Compounds of the formula (1) :
or pharmaceutically acceptable salts thereof as described, wherein
is a pyridine, pyrazine or triazine ring; R¹ is C₁₋₆alkyl, C₂₋₆alkenyl, C₃₋₅cycloalkylC₁₋₆alkyl, or C₁₋₆alkyl substituted by 1 to 6 fluoro groups; R² is C₁₋₆alkylthio, C₁₋₆alkylsulphonyl, C₁₋₆alkoxy, hydroxy, hydrogen, hydrazino, C₁₋₆alkyl, phenyl, -NHCOR³ wherein R³ is hydrogen or C₁₋₆alkyl, or -NR⁴R⁵, wherein R⁴ and R⁵ together with the nitrogen atom to which they are attached form a pyrrolidino, piperidino, hexahydroazepino, morpholino or piperazino ring, or R⁴ and R⁵ are independently hydrogen, C₃₋₅cycloalkyl or C₁₋₆alkyl which is optionally substituted by -CF₃, phenyl, -S(O)nC₁₋₆alkyl wherein n is 0, 1 or 2, -OR⁶, -CO₂R⁷ or -NR⁸R⁹ wherein R⁶ to R⁹ are independently hydrogen or C₁₋₆alkyl, provided that the carbon atom adjacent to the nitrogen atom is not substituted by said -S(O)nC₁₋₆alkyl, -OR⁶ or -NR⁸R⁹ groups; and when
is a pyrazine ring it may be further substituted by hydroxy when R² is hydroxy.
Their use as medicaments, pharmaceutical compositions comprising them and processes for their preparation are also described.

是吡啶、吡嗪或三嗪环;R¹是 C₁₋₆ 烷基、C₂₋₆烯基、C₃₋₅环烷基、C₁₋₆ 烷基或被 1 至 6 个氟基团取代的 C₁₋₆ 烷基;R² 是 C₁₋₆alkylthio, C₁₋₆alkylsulphonyl, C₁₋₆alkoxy, hydroxy, hydrogen, hydrazino, C₁₋₆alkyl, phenyl, -NHCOR³ 其中 R³ 是氢或 C₁₋₆alkyl, 或 -NR⁴R⁵、其中 R⁴ 和 R⁵ 与它们所连接的氮原子一起形成吡咯烷、哌啶、六氢氮杂环、吗啉或哌嗪环,或 R⁴ 和 R⁵ 独立为氢、C₃₋₅环烷基或任选被 -CF₃、苯基、-S(O)nC₁₋₆ 烷基(其中 n 为 0、1 或 2)、-OR⁶取代的 C₁₋₆ 烷基、-CO₂R⁷或-NR⁸R⁹,其中 R⁶ 至 R⁹ 独立为氢或 C₁₋₆ 烷基、条件是与氮原子相邻的碳原子未被所述-S(O)nC₁₋₆烷基、-OR⁶或-NR⁸R⁹基团取代;当
是吡嗪环时,当 R² 是羟基时,可进一步被羟基取代。
