1. A method of inhibiting Axl activity in a mammalian cell, wherein the method comprises contacting the cell with an effective amount of a compound of formula (I): wherein: A is ═C(H)— or ═N—; R1 is —N(R2)R3, —N(R2)C(O)R3 or —N(R2)—R4—C(O)OR3; or R1 is an N-heterocyclyl optionally substituted by one or more substituents selected from the group consisting of halo and —R4—C(O)OR2; each R2 and R3 is hydrogen, alkyl, alkenyl, optionally substituted aralkyl, optionally substituted cycloalkyl, optionally substituted cycloalkylalkyl and optionally substituted heteroarylalkyl; and each R4 is independently selected from the group consisting of a direct bond and an optionally substituted straight or branched alkylene chain; as an isolated stereoisomer or mixture thereof, or a pharmaceutically acceptable salt thereof; provided that the compound of formula (I) is not a compound selected from the group consisting of: 1-(6,7-dihydro-5H-benzo[6,7]cyclohepta[1,2-c]pyridazin-3-yl)-N3-(7-(pyrrolidin-1-yl)-6,7,8,9-tetrahydro-5H-benzo[7]annulene-2-yl)-1H-1,2,4-triazole-3,5-diamine; 1-(6,7-dihydro-5H-benzo[6,7]cyclohepta[1,2-c]pyridazin-3-yl)-N3-(7-((bicyclo[2.2.1]heptan-2-yl)amino)-6,7,8,9-tetrahydro-5H-benzo[7]annulene-2-yl)-1H-1,2,4-triazole-3,5-diamine; 1-(6,7-dihydro-5H-benzo[6,7]cyclohepta[1,2-c]pyridazin-3-yl)-N3-(7-((bicyclo[2.2.1]heptan-2-yl)(methyl)amino)-6,7,8,9-tetrahydro-5H-benzo[7]annulene-2-yl)-1H-1,2,4-triazole-3,5-diamine; 1-(6,7-dihydro-5H-benzo[6,7]cyclohepta[1,2-c]pyridazin-3-yl)-N3-((7-piperidin-1-yl)-6,7,8,9-tetrahydro-5H-benzo[7]annulene-2-yl)-1H-1,2,4-triazole-3,5-diamine; 1-(6,7-dihydro-5H-benzo[6,7]cyclohepta[1,2-c]pyridazin-3-yl)-N3-((7-azetidin-1-yl)-6,7,8,9-tetrahydro-5H-benzo[7]annulene-2-yl)-1H-1,2,4-triazole-3,5-diamine; 1-(6,7-dihydro-5H-benzo[6,7]cyclohepta[1,2-c]pyridazin-3-yl)-N3-((7-(R)-pyrrolidin-1-yl)-6,7,8,9-tetrahydro-5H-benzo[7]annulene-2-yl)-1H-1,2,4-triazole-3,5-diamine; and 1-(6,7-dihydro-5H-benzo[6,7]cyclohepta[1,2-c]pyridazin-3-yl)-N3-(7-diethylamino-6,7,8,9-tetrahydro-5H-benzo[7]annulene-2-yl)-1H-1,2,4-triazole-3,5-diamine; or a pharmaceutical composition comprising a pharmaceutically acceptable excipient and a therapeutically effective amount of a compound of formula (I), as an isolated stereoisomer or mixture thereof, or a pharmaceutically acceptable salt thereof; and wherein the Axl activity in the mammalian cell is associated with a disease or condition in the mammal.
