Phospholipids

This is the second of two articles onlecithin by Armin Wendel. managingdirector of Nattennann PhospholipidsGmbH in Cologne, Gennany. This arti-cle describes the expansion of rommer-cial lecithin activity into a global phar-maceutical industry. This first article,which appeared in the August 2000issue of inform, ccoered the discoveryand early commercialization of lecithin.

I«j

In the United States, the early focus ofthe soybean processing industry hadbeen mainly on the manufacture of soyoil. Soy protein was a welcome by-product as a source of protein, particu-larly for animal feeds, but also for food-stuffs. Lecithin was an interesting by-product that was offered in differentforms (bleached or modified) for use asan emulsifier in the food industry.

In Europe, the particular focus ofinterest was on the therapeutic use oflecithin. Even prior to 1910 there werevarious pharmaceutical products on themarket that contained lecithin. HeinrichCarl Buer (1875-1962) (Figure I), inparticular, had conducted a great dealof research on lecithin. In 1905, heestablished the C.H. Buer chemical andpharmaceutical factory in Bonn; it waslater moved to Cologne. H.C. Buer and

later his son, Carl Heinz Buer(1907-1964) (Figure 2), were convincedof the therapeutic benefits of lecithin,especially in improving physical and

mental performance. Considering ovo-lecithin to be too expensive, H.C. Buersought to produce lecithin from plantmaterial. Soybeans were not available inGermany at the time. He tried to pro-duce lecithin from lupins, with a goal ofproducing the purest possible oil-freelecithin.

From 1905 to 1960, the Buer organi-zation registered more than 20 patents(Table 1). However, it was not until

after 1910, when the Hansa Mill wasable to produce large quantities of soylecithin, that Buer succeeded in creatingsuitable products from a plant rawmaterial. His product, BuersReinlecithin, was introduced onto themarket in the 1930s and becameextremely popular. h was the first 50-

called de-oiled lecithin to be producedcommercially.

In 1941, Rudolf Kunze, in collabora-tion with the elder Buer, published acomprehensive book summarizing allthe knowledge which had been pub-lished up to that time relating particu-larly to the physiology and possibletherapeutic applications of lecithin (1).After World War Il, the Buer firmbrought additional lecithin productsonto the market, which are still knowntoday under the trade name ofBuerlecithin. In the 19605, the C.H.Buer chemical and pharmaceutical fac-tory was taken over by the Pfizer com-pany which continued to manufacturelecithin under the trade nameReinlecithin-Pfizer into (he 1980s.

pfizer then ceased producing its ownlecithin, and the rights to theBuerlecithin product were acquired bythe Roland (Byk-Gulden) company.Lipoid KG acquired the productionplant for the manufacture ofReinlecithin.

Another pharmaceutical chemist,Hans Eikermann (born in 1910), alsoconducted research in Cologne on eve-lecithin (lecithin ex 0110) in the 1930s(2). Within a few months after the our-

break of World War 11, egg yolk pow-der, which was imported from China,was in noticeably shore supply.Eikermann looked around for a replace-ment and remembered his reacher, Prof.Hans-Paul Kaufmann (1889-1971) atthe University of Miinster, who, in hiscourse on technology and large-scaleindustry, had talked about the soybeanfrom which the commercial productlecithin was produced, and had men-tioned that large quantities of lecithinwere manufacrured as a byproduct atthe Hansa Mill. In his first laboratoryattempts to purify soy lecithin to pro-duce a quality similar to that of "avo-lecithin purissimum," Eikermann dis-covered that the fatty acid compositionof soy lecithin differed from that of ovo-lecithin. A comparison of the iodinevalue (indicating the degree to which afat is unsaturated) showed 6()...64 in thecase of ovo-lecirhin while soy lecithinhad an iodine value of 84-87 (Table 2).

It turned out that the lecithin whichEikermann had isolated contained ahigh percentage of choline phospho-lipids with a surprisingly high percent-age of polyene acids (polyunsaruratedFarry acids).

World War U prevented furtherresearch, and it was nor until the end ofthe 1940s that Eikermann was able toresume his work. Researchers at theInstitute of Physiological Chemistry atthe University of Cologne were thenable to elucidate [he structure of this"new lecithin." It was a lecithin withover 70% phosphatidylcholine (PC)and a high percentage of "essential"fatty acid: linoleic acid (dilinoleoylphos-phatidylcholine). The new compoundwas referred to as an EPL (EssentialPhosphoLipid) substance. Later the EPLwas further purified until a PC percent-age of over 90% was attained, whichwas called PPC (PolyenylPhospharidyl'Choline}, Extensive phar-macological and clinical tests showedthat PPC was effective in treating casesof lipoparhies and liver disease (3-8).

A Cologne, Germany, company, A.Nartermann &. Cie. GmbH, developedand brought onro the market a series ofpharmaceutical products for oral, topi-cal, and parenteral administrationunder the brand names of Lipostabil,Lipogeron, Essenriale, and Essaven. 1.norder to manufacture the new PC frac-tions, suitable processes had to be devel-oped and were patented (Table 3),which led to the construction of large-scale fractionating plants. Today, theseplants have a capacity of more than 500tons of Pc.

In Hamburg, which could be ccnsid-ered the birthplace of lecithin, anothercompany, the Lucas Meyer (9) compa-ny, was dedicating itself to lecithinproducts. The Lucas Meyer (LM) com-pany had been established in 1923 by

Volume I I - September 2000 • Inform

Captain Lucas H.H. Meyer, who wasthen 30 years old and had traveled theworld on a tramp steamer. The goal ofhis company was to distribute specialpharmaceutical products in SouthAmerica and Africa. During the 19205and 19305, LM had distributed a num-ber of pharmaceutical products contain-ing lecithin (Domesex, Domecalcium,and Domechinin, from the firm Chern.Fabrik Dr. Meyer Casrens & Co.GmbH). However, World W:lr II hadcur off the firm's trade roures and theraw materials needed to resume phar-maceutical production were in shortsupply after the war.

In response to U.S. offers of postwareconomic aid, the founder's son, LucasH.G. Meyer, decided to try importing alimited amount of lecithin. To be on thesafe side, he applied for twenty times[he amount he actually needed, as allquantities in aid applications usuallywere reduced time and again beforethey were finally approved. The U.S.soybean processors, however, had largestocks of this by-product lecithin, so theactual amount applied for wasapproved-and supplied. As a result,the LM company was suddenly facedwith having to find ways ro sell lecithinOUTsidethe pharmaceutical industry. In1948, there was no market yet for thelight-colored U.S. lecithin, as LM's cus-tomers were familiar only with the darklecithin from Manchurian soybeans. Toensure that the product could still besold, an old German army "goulashgun," a mobile field kitchen, wasbrought in to save the day. Against thefirm's managers' better judgment, theperfectly good, tight-colored lecithinwas "refined" to turn it into darklecithin, since mat was apparently whatthe market demanded.

The company rapidly made a namefor itself around the world. It success-

fully sought new applications in allareas of the food and animal feedstuffsindustry as well as in the engineering,cosmetics, and dietetics industries.Lucas H.G. Meyer employed me youngVolker Wywiol, who successfully mar-keted the company's products. The oilmills were pleased to have found a com-pany that could market their by-prod-ucts. In time, Lucas Meyer became theworld's largest lecithin marketing com-pany-the company and its staff wereproud to call themselves "The LecithinPeople." In '1999, the company wassold to SKW Trosrberg AG, in whichViag AG has a majority interest. WhenLucas H.G. Meyer and his son died inthe late 1970s, a transition to the nextgeneration was not without its difficul-ties. Volker Wywiol and HerbertRebmann left [he company to set uptheir own companies.

Volker Wywiol founded SternChemie, which successfully built up anew lecithin business based on theStern-Lecithin line of products. (10). In1992, Wywiol and Central Soya Inc.(CSY) agreed on a cooperation arrange-ment under the new company name ofStern Lecithin & Soja GmbH & Co. KG(11). In 1999, the whole companypassed inro the ownership of CSY.

In 1978, Herbert Rebmann estab-lished Lipoid KG in Papenburg, latermoving the company to Ludwigshafen,Germany. There, he built up his ownproduction facility with the aim of man-ufacturing high-purity phospholipidsfrom egg yolk and soybean lecithin forthe pharmaceutical industry. Lipoid AGhas become one of the world's majormanufacturers of high-purity phospho-lipids.

There is one other company thatshould not be forgonen: Unilever( 12-14). As was mentioned earlier, themargarine industry had a strong

demand for lecithin. Unilever, asEurope's largest margarine producer,was continuously looking at ways offurther develop-ing margarineproducts and ofusing lecithin infood. The switchfrom batch tocontinuous mar-garine produc-tion in the 19605led to a shortageof commerciallecithin for stabilizing emulsions. TheUnilever research group underHermann Pardun developed new emul-sifiers for margarine based on ethanol-soluble lecithin fractions (PC contentapproximately 33%), with a PC fO PE(phosphatidylethanolamine) ratiogreater than 4 (covered by Germanpatents DE 1,492,952, 1963 and DE1,692,568.1967). ln The Netherlands,a factory was built to produce this alco-hol-soluble fraction and was designedto process up to 1,000 metric rons ofsoy lecithin (15,16). The factory is stilloperating. The products were soldunder the brand name Boice. Unileveritself has largely withdrawn from themanufacture of commodity products,such as soy oil or soy proteins, and hassold all its oil mills.

From PC to the liposomeIn the 1960s, English scientists conduct-ed research on the structure of phos-pholipids. Such research had been madepossible by improved microscopy tech-niques. Bangham and Hom observedunder the electron microscope thataqueous phospholipid dispersions spon-taneously form multilayer vesicle sys-tems which in terms of their srrucrureare reminiscent of onionskins (17,18).Sessa and Weissmann later called these

vesicles "liposomes'' (19). Even thoughthe term liposome was new, many scien-tists previously had observed anddescribed such phenomena. From asearly as 1885 onward, Professor OttoLehmann (20) had been studying liquidcrystals at the Technical University inKarlsruhe. During 1910-1912, he pub-lished several papers describing theresults of experiments in which headded water to alcoholic lecithin solu-tions and observed under the micro-scope the formation of spherical struc-tures. He also described the latter asartificial cells. Numerous patent appli-

cations filed between 1910 and 1940also describe the manufacture oflecithin emulsions and dispersionswhich, based on current knowledge, wewould refer to as liposornes (21).

In any event, Bangham's publicationstriggered a research boom. Scientistsbelieved that they had found a medical"Trojan Horse" that could channel sub-stances through the body precisely towhere they were supposed to producetheir effect, thus avoiding undesirableside-effects on other organs. These lipo-somes are composed of the same phos-pholipids that are major constituents of

the body's cell membranes. Because ofthis similarity, liposomes should haveno toxic effect. Unfortunately, thingshave not proven as simple as had beeninitially hoped.

The pharmaceutical industry con-ducted research on liposomes, and thefirst patent was registered in 1973(German patent DE 22,49,552 issued toInchema SA). Both established and newcompanies prepared to manufacturenewly defined phospholipids. Somecompanies were set up specializing sole-ly in Hposome technology. Success wasslow in coming and, as a result, theinterest shown by the pharmaceuticalindustry waned.

In the 1980s, the cosmetics industryadopted liposome technology. The com-panies L'Oreal and Dior introducedtheir brands Niosome and Capture,respectively, onto the market. Althoughthis brought enormous movement intothe cosmetics market (there is no cos-metics company today which does nothave at least one liposome product in itsrange) (22), it did not create any newdimension for the pharmaceuticalindustry. However, research in this fieldcontinued with undiminished vigor andthe flow of publications continuedunabated (Figure 3). Liposome advo-cates, such as Bangham, Gregoriadis,Osrro, Pepahadjopoulcs, Saoka,Crommelin, Juliano, Lasic, and Janoff,among others, wrote review articles andbooks and held various liposome con-ferences. In a book, D.O. Lasic (23)takes a critical look at the past as wellas discussing future prospects. A bookby F. Puisieux of the University of Paris(24) includes a section emirled "TheLiposome Stcry," a comprehensive his-torical summary of this still youngbranch of research that lists 12 booksand 45 review articles on liposomes, allpublished between 1987 and 1993.

Although the pharmaceurical indus-try had viewed liposomes with someskepticism, in the 1990s three compa-nies succeeded in bringing liposomeproducts onto the market. In so doing.they have reawakened interest in lipo-somes.

The Liposome Company (TLC).which was established in Princeton, NJ.in 1981, brought Abelcet (amphotericinlipid complex) onto the market in 1995.

NeXstar Pharmaceutical Inc.,which was established in 1981 asVesrar lnc., brought liposomal ampho-rericin (AmBisome) onto the market in1990 and Hposcrnat daunorubicin(DaunoXome) onto the market in1996. NeXstar merged with GileaDPharrnaceuricfA Inc. in 1999.

Sequus Pharmaceuticals Inc., whichwas established as LiposomeTechnology in 1981 and was acquiredby Sequus in 1995, brought ampho-tericin (Amphocil) OntO the market in1994 and doxorubicin (Doxil) in 1995.In 1998, Sequus was acquired by AlzaCorp.

The futureOne hundred fifty years havepassed since lecithin was identifiedin the human brain by MauriceGobley. Today, every biochemistrytextbook describes lecithin as amixture of several phosphorus-con-taining substances collectivelyknown as phospholipids and dis-cusses their role in biologicel rnem-brcues.

As outlined earlier, the history oflecithin and PC has been a successfulone, leading ro an ever-increasingdemand for these substances in severalfields of application. However, in con-trast to this commercial and technicalsuccess, the stare of the art in basicresearch, and particularly in biochem-istry, has not kept pace. Conremporaryknowledge of the human organism isnot sufficient to explain the beneficialeffects of PC in a wide variety of appli-cations.

In short, we are probably doing theright thing by applying lecithin and PCto ourselves, bur we do not know whatis behind it. Even more disturbing is thefact that, due to our lack of knowledge

on the role of lecithin in various bio-chemical processes, we might be missingthe chance to prevent human diseasesfor which a cure is currently not avail-able.

Here we outline the questions whichmay justify optimism about futuredevelopments and research that shouldlead to the full recognition of the signif-icant role of lecithin in the improvementor human health,

The most fascinating and perhapsmost puzzling facr is [hat currentlylecithin and PC are used on the onehand as inert. nontoxic emulsifiers orliposome-forming agents, and on theother hand as dietetics and active drugsubstances. These diverse, and at a firstglance contradictory, fields of func-tionaliry are unique to lecithin and Pc.No other blomolecule is being used asa margarine or chocolate emulsifier,

teet the liver against the consequencesof alcohol abuse.

Today it is known that PC is meta-bolically connected to other biornole-cules possessing the same trimethyl-substituted quaternary nitrogen atom.PC can yield choline which can thenbe further converted into glycinebetaine, a methylating agent involvedin the biosynthesis of the essentialamino add, L-methionine; this chainof transformations also can run in theopposite direction. However, the logicand significance of these transforma-tions are nor yet understood.Nevertheless, the unique position ofPC is that it is the most stable andmost abundant of these biomolecules.It may be termed the mother of thesesubstances.

'"

The full importance of this pictureis documented by the finding {hatdiets deficient in lecithin or in thesesubstances spontaneously lead to alack of biological energy and possibleinduction of liver cancer. PC and therelated biomolecules are thereforeessential components of our diet.Based on these findings, we can con-clude that PC must be fulfilling yetanother function which is not that ofbeing merely the building unit of inertbiological membranes.

Despite these results, which havean important bearing on human life,we still do nor know how muchlecithin we need in our daily dietwhen we feel good, or when we areill, when we are young, or when weare in the second or third phase ofour life. It is our belief that futureknowledge about the role and func-tion of lecithin and PC in our bodywill lead to a new age, not only in thehistory of lecithin but also in the pre·vention of human diseases, thusimproving the quality of life.
