Abstract
Zpusob prípravy epothilon-N-oxidu, pri nemž se chránený nebo nechránený epothilon A nebo B prevede na N-oxid, zejména peroxykyselinou nebo dioxiranem. Epothilon A-N-oxid a epothilon B-N-oxid.
Description
Způsob přípravy epothilon-N-oxidů a N-oxidy epothilonů
Oblast techniky
Epothiolony A a B jsou známé; srovnej například DE 4 138 042, WO 93 10121 a WO 97 19086. Jmenovaný stav techniky je navrhuje jako terapeutické prostředky.
Dosavadní stav techniky
V PNAS USA 95 (1998) 1369 - 1374 jsou epothilony označovány jako užitečné terapeutické prostředky. V důsledku jejich terapeutických efektů se podle Angew. Chem. Int. Ed. 36 (1997) 2097 - 2103 bude dokonce opatřovat obsáhlá knihovna sloučenin tohoto druhu (extensive library of compounds).
Podstata vynálezu
Vynález se týká způsobu přípravy epothilon-N-oxidů, při němž se chráněný nebo nechráněný epothilon A nebo B o sobě známým způsobem převede na N-oxid.
Tento postup podle vynálezu je s výhodou charakterizován tím že se N-oxidace provádí peroxykyselinou nebo dioxiranem.
Předmětem vynálezu je rovněž epothilon-N-oxid (epothilon A-N-oxid) vzorce
r1, r2 = h, z = o; r = h
Dále je předmětem vynálezu epothilon-N-oxid (epothilon B-N-oxid) vzorce:
r1,r2 = h, z = o; r = ch3

Příklady provedení vynálezu
Příklad 1
Epothilon A-N-oxid
Ke 100 mg epothilonu A v 1 ml dichlormetanu bylo přidáno 100 mg 70% kyseliny w-chlorperoxybenzoové v 0,5 ml dichlorethanu. Po 6 hodinách míchání při teplotě místnosti bylo zředěno dichlormethanem a postupně vytřepáváno roztokem siřičitanu sodného a roztokem bikarbonátu sodného k odstranění přebytečné peroxykyseliny. Rozpouštědlo bylo odpařeno ve vakuu a zbytek byl rozdělen preparativní HPLC na sloupci Nucleosilu RP-18 (250 x 20 mm, mobilní fáze methanol/voda 60:40). Výtěžek 60 mg bezbarvého oleje.
Rf= 0,60 (silikagel DC Alufolie, mobilní fáze dichlormethan/methanol 1:1);
ESI-MS (negativní ionty) m/z 510;
UV (methanol): Zmax = 240 nm;
13C-NMR (CDC13): C-l 70,5, C-2 39,9, C-3 70,8, C^l 55,1, C-5 221,4, C-6 40,9, C-7 72,9, C8 37,6, C-9 31,8, C-10 22,8, C-l 1 28,0, C-12 58,0, C-13 55,8, C-14 32,2, C-15 75,5, C-16 144,5, C-17 111,4, C-18 143, 4, C-19 110,3, C-20 145,6, C-21 13,5, C-22 15,4, C-23 23,3, C24 12,0, C-25 16,5, C-27 18,2 ppm.
Příklady syntéz
Epothilon A-N-oxid: R1, R2 = H, Z = O', R = H
Epothilon B-N-oxid: R1, R2 = H, Z = O', R = CH3
