Sertiirner

Figure 1. Contemporary scheme of morphine. Friedrich Sertiirner, who first isolated this alkaloid in an impure form in 1805, did know that it was converted from the pathway of tyrosine, Tyr. The correct morphine structure was determined by Gulland and Robinson in 1923. Moreover, even 200 years after Sertiirner s isolation, scientists are still discussing the synthesis of this alkaloid from a molecular point of view. This is a good example of the scientific evolution of knowledge of alkaloids.

Morphine is self-administered by Friedrich Wilhelm Sertiirner and is named after Morpheus, the Greek god of dreams, after he experiences its narcotic effects. 

The beginning of alkaloid chemistry is usually considered to be 1805 when F.W. Sertiirner first isolated morphine. He prepared several salts of morphine and demonstrated that it was the principle responsible for the physiological effect of opium, Alkaloid research has continued to date, blit because most likely plant sources have been investigated and because a large number of synthebc drugs serve medical and other needs more effectively, the greatest emphasis has been placed upon the synthetics. 

Opium contains more than 20 distinct alkaloids. In 1806, Sertiirner reported the isolation of a pure substance in opium that he named morphine. The discovery of other alkaloids in opium quickly followed that of morphine (codeine by Robiquet in 1832 and papaverine by Merck in 1848). By the middle of the 19th century, the use of pure alkaloids rather than crude opium preparations began to spread throughout the medical world. 

Sertiirner isolated morphine in 1805 [1] and its structure was determined in the early 1990s [2-4]. A myriad of derivatives were synthesized in order to obtain strong analgesics without addiction, however, the separation of... 

The isolation of morphine from opium and the recognition of the significance of its physiological effects by F. W. A. Sertiirner in 1803-1817 as well as the first definition of the term alkaloid by Meissner in 1819-1821 have led to a rapid progress in the research of alkaloids (1). In the beginning of the past century, much attention was paid to the cultivated poppy plant Papaver somniferum L., which has been used since time immemorial in popular medicine. Of the so-far known 41 opium alkaloids, only morphine, codeine, and papaverine have found...

Sertiirner s claims to have already obtained morphine in 1806 seem largely unsubstantiated, since he probably isolated what became later known as meconic acid and he unequivocally reported the isolation of a narcotic opium basic compound only in 1817. For a discussion, see F. A. Chast, in The Practice of Medicinal Chemistry, ed. C. G. Wermuth, Elsevier, Amsterdam, 3rd edn, 2008, pp. 3-62. 

Morphine was first isolated from opium in 1805 by Sertiirner, who named it after Morpheus, the Greek god of sleep and dreams. The 3-methyl ether codeine (2, Fig. 7.1) was subsequently isolated from the poppy plant Papaver...

In 1803 the German pharmacist Sertiirner succeeded in the isolation of Morphine from Opium. This event started a new epoch, focused on isolation and characterisation of pharmacologically active substances from medicinal plants. With the advent of synthetic organic chemistry, interest in the use of medicinal plants declined in Western medicine during much of the 20th century. 

Since the seminal work of Sertiirner, there were substantial efforts to elucidate the chemical structure of the principium somniferum. 

Therefore, the first report of the isolation of morphine was done by Sertiirner, and it was published in 1805. Seventy-six years after the death of... 

Sertiirner, his stone coffin was opened, and beside his mummified body was a container of 1 kg pure morphine. [3] Morphine is described in Chapter 1.10. 

In 1805 Sertiirner obtained an acid (meconic acid) by precipitating extract of opium made with ammonia with lead acetate or baryta water, and decomposing the precipitate with sulphuric acid. He found that the acid gave a red colour with ferric chloride. In a confused account he stated that opium also contains a crystalline substance forming salts with acids, which in opium is probably combined with meconic acid (Mohnsaure, Opiumsaure) the substance had narcotic properties and he called it principium somniferum . He concluded by saying that he saw Derosne s paper only when his research was... 

Before the discovery of morphine the existence of organic bases had not been suspected. Sertiirner (1817) showed that morphine forms salts with acids. Gay-Lussac then caused Robiquet to repeat and confirm the experiments, and before 1820 Pelletier and Caventou discovered strychnine, brucine, quinine, cinchonine, and veratrine. 

The first alkaloid to be obtained in the pure crystaUine state was morphine. Friedrich Wilhelm Sertiirner (1783-1841) isolated morphine in 1805. He recognized that the material possessed basic character and he, therefore, classified it as a vegetable alkali (that is, a base with its origin in the plant kingdom). Thus, compounds with similar properties ultimately became known as alkaloids. The term"alkaloid"was introduced for the first time by an apothecary, Meissner, in Halle in 1819.
