Description
Predloženi izum odnosi se na 2-supstituirane derivate 1,2-benzoizotiazola, njihovo pripravljanje i upotrebu za proizvodnju aktivnih sastojaka lijekova.
Klasični antidepresanti i noviji selektivni inhibitori ponovnog uzimanja serotonina (SSRIs), razvijaju svoj učinak antidepresanta, između ostalog, inhibicijom aktivnog ponovnog uzimanja transmitera u presinaptičke završetke živaca. Na nesreću, njihov antidepresantni učinak se uspostavlja najmanje tek tri tjedna nakon liječenja, i čak štoviše, pribl. 30% pacijenata je rezistentno prema terapiji.
Blokada presinaptičkih serotonin autoreceptora se povisuje, poništavajući negativno vezanje, serotonin se oslobađa i time stvarna koncentracija transmitera u sinaptičkom procjepu. To povišenje koncentracije transmitera se smatra načelom antidepresantnog učinka. Taj mehanizam djelovanja razlikuje se od ranije poznatih antidepresanata, koji aktiviraju oboje, presinaptičke i somatodendritičke autoreceptore, i zbog toga imaju za posljedicu odgođeno uspostavljanje djelovanja, samo nakon desenzitizacije tih autoreceptora. Izravna blokada autoreceptora premošćuje taj učinak.
Poznato je da, iako derivati tiazola opisani u DE 3620643 imaju afinitet za 5-HT1A receptore, oni nemaju afiniteta za 5-HT1B.
Prema sadašnjem znanju, presinaptički autoreceptor serotonina je 5-HT1B podtip (Fink et al., Arch. Pharmacol. 352 (1995), 451). Njegova selektivna blokada s 5-HT1B/D antagonistima povisuje oslobađanje serotonina u mozgu; G.W. Priče et al., Behavioural Brain Research 73 (1996), 79-82; P.H. Hutson et al. , Neuropharmacologγ Vol. 34, br. 4 (1995), 383-392.
Iznenađujuće, međutim, nakon sistemskog davanja, selektivni 5-HT1B antagonist GR 127 935 smanjuje oslobađanje serotonina u korteksu. Jedno objašnjenje može biti stimulacija somatodentritičkih 5-HT1B receptora u području rafa oslobađanjem serotonina, koji inhibira brzinu zapaljenja serotonergnih neurona i stoga oslobađanje serotonina (M. Skingle et al., Neuropharmacology Vol. 34 br. 4 (1995), 377-382, 393-402).
Stoga je jedna strategija za premošćivanje autoinhibicijskih učinaka u serotonergnim područjima izvorno usmjerena na blokiranje presinaptičkih 5-HT1B receptora. Tu hipotezu podupiru opažanja da se učinak paroksetina na oslobađanje serotonina u leđnoj rafe jezgri štakora pojačava s 5-HT1B recetor antagonistom GR 127 935 (Davidson i Stamford, Neuroscience Lett., 188 (1995), 41).
Druga strategija uključuje blokadu obaju tipova autoreceotora, naime 5-HT1A receptora, da se pojačaju neuronski signali, i 5-HT1B-receptora, da se poveća terminalno oslobađanje serotonina (Starkeγ i Skingle, Neuropharmacologγ 33, (3-4) (1994), 393).
5-HT1B/D antagonisti, sami ili povezani na antagonističku komponentu 5-HT1B receptora, trebali bi stoga uzrokovati pojačano oslobađanja serotonina u mozgu i zbog toga se mogu korisno povezati s terapijom depresija i srodnih psiholoških poremećaja.

Gore opisane reakcije odvijaju se općenito u inertnom organskom otapalu, npr. dimetilformamidu, acetonitrilu, diklormetanu, dimetil sulfoksidu, dimetoksietanu, toluenu, etil acetatu, ksilenu, ketonu kao što je aceton ili metil etil keton, alkoholu kao što je etanol ili n-butanol, ili cikličkom zasićenom eteru, npr. tetrahidrofuranu ili dioksanu.
Reakcije se općenito odvijaju pri 20°C do vrelišta otapala i općenito su gotove za 1 do 20 sati. Po potrebi, može biti prisutno sredstvo za vezanje kiseline, kao natrijev ili kalijev karbonat, natrijev metoksid, natrijev etoksid, natrijev hidrid, organometalni spojevi (butil-litij, alkilmagnezijevi spojevi), kalijev t-butoksid, piridin ili trietilenamin.
Tako gdje je to prikladno reakcije se odvijaju uz upotrebu katalizatora kao što su prijelazni metali i njihovi kompleksi, npr. Pd-C, Pd(PPh3)4, Pd(OAc)2, Pd(P(oTol)3)4, Pd2(dba)3 ili Ni (GOD)2.
Sirov proizvod izolira se na uobičajen način, na primjer filtracijom, odstranjivanjem otapala destilacijom ili ekstrakcijom iz reakcijske smjese.
Novi spojevi formule I mogu se očistiti prekristalizacijom iz uobičajenih organskih otapala ili kromatografijom na stupcu.
Osim derivata slobodnih 2-supstituiranog 1,2-benzo-izotiazola, izum također uključuje i kiselinske adicijske soli spojeva formule I s fiziološki podnošljivim kiselinama. Primjeri prikladnih fiziološki podnošljivih organskih i anorganskih kiselina jesu solna kiselina, bromovodična kiselina, fosforna kiselina, sumporna kiselina, oksalna kiselina, maleinska kiselina, fumarna kiselina, mliječna kiselina, vinska kiselina, adipinska kiselina ili benzojeva kiselina. Daljnje kiseline, koje se mogu upotrijebiti, opisane su u "Fortschritte der Arzneimittelforschung", Vol. 10, str. 224 i dalje, Birkhauser Verlag, Basel i Stuttgart, 1966.
Kiselinske adicjske soli proizvedene su na uobičajen način miješanjem slobodne baze s odgovarajućom kiselinom, ako je prikladno u otopini u organskom otapalu, na primjer nižem alkoholu kao što je metanol, etanol ili propanol, eteru, kao što je metil t-butil eter, ketonu kao što je aceton ili metil etil keton ili esteru kao što je etil acetat.
S tim u skladu izum se također odnosi na terapeutski sastav koji, pored uobičajenih nosača i sredstava za razrađivanje, kao aktivnu tvar sadrži spoj formule I ili njegovu farmakološki podnošljivu kiselinsku adicijsku sol, te na upotrebu novih spojeva za suzbijanje bolesti.
Novi spojevi mogu se dati na uobičajen način oralno ili parenteralno, intravenski ili intramuskularno.
Doziranje ovisi o starosti, stanju i težini pacijenta, te o načinu davanja. U pravilu kod oralnog davanja dnevna doza aktivne tvari iznosi od pribl. 1 do 100 mg/kg tjelesne težine i od 0,1 i 10 mg/kg tjelesne težine kod parenteralnog davanja.
Novi spojevi mogu se primijeniti u uobičajenim krutim ili tekućim farmaceutskim oblicima, npr. kao neprevučene ili (s filmom) prevučene tablete, kapsule, puderi, granule, čepići, otopine, masti, kreme ili sprejevi. Oni se proizvode na uobičajen način. U tu svrhu se aktivne tvari mogu preraditi s uobičajenim farmaceutskim pomoćnim sredstvima kao što su veziva za tablete, punila, konzervansi, sredstva za dezintegraciju tableta, sredstva za regulaciju tečenja, omekšivači, sredstva za kvašenje, sredstva za dispergiranje, emulgatori, otapala, sredstva usporavanje oslobađanja aktivne tvari, antioksidanti i/ili potisni plinovi (usporedi H. Sucker et al. : Pharmaceutische Technologie, Thieme-Verlag, Stuttgart, 1978). Tako dobiveni oblici za davanje sadrže aktivnu tvar normalno količinom od l do 99 mas. %.
Novi spojevi imaju visoki afinitet za receptore serotonina 5-HT1B, 5-HT1D i 5-HT1A. Pri tome, afinitet za te receptore je otprilike jednake veličine, barem istog reda veličine. Nadalje, neki od novih spojeva pokazuju dobru inhibiciju ponovnog uzimanja serotonina, što je načelno prisutno kod većine antidepresanata.
Ti spojevi su prikladni kao lijekovi za liječenje patofizioloških stanja kod kojih je snižena koncentracija serotonina i kod kojih se u okviru terapije želi ciljano blokirati aktivnost presinaptičkih receptora 5-HT1B, 5-HT1A i 5-HT1D, a da se pri tome ne utječe jako na druge receptore. Takovo bolesno stanje je primjerice depresija.
Spojevi predloženog izuma mogu se također upotrijebiti i za liječenje poremećaja raspoloženja uvjetovanog središnjom nervozom, kao što su sezonski osjećajni poremećaji i distimije. Tu spadaju također i stanja straha, kao opći strah, napadi panike, sociofobija, opsesivno-kompulzivne neuroze i simptomi post-traumatskog stresa, poremećaji pamćenja, uključiv demenciju, amneziju i gubitak pamćenja zbog starosti, kao i psihogene poremećaje uzimanja hrane kao što je neurotična anoreksija i neurotična bulimija.
Osim toga, spojevi prema izumu mogu se upotrijebiti za liječenje endokrinih bolesti, kao hiperprolaktinemije i za liječenje vazospazmi (naročito moždanih krvnih žila), hipertenzije i gastrointestinalnih poremećaja koji su povezani s poremećajima motiliteta i sekrecije. Daljnje područje primjene su seksulani poremećaji.
Slijedeći primjeri služe za objašnjenje izuma, bez namjere njegovog ograničenja.

Pripravljanje krajnjeg spoja
1,5 g (7,1 mmolova) amina 25a otopi se u 20 ml metanola i najprije se doda 3,8 g (28,4 mmolova) cinkovog klorida i 2,21 g (9,2 mmolova) aldehida opisanog u primjeru 23c otopljenog u 15 ml metanola i zatim se u obrocima doda 0,89 g (14,2 mmolova) natrijevog cijanobor-hidrida. Nakon 6 sati miješanja neotopljeno se odfiltrira i matičnicu se zgusne i preuzme u etil acetat. Organsku fazu se ispere s vodom i zasićenom otopinom soli, osuši preko natrijevog sulfata i zgusne, čime se dobije žućkasto ulje. Iskorištenje: 2,2 g (65% od teorijskog).
1H-NMR: (270 MHz, CDCl3) δ = 1,7-1,9 (m, 8H); 2,0 (m, 2H); 2,7-3,0 (m, 4H); 3,2 (m, 2H); 3,5 (m, IH); 3,7 (t, 2H);
