CH0 25 I 2 co-nh-ch2-ch2-so2oh og som har et bredt terapeutisk og præventivt virkningsspektrum over for sygelige forandringer der.
30 kan føres tilbage til beskadigelser af "AGAS" (det aerobiosfæri-ske genetiske adaptionssystem). #
Til belysning af begrebet "AGAS" opregnes i det følgende de vigtigste væv og organer der danner dette system.
a) Alle biologiske grænseflader der står i berøring med 35 den ydre luft som biosfæren (hud og huddannelser, øjets hornhinde og Conjunktiva, mund- og svælghulrum, luftveje og lunge); b) skelet og led (rørknogler og svampeagtige knogler, kugleled, synoviale membraner, skeletmuskulatur); 2
DK 159267 B
c) de til reguleringen af ionhusholdningen deltagende organer (transepiteliske transportsystem: tarmtrævler og nyrekanal) ; d) det til findeling af næringen nødvendige tekodonte 5 (i tandaveolerne med rødder fastgjorte) tandsæt; e) høre-, lugte- og stemmeorganer.
De omhandlede forbindelser udøver således en gunstig biologisk eller terapeutisk virkning på de her opregnede organer eller væv af AGAS-systemet.
10 De ved fremgangsmåden ifølge opfindelsen fremstillede forbindelser virker desuden på følgende funktioner der står i sammenhæng med AGAS-systemet: strålingsbeskyttelse, begunstigelse af sårheling, almindelig aktiverende virkning på mesenkym, beskyttelse mod den stadigt voksende infektions- og tilsmudsnings-15 fare hos hud og slimhinder (den fugtige slimhindes lysozymproduk-tion, aktivering af fimreepiteler i luftvejene osv.), forøget beskyttelse mod de af vira og svampe forårsagede infektioner.
De ved fremgangsmåden ifølge opfindelsen fremstillede forbindelser er virksomme mod de stadigt og i høj grad stigende 20 stress-virkninger der er knyttet til livet på fastlandet (fx meteorologisk indflydelse, store forskelle mellem dag- og nattemperatur, forhøjet fare for kvæstelser), idet de stabiliserer adaptionssyndromet og samtidigt afværger glukokortikoidernes perifere vævsskader (som fx skader i bindevævet, kvæstelser af 25 knoglematrixbestanddele osv.). Udvikling af immunhomøostase (stigende erkendelsesevne hos legemet om hvilke celler der er kropsegne og hvilke der ikke er).
De ved fremgangsmåden ifølge opfindelsen fremstillede forbindelser udøver deres virkning dels umiddelbart, dels over 30 reguleringen af vitamin A metabolismen, ved produktion af vitamin A metaboliter med stærkere polær karakter. Denne virkning kan sammenlignes med parathormonets virkning på 25-hydroxycholecalciferol-Ια-hydroxylase-enzymet i nyrekanalen. Virkningsretningerne af forbindelserne er følgende: 35 A) Virkninger med vitamin A-karakter: a) Farmakologiske og biokemiske virkninger:

3 forøgende virkning på kondroitinsulfatsyntese; gunstig virkning på sårhelingen eller på den ved indgift af kortison eksperimentelt forringede sårheling hos rotter og hunde; poten-tierende virkning på vitamin A's virkning hos rotter og høns ved 5 eksperimentelt fremkaldte hypo- eller hypervitaminoser; dæmpende virkninger på de ulcerations-betingede stress-virkninger hos rotter; begunstigende virkning på degranulationen af mastocyter; forøgende virkning på produktionen af lysozym; virkning på sporstofhusholdningen (silicium, zink, kobber, mangan, fluor); frem-10 mende virkning på epiteldannelsen; fremmende virkning på den alkaliske fosfataseaktivitet; virkningen på den ved lokal indvirkning af vitamin A fremkaldte granulomposedannelse (Granulomsack-bilding); det yderst flade forløb af dosis-virkningskurven eller ændringen af virkningens fortegn ved store doser; aktiverende 15 virkning på Golgi-apparatet; begunstigende virkning på dannelsen af slim- eller bægerceller; forøgende virkning på koncentrationen af vitamin A.
b) Klinisk-terapeutislce virkninger: keratokonjunktivis sicca; Sjogrens syndrom; rhino-laryngo-pharingitis sicca; ozæna; 20 kronisk bronchitis; sinobronchitis; mucoviscidose; konstitutionelle lungesygdomme hos småbørn; paradentose; hudens og slimhindernes smittetilbøjelighed for vira og svampe; kortison-antagonistisk virkning; gunstig virkning på helingen ved operationssår og slimhindesår; erosio colli; pruritusagtige lidelser; nedsættelse af 25 lugte- og smagssansen.
B) Virkninger uden vitamin A-karakter a) Farmakologiske og biokemiske virkninger: virkning på 30 blodsukkerniveauet med hensyn til en forbigående sænkning; forøgende virkning på fosfaturi, sænkende virkning på fosfatniveauet i serum; strålingsbeskyttende virkning; formindskende virkning på den nødvendige tid der går med at nå målet ved labyrintforsøg hos inaktiverede dyr; formindskende virkning på eksperimentelt frem-35 kaldte fluor- og kadmiumtoxikoser; forøgende virkning på den cykliske adenosinmonofosfat-udtømning af nyrerne; dæmpende virkning på symptomerne ved eksperimentelt fremkaldt lathyrismus; formindskelse af histaminfølsomheden; forøgende virkning på aktiviteten af leverenzymet tyrosinaminotransferase.

b) Terapeutiske virkninger: svage bestrålingsskader; vitiligo; muskelhypotoni; psykoenergetiserende virkning; gunstig virkning på involutionelle og gerontologiske tilstande samt på de mnestiske funktioner; keloide tilbøjeligheder; spondylosis 5 ankylopoetica; sygdomme hos bevægelsesorganerne på grund af slid; sclerotisk fundus; amyloidose; morphæa; fibrocytisk mastopati.
I veterinærmedicinen har de ifølge opfindelsen fremstillede forbindelser lignende anvendelsesområder som i humanmedicinen, dvs. fx hudskader (afskalning), sårheling og knoglebrud.
10 Fremgangsmåden ifølge opfindelsen er ejendommelig ved det i patentkravets kendetegnende del angivne.
Man går således ud fra ^-substitueret glutamin eller as-paragin eller substituerede derivater af disse. I dette tilfælde substitueres et af de syreamidhydrogenatomer, der har sur karak-15 ter, ved fremgangsmåden ifølge opfindelsen fx med metallisk natrium og den på denne måde vundne forbindelse omdannes ved omsætning med fx 2-bromætansulfonsyre-natriumsalt til en forbindelse med den almene formel I.
Fremgangsmåden ifølge opfindelsen belyses nærmere i 20 det følgende ved hjælp af et eksempel.

DK 159267 B
Eksempel 3,02 g (10 mmol) karbobenzyloxy-L-glutamin-natriumsalt (Liebigs Annalen 640, 145, 1961) opløses i 50 ml dimetylformamid.
Til opløsningen sættes en oliesuspension der indeholder 12 mmol natriumhydroxyd og derpå opvarmes der i to timer under udelukkelse af luftfugtigheden. Derpå sættes der dråbevis 2,11 g (10 mmol) brom-5 ætansulfonsur natrium i 50 ml dimetylformamid til Opløsningen og blandingen opvarmes i yderligere to timer. Derpå inddampes der under vakuum og remanensen ekstraheres med æter og tørres. Den tørre forbindelse opløses i vand, anbringes på en kolonne med MDowex" 50 og elueres med vand. Eluatet inddampes under vakuum og remanensen 10 tørres over kaliumhydroxyd. Der vindes råt karbobenzyloxy- γ-L-glutamyltaurin som renses ved papirelektroforese gennemført ved pH 6,5. Den relative bevægelighed i forhold til cysteinsyre * udgør 1,05.· R„ (n-Butanol/pyridin/iseddike/vand 15:10:3:12) = 0,57.

De ved fremgangsmaden ifølge opfindelsen fremstillede forbindelsers biologiske virkning skal i det følgende belyses i to biologiske forsøgsrapporter, A og B. I disse forsøgsrapporter vises den biologiske virkning for forskellige typer af for bindelser med den almene formel I. De undersøgte forbindelser 20 har alle ubeskyttede N-terminale og C-terminale grupper, dvs.
R^ er hydrogen og er hydroxy. Forbindelser med den almene formel I, hvor er forskellig fra hydrogen og/eller hvor A^ er forskellig fra hydroxy har den samme biologiske virkning som de tilsvarende ubeskyttede aminosyrederivater, idet man må for- 25 vente at beskyttelsesgrupperne fraspaltes i organismen.
