The present invention relates to a compound of formula (I), wherein X1, X2 and X3 are, independently of each other, N or CH; with the proviso that at least two of X1X2 and X3 are N; Y is N or CH; W is H or F; with the proviso that when W is F, then X1, X2 and X3 are N; R1 and R2 are independently of each other (i) a morpholinyl of formula (II) wherein the arrow denotes the bond in formula (I); and wherein R3 and R4 are independently of each other H, C1-C3alkyl optionally substituted with one or two OH, C1-C2fluoroalkyl, C1-C2alkoxy, C1-C2alkoxyC1-C3alkyl, CN, or C(0)0-C1- C2alkyl; or R3 and R4 form together a bivalent residue -R5R6- selected from C1-C3alkylene optionally substituted with 1 to 4 F, -CH2-0-CH2-, -CH2-NH-CH2-, or any of the structures wherein the arrows denote the bonds in formula (II); or (ii) a saturated 6-membered heterocyclic ring Z selected from thiomorpholinyl and piperazinyl, optionally substituted by 1 to 3 R7; wherein R7 is independently at each occurrence C1-C3alkyl optionally substituted with one or two OH, C1-C2fluoroalkyl, C1- C2alkoxyC1-C3alkyl, C3-C6cycloalkyl; or two R7 substituents form together a bivalent residue -R8R9- selected from C1-C3alkylene optionally substituted with 1 to 4 F, -CH2-0-CH2- or -0- CH2CH2-0-; with the proviso that at least one of R1 and R2 is a morpholinyl of formula II; and prodrugs, metabolites, tautomers, solvates and pharmaceutically acceptable salts thereof, for use in a method of treating a skin disorder in a subject, wherein said skin disorder is a genodermatosis, a vascular anomaly or a skin disorder selected from scleroderma, sclerodermatous chronic graft-versus-host disease, lichen sclerosus, lichen planus, lichen ruber planus and scars.
本发明涉及公式(I)的化合物,其中X1、X2和X3是独立的N或CH;但至少两个X1X2和X3是N;Y是N或CH;W是H或F;但当W为F时,X1、X2和X3是N;R1和R2是独立的(i)公式(II)的吗啡啶基,箭头表示公式(I)中的键;其中R3和R4是独立的H、C1-C3烷基(可选地取代一个或两个OH)、C1-C2氟代烷基、C1-C2烷氧基、C1-C2烷氧基C1-C3烷基、CN或C(0)0-C1-C2烷基;或R3和R4共同形成双价残基-R5R6-,所选自C1-C3烷基(可选地取代1至4个F)、-CH2-0-CH2-、-CH2-NH-CH2-或任何箭头表示公式(II)中的键的结构;或(ii)选择自硫代吗啡啶基和哌嗪基的饱和6元杂环Z,可选地取代1至3个R7;其中R7在每次出现时是独立的C1-C3烷基(可选地取代一个或两个OH)、C1-C2氟代烷基、C1-C2烷氧基C1-C3烷基、C3-C6环烷基;或两个R7取代基共同形成双价残基-R8R9-,所选自C1-C3烷基(可选地取代1至4个F)、-CH2-0-CH2-或-0-CH2CH2-0-;但至少有一个R1和R2是公式II的吗啡啶基;以及其前药、代谢产物、互变异构体、溶剂化物和在治疗主体的皮肤疾病的方法中使用的药物可接受的盐,其中所述的皮肤疾病是遗传性皮肤病、血管异常或选择自硬皮病、硬皮样慢性移植物抗宿主病、白苔样硬化、白苔样平苔藓、红斑平苔藓和疤痕的皮肤疾病。
