 steroids (androstane and testane derivatives) and C21 steroids (pregnane and allopregnane derivatives).
b) Progcstogcns The naturall y ccurring luteal. hormone, progestero ne, belongs to the large group of ½i steroids which includes the adrena l hormones. This is not surprising as progesterone is no t only found in the corpus luteu m, but al so occurs as an intermed iary metabolite in the adrenal.
a) Oestrogens These are oestrone (C18) derivatives . They are characterised by an aromatic A ring, the absence of a methyl group at C10 and a hydroxyl group at ½· Of the three naturally occurring oestrogens, oestradiol is the most active. Oestrone and oestriol, which are derivatives of oestradiol and are excreted in the urine, are less active.
By a process of reduction, progesterone is converted into pregnanecliol. Although the latter is inactive, its measurement in urine is of clinical interest. HO
Oestradiol benzoate, oestradiol valerate (a depot form) and orally active ethinyl oestradiol are the substances of greatest importance in therapeutic use. OH O estradiol,3-be nzoate

Progesterone is sparingly soluble in oil, quickly broken down, and has no appreciable depot action. It thus does not satisfy the criteria demanded of hormones for modern clinical use. It was found that oestradiol and testosterone could be rendered markedly progestogenic by esterification or introduction of an alkyl (methyl or ethinyl) group. An analogous modification of progesterone was not possible and for this reason the search for other progestational steroids began relatively early. It first led to the production of pregneninolone, an orally effective substance which has since become obsolete because of its relatively weak action. Many other progestational substances have been discovered in recent years and can be arranged, according to their structure, in 6 major groups. I. Progesterone, retroprogesterone. II. D erivatives of the 17-cx-hydro:xyprogesterone esters.

The progestational action and side effects of each group are different (see page 2 r ). Substances of particular value in clinical use include 17-11.-hydroxyprogesterone-caproate from group II (a depot progestogen), 17-11.ethinyl- 19- nortestosterone-acetate from group V (tablets) and 6-chlor-6-dehydro-acetoxyprogesterone from group II (tablets).

In the ovaries, adrenals and placenta, /::J,. 4androstene-3, 17-dione, a substance closely related to testosterone is found. This substance is one of the 17-ketosteroids which are characterised by the conversion of the hydroxyl radical at Ci 7 into a ketone group.
