N,N-di(aryl) cyclic urea derivatives as anti-coagulants
摘要：
N,N-di(aryl) cyclic urea derivatives, such as the compounds of the following formula: ##STR1## wherein R.sup.1 is --C(NH)NH.sub.2, --C(NH)N(H)OR.sup.11, --C(NH)N(H)C(O)R.sup.9, or --C(NH)N(H)C(O)OR.sup.11 ;R.sup.2 and R.sup.3 are independently hydrogen, halo, lower alkyl, lower haloalkyl, aryl, --OR.sup.11, --C(O)OR.sup.11, --C(O)N(R.sup.11)R.sup.12, --N(R.sup.11)R.sup.12, --N(H)C(O)R.sup.11, or --N(H)S(O).sub.2 R.sup.11 ;R.sup.4 is halo, lower haloalkyl, imidazolyl, --C(NH)NH.sub.2, --C(NH)NHOR.sup.11, --C(NH)N(H)C(O)R.sup.9, --C(NH)N(H)C(O)OR.sup.11, --OR.sup.11, --C(O)R.sup.13, --(CH.sub.2).sub.n C(O)OR.sup.11 (where n is 0 to 6), --C(O)N(R.sup.11)R.sup.12, or --N(R.sup.11)R.sup.12 ;R.sup.7 and R.sup.8 are independently hydrogen, lower alkyl, lower haloalkyl, 4-pyridinyl, --C(O)OR.sup.11, --C(O)N(R.sup.11)R.sup.12, or aryl (optionally substituted by one or more substituents selected from the group consisting of halo, hydroxy, lower alkyl, lower haloalkyl, lower alkoxy and --N(R.sup.11)R.sup.12);R.sup.11 and R.sup.12 are independently hydrogen, lower alkyl, aryl or lower aralkyl; orR.sup.13 is pyrrolidinyl, 4-morpholinyl, piperazinyl, N-methylpiperazinyl, or piperidinyl; or a pharmaceutically acceptable salt thereof, are disclosed herein as being inhibitors of factor Xa and thereby being useful as anticoagulants.
