Description
Područje tehnike kojoj izum pripada:
Int. klasa: C07D 491/02
C07D 491/12
Predstavljeni izum odnosi se na sinteze novih kumarin-kinolonskih karboksilnih kiselina kod kojih je piridonski sistem kondenziran na položajima 3,4 , 6,7 i 7,8 kumarinskog sistema prikazanih općom formulom I:
[image]
naznačene time da je: R1 R2 = -NHCH(CO2R6)CO ili -CO(CO2R6)CHNH, R3 = H ili NO2
ili NH2, R4 =H, R5 = H ili F, R6 = H ili C2H5; R1 R2 = R3 R4 = -NHCH(CO2R6)CO, R5 = H, R6 = H ili C2H5;
R1 = H ili OH, R2 = R5 = H, R3 R4 = -NHCH(CO2R6)CO, R6 = H ili C2H5;
R1 = OH, R2 = R3 = H, R4 R5 = -CO(CO2R6)CHNH, R6 = H ili C2H5;
R1 = R5 = H, R2 = CH3 ili CF3, R3 R4 = -CO(CO2R6)CHNH, R6 = H ili C2H5,
kao i njihove farmaceutski prihvatljive soli.
Predmet izuma su i postupci za pripravu novih kumarin-kinolonskih karbokstlnih kiselina, kao i njihovo biološko djelovanje.
U skladu s predstavljenim izumom, nove kumarin-kinolonske karboksilne kiseline predstavljene skupnom formulom I pripravljene su polazeći od malonatnih estera kumarina formule II, opisanih u Patentnoj prijavi broj P-960308 A od 2. srpnja 1996.
[image]
naznačenih time da je R1 = -NHCH=C(CO2C2H5)2, R2 = R3 = R4 = H, R5 = H ili F;
R1 = R3 = -NHCH=C(CO2C2H5)2, R2 = R4 = R5 = H;
R1 = H ili OH, R3 = -NHCH=C(CO2C2H5)2i R2 = R4 = R5 = H;
R1 = OH, R2 = R3 = R4 = H, R5 = -NHCH=C(CO2C2H5)2;
R1 = R3 = R5 = H)R2 = CH3 ili CF3, R4 = -NHCH=C(CO2C2H5)2,
koji su zagrijavani u Dowtherm A pri 250-260°C u trajanju od 10 minuta do 13 sati, pri čemu su dobijeni ciklizirani esteri opće formule III:
[image]
naznačeni time da je: R1 R2 = -NHCH(CO2C2H5)CO ili -CO(CO2C2H5)CHNH, R3 = R4 = H,
R5 = H ili F;
R1 R2 = R3R4 = -NHCH(CO2C2H5)CO, R5 = H;
R1 = H ili OH, R2 = R5 = H, R3R4 = -NHCH(CO2C2H5)CO;
R1 = OH, R2 = R3 = H, R4R5 = -CO(CO2C2H5)CHNH;
R1 = R5 = H, R2 = CH3 ili CF3, R3R4 = -CO(CO2C2H5)CHNH.
Za spoj formule III naznačen time da je R1 R2 = -CO(CO2C2H5)CHNH, R3 = R4 = H, R5 = H se u D. T. Connor, P. A. Voung, M. von Strandtman, J. Heterocyclyc Chem. 18 (1981) 697-702 izričito navodi kako je pokušaj ciklizacije odgovarajućeg malonatnog estera kumarina u ester formule III s gore naznačenim supstituentima bio neuspješan, te tako nije dobijena niti odgovarajuća kiselina, koja je, uz spomenuti ester formule III također predmet ovog izuma i predstavljena je općom formulom l naznačena time da je R1 R2 = -CO(CO2H)CHNH, R3 = R4 = H, R5 = H.
Spoj formule III naznačen time da je R1 R2 = -NHCH(CO2C2H5)CO, R3 = R4 = H, R5 = H (opisan ranije u: D. T. Connor (Warner-Lambert Companv) US Pat No. 4,210,758 od 1. srpnja 1980.) prvo je nitriran, zatim reduciran i konačno kondenziran s dietil-etoksimetilen malonatom pri čemu je dobijen spoj formule IV:

naznačen time da je R = NO2 ili NH2.
Hidrolizom spojeva prikazanih formulom III dobijene su kumarin-kinolonske karboksilne kiseline opisane formulom l u kojima R1, R2, R3, R4 i R5 imaju značenje prije opisano, dok je R6 = H.
Kumarin-kinolonske karboksilne kiseline, koje su predmet ovog izuma, kao i njihove farmaceutski prihvatljive soli, pokazuju inhibiciju prema ispitivanim sojevima bakterija. U ovim se ispitivanjima koristio mikrodilucijski test za ispitivanje osjetljivosti bakterija prema metodi: NCCLS (M7-A2, vol. 10. No 8, 1990; M100-S4, vol. 12, No 20, 1992). Kontrolni test mikroorganizmi korišteni u ovim pokusima su: S. aureus ATCC 29213, E. faecalis ATCC 29212 i P. aeruginosa ATCC 29213, uz norfloksacin i enorfloksacin kao radne standarde antibiotika za usporedbu. Ispitivanje je obavljeno na slijedećim sojevima: Staphiloc. aureus ATCC 6538P, Bacillus subtilis NCTC 8236, Micrococcus flavus ATCC 10240, Pseudomonas aerug. NCTC 10490, Salmonela Panama 6117, E. coli Lac+ 6131, E. coli Lac- 6130, b-Haemol. streptococc. - B J-22, b-Haemol. streptococc. - A J-21, Streptococcus pyogenes 20F, Streptococcus faecalis ATCC 8043, E. co//ATCC 10536, Staphyloc. epidermis ATCC 12228, 5. cereusAVCC 11778, S. pumilus ATCC 8241 i S. subtilis AJCC 6633.
4,5-Dihidro-4,5-diokso-1 H-[1]-benzopirano[4,3-6]piridin-3-karboksilna kiselina pokazuje inhibiciju prema E. co//Lac+ 6131 i prema b-Haemol. streptococc. - A J-21.
1,5-Dihidro-1,5-diokso-7-fluor-4 H-[1]-benzopirano[3,4-b]piridin-3-karboksilna kiselina pokazuje inhibiciju prema ispitivanim sojevima.
4,7-Dihidro-4,7-diokso-1 H-[1]-benzopirano[6,7-b]piridin-3-karboksilna kiselina pokazuje inhibiciju prema Bacillus subtilis NCTC 8236, Streptococcus pyogenes 20F i Streptococcus faecalis ATCC 8043.
Kumarin-kinolonske kiseline predstavljene ovim izumom i njihove farmaceutski prihvatljive soli ispitivane su i na antitumorski učinak in vitro. Testiran je antitumorski učinak na rast staničnih linija karcinoma dojke (MCF7), karcinoma grlića maternice (HeLa), karcinoma pankreasa (MiaPaCa2), karcinoma larinksa (Hep2) i normalnih fibroblasta čovjeka (Hef5229.
1,7-Dihidro-1,7-diokso-9-(trifluormetil)-4H-[1]-benzopirano[6,7-b]piridin-3-karboksilna kiselina inhibira rast stanica karcinoma dojke (MCF7), karcinoma pankreasa (MiaPaCa2) i karcinoma larinksa (Hep2), te lagano potiče rast stanica karcinoma grlića maternice (HeLa), u višim koncentracijama. Na rast fibroblasta (Hef522) nema značajnijeg djelovanja.
Rast MCF7 inhibiran je ovisno o koncentraciji, a najbolja inhibicija postiže se pri 10-5 i 10-8 M.
Na rast HeLa stanica nema utjecaja u području koncentracija od 10-8 - 10-6 M, dok pri višim koncentracijama (10-5 i 10-4 M) potiče nijhov rast.
Rast stanica MiaPaCa2 inhibiran je ovisno o koncentraciji. Pri koncentraciji 10-4M polučena inhibicija je 35%.
Ispitivana supstanca inhibira rast Hep2 stanica, s povećanjem koncentracije smanjuje se inhibitorni učinak, a najbolji rezultati su u područjima koncentracija 10-7 i 10-5 M.
Ispitivana supstanca nema utjecaja na rast normalnih fibroblasta (Hef522).
