A compound which is a pyrrolopyrimidine of formula (I) wherein R1 is selected from H, Cl-C6 alkyl which is unsubstituted or substituted, (CH2)nAr1, (CH2)pNR4R5, halogen and (CH2)pX; R2 is CH2)pArl; R3 is selected from H, Cl -C6 alkyl which is unsubstituted or substituted, (CH2)pZ and (CH2)pArl; P is an unsaturated 5, 6, or 7 membered carbocyclic or heterocyclic ring which is unsubstituted or substituted; R4 and R5 which are the same or different are selected from H, Cl -C6 alkyl which is unsubstituted or substituted, (CH2)nC3-C10 cycloalkyl, (CH2)nAr1 , and (CH2)nOR6, or R4 and R5 together with the nitrogen atom to which they are attached, form a saturated five or six membered nitrogen containing heterocyclic ring which may contain one extra heteroatom selected from 0, N and S and which is unsubstituted or substituted; R6 is selected from H, Cl -C6 alkyl which is unsubstituted or substituted, C3-C10 cycloalkyl, (CH2)nOC1-C6alkyl which is unsubstituted or substituted, (CH2)nO(CH2)nAr1 , (CH2)nCO2C1-C6,alkyl which is unsubstituted or substituted and (CH2)nAr1; X is selected from CN, azide, (CH2)nNHSO2R6 and (CH2)nNHCOR6; Z is selected from CN, CO2R6 and CONR4R5; Ar1 is the same or different when more than one is present within a given substituent group and is an unsaturated C6-C10 membered carbocylic group or an unsaturated 5-11 membered heterocycle, either of which is unsubstituted or substituted; p is an integer of 1 to 6; n is the same or different when more than one is present within a given substituent group and is 0 or an integer of 1 to 6; with the proviso that the pyrrolepyrimidine compound of formula (I) is other than 1-(4-benzyl-piperazin-1-yl)-9H-2,4,9-triaza-fluorene; and the pharmaceutically acceptable salts thereof, have activity as inhibitors of MRP (multidrug resistant protein) and may thus be used to modulate multidrug resistance, for instance in potentiating the cytotoxicity of a chemotherapeutic agent.
化合物是一种公式为(I)的吡咯吡嘧啶,其中R1从H、未取代或取代的Cl-C6烷基、(CH2)nAr1、(CH2)pNR4R5、卤素和(CH2)pX中选择;R2为(CH2)pArl;R3从H、未取代或取代的Cl-C6烷基、(CH2)pZ和(CH2)pArl中选择;P为未取代或取代的不饱和5、6或7成员碳环或杂环;R4和R5相同或不同,从H、未取代或取代的Cl-C6烷基、(CH2)nC3-C10环烷基、(CH2)nAr1和(CH2)nOR6中选择,或者R4和R5与它们连接的氮原子一起形成饱和的含氮五元或六元杂环,可能含有一个额外的杂原子,选择自O、N和S,未取代或取代;R6从H、未取代或取代的Cl-C6烷基、C3-C10环烷基、(CH2)nOC1-C6烷基、未取代或取代的(CH2)nO(CH2)nAr1、未取代或取代的(CH2)nCO2C1-C6烷基和(CH2)nAr1中选择;X从CN、叠氮、(CH2)nNHSO2R6和(CH2)nNHCOR6中选择;Z从CN、CO2R6和CONR4R5中选择;Ar1当多个存在于给定的取代基组内时相同或不同,为未取代或取代的不饱和C6-C10成员碳环或未取代或取代的不饱和5-11成员杂环;p为1至6的整数;n当多个存在于给定的取代基组内时相同或不同,为0或1至6的整数;但是,公式(I)的吡咯吡嘧啶化合物不是1-(4-苄基哌嗪-1-基)-9H-2,4,9-三氮杂萘;其药学上可接受的盐具有作为MRP(多药耐药蛋白)抑制剂的活性,因此可用于调节多药耐药性,例如在增强化疗药物的细胞毒性方面。
